An Efficient Adaptation of RSVP-TE in GMPLS

RSVP is extended to RSVP-TE to support LSP establishment in MPLS. SInce the original RSVP is the signaling protocol for IntServ QoS model, its receiver-initiated resource reservation has low performance in MPLS, especially in the lightpath setup on optical networks via GMPLS. Based on the optical networks in MPLS, this paper proposes a new adaptation of RSVP-TE. Both performance analyses and experiment results show this new scheme is superior to the original approach and the larger the network size is, the better the performance is.
