Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings, but these embodiments do not limit the present invention, those of ordinary skill in the art make structural, method, or functional changes based on these embodiments All are included in the scope of protection of the present invention.

[0041] Such as image 3 In one embodiment of the present invention shown, the present invention provides a network performance detection system, the system includes:

[0042] An access control rule module 30, configured to create N access control lists corresponding to N service flows, divide the N service flows into M groups of service flows, and perform rule matching on the N service flows;

[0043] The path configuration module 31 is used to create N shadow memories, which are associated with the N access control lists, and M groups of shadow memories are correspondingly provided, and each shadow ...

Abstract

The invention discloses a network performance detection system. According to the invention, a measurement period is divided into a plurality of time slices; a plurality of shadow memories are correspondingly arranged for one state memory; therefore, in a measurement period, message dyeing operation is started for a plurality of service flows, the message dyeing operation of one service flow in each group of service flows is controlled to be started in each time slice, a system timestamp is stamped on a dyed message, and the system timestamp is sent to a server. Correspondingly, the invention further discloses a network performance testing method. According to the invention, the resources of the state memory can be flexibly expanded so as to meet the network performance test of more serviceflows.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network performance detection system and method. Background technique [0002] In the architecture of communication equipment based on hardware forwarding planes such as hardware application-specific integrated circuits (ASICs) or network processors, such as routers, switches, passive optical networks, packet transport networks, and sliced ​​packet networks (SPNs), hardware The state memory function realizes functions such as TCP connection state monitoring and service flow delay measurement. Take the service flow delay measurement function based on the alternate coloring method of RFC8321 as an example. Such as figure 1 In the network elements of the transport network shown, in each measurement period, the sending end performs delay coloring on one of the packets of the service flow under test in this period, and records the ingress timestamp t of the packet 1 , and ...
