Normally, the course will have been installed for you, and all you will have to do is start it up. First turn on your computer. Make sure you know which drive the course is installed on. (The course administrator or whoever is in charge of the installation should be able to tell you. It is normally installed on the C: drive or on your LAN.) Run windows, open the appropriate CBT group and then select the course. All you have to do now is follow the instructions on screen. If the Student Registration system is in place Type your user-number. This will be supplied by whoever is administering the course. You may also be asked to type a password. This will be supplied by your course administrator. If the Student Registration system is not in place Type 0 when you are asked for your user-number. This will take you straight to the main menu screen. If the Self Registration system is in place If you have not been allocated a user-number, type self. You will then be prompted to enter your name and whatever number you choose. Your user-number will then be created for you, and any time you re-enter the course, you should enter this user-number. Main menu/course map When you first enter the course, you will be presented with the course map, which also functions as the course menu, with course units listed. To see the topics menu for any unit, click that unit. To see the topics menu for another unit, there is no need to close the current topics menu: simply click the relevant unit in the list of course units to replace the current topics list with the required topics list. Double-click any topic to enter the unit at the start of that topic. Double-click any screen number to enter the unit at the start of that particular screen.

In this case, your score so far will be discounted Questions and Tasks As you work through the course, you will find that presentation of material is constantly tempered by questions. Some questions are asked in order to check that you have understood a point you learned earlier in the course. But more often, you are asked discovery questions. These are questions that you may not know the answers to. This is part of our teaching technique and is a strategy for drawing you into active participation in your own learning. Discovery questions are there not to test you but to provide you with the opportunity to enter into dialog with the course. They are asked in a spirit of involvement, nudging you towards conclusions, helping you to make connections. Instead of being a passive recipient of snippets of narrative, you are asked to take an active part, attempting to work out for yourself how you think the narrative will unfold. For this reason, you should not feel intimidated by these questions, or feel that you should be able to answer them all. If you answer a question incorrectly, that is not a mark of failure; look on it simply as an opportunity to learn the right answer. In addition, the course may include simulations, where you are invited to practice using the application by completing a series of tasks. If you complete a task correctly, you will not normally be given feedback, but your action will simply have the result it would have in a real application environment. If you do not complete the task successfully, you will either be invited to try again, or the task will be completed for you. Taking the Test The test is presented in two formats: you can take a course test, where you are tested on the contents of the whole course; or there may also be individual unit tests. We recommend that you should follow the course and then take the course test. The test results indicate which units if any you need to review. We suggest that you should review the recommended units, and then take the appropriate unit tests (if available). You could also repeat the full course test if you wish. The course test can also be used as a pre-course test. If you feel you are reasonably proficient in the course material, you could test your skills by taking the course test before you follow the course. The results may indicate that you should take the whole course, or that you should concentrate on particular units. Again, if you decide to concentrate on particular units, you can test your knowledge of these units afterwards by taking the unit test. In any case, it is not recommended that you follow a unit and then take the unit test immediately. It is better to allow a time lapse, and perhaps to take a group of unit tests together. To take the test, click the option button Test at the foot of the Course Map screen. You will be presented with a menu, from where you can choose the test you require. The first option on this menu is Full Course Test. If you choose this option, you will be taken into a test consisting of a large number of randomly generated questions ranging over the content of the whole course. Because the questions are randomly generated, you may take the full course test more than once without being presented with the same selection of questions. Alternatively, you may choose to be tested on any individual unit, simply by selecting that unit from the test menu. Note that the questions in the unit-based tests are not randomly generated, so if you repeat any unit test, you will be asked the same series of questions. Although the questions in the test look much like questions in the course, it is important to realize that they serve a different function - that of assessing your assimilation of material covered in the course. For this reason, questions in the test are more strictly judged than questions in the course. You will not have the option to skip questions (ie the Cancel button will not be active) and you will not normally have a second chance to attempt a question after feedback has been given. At the end of the test you will be given your results, and it will be indicated to you which units of the course you need to review, if any. It is especially important to type answers carefully in the test. The test is not designed to accept as wide a range of spelling errors as the course. Your score is electronically recorded via the CMI (computer managed instruction) system. If you take the course test, and subsequently take individual unit tests, your score in the unit test will over-ride your score in the same units in the course test. If you take the course test again, your latest course-test score will over-ride any other tests you may have taken earlier. Your test score is accessible to the course administrator and you can also check it yourself at any point from the main menu screen. Simply click on the Progress button (or press Alt+ p) at the foot of the main menu screen.

