    Network Design Strategies | killexams.com true questions and Pass4sure dumps

    This chapter, from Upgrading and Repairing Networks, 5e, looks at the network's ratiocinative and physical design to assist your planning when creating a recent network.

    This chapter is from the book 

    Many types of networks were discussed in Chapter 1, "A Short History of Computer Networking," from ARPANET to TCP/IP. And in Chapter 2, "Overview of Network Topologies," you erudite about the various topologies you can employ when designing and creating a local belt network (LAN), and they moreover looked at some scenarios in which several networks were connected to form a wide belt network (WAN). In this chapter, they will inspect at another aspect of creating a network: the network's ratiocinative and physical design. The physical aspects of your LAN will depend on the underlying physical transport technology—Ethernet or Token-Ring, for example, or possibly ATM, which is supported as a LAN protocol in products such as Windows 2000/XP, Windows Server 2003, and Linux. Depending on which technology you use, there will live one or more LAN topologies from which to choose.

    Before you can launch to design a physical network, however, you first must determine your needs. What services must you provide to your user community? What are the resources you'll need? If you indulge in to compromise, what will it filch to fullfil the most users or to provide the more valuable services? You then will indulge in to filch into account network protocols, applications, network speed, and, most important, network security issues; each of these figures into a network's ratiocinative design. Another valuable factor your management will probably compel you to deem is cost—you can't forget the budget. These factors create up the ratiocinative design for your network. You first should choose what you necessity and what it will filch to provide for those needs.

    If you are creating a recent network and purchasing recent applications, you will probably spend most of your time considering the licensing and other financial costs (training users, network personnel, and so on). If you are upgrading older applications, several other factors Come into consideration. Many applications that were coded using COBOL, BASIC, FORTRAN, and other languages that helped jumpstart the computer age may indulge in built-in network functionality based on older proprietary network protocols. If this is the case with your network, you indulge in to deem several things. What will it cost to update thousands of lines of code (or more) to more modern versions of the selfsame programming language? What will it cost to upgrade these programs to newer object-oriented languages? To redeem money, can you upgrade participate of your network and utilize gateway hardware/software to connect to older network components?

    Because of the costs associated with coding applications that were created many years ago, and the expenses that will live required to update them to modern programming languages, you may live forced to maintain legacy applications for a few years while replacement applications are designed and created. You may find a packaged application that can live used to replace older programs. This problem will apply mostly to proprietary computer architectures, instead of Windows or Unix platforms. If you can simply create minor changes and compile the source code so that it will rush on a newer operating system, your costs will live much less than if you indulge in to re-create the applications your users necessity from scratch. Another cost associated with upgrading to recent programs is training users and help-desk personnel.

    When you plan a ratiocinative network design, you can start from one of two places. You can design and install a recent network from scratch, or you can upgrade an existing network. Either way, you should assemble information about several valuable factors before you launch the ratiocinative design. For example, depending on the services that will live provided to clients, you might necessity to anatomize the possible traffic patterns that might result from your plan. Locate potential bottlenecks and, where possible, alleviate them by providing multiple paths to resources or by putting up servers that provide replicas of valuable data so that load balancing can live provided. The following are other factors to consider:

  • Who are the clients? What are their actual needs? How indulge in you determined these needs—from user complaints or from help-desk statistics? Is this data reliable?
  • What kinds of services will you provide on the network? Are they limited in scope? Will any involve configuring a firewall between LANs? And if so, that still doesn't account for configuring a firewall to enable access to the Internet.
  • Will you necessity to allow an Internet connection for just your internal network's users, or will utilize you necessity to allow outside vendors access to your network? One illustration that comes to wit is the Internet Printing Protocol (see Chapter 24, "Overview of the TCP/IP Protocol Suite"). What will it cost to evaluate what kind of services user groups necessity to access from the Internet? Will you necessity to allow sum users to utilize email—both within the internal network and through the firewall on the Internet? The selfsame goes for what sites users will live allowed to access using a network browser and other network applications. Will you indulge in users who work from home and require dial-in or VPN access through the Internet?
  • Can your users tolerate a minute downtime now and then due to network problems, or is it necessary to provide a high-availability network? Will you necessity clustered servers to provide for a towering degree of uptime, or enact your users' applications not suffer from a temporary loss of the utilize of a server? To provide for maximum uptime, can you afford to build redundancy into your network? For example, Chapter 2 discusses redundant topologies that can live used to preclude a sole point of failure from making the network (and its resources) unavailable. Chapter 11, "Network Attached Storage and Storage belt Networks," describes methods you can utilize to mirror data at geographically distant locations.
  • In an existing network, will you retain the current protocol or upgrade to a different protocol standard? If you create a network from scratch, what factors should move your network protocol decision? Ethernet is the most common LAN technology in the world today. TCP/IP is the most common protocol suite that runs on Ethernet. Yet there are cases in which other technologies indulge in their niches. deem the implications (such as advocate costs and security) to maintain older, proprietary protocols.
  • Who Are Your Clients?

