Abstract Abstract
Segment Routing (SR) allows a headend node to steer a packet flow Segment Routing (SR) allows a headend node to steer a packet flow
along any path using a segment list which is referred to as a SR along any path using a segment list which is referred to as a SR
Policy. Intermediate per-flow states are eliminated thanks to source Policy. Intermediate per-flow states are eliminated thanks to source
routing. The header of a packet steered in an SR Policy is augmented routing. The header of a packet steered in an SR Policy is augmented
with the ordered list of segments associated with that SR Policy. with the ordered list of segments associated with that SR Policy.
