Abstract:
Systems and methods provide for segment routing (SR) with fast reroute in a container network. An SR ingress can receive a packet from a first container destined for a container service. The ingress can generate an SR packet including a segment list comprising a first segment to a first container service host, a second segment to a second service host, and a third segment to the service. The ingress can forward the SR packet to a first SR egress corresponding to the first host using the first segment. The first egress can determine whether the first service and/or host is reachable. If so, the first egress can forward the SR packet to the first host or the packet to the service. If not, the first egress can perform a fast reroute and forward the SR packet to a second SR egress corresponding to the second host using the second segment.