    This seems love a very simple question. However, I'm not saying, "What are your clients' names and how well enact you know their children?" I am referring instead to your learning of the job descriptions for the users on the network. You necessity to assess work patterns for various departments so that you can appropriately region servers, high-bandwidth links, and other such things in the preempt physical location of the network. If most of the network traffic you hope to observe will Come from the engineering department, you'll necessity to provide that department with a great data pipe. In Chapter 4, "Upgrading Strategies and Project Management," you'll find more information about surveying the user community to Come up with a plan that places resources where they are needed.

    What Kinds of Services or Applications Will the Network Offer?

    Of course, everyone knows that the most valuable role of a network today is to advocate multiuser gaming. Seriously, though, you necessity to create a list of the kinds of applications currently in use, as well as a list of those requested by users. Each application should indulge in a written risk assessment document that points out potential security problems, if any. Typical network applications today embrace FTP, telnet, and, of course, browsing the Web. There are "secure" versions of these applications and there are versions that leave a door wide open into your network. Whatever list of applications you chose to advocate over the network, retain in wit two things:

  • Is the application safe? Most applications today Come in secure versions or can live used with a proxy server to advocate minimize the possibility of abuse. Yet, as they sum indulge in seen, even the largest corporations are targets at times, and those companies indulge in the staff that should live able to preclude these things from happening. Because proxy servers are an valuable component of firewalls, this subject is covered in greater detail in Chapter 45. If you want a secure network, this is highly recommended reading!
  • Does one application overlap another? Every user has his or her favorite application. Some people love one word processor, whereas others prefer a different one. But when dealing with applications or application suites (such as Microsoft Office), you'll find it better to create a conclusion and stick with a sole product if it can fullfil the needs of your users. They might not love it, and training might live necessary, but supporting multiple applications that enact the selfsame thing wastes money and leads to confusion.
  • A commonly overlooked fashion for getting data files out of a network and onto the Internet is to simply ship the files as an attachment to an email. So if you mediate you've blocked file transfers by disabling FTP access through the firewall, this illustration should note that you really enact necessity to enact a thorough evaluation of any recent application or service you will allow on the network. recent applications should live justified with facts that note why they are needed. If an existing application can live used to accomplish the selfsame goal, why enact you necessity another application? Should you retire the older application and utilize a newer one? Pay attention to the details. And don't forget to test recent applications to ensure that they achieve as expected. The selfsame goes for older applications—will they work on the recent or upgraded network?

    Lastly, enact you monitor network usage? enact you want to permit users to spend their days browsing the Net, or checking personal email while at work? Many companies indulge in policies that apply to using the telephone for personal business. enact you overlook this situation when giving users email capability? Are you preventing access to sites that are obviously not business-related?

    What Degree of Reliability enact I Require for Each Network Link?

    Just how much downtime is acceptable? For most users, the own would live zero. valuable components of your network, such as file servers, should indulge in failing tolerance built in from the bottom up. In great servers, you'll find dual-redundant power supplies (each connected to a sunder UPS), and disk arrays set up using RAID techniques to provide for data integrity in the event that a disk goes south. If a link between two offices needs to live up 100% of the time, you should plan for multiple links between the two sites to provide a backup capability. In this case, you moreover can warrant the cost of the extra link by using load balancing so that network response time is improved. And, if you are using multiple links to remote sites, it's always a kindly sentiment to indulge in more than a sole path to the site. At one site this author worked at, there were redundant power lines bringing electricity into the site—side-by-side. If a tree falls, will it bring down one or both of those power lines?

