ROUTING CONTROL METHOD USING QUALITY OF SERVICE(QOS) PARAMETER IN ROUTING REGISTRY SPEC

摘要

PURPOSE: A routing control method using a quality of a QoS parameter in a routing registry spec is provided to support an optimum network design in consideration of a performance of a network and effectively use a network resource by defining and registering information related to the performance of a network in a routing registry and performing a routing by using the network performance value. CONSTITUTION: A network operator inquires the optimum path using a specific QoS parameter value for a target network(A1), it is determined whether there are a plurality of paths to a destination(A2). If a plurality of paths do not exist, a path is constructed by using only connection information(A3). If there exist a plurality of paths, it is determined whether there is the minimum delay value in the QoS parameter values stored in the routing registry, and if there is the minimum value, a path having the value is constructed(A4). If there is no minimum delay value, it is determined whether the maximum throughput value, and if there exists a throughput value, a path having the value is constructed(A5). If there is no maximum throughput value, a path is constructed by using only the connection information(A3). When the paths are completely constructed, a routing path response is made for the target network(A6).
