Abstract
A controller, including a processor and a non-transitory computer-readable storage medium storing a program to be executed by the processor for managing a first autonomous system (AS), the program including instructions to receive a first Border Gateway Protocol (BGP) routing message, determine a destination node, the destination node belonging to the first AS, determine, according to a node that sends the first BGP routing message, whether to perform incoming-traffic adjustment and control, allocate a source node from a second AS directly connected to the first AS, obtain a preferred path between the source and destination nodes according to a network topology, determine a first BR and a second BR on the preferred path, and send a routing control message to a specified BR belonging to the first AS instructing the specified BR to use the first BR as a next hop for packet forwarding of the second BR.
