Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] see figure 1 , in the multi-task scheduling method of the measurement probe of the present invention, the measurement probe uses multi-thread technology, and the threads communicate through mutexes and condition variables, so that they can receive and respond in real time from different measurement task management hosts (management end) sent tasks. Multi-threading includes receiving task thread and extracting and executing task thread. The receiving task thread is responsible for monitoring the test tasks sent by multiple measurement task management hosts on the network, and inserting tasks into the task queue to complete the receiving of test tasks. The task queue is a linked list that saves task information. Threads add or delete task queues through mutexes.

[0020] A mutex is used to ensure that only one thread is executing a piece of code for a ...

Abstract

The invention discloses a multi-task dispatching method of a measuring probe. The measuring probe uses a multithreading technology, the threads communicate with each other by a mutual repulsion lock and conditional variables so as to receive and respond to tasks sent from different management terminals in real time. The method provided by the invention can carry out flow acquisition and statistical analysis to a plurality of network segments, or carry out performance test to certain servers in the network at the same time, thus greatly shortening testing time and improving work efficiency.

Description

technical field [0001] The invention relates to network communication and network measurement technology, in particular to a multi-task scheduling method of a measurement probe. Background technique [0002] At present, in network communication and network measurement technology, to measure the flow and performance data of multiple network segments or perform performance tests on multiple servers on the network, a measurement probe (or monitoring host) can be placed on each network segment . [0003] If it is required to perform multiple specified tasks on a measurement probe at the same time, such as collecting traffic and statistical analysis on multiple network segments, or performing performance tests on some servers in the network, and then sending these test results to another specified On the server, the usual method is to execute a task first, and then receive another task, so that the cycle continues. The efficiency of this method is not high, especially when perf...
