Problems solved by technology

The simulation of the TCP server is completely realized by using the TCL high-level language. Therefore, after the connection with the upper-layer application protocol is established, the processing of the heartbeat detection message is generally more frequent. Efficiency has a greater impact; in addition, for the simulation of the TCP server, because TCL itself lacks the functions of editing, sending, and processing messages, the actual testing work is very cumbersome and the workload is heavy

Embodiment Construction

[0040] The core idea of ​​the present invention is: set up the object under test through the TCP relay device, i.e. the TCP connection between the TCP client and the test tool, i.e. the simulated TCP server, and forward data packets, simplifying the simulation of the TCP server to be equivalent to The emulation of the TCP client realizes the test of the TCP client simply and efficiently.

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0042] Fig. 2 is the flow chart of the present invention's test TCP client, and measured object is TCP client, and test tool is the TCP server of emulation, comprises the following steps:

[0043] Step 20a: Establish a TCP connection between the measured object and the TCP relay and maintain the connection.

[0044] In this step, the TCP client can adopt...

Abstract

The disclosed method to test TCP comprises: with TCP connection and data transfer technique, simplifying simulation to TCP server by a simulation tool, and realizing the opposite test with high efficiency.

Description

technical field [0001] The invention relates to an Ethernet test technology, especially a method for testing a Transmission Control Protocol (TCP) client. Background technique [0002] As we all know, TCP provides a connection-oriented byte stream service, which means that two TCP application entities, such as a TCP server and a TCP client, must first establish a TCP connection before exchanging data with each other. Includes three processes: [0003] 1) The requesting end, usually referred to as the client, sends a TCP message containing a synchronization (SYN) mark, that is, a SYN message, and the SYN message indicates the port of the server and the initial TCP sequence number of the TCP connection; [0004] 2) After receiving the client's SYN message, the server will return a synchronous confirmation (SYN+ACK) message, indicating that the client's request is accepted, and at the same time add one to the TCP sequence number; [0005] 3) The client also returns an acknowl...
