End-to-end network path discovery method based on multiple protocol tests

Abstract

The invention provides an end-to-end network path discovery method based on multiple protocol tests. The method includes: setting A and B as two endpoints in the network; when a path from the A end point to the B end point is obtained, based on UDP, TCP, ICMP and other protocols, using a fixed quintuple in each round to ensure that the same path is found in one path; using multiple kinds of quintuples of UDP and TCP and ICMP to carry out multiple tests. The path is more accurate, a fixed quintuple test is used for each test, a relatively more accurate path can be obtained, the path far more than that of a traditional mode can be obtained through multiple times of traversal, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an end-to-end network path discovery method based on multiple protocol tests. Background technique [0002] Due to the development of science and technology and the improvement of human living standards, in the Internet era, with the popularization and development of the network, the scale and complexity of the network have doubled, and the difficulty of tracking network problems has also doubled with the increase in scale. [0003] In tracking network problems, it is necessary to determine whether packet loss occurs in the network between the request initiator and the server. This article mainly discusses the discovery method of network packet loss from one end to another end in the network. However, the traditional solution can no longer meet the needs of the current situation. The traditional solution is generally as follows: [0004] The traditional routing analysis me...

[0016] 2. Incomplete paths: The traditional solution does not particularly consider the network multipath problem, and often only obtains part of the path, but cannot obtain all paths, for example:

[0019] 3. Cannot completely cover the paths of P1, P2, and P3: the traditional solution does not do special processing for P1, P2, and P3, but only focuses on the path relationship of S1, S2, S3, S4, and S5, and does not focus on P1, P2, and P3 The situation of each sub-path in
