Cisco Public 2 Cisco Thai Nguyen Networking Academy Frame Relay An Efficient and Flexible WAN Technology Frame Relay has become the most widely used WAN technology in the world. -Large enterprises ISPs and small businesses use Frame Relay because of its price and flexibility. Case study Example of a large enterprise network. -Chicago to New York requires a speed of 256 kb s. -Three other sites need a maximum speed of 48 kb s connecting to the Chicago headquarters -The connection between the New York and Dallas branch offices requires only 12 kb s. Using leased lines -The Chicago and New York sites each use a dedicated T1 line equivalent to 24 DS0 channels to connect to the switch while other sites use ISDN connections 56 kb s . -Because the Dallas site connects with both New York and Chicago it has two locally leased lines. -These lines are truly dedicated in that the network provider reserves that line for Span s own use.
