Apparatus and method for TCP protocol and data recovery based on parallel processing

Abstract

This invention provides a TCP protocol based on parallel processing and data reduction device and method thereof. The device comprises a network message capturing device, a TCP protocol analysis and restructuring device, a restructuring data access device and an application layer data notifying device. The method comprises a network message capturing process, a TCP protocol analyzing process, a TCP data restructuring process and an application layer notifying process. The TCP protocol data analysis demand under high-traffic network environment can be satisfied by using a single point calculating platform via this invention, without extra adding the software/hardware environment, and having higher cost performance; the TCP data restructuring strategy can be customized based on the practical environment, thereby more effectively using the system resource, and maximizing the utilization ration thereof; the finally realized message analysis technology has stronger portability, which can be satisfied with the most current running environment configurations.

Description

(1) Technical field [0001] The invention relates to a device and method for assisting network protocol analysis and information restoration by using network interface and computer technology. In particular, a system and method for completing TCP protocol and data restoration therein by using parallel processing technology. (2) Background technology [0002] With the popularization of Internet technology all over the world, its application range goes deep into the government, military and even various fields related to the national economy and people's livelihood. The Internet has brought great convenience to people's life and work. Network protocols are the core technologies supporting the Internet, among which the most widely used is the TCP / IP protocol family. [0003] The Internet was originally proposed for information sharing, and it was designed and implemented with relatively simple motives. With the continuous expansion of the application field, especially to comm...

Problems solved by technology

The development of network hardware equipment has greatly improved network performance, and the order of magnitude of network bandwidth is increasing day by day. Traditional, pure software-based protocol analysis technology has received great challenges. Therefore, VLSI (UNPXRev / ew, 1987, 5(9): 70 ), shared storage multiprocessor platform (the number of processors is greater than 2) (research on multi-threaded TCP / IP protocol restoration technology. High Technology Communication, 2003 (11): 15~19) and other schemes were proposed respectively, but these schemes are not Requires high hardware cost
