MPLS망에서의 확장성을 갖는 RSVP-TE 프로토콜 현을 위한 메시지 부하의 영향 분석

Abstract

For providing high quality-guaranteed services 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 protocols, 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 evaluate the processing overhead on periodic messages by implementing the RSVP-TE protocol and the reduction mechanism of periodic messages.