Course Guide Units in Internetworking Overview Introducing internetworking The OSI model Common technologies - topologies Common technologies - protocols Routing basics Routing algorithms Introducing internetworking Topics Evolution of internetworks Global internetworking Devices for LANs and WANs Unit aim To introduce internetworking Unit objectives After completing this unit you should be able to q outline the evolution of internetworks q outline the demands of a global internetwork q list and briefly describe the devices you would find on a LAN q list and briefly describe the devices you would find on a WAN Unit summary Internetworks have evolved in response to changing demands and new technologies. Internetworks tie LANs and WANs, computer systems, software, and related devices together to form the corporate communications infrastructure. Today's network users demand high bandwidth, low delays, and multimedia capabilities from global internetworks. The global internetwork must be reliable, easily managed, and be able to connect many disparate networks. LANs connect computers within a limited geographical area. WANs use the services of telecommunications carriers to operate beyond the LAN's geographic scope. Devices you would find on both LANs and WANs include q routers q ATM switches Devices you would find specifically on a LAN include q repeaters q bridges q hubs q Ethernet switches q gateways Devices you would find specifically on a WAN include q X.25 or Frame Relay switches q modems, CSU/DSU devices, TA/NT1 devices q communications servers q multiplexors Users Notes The OSI model Topics The layered OSI model Physical layer and data-link sublayers The network layer OSI upper layers Unit aim To describe the OSI reference model Unit objectives After completing this unit you should be able to q outline the origin of the OSI reference model q list the seven layers of the OSI reference model q explain the benefits of a layered approach q describe peer-to-peer communication q describe data encapsulation q outline the functions of the physical layer of the OSI model q outline the functions of the data- link layer of the OSI model q briefly describe the two sublayers of the data-link layer q outline the functions of the network layer of the OSI model q describe path determination q outline the functions of the transport, session, presentation, and application layers of the OSI model Unit summary The OSI reference model is made up of seven layers: q the application layer q the presentation layer q the session layer q the transport layer q the network layer q the data-link layer q the physical layer Layers in one system communicate with their peer layers in other systems. The information to be sent descends through the layers of the sending system and is encapsulated with headers and trailers from each layer as appropriate. At the physical layer it is transformed into electrical signals and sent over the physical medium. At the other end it ascends through the other system's layers and the headers and trailers are stripped off until the message reaches the second application. (contd on page 20) Users Notes The physical layer of the OSI model defines the physical and functional specifications for activating, maintaining, and deactivating the physical link between end systems. The data-link layer of the OSI model is responsible for providing reliable transit of data across a physical link. The data-link layer is divided into two sublayers: q the logical link control (LLC) sublayer q the media access control (MAC) sublayer Layer three of the OSI model, the network layer, is responsible for providing consistent end-to-end packet delivery services to the transport layer. Routers determine an optimal path to a destination using routing algorithms and routing tables. The transport layer of the OSI model provides mechanisms for q multiplexing upper layer applications q the establishment, maintenance, and orderly termination of virtual circuits q information flow control q transport fault detection and recovery The main function of the session layer is to control data conversations between devices. These are known as "sessions". The presentation layer is concerned with q the format and representation of user data q the data structure (or syntax) used by programs q data encryption q standards for image and sound formats The application layer q identifies and establishes the availability of the intended communication partner q synchronizes the sending and receiving applications q establishes agreement on procedures for error recovery and control of data integrity q determines whether sufficient resources for the intended communications exist Users Notes Common technologies - topologies Topics Ethernet and Token Ring FDDI and ATM Unit aim To describe some common topologies Unit objectives After completing this unit you should be able to q outline the basic characteristics of Ethernet and Token Ring networks q outline the basic characteristics of FDDI and ATM Unit summary Ethernet is a very common LAN technology. It provides data transport across the physical link joining devices on a LAN. The Ethernet specification describes a carrier sense multiple access with collision detection (CSMA/CD) LAN. After Ethernet, the next most popular LAN specification is Token Ring. Token Ring networks operate by passing a small frame, called a token, around the network. Although logically a ring, the Token Ring network is physically laid out as a star. Whereas Ethernet broadcast media provides opportunistic access, Token Ring provides fair deterministic access. FDDI provides a very reliable network environment which operates over dual counter-rotating