Abstract: A method and related apparatus for providing latency optimized segment routing tunnels is described herein and includes obtaining a latency metric for each segment that links respective pairs of nodes in a network, determining a tunnel through the network between a first endpoint and a second endpoint that is optimized for latency, and, once such a tunnel is determined, causing a packet to travel along the tunnel that is optimized for latency by encoding the packet with segment routing instructions for the network, wherein the network is configured to provide shortest paths according to a metric other than latency.
