Distributed exterior gateway protocol

摘要

A border gateway has a control card and at least one line card. The control card has a control processor to execute a control portion of an exterior gateway protocol and a routing table of exterior gateway routes and devices. The line card has a line processor to execute an offload portion of an exterior gateway protocol and a communications port to allow termination of at least one communication link. A backplane allows the control card and the line card to communicate.
