Link time delay detection method and device, equipment and medium

Abstract

The invention discloses a link time delay detection method and device, equipment and a medium. The method comprises the following steps: taking a network equipment port on at least one side of each link in an aggregation link as a source port, and enabling the source port to send an Internet packet explorer Ping test message to a destination port; obtaining a test result of the Ping test message,and determining a common source port to which the Ping test message returns; according to the test result, determining a first time delay from sending of the Ping test message from the source port toreturning to the public source port and a second time delay from sending of the Ping test message from the public source port to returning to the public source port; and determining the time delay ofeach link in the aggregated link according to the first time delay and the second time delay. According to the embodiment of the invention, the time delay of each link in the aggregated link can be detected.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a detection method, device, equipment and medium of link time delay. Background technique [0002] At present, communication operators generally adopt a multi-port physical link aggregation mode in an Internet Protocol (IP) network interconnected between networks, and interconnect devices using aggregated links. Latency is one of the important indicators reflecting the network quality between two network devices, which directly affects the service signal quality flowing between the devices and ultimately affects the user's service perception. [0003] To detect the time delay between network devices, it usually deploys test tasks between network devices, and obtains the network quality index of time delay by recording the test tasks. Usually there are two situations: [0004] The first case: if figure 1 As shown, a Network Quality Analyzer (NQA) test is deployed...

Problems solved by technology

The quality of other member links is not measured and monitored

[0011] In addition, a small number of equipment manufacturers increase the aggregation member information field in the reserved bytes of the TWAMP control message, and negotiate the sending port and reflection port of the devices at both ends through the control message before sending the test message. Independent testing of member links, but the definition and use of this reserved byte is currently stipulated in the non-Request For Comments (RFC) standard, which belongs to the customization of a small number of equipment manufacturers

There is a problem of intercommunication between devices from different manufacturers, which limits the practical application in the network
