Method for, and a topology aware resource manager in an ip-telephony system
First Claim
1. A topology aware resource manager (RM) within an Internet Protocol IP telephony system (400) for transmission of multimedia over an IP network, the system comprising a gatekeeper (Gk), wherein the resource manager (RM) comprises:
- means for collecting routing information concerning the IP network;
means for obtaining resource information concerning resources within the IP network;
means for creating a resource map by means of combing said routing information and resource information;
characterised in that the resource manager (RM) comprises;
means for via the gatekeeper (Gk) performing path sensitive recourse management issues and admission control within the system (400) by means of said resource map and by interacting with the gatekeeper (Gk).

Abstract
The present invention relates to a method and arrangement in a communications network. The object of the present invention is to provide a way of handling recourse management issues and admission control within an IP telephony system. The object is achieved by a topology aware resource manager collecting routing information concerning the IP network, obtaining resource information concerning resources within the IP network, creating a resource map by means of combing said routing information and resource information, and performing recourse management issues and admission control within the system by means of said resource map and by interacting with a gatekeeper.
