Embodiment Construction

[0032] Due to the specificity and particularity of the network processor architecture, the compression transmission method implemented in the present invention is a relatively special but effective compression transmission method. Typical applications of the present invention are: applicable to all IP / PPP-based voice data / real-time data / multimedia data communication equipment transmission systems, including the CDMA2000 ABIS interface and A3 / A7 interface specified by 3GPP2, especially suitable for multi-device, large Transmission system for traffic IP / PPP data access.

[0033] In the network processor, the invention adopts the establishment of the session environment table, the master-slave hash index table, and the asynchronous processing mode in which the maintainer and the user are separated, so as to solve the problem of limitation of the instruction space of the micro-engine. The hash operation is used to locate the session environment table. Compared with the method of t...

Abstract

The invention is a network processor based compressing and transmitting method implementing message protocol, making cUDP treatment on messages by multiple microprocessors, adopting a compression-decompression-in-one mode to build a conversation environmental table, establishing a master-slave Hash index table in kernel processor to index the conversation environmental table, setting a counter domain in the conversation environmental table to make transmission logic processing on full-head and compressed-head messages, adopting UID and CID groups as compression environmental identification to enlarge compressed space and receive cUDP messages of more devices, adopting a microprocessor multithread parallel processing structure, performs cUDP compression-decompression two-way processing, maintains two groups of queues: one for cUDP compression and the other one for cUDP decompression, thus implementing large-flux user message protocol compression and transmission in network processors.

Description

technical field [0001] The invention relates to a method for realizing compressed transmission of user message protocol, in particular to a method for realizing compressed transmission of user message protocol by using network processing. Background technique [0002] At present, the telecommunication network is in the initial stage of upgrading. The development of Internet technology and IP (Internet Protocol) technology has had a profound impact on the development of the entire telecommunication network. Traditional circuit switching is gradually replaced by IP packet technology, and mobile technology is moving towards All IP development. One of the important ideas of all-IP is to use IP as the transport layer protocol of the entire telecommunication network to increase the flexibility, unity and scalability of the system. However, due to the consideration of operating costs, for a long period of time, a large number of low-speed links will still be used for data transmis...
