Problems solved by technology

On the edge network, due to limited bandwidth and other resources, for example, end users widely use Internet access methods such as DSL and Cable, resulting in performance bottlenecks in the last hop.
In addition, the egress bandwidth between different ISP networks is usually limited, which is prone to performance bottlenecks

Abstract

The invention discloses a large-scale network link performance measurement method and system based on SNMP. According to a monitoring target issued by a control subsystem, SNMP performance statisticalinformation of a specific router is monitored by using a multi-thread technology, and performance information of a corresponding interface is obtained through calculation, including an input/output bandwidth utilization rate interface operation state of the interface. Each probe is responsible for monitoring the performance of a plurality of router interfaces according to a customized strategy, and periodically collects the performance information of a specified link in a network. The method is simple to operate, has less invasion to the network, is convenient to realize automation, and has the advantages of being scientific, objective, simple and feasible.

Description

technical field [0001] The invention relates to an SNMP-based large-scale network link performance measurement method and system, belonging to the technical field of network data communication. Background technique [0002] The available bandwidth of the end-to-end path of the Internet has an important impact on the performance of distributed applications. At present, many large-scale distributed applications need to rely on this information for performance optimization. For example, in the IPTV application based on the P2P mode, the available bandwidth of the path to the peer node The level of video transmission will directly affect the quality of video transmission; based on CDN streaming media services, the optimal server can be selected according to network performance to provide services for users; in Skype and other VoIP systems that need to use relay nodes to bridge host nodes behind NAT / firewalls , the performance information can help select the node with the best pe...