    Another technology that can live used to provide an extra layer of redundancy, as well as high-speed access to storage devices, is the Storage belt Network (SAN). A SAN is a network that is sunder from the LAN and contains only storage devices and servers that necessity to access those devices. Because the network bandwidth is not shared with LAN users, multiple servers can access the selfsame storage. If one server fails, other servers can live configured to provide redundant access to the data. Also, the selfsame RAID and other redundancy techniques used for storage devices that are directly attached to a server (such as the SCSI hardware and protocols) can live used on a SAN.

    arrow.jpg

    The terms RAID and UPS are valuable in today's networks, as is the concept of load balancing and dual-redundant power supplies in great networks. You can find out more about RAID (Redundant Array Of Independent Disks) and UPSs (uninterruptible power supplies) by reading Chapter 5, "Protecting the Network: Preventative Maintenance Techniques." For more information about SANs, observe Chapter 11.

    The customary saw "If it ain't broke, don't fix it" doesn't apply to networks. You should always live proactively looking for potential sole points of failure and doing something to fix them. By building redundancy into the network design at the start, you'll redeem yourself a lot of grief in the future.

    Chapter 5 can give you more suggestions about using clustering, backups, uninterruptible power supplies, and other techniques that can retain the network up and running.

    Choosing a LAN Protocol

    Today the de facto protocol of option has to live TCP/IP. However, other protocols indulge in their region in some upright markets. In this book, they talk about NetWare. NetWare has been around so long that you might find you indulge in no option when designing an upgrade but to retain using IPX/SPX, depending on the applications your network uses. However, even NetWare has moved toward using TCP/IP as the underlying protocol. This is basically the case for version 5.x and 6.x of NetWare. Older NetWare networks should upgrade, if possible, to one of these newer versions. If you will live connecting the network to the Internet, TCP/IP will live a necessity. Even if you don't hope to indulge in an Internet connection, you'll find that choosing TCP/IP is a more practical option today because most applications work with it and there is a great market of trained professionals who can live hired to manage a network built on TCP/IP. NetWare 6.x provides backward compatibility with IPX/SPX for the most part, but newer features such as the iPrint—which uses the Internet Printing Protocol—require TCP/IP.

    In addition to transport protocols such as TCP/IP and IPX/SPX, you must deem application protocols that can live used on the network. For example, to simplify administering configuration information for a great number of computers, you might want to utilize the Dynamic Host Configuration Protocol (DHCP), which is discussed in Chapter 28, "BOOTP and Dynamic Host Configuration Protocol (DHCP)." If you want to provide a central appellation resolution service, you might choose the Domain appellation Service (DNS), which is covered in Chapter 29, "Network appellation Resolution." If you are going to operate a Windows network that has pre–Windows 2000/XP clients, you might necessity to utilize the Windows Internet Naming Service (WINS) for backward compatibility.

    So when thinking about a network protocol, recollect that it's not just one protocol you necessity to worry about. After you've decided which protocols are necessary, research the security implications of each.

    It's Virtually Universal: TCP/IP

    For sum practical purposes, the standard LAN protocol today is TCP/IP. This is partly due to the rapid growth of the Internet, and the necessity of most businesses of having a Web presence, as well as the great number of vendors that indulge in adopted this protocol suite. If your LAN is still using an older proprietary network protocol, you should seriously deem what it would filch to upgrade to TCP/IP. Currently, TCP/IP version 4 is the most widely used protocol. In the future you can hope that the next version (IPv6) will start to find its artery from the core of the Internet out to the edge, where your network resides. While technologies such as Network Address Translation (NAT) are widely employed to remedy the problem associated with the limited address space provided by IPv4, IPv6 will enable a much larger address space. Combine that with Network Address Translation, and the long-term bets are going to live on IPv6, or possibly some of the features that are participate of IPv6. In addition to giving you a larger address space, IPv6 includes other valuable features. Those that will move your network the most are security mechanisms, which will only become more valuable as Internet commerce continues to grow.

    arrow.jpg

    For a circumstantial introduction to TCP/IP, observe Chapter 24, "Overview of the TCP/IP Protocol Suite"; Chapter 25, "Basic TCP/IP Services and Applications"; and Chapter 27, "Troubleshooting Tools for TCP/IP Networks."

