- Abstract
- As quality-guaranteed services, such as voice and streaming services, are required over Internet, traffic engineering based on an MPLS technology is being introduced. In MPLS traffic engineering, information related with service's quality requirements is forwarded through routers on a quality-guaranteed path by an MPLS signaling protocol. Routers on the quality-guaranteed path forward traffic for the specific service under the control by its predefined quality requirements. As one of MPLS signaling protocols, RSVP-TE protocol transmits and processes periodic protocol messages for maintaining the soft state of a quality-guaranteed path. Such characteristic gives a heavy processing overhead to routers for maintaining states of large number of paths. In this paper, we implement a scalable and load-efficient 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
