Applications: Asynchronous Transfer Mode and Synchronous Optical Network

摘要: This chapter illustrates the fundamental characteristics of telecommunications and data networks resulting requirements on integrated services networks. Integration these two applications initially started in wide-area networks, where economic considerations dictated that use existing telephony infrastructures. However, increasing digital media types promises integration can reach both corporate office home or consumer future. Asynchronous transfer mode (ATM) refers to an enabling network technology supports broadband-integrated services. ATM essentially defines a common layer interoperability called layer, which various ranging from video conferencing TCP/IP networking multimedia be delivered. The format used for switching multiplexing bit streams one end another. implemented variety physical layers. It also different traffic classes by providing adaptation layers higher levels.