rings. It was developed for high speed, high bandwidth requirements. FDDI operates at 100 Mbps over optical fiber medium. ATM is a high speed, high bandwidth cell relay technology It can support demanding applications such as q interactive multimedia q real-time video services q client/server databases q interconnection of existing networks Users Notes Common technologies - protocols Topics Serial data,X.25, and Frame Relay TCP/IP protocols Novell IPX/SPX AppleTalk, Banyan VINES, DECnet Unit aim To describe some common LAN and WAN protocols Unit objectives After completing this unit you should be able to q outline the basic characteristics of Serial data,X.25, and Frame Relay q briefly describe the TCP/IP suite of protocols q briefly describe the Novell IPX/SPX protocols q outline the basic characteristics of AppleTalk, Banyan VINES, and DECnet Unit summary The WAN physical layer describes the interface between the data terminal equipment (DTE) and the data circuit-terminating equipment (DCE). WAN data-link protocols such as Frame Relay and X.25 describe how frames are carried between systems on a single data link. The common data-link encapsulations associated with synchronous serial lines are q Synchronous Data Link Control (SDLC) q Point-to-Point (PPP) q High-Level Data Link Control (HDLC) q Link Access Protocol, Balanced (LAPB) X.25 provides a synchronous, bit-serial full-duplex point-to-point circuit for data transmission between the DTE and the DCE. X.25 defines three basic types of packet service: q a switched virtual circuit q a permanent virtual circuit q a connectionless, datagram service (contd on page 26) Users Notes Frame Relay was developed to meet the needs of bursty data traffic. It is a service designed to exploit the high quality and high bandwidths offered by optical fiber links. TCP/IP is a suite of protocols incorporating protocols at the network, transport, and application layers of the OSI model. IP and TCP are the most important of these. IP provides connectionless, best-effort delivery routing of datagrams and TCP guarantees packet delivery and data integrity. Two main protocols in Novell's NetWare are IPX and SPX. IPX is a network layer protocol that provides a very fast connectionless service. It provides network layer services such as addressing and routing. SPX is a transport layer protocol. It is a connection-oriented protocol, providing error checking and windowed flow control. It ensures reliable delivery by retransmitting information that has not been correctly received. AppleTalk is a suite of networking protocols for the Apple Macintosh. It works with Apple's own lower-layer protocol, LocalTalk, but can also run over the standard lower-layer protocols such as Ethernet and Token Ring. Banyan Virtual Integrated Network Service (VINES) implements a distributed network operating system. It provides three transport layer services: q unreliable datagram service q reliable message service q data stream service DECnet is described by the DNA architecture. DNA is fully OSI-compliant and supports a wide variety of protocols. Users Notes Routing basics Topics Routing components Addressing Classful and classless addressing Design goals Routed v. routing protocols Unit aim To introduce the basics of routing Unit objectives After completing this unit you should be able to q explain what a router is q describe the two basic activities of routers, path determination and switching q briefly describe the different metrics used by routing algorithms q outline the addressing schemes used by various protocols q briefly describe IP addressing q outline the different design goals for routing algorithms q explain the difference between routed and routing protocols Unit summary A router is a device that routes packets across an internetwork. It makes decisions about the route to a packet's destination and it relays it from one data link to another. Path determination enables the router to evaluate available paths to a destination and determine which to use. Routers determine the path to a destination using routing algorithms, which initialize and maintain routing tables containing route information. The switching function of a router allows it to accept packets on one interface and forward them to a second interface. Routing algorithms use one or more of the following metrics: q path length q reliability q delay q bandwidth q load q communication cost Node addresses and network addresses should be unique in order to avoid conflicts on an internetwork. (contd on page 30) Users Notes Many protocols use a two-part addressing scheme. The first part of the address identifies the network and the second part the node. How the address parts are interpreted and what authority allocates them differs from one protocol to another. Routing algorithms often have one or more of the following goals: q optimality q simplicity q robustness q rapid convergence q flexibility In classless addressing the prefix can be of any length. The length of the prefix is indicated either by a network mask or by a number following the address. In classful addressing only a few specified prefix lengths are allowed, possibly extended by subnet masks. In standard IP classful addressing q class A has a prefix length of 8 bits and starts with 0 q class B has a prefix length of 16 bits and starts with 10 q class C has a prefix length of 24 bits and starts with 110 The particular design goals of the algorithm affect the operation of the resulting routing protocol. Routed protocols are protocols that are routed over an internetwork. They carry trafic accross the network. Routing protocols are protocols that implement routing algorithms