Abstract:
1. A method for controlling traffic flow in a telecommunication network including a plurality of network nodes, each network node having a temporary different capacity limitation for handling signalling multimedia sessions over data networks, the method comprising the steps of: (a) negotiating between two network nodes whether a mechanism exist in both nodes for controlling the traffic flow between said nodes in both directions, from a traffic sender node to a traffic receiver node; (b) determining the capacity limitation of at least one traffic receiver node; and (c) accommodating the traffic load between the traffic sender node and the traffic receiver node to the capacity limitation of the traffic receiver node; (d) negotiating between said two network nodes whether a capacity reference exchange (CRE) mechanism exist in both nodes for establishing maximum reference limits for the traffic flow between them in both directions, said negotiation being initiated at any one of said nodes; (e) using a CRE mechanism for establishing a maximum reference limit for the traffic flow between said nodes in at least one direction of the traffic flow, including the following steps:
