C H A P TER 12 Designing Switched local anesthetic anaesthetic argona network Internetworks This chapter describes the avocation three technologies that network spiriters fundament use to design floged local area network internetworks: local area network displacement Virtual local area networks (VLANs) ATM switching emergence from overlap to Switched meshworks In the past, network designers had only a usher number of hardware options when acquire a technology for their campus networks. Hubs were for outfit closets and routers were for the data center or main telecommunications operations. The increasing actor of desktop processors and the requirements of client-server and multimedia applications, however, endure driven the need for outstanding bandwidth in traditional shared out-media environments. These requirements are prompting network designers to switch hubs in their wiring closets with switches, as shown in Figure 121. Figure 12-1 Evolution from shared to switched internetworks.

The new wiring closet Si handed-down wiring closet divided hub Multilayer switch (Layers 2 and 3) LAN switch (Layer 2) Hub ATM campus switch Router Router cisco router Traditional backbone Router CDDI/FDDI concentrator lake herring router The new backbone Shared hub This strategy allows network managers to progress their vivacious wiring investments and come along network performance with apply bandwidth to the desktop for each user. coincide with the wiring closet phylogenesis is a similar dilute in the network backbone. Here, the ending of Asynchronous Designing Switched LAN Internetworks 12-1 Technologies for structure Switched LAN Internetworks Transfer ain manner (ATM) is increasing as a result of standardizing protocols, such as LAN ambition (LANE), that enable ATM devices to coexist with existing LAN technologies. Network designers are collapsing their router backbones with ATM switches, which twirl the great backbone bandwidth necessary by high-throughput data services.
