Embodiment Construction

[0041] The test data packet encapsulation method and device, network device performance test method and system provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0042] The present invention aims at the defect that the existing packet testing tool calls the packaged protocol stack in the operating system to complete the packaging of the test data packet, in order to make the transmitted data packet meet the protocol stack packaging format of different network interfaces, and at the same time, in order to be able to set each layer The parameters of the protocol header provide a test packet encapsulation method, which can flexibly customize the encapsulation format of the protocol stack and modify parameters, such as Figure 4 As shown, the method includes:

Abstract

The invention discloses a test data packet packaging method, relating to the field of network performance testing. The test data packet packaging method comprises the following steps of: constructing protocol units of different protocols by a network access system capable of bypassing an operating system to invoke a network device driver for independently transmitting data, and configuring data items opened to users in the protocol units, wherein the protocol unit of each protocol utilizes a data format defined by the protocol; and configuring a level of each selected protocol unit and modifying the data items opened to the users in the selected protocol unit according to the protocol units selected by the users by using the network access system, and packaging test data packets. According to the test data packet packaging method and equipment disclosed by the invention, the protocol stack packaging formats of the test data packets can be customized and related parameters can be modified by the users, performance tests of various network devices can be met, and great convenience is brought for an abnormal test, even network attack can be simulated.

Description

technical field [0001] The invention relates to the technical field of network performance testing, in particular to a test data packet encapsulation method and equipment. Background technique [0002] A protocol is a term used to describe the rules for exchanging information between processes. In the network, two entities that communicate with each other are located in different geographical locations, and the two processes on them communicate with each other. They need to coordinate their actions and achieve synchronization by exchanging information, and the exchange of information must follow a pre-agreed process. conduct. [0003] The protocol stack refers to the sum of all layers of protocols in the network, which vividly reflects the process of file transmission in a network: from the upper layer protocol to the lower layer protocol, and then from the lower layer protocol to the upper layer protocol. [0004] Different entities in the network have different network i...
