The Design of HTTP Protocol Parser Based on Parallelization

At present, more and more network applications require deep parsing of data packets. That is, not only identifying the protocol of the packet, but also extracting more useful information, such as the URL, the cookie of the HTTP message. Aiming at the above problems, this paper designs an HTTP protocol parser based on multi-core platform. The main function of the parser is to identify the request packet and response packet in the HTTP access data stream, as well as the response packet matched by each request packet, and can output some data fields of interest for the application.
