Attribute identification method for data processing channel buffer matching

Abstract

Disclosed is an attribute identification method for data processing channel buffer matching. The method includes the following steps: when an application data packet flows through a processing channel, defining cache attributes; setting the cache attributes of the current application data packet in an input or output buffer area; adopting the cache attributes of the current application data packet to match with cache attributes of a previous or later application data packet in the buffer area; if matching is successful, calling the previous or later application data packet in the buffer area to serve as cache output through the cache attributes of the previous or later application data packet; if matching fails, newly adding the current application data packet to the buffer area, and adopting the current application data packet as cache output. The processing channel is established by the on-line dynamic link method. By the method, accuracy of data processing is improved, and flexible combination among modules is realized. Memory read-write operation can be reduced effectively, and efficiency of processing when the application layer data packets flow through all the modules is improved.

Description

technical field [0001] The invention relates to the technical field of computer software application layer protocol processing acceleration, in particular to an attribute identification method for data processing channel buffer matching. Background technique [0002] At present, the construction of many application systems and network security systems must deeply analyze and deal with the application layer protocols above the TCP / IP layer. The application layer protocol is generally more complex. Under the current existing technical architecture, when performing application layer protocol processing, it is necessary to use multiple independent modules successively. The connection between these modules is complicated, which greatly reduces the flexibility of the system, and the operation of each module on the buffer is blind. When the data flows through each module, the buffer between the modules matches (we refer to the realization of module connection as And the buffer op...

Problems solved by technology

[0004] The above-mentioned technical solutions to optimize the buffer operation can greatly improve the protocol processing performance, but these technical solutions focus more on the relatively simple underlying protocols such as TCP, which are not suitable for the application layer protocol processing under the existing framework, and the current In existing technologies, memory access operations are frequent, and sequential query is used, and the efficiency of cache access is low.
