Segment Routing (SR) Policy Candidate Paths Segment Routing (SR) Policy Candidate Paths
Abstract Abstract
A Segment Routing (SR) Policy is an ordered list of instructions A Segment Routing (SR) Policy is an ordered list of instructions
called "segments" that represent a source-routed policy. Packet called "segments" that represent a source-routed policy. Packet
flows are steered into an SR Policy on a node where it is flows are steered into an SR Policy on a node where it is
instantiated. An SR Policy is made of one or more Candidate Paths. instantiated. An SR Policy is made of one or more Candidate Paths.
