Platform for Capacity Reservation in IP Networks

Abstract

The fast development of multimedia devices and services causes the need for increase of the transport capacity of packet networks. OSPF-TE uses both the information about network topology and the link utilization when finding the routing path. Accordingly, it might find path even in the cases when the shortest path routing would cause overloaded link and dropped packets. In this paper we develop the platform for capacity reservation in IP networks. We implement OSPF-TE protocol as an extension of the existing OSPF. In addition, the basic functionalities of the reservation protocol and the user interface are implemented. We present the simulation environment for the verification of our implementation and for the analysis of various routing algorithms based on the information conveyed by OSPF-TE.
