Aggregated resource reservation protocol in integrated scalable-terrestrial and Int-Serv satellite network

This paper focuses on a recently proposed Diff-Serv like architecture called scalable core (SCORE). This one is used in the terrestrial network in order to offer more scalability and deterministic guaranteed services. The integration issues between a scalable terrestrial and a satellite network based on Int-Serv architecture are outlined. The Aggregated RSVP protocol on integrated scalable terrestrial and IntServ satellite network has been introduced in order to guarantee the interoperation between the SCORE architecture and the satellite segment. The system performance in terms of signalling overhead and resource utilization has been set out. The study shows that increasing aggregated bandwidth reservation can improve signalling but can under utilize the terrestrial channel. The satellite network, instead, can improve its static efficiency due to the increased number of calls accepted on the satellite link.
