Abstract
For providing high quality-guaranteed service over Internet, traffic engineering based on an MPLS technology is being introduced. MPLS traffic engineering performs the computation on the path guaranteeing service`s quality and the reservation on network resources by an MPLS signaling protocol. As one of MPLS signaling protocol, RSVP-TE protocol transmits and receives periodic refresh messages for maintaining the path of a traffic flow. Such characteristic gives a heavy processing overhead to routers for maintaining states of large number of paths. In this paper, we propose a scalable implementation approach for RSVP-TE without dramatically increasing processing overhead. And we eval-uate the processing overhead on periodic messages by implementing the RSVP-TE protocol and the reduction mechanism of periodic messages.
