Description
As customers migrate en masse from private lines to frame relay/ATM technologies, the need for effective multi-protocol wide-area networks increases dramatically. With this new book, network designers and engineers get the help they need to ensure that hardware, software, and data transport devices deliver the expected level of performance in this challenging environment.
