Embodiment Construction

[0065] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0066] In most protocol test scenarios, in order to better simulate the live network environment, traffic test frames and protocol test frames are configured at the same time. In some cases, traffic test frames are simulated attack traffic, and in some cases, traffic test frames are related to protocol testing. A large amount of business traffic (such as route-base...

Abstract

The embodiment of the invention discloses a filtering method and device for Ethernet protocol testing. An Ethernet testing frame is obtained in a process of uploading the Ethernet testing frame to a CPU, verification of the Ethernet testing frame is carried out by employing a label domain verification algorithm, and the Ethernet testing frame meeting a label domain verification condition is determined as a to-be-determined testing frame. In order to avoid misjudging the protocol test frame as the traffic test frame, secondary verification is performed on the to-be-determined test frame according to the field selected from the target position of the to-be-determined test frame, the target position is the position of the field representing the sending sequence of the traffic test frame in the label domain of the traffic test frame. If the field meets the preset condition, it is determined that the to-be-determined test frame is a traffic test frame, and the traffic test frame is filtered. By performing secondary verification on the to-be-determined test frame intercepted for the first time, whether the to-be-determined test frame is a flow test frame or not is determined, a protocoltest frame is prevented from being misjudged as the flow test frame, the problem that the protocol test frame is intercepted by mistake is solved, and the correctness of protocol test is ensured.

Description

technical field [0001] The present application relates to the field of network equipment testing, in particular to a filtering method and device for Ethernet protocol testing. Background technique [0002] The Ethernet tester is a special test instrument used to generate Ethernet network traffic and inject it into the device under test, and obtain the information of the device under test by analyzing the Ethernet frame returned from the device under test. [0003] Flow test and protocol test are two essential functions of Ethernet tester. Simply put, flow test is to inject the flow test frame of specified rate into the device under test (Device Under Test, DUT) by the Ethernet tester. Observing the test frame return of the device under test to know the status of the device under test; protocol testing refers to the Ethernet test instrument simulating the node (server or client) running the protocol on the Ethernet, and interacting through normal and abnormal protocol test fr...
