摘要:
According to one aspect, a method includes obtaining a segment routing (SR) packet from an endpoint via a first router at a first server along a path, the SR packet including an SR list and a last address, the last address being an address of a requested service. The method also includes determining, at the first server, whether the requested service is available from the first server, wherein determining whether the requested service is available from the first server includes opening the SR packet, parsing an SR header of the SR packet, and performing a lookup in a service table. Finally, the method includes modifying the SR packet at the first server when it is determined that the requested service is not available from the first server; and forwarding the SR packet along the path.
