Problems solved by technology

[0011] As a tool, for the TBIT 21 used in the above-mentioned conventional protocol test system, its minimum function is to reproduce the problem of the TCP/IP protocol, but its main purpose is not to reproduce the problem, so the problem is that the tool cannot accurately reproduce the TCP/IP protocol. Problems with the IP protocol
[0012] Furthermore, when the tools of the TBIT 21 and the network simula

Abstract

It is an object of the present invention to execute testing to accurately reproduce problems of a TCP/IP protocol without mistakes without knowledge or skilled techniques of the TCP/IP protocol and reduce effort required for carrying out testing. The traffic generation apparatus 32 sends the test traffic data 55 to the testing server apparatus 41. The response traffic data 57 which is the response data of this test traffic data 55 is processed in a pseudo-communication environment constructed in the communication network emulator apparatus 37 to reproduce problems of the TCP/IP protocol. Settings and control for realizing this reproduction are automatically carried out by the testing control apparatus 44 using predetermined setting information 45a, 45b, 45c and control information 47a, 47b and 47c.

Description

technical field [0001] The present invention relates to a protocol testing system and a protocol testing method which reproduce problems in TCP / IP (Transmission Control Protocol / Internet Protocol), which is an Internet architecture technology. Background technique [0002] One of the Internet infrastructure technologies is the TCP / IP protocol. The TCP / IP protocol is implemented in various computers and has recently been introduced into small electronic devices such as Personal Digital Assistants (PDAs) and cellular phones. These small electronic devices can also connect to the Internet and run web applications. According to the needs of Internet users, new functions have been added to the TCP / IP protocol one after another, but with the realization of these new functions, many problems of the TCP / IP protocol have also appeared. [0003] As a reminder, the developers of the TCP / IP protocol used information about problems learned from users and other information to reproduce ...
