Establishment of TCP data flow connection by hardware

Abstract

The invention provides a hardware method for building a TCP data stream connection. A hardware module is used to make deep analysis for the data packet, and in term of quintuple and state information to build communication connection for the packet. When using the hardware connection, each functional module works independently so that opening the TCP connection doesn't reduce the efficiency of other modules. Meanwhile RAM read writing speed by hardware is also very high to make the data format of read writing able to be simplified.

Description

technical field [0001] The invention relates to communication technology, in particular to a connection method of network data flow. Background technique [0002] Since most of the current network applications are based on the TCP protocol, only by establishing and maintaining connections for TCP streams in the system can we check, track, count and manage stream-based applications well, which has also become a common feature of various networks. Application systems, especially firewalls and other functions that often need to be implemented. According to the provisions of the TCP protocol, TCP is connection-oriented, so the network protocol stipulates a relatively complicated scheme for establishing and tearing down connections. In this way, while ensuring the reliability of connection establishment, it also increases the difficulty of establishing and maintaining the connection. [0003] In the past, the technology of establishing a TCP connection was usually based on soft...
