Implementation of RSVP Protocol in Quagga Software

Abstract

Multimedia applications are already most popular on the Internet, and they are much better served with bandwidth and delay guarantees. Providing support for multimedia applications over the Internet is a difficult task because they require more bandwidth than standard applications. Aside from that, multimedia applications are real time so it is essential to guarantee certain capacity. RSVP protocol provides the basic quality of service on the Internet such as bandwidth reservations. This paper presents implementation of RSVP protocol that supports basic functionalities in Quagga Routing Suite software. Our implementation is meant to serve as a base for adding new functionalities. We have used modern concept of virtualization to provide environment for testing. In this paper, we present implementation and routing of Resv messages. Resv messages are routed based on IP lookup that uses the longest prefix matching. We validated our RSVP implementation through its testing in virtual environment. Guidelines for future improvements and upgrades to RSVP-TE protocol are recommended.
