Problems solved by technology

[0005] As can be seen from the above process, each IP message packet that includes an SCTP message must be parsed on the IP processor unit. According to the source IP address, source SCTP port, destination IP address, and destination SCTP port in the parsed SCTP message The address port information of the four fields is searched and distributed to different SCTP processor units. Obviously, the above SCTP message distribution mechanism will consume more time. When there are a large number of IP messages that need to be processed by the IP processor unit, the message distribution The search and judgment in the process will have a certain loss on the processing and real-time performance of the system, so it will reduce the distribution efficiency of SCTP messages, and then reduce the performance of the system

Embodiment Construction

[0017] Due to the separation of the processing unit for processing IP messages and the processing unit for processing SCTP messages in the system, it is necessary for the processing unit of IP messages to send the SCTP message to the corresponding SCTP processing unit. However, since there is no fixed correspondence between the processing unit of IP message and the processing unit of SCTP message, it will inevitably lead to a large number of search and judgment operations in the process of SCTP message distribution, which will inevitably have a certain impact on the performance of the system. .

[0018] In fact, according to the SCTP protocol, each SCTP message packet contains an authentication tag field (TAG field). For the SCTP connection of system B), they are randomly generated by the two systems respectively, and are mutually determined through the INIT and INIT-ACK message interaction process when the SCTP connection is established. All messages transmitted on this SCTP...

Abstract

This invention disclose a method for distributing messages of a stream control transmission protocol(SCTP), in which, when setting up connection of SCTP, its unit sets information of its own unit in TAG field value according to its own number and to transfer it to the other end connected with SCTP, thus, when the IP processor unit receives SCTP information, it distributes SCTP information to relates processor unit according to the information in TAG value to realize quick distribution of SCTP information to increase the distributing efficiency and the system performance.

Description

technical field [0001] The present invention relates to a message control method of Stream Control Transmission Protocol (SCTP). Background technique [0002] Stream Control Transmission Protocol (Stream Control Transmission Protocol, SCTP) is a stream control transmission protocol for IP networks, which is specially improved on the basis of the original Transmission Control Protocol (TCP) for the transmission of signaling messages on IP networks. It can guarantee Reliable, ordered delivery of signaling messages. SCTP provides connection-oriented data packet transmission, does not need the upper layer to realize the data demarcation function, and has many advantages such as good real-time performance, high security, avoiding line head blocking, and supporting multi-homing. SCTP is proposed as a transport layer protocol in the signaling transport protocol stack (SIGTRAN), and its status in SIGTRAN is as follows: figure 1 shown. figure 1 Among them, STCP is located between ...
