Abstract

The invention provides a test method and a test system of openflow switch table body capacity. The test method includes: obtaining matching domains supported by a target logic flow table needed to be tested and arranging default matching action of the logic flow table; adding logic flow table items of corresponding matching domains into the target logic flow table, wherein the priority level of the flow table items is sequentially and progressively increased from 1; transmitting messages of the matching domains and monitoring openflow protocol messages; and when monitoring that the protocol messages are processed according to the default matching action, recording the priority level P1 of the flow table items and lastly added into the target logic flow table, wherein the table body capacity C of the logic flow table to be tested meets that C=P1 at the time. The test method and the test system can automatically achieve testing of the switch table body capacity and meet estimation requirements of various large manufacturers for switch system performance, the testing process needs no manual intervention, the testing speed is fast, and the testing result is accurate.

Description

technical field [0001] The invention relates to the technology in the field of Ethernet, in particular to a test method and a test system for the table item capacity of an Openflow switch. Background technique [0002] At present, the rapid development of the Internet, the huge application scale and the importance of its status are far beyond the imagination of the designers. However, the current Internet mainly has the following disadvantages: there is no unified management, network forwarding mechanism and strategy within a specific scope Single, it is difficult for operators to optimize their own networks to the maximum extent, and the functions and protocols used by traditional switches for forwarding are numerous and complex, difficult to configure, and the system is prone to errors. In order to deal with the above-mentioned disadvantages, people have proposed the Openflow switch, which separates the packet forwarding and forwarding strategy on the traditional switch, a...