    There is one very valuable judgement you should deem TCP/IP as a LAN protocol: There are more trained professionals knowledgeable in TCP/IP than any other LAN protocol at this time. It is titillating to note that in Windows NT 3.51, the default network protocol was Microsoft's implementation of IPX/SPX (NWLink). In Windows NT 4.0 (and successive operating systems, from Windows 2000, XP, and Server 2003), the default network protocol is TCP/IP.

    If your network is composed of several operating systems, from Windows to NetWare to Unix and Linux, then the bottom line is that TCP/IP is the lowest common denominator that will allow the easiest connectivity and interaction between sum of these. Even Microsoft's now-legacy NetBIOS/NetBEUI protocols indulge in been adapted to rush over TCP/IP.

    Novell's NetWare Version 6.5

    NetWare was perhaps the first attempt at seriously providing a LAN protocol that was easy to use. The basic file and print services offered by early versions of NetWare were much better than other solutions available at that time. After it became established in the traffic community, NetWare became the network solution of option in many traffic environments that used the PC. Microsoft countered this success with its LANManager products, which were moreover marketed by other vendors in their own way, such as the Pathworks solution from Digital rig Corporation.

    Today NetWare is a totally revamped solution to LAN connectivity. It provides many recent features that are addressed to specifically create utilize of the Internet, and allow mobile users to connect to their home networks, as well as to enable NetWare users to create connections to outside networks. For example, the iPrint feature enables NetWare users to print to a printer on a remote network. For example, instead of sending a catalog that may live out of date in a month or so, you can utilize iPrint to periodically ship specific information apropos to each customer, by printing it directly to the customer's printer.

    And NetWare's iFolder allows mobile users to synchronize data stored on remote computers (such as a laptop computer) with the data stored on the company's network. Microsoft and other vendors proffer similar features. However, the point to recollect is that if you already are a NetWare user, you don't indulge in to pitch out your existing investment and scramble to a Microsoft network, or even a Unix/Linux environment. NetWare has changed as the market has changed, and you might find it less expensive to upgrade to NetWare 6.5 than to migrate to another platform. The bottom line involves not just the cost of migrating to another operating system, but the costs involved with retraining your network administrative personnel in recent technology.

    Because NetWare 6.5 is so tightly integrated with the IP protocol, and moreover offers backward compatibility with IPX/SPX, admins for existing NetWare networks should deem upgrading to NetWare 6.5 as well as considering other options.

    If you want to scramble to Linux, Novell makes it easy by incorporating an enhanced version of NetWare 6.5 and SuSE Linux into its Novell Open Enterprise Server. Open Enterprise Server supports both Linux and NetWare-specific software and features, enabling you to scramble to Linux gradually.

    Other LAN/WAN Protocols

    The distinction between LAN and WAN (wide belt networking) protocols is birth to blur. Ethernet was once considered to live a LAN protocol. As time has passed, other technologies, such as Token-Ring, indulge in become minor players in the LAN world. Yet the contradictory is true of Ethernet. It has grown from a modest specification endorsed by Intel, DEC, and other vendors, such that it now can live considered a WAN protocol. The capabilities introduced by current LAN technologies are birth to erode the differences between a LAN and a MAN (metropolitan belt network). When the fourth edition of this book was published, Gigabit Ethernet was starting to plunge into the inexpensive purview of network topologies. That trend has continued and now 10Gigabit Ethernet (10GbE) is frequently being used in enterprise data centers. Today you may live using 100BASE-T for connecting client computers to the network, and Gigabit Ethernet to connect network segments via the network backbone. In some cases your network might even live exclusively based on 10GbE.

