Abstract

The invention relates to a network measuring technology, and discloses a method, device and system for measuring the network performance between the Overlay nodes. The method in the invention comprises: seeking a source network node corresponding to the Overlay source node and a target network node corresponding to the Overlay target node respectively; seeking a converging node corresponding to the source network node and the target network node respectively; sub-measuring the network performance of that between the source network node and the corresponding converging node, between two converging nodes and between the target network node and the corresponding converging node, and computing the network performance between the Overlay nodes according to the measuring result. The system in the invention comprises a network measuring unit and a measuring unit, which are used to finish the measurement of the network performance between the Overlay nodes.

Description

technical field

[0001] The present invention relates to measurement technology in the field of communication network, in particular to a method, device and system for measuring network performance between Overlay nodes. Background technique

[0002] The overlay network (Overlay network) is a network topology organization working at the application layer, and completes specific services by constructing a network topology between application layer nodes. Typical Overlay network applications include content delivery network (Content Delivery Network, CDN), peer-to-peer network (peer-to-peer network, P2P), application layer multicast, and so on.

[0003] The Overlay network uses the interconnection of application layer nodes to build the network. In the process of building the Overlay network, in order to reduce the route detours in the network, it is necessary to check the distance, delay, bandwidth and other performance of each node on the Overlay network and the performance o...
