Abstract
A method and arrangement in a communications network. The object 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 combing the routing information and resource information, and performing recourse management issues and admission control within the system by the resource map and by interacting with a gatekeeper.
Claims29
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 resource management issues and admission control within the system (400) by means of said resource map and by interacting with the gatekeeper (Gk),
- wherein the IP network is routed using a distance vector protocol, or static routing, the resource manager (RM) comprises means for using measurements such as trace route and/or the Simple Network Management Protocol (SNMP) auto discovery to retrieve routing information of the IP network.
A method for handling performing resource management issues and admission control within an Internet Protocol IP telephony system (400) adapted for transmission of multimedia over an IP network, the system (400) comprising a topology aware resource manager (RM);
- characterised in that the method comprises the following steps to be performed by the resource manager (RM):
- 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;
- via the gatekeeper (Gk) performing path-sensitive resource management issues and admission control within the system (400) by means of said resource map and by interacting with a gatekeeper (Gk),
- wherein the IP network is routed using a distance vector protocol, the method comprising the further step of:
- the resource manager (RM) using measurements such as trace route and/or the Simple Network Management Protocol (SNMP) auto discovery to retrieve routing information of the IP network.
