Abstract:
1. A method performed by an ingress node for negotiating a flow label (FL) processing capability, comprising: constructing a resource reservation protocol-traffic engineering (RSVP-TE) path message, wherein the RSVP-TE path message comprises a first FL capability flag bit indicating whether the ingress node is configured to process an FL carried in a packet received from an egress node; sending the RSVP-TE path message to the egress node; receiving an RSVP-TE resv message in response to the RSVP-TE path message, wherein the RSVP-TE resv message comprises a second FL capability flag bit indicating whether the egress node is configured to process an FL carried in a packet generated by the ingress node; obtaining, from the second FL capability flag bit an indication whether the egress node can process the FL carried in the packet received from the ingress node.
