FRAME RELAY TO ATM INTERWORKING

Frame Relay is a well-established technology that has attracted a larg e number of customers world-wide. It is typically used to interconnect large, multi-site company local area networks (LANs). These data conn ections are usually at low to medium speeds. Asynchronous transfer mod e (ATM) is a newer broadband technology that is capable of very high s peed LAN interconnection. In addition, it is arguably an ideal transpo rt medium for legacy protocols such as Frame Relay. This paper describ es the data transport features of each technology and discusses how AT M may be used to interconnect existing Frame Relay networks, and how a n ATM user may exchange data with a Frame Relay user.
