Problems solved by technology

Doing this over a high-speed network link consumes a lot of storage space and CPU resources for cache lifetime management
This makes the hardware cost required to collect and process complete HTTP data high, which cannot be realized on low-end and mid-range network devices with limited processing capabilities

Abstract

The embodiment of the invention discloses an HTTP (Hyper Text Transport Protocol)-based information filtering overlaying method and device. The method comprises the following steps: removing HTTP redundant information contained in a downlink first TCP (Transmission Control Protocol) package for carrying HTTP package, wherein the HTTP redundant information is the unnecessary information browsed by a browser in the HTTP package; calculating a residual carrying space of the TCP package after the redundant information is removed; and if the size of the residual carrying space is not less than the size of the target content, putting the target content into the residual carrying space, acquiring the processed TCP package and sending the processed TCP package to a downlink port. The device is used for realizing the method. According to the HTTP-based information filtering overlaying method disclosed by the embodiment of the invention, the network link equipment can realize the overlaying of the HTTP package at minimal cost.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an HTTP-based information filtering and superimposing method and device. Background technique [0002] The original purpose of designing HTTP (Hyper Text Transfer Protocol, Hypertext Transfer Protocol) is to provide a method for publishing and receiving HTML (Hyper Text Markup Language, Hypertext Markup Language) pages. Resources requested through the HTTP or HTTPS protocol are identified by uniform resource identifiers (Uniform Resource Identifiers, URL). [0003] The development of HTTP is the result of the collaboration between the World Wide Web Consortium (W3C) and the Internet Engineering Task Force (IETF), which eventually published a series of RFCs, the most famous of which is the June 1999 RFC2616, published in July, defines a version of the HTTP protocol that is widely used today——HTTP 1.1. In December 2014, the Hypertext Transfer Protocol Bis (httpbis) working gro...
