Page 1 Chapter 11 Instructor's Manual ______________________________________________________________________________ Chapter Objectives Chapter 11, Network Organization and Architecture, focuses on network organization and architecture, including network components and protocols. The OSI model and TCP/IP suite are introduced in the context of the Internet. This chapter is by no means intended to be comprehensive. The main objective is to put computer architecture in the correct context relative to network architecture. Lectures should focus on the following points: History of networks. A brief introduction into the roots and architecture of the Internet helps students to understand the current state of networking. Network protocols . Understanding network protocols is key in understanding how networks work. The deli parable is an excellent example to explain networking protocols in non-networking terms. Lecture can then focus on the OSI 7-layer model. TCP/IP architecture. IPv4 and IPv6 are the two versions of the Internet Protocol in use today. Understanding IP and TCP and their requirements is critical in understanding most Internet applications, which rely on these two protocols. Network organization. The physical network components (such as the transmission media, interface cards, repeaters, switches, hubs, bridges, gateways, and routers) are important as they must be chosen with consideration to the anticipated load and distance to be covered. Digital links. The physical components of a network must be connected, and there are many ways in which this can be achieved. In addition to FDM, PCM, TDM and PDH, ISDN and ATM are discussed. Although the public switched telephone network continues to be the Internet &quot;on ramp&quot; for most homes and small businesses, ISDn and DSL are offering some relief to overcrowded analog circuits. However, routing problems and congestion may require revamping the basic architecture that forms the foundation for the Internet. A look at the Internet. Traditional dialups and modems and DSL are the most common methods of ramping on to the Internet....
