Title: NETWORK PERFORMANCE MEASUREMENT METHOD AND DEVICE
Abstract:
Provided are a network performance measurement method and device. The method comprises: determining a measurement path set according to a performance measurement target, network topological information and measurement performance information about a node in a network, wherein the measurement path set comprises at least one path to be measured in the network, and each path to be measured passes through at least one link in the network; respectively sending a measurement application message to a start node and an end node of the path to be measured in the measurement path set; and receiving a performance measurement result sent by the start node or the end node, and determining the link performance of a link in the network according to the received performance measurement result. In the method, all pieces of link performance data in a network are obtained by means of partial measurement, so that the computing complexity is reduced and the network overhead is reduced.