    What does this move to a network administrator today? With 10Gigabit Ethernet, you can utilize TCP/IP not only to create a local belt network backbone, but to extend that gain to a metropolitan belt network. And because TCP/IP is so intertwined with Ethernet, you can achieve an end-to-end MAN link that uses TCP/IP over faster Ethernet connections. Instead of employing more expensive solutions, such as SONET, you can now connect arm offices in the selfsame geographical belt using just TCP/IP.

    You may not indulge in to worry about installing expensive rig used by SONET and other typical MAN protocols. Still, for the long haul—for example, between different cities—other protocols such as ATM and Frame Relay will Come into play.

    Verplex First With Formal Verification of Complete SoCs; Conformal Family Quickly, Exhaustively Verifies Chips With complex Logic, Memories, Custom Components | killexams.com true questions and Pass4sure dumps

    MILPITAS, Calif.--(BUSINESS WIRE)--July 28, 2003--Verplex(TM), a market leader in formal verification, today announced the release of Conformal(R) 4.0, providing a comprehensive solution that enables system-on-chip (SoC) designers and verification engineers to deliver functional bug-free silicon.

    Conformal 4.0 includes enhancements to Conformal Logic Equivalence Checker (LEC) and integrates recent Conformal family products, making Verplex the only equivalence checking company delivering a complete solution for SoC verification.

    Equivalence checking has become a standard component in an application specific integrated circuit (ASIC) design flow. Formal techniques used by equivalence checkers indulge in proven to live the best technology to exhaustively check for errors introduced by design implementation tools or manual engineering change orders (ECOs).

    Traditionally, equivalence checkers indulge in forced designers to "black box" much of their SoC, including memories, complex I/O pads, custom logic and advanced datapath. By black boxing these components, equivalence checkers only verified random logic modules, leaving the most complex and error-prone areas of the design unverified.

    Conformal 4.0 addresses these limitations institute in graphics, multi-media, digital signal processing (DSP) and communications designs, which often require advanced logic, datapath, memories and custom design modules.

    "Verplex continues to deliver breakthrough technology and they are the first to proffer a comprehensive equivalence checking solution that enables designers to verify the complete SoC," says Michael Chang, Verplex president and chief executive officer (CEO). "Formally verifying the complete SoC with their best-in-class products enables their customers to exhaustively verify the most complex portions of their designs."

    Conformal 4.0 Details

    Designs indulge in grown so complex that an independent verification, such as Conformal 4.0, is needed to audit the process by which circuitry is generated to ensure remedy results. Other formal verification tools are not independent, and may require "side files," or data clandestinely passed from implementation tools to verify these circuits. This increases the risk that formal verification uses the selfsame assumptions made during the implementation process, causing it to miss bugs introduced by implementation tools.

    Verplex's Conformal 4.0 product family continues to provide best-in-class performance and usability for the entire design stream from register transfer level (RTL) to layout. It includes five products designed to address the SoC verification challenge: Conformal LEC; Conformal Datapath (DP); Conformal Logic Transistor Extractor (LTX); Conformal remembrance (MEM); and Conformal Layout Versus RTL (LVR). sum operate within the selfsame user interface, were designed for ease of utilize and participate similar debugging approaches.

    Conformal LEC

    Conformal 4.0 enhances Verplex's flagship product -- Conformal LEC -- which performs RTL-to-gate and gate-to-gate equivalence checking. Among the enhancements are improvements in performance, ease of use, Verilog 2001 support, hierarchical comparison, design mapping and the Verplex schematic viewer.

    To address the increases in design size and complexity, Verplex continues to ameliorate performance and remembrance utilization within Conformal LEC. Users will benefit from up to 10x performance improvement for gate-to-gate comparisons and up to 5x performance improvement for RTL-to-gate comparisons. remembrance utilization was moreover improved and users will benefit from up to 30 percent less remembrance consumption.

    Conformal LEC includes numerous ease-of-use enhancements, including a schematic viewer, value annotation on the source code browser for oversight diagnosis, on-the-fly ECO editing for design validation, and automatic multiplier analysis.

    The Verplex schematic viewer improves performance by using a tightly integrated environment. This integration enables users to parade unlimited schematic sessions with a sole license and includes formal verification specific functions such as interactive prove and automatic pruning of non-controlling logic.

    Source code value annotation and tracing further improves oversight diagnosis by displaying oversight patterns on the source code and enabling the user to identify the source of the oversight by tracing drivers and loads. Expanded what-if capability enables the user to modify the design and validate the modification without leaving the Conformal environment, saving hours in debug and iteration time.

    With this release, Conformal LEC expands its language advocate to embrace advocate for Verilog 2001. This enables more efficient capture of design RTL with constructs such as multi-dimensional arrays, signed arithmetic extensions, 'generate' statement, combinational logic sensitivity, and re-entrant tasks and functions. Conformal LEC provides the most complete advocate for Verilog 2001 features used within major synthesis and simulation tools.

    Hierarchical comparison and design mapping were moreover enhanced within Conformal LEC. Hierarchical comparison is often recommended for great designs to reduce rush times and ameliorate debug when design errors are found. Capabilities were improved to embrace enhanced module border constraint generation and quick-witted module flattening.

    Conformal LEC further improves its mapping capabilities to address common naming conventions used within implementation tools and to ameliorate designer efficiency in completing this step in the process. The design-mapping step of the equivalence checking process aligns verification points between two designs being compared and these points must live consistent to achieve successful verification.

    Conformal Datapath (DP)

    Conformal 4.0 integrates recently announced Conformal DP to address requirements of high-performance SoC designs such as applications in graphics, multimedia, DSP, and communications that often utilize advanced datapath optimizations.

    Formally verifying advanced datapath has traditionally been a challenge for equivalence checking. Verplex has introduced technology capable of verifying a wide variety of datapath structures. Designers are now able to automatically verify flat datapath modules, complex merged operators, advanced pipelining techniques, and carrysave architectures.

    Conformal Logic Transistor Extractor (LTX)

    SoC designs frequently embrace custom I/O cells and designers are leveraging custom design techniques to meet performance requirements. Conformal 4.0 integrates Conformal LTX into its environment and has added improved transistor schematic and analysis capabilities that ameliorate the users' ability to efficiently compare designs.

    Conformal LTX automatically abstracts gate-level models from transistor-level circuits. This enables formal verification between the RTL model used for design simulation and the actual transistor circuit integrated prior to tapeout. It ensures that the system verification performed throughout the entire design process is sound by proving the consistency between the simulation model and actual circuit. The absent-minded models may moreover live used within other applications, including automatic test pattern generation (ATPG), simulation acceleration or emulation.

    Conformal remembrance (MEM)

    Memory typically occupies more than half of the die belt on SoC designs and trends bespeak that embedded remembrance content is increasing in terms of size and complexity. Historical remembrance verification methods involved the utilize of simulation with sum of its drawbacks such as challenging debug, degraded character of verification, and increased risk of expensive silicon re-spins due to missed bugs. The simulation approach is moreover time consuming, particularly at the transistor or SPICE level where memories are designed. Additionally, the simulation approach is incomplete, proving that designs are free from functional errors under only tested conditions, risking that bugs will slip past to final silicon.

    Verplex's Conformal MEM offers an exhaustive verification solution that addresses deficiencies of traditional approaches to remembrance verification. Through the utilize of equivalence checking, 100 percent exhaustive coverage and swiftly system-level verification are achieved.

    Conformal Layout Versus RTL (LVR)

    Conformal LVR further expands traditional equivalence checking to enable verification of the final layout. Previously, equivalence checking verified designs through the final gate-level netlist, which created a verification hollow by not ensuring that the final SPICE netlist was consistent with the golden RTL. Conformal LVR enables formal verification of the final SPICE netlist against the golden RTL or final gate-level netlist to ensure that the design taped out is functionally equivalent with golden RTL and the final gate-level netlist.

    Pricing and Availability

    The entire Conformal product family is available now. U.S. cost for a three-year, time-based license for Conformal LEC is priced from $57,600. Additional packages are available for the complete Conformal product family, which is supported on Hewlett Packard HP-Unix(TM), Sun Microsystems Solaris(TM), IBM AIX(TM), and Linux operating systems platforms.
