  • System and method for realizing the resource distribution in the communication network
    Patent number: 7636781
    Abstract: The present invention relates to a system for implementing resource allocation in network communication and a method thereof. It effectively solves the end-to-end QOS problem through dividing a communication network into a plurality of QOS domains and managing them. In the present invention, only end-to-end path information is maintained at the QER of the QOS domain that is directly connected with the source/destination terminal, while only edge-to-edge resource reservation information for aggregate flows is maintained at other QERs, thus significantly reducing flow state information maintained at the network nodes as well as overhead of signaling protocol processing and storage at the network nodes.
    Type: Grant