in order to allow routers to direct routed protocol packets. Users Notes Routing algorithms Topics Static and dynamic routing Integrated routing protocols Unit aim To describe the different types of routing algorithm Unit objectives After completing this unit you should be able to q describe static and dynamic routing q briefly describe distance vector and link state routing algorithms q describe the features of integrated routing protocols Unit summary Static routing is administered manually. A network administrator enters the route information into the router and must manually update it whenever there is a change in the topology of the network. Dynamic routing algorithms automatically adjust in real time. Whenever there is a change in the topology of the network they send out update messages to the other routers. Each router then re-runs its routing algorithm and adjusts its routing table. Distance vector routing algorithms determine the direction and distance to any link in the internetwork. Each router periodically sends all, or a portion of, its routing table to its nearest neighbors only. Link state routing algorithms maintain a complex database of topology information. Each router sends only that portion of the routing table that describes the state of its own links. Balanced hybrid routing algorithms are a combination of the best of both. They use distance vectors to determine the best paths to destination networks, but allow network topology changes to trigger the routing updates. Like link state routing algorithms they converge rapidly. However they have a lower CPU, bandwidth, and memory overhead. Users Notes Installation Procedure To install the course First run Windows. Then insert disk 1 in the A or B drive, as appropriate. From the Program Manager, choose File - Run. Next either q type a:setup (or b:setup, as appropriate) and press Enter or q use the Browse option and select your floppy disk drive and then setup.exe You will then be given the option to change the drive on which the course is to be installed. When you are happy with the options here, click Continue. Next, you will be asked to specify where you wish to install the Windows resource files which the course needs. You may choose to install these in the course directory or in your Windows SYSTEM directory. If installing on a network, read Considerations for network use on the next page before installing. You will be prompted to insert further disks as required. To remove the course Run Windows. Insert the course disk 1 in drive A or B, as appropriate. From the Program Manager, choose File - Run. Next either q type a:remove (or b:remove, as appropriate) and press Enter or q use the Browse option and select your floppy drive and then remove.exe You will then be asked to select the drive where Internetworking Overview is installed. If you choose Continue, and if the course is on the selected drive, the course will be deleted and the subdirectory removed. Considerations for network use There are a number of Windows resource files which the course needs in order to run. During installation, you are given the choice of installing these in either the course directory or the Windows SYSTEM directory. If you are installing the course on a LAN drive, it is best to put these files in the course directory, so that they will be accessible to other workstations on the network. Access from other workstations To access the course from a workstation other than the one used to install the course, follow these steps: Load Windows. Either create a program group for CBT Cisco courses, or open this group if it already exists on the workstation. Choose File - New - Program Item. Using the Browse option, select the file CISCO1.EXE in the course directory on the network drive where you installed the course. Click OK when satisfied with the options. There will now be an icon for the course on your Windows desktop. Double-clicking on this icon will run the course. Computer Managed Instruction Administration The course is administered via a CMI (Computer Managed Instruction) system. Normally, only the course administrator has access to the CMI system. How to install the CMI Administration system It's best to install the CMI Administration system on the course administrator's PC. But remember, the CMI system must be able to access the course - if the course is not on a LAN, you must install the CMI system and the course on the same PC. First run Windows (version 3.1 or later required). Insert the CBT Curriculum - CMI Admin Disk in drive A or B, as appropriate. From the Program Manager, choose File - Run. Next either type a:setup or b:setup (as appropriate), and press Enter or use the Browse option to select your floppy disk drive and then type setup.exe You are now given the option of changing your CMI system installation drive. When you're ready, click Continue. The CMI Administration system is now installed on your selected drive, and a program group called "CBT Systems CMI Administration" is created. This group contains the program icon. If you want, you can move this icon to another group. How to enter the CMI Administration system Run Windows and select the CMI Administration icon from the appropriate group. On entering the program, you will be asked to enter your CMI password. If this is the first time the program is being run, enter a new password - this will then become the CMI password. If the program has been run before, you must enter the existing CMI password. If you want to change the existing password, click the New button. You must then enter the existing password, before entering your choice for the new password. The CMI password is not case-sensitive.
