Method and apparatus for modifying and forwarding message in data communication network

Abstract

The invention discloses a method for modifying and forwarding a message in a data communication network. The method comprises the following steps: extracting the description information at the starting part of a message as a message descriptor, and storing the message apart from the message descriptor in a segmentation mode; according to message descriptor information, searching for a prestored message modification description list, and obtaining modification parameters needed for message modification; according to the obtained modification parameters, determining motion needing the message modification, grouping message segments needing modification according to motion types, and performing the modification; and distributing and recombining the message segments according to port numbers, performing re-splicing to form a complete message for sending to an external interface according to a time sequence. The invention also discloses an apparatus for modifying and forwarding a message in a data communication network. By adopting the method and apparatus provided by the invention, the prestored message modification description list can be modified through the external interface to increase, change or delete the message modification parameters so as to be adaptive to the demands of services of different types, the design workload is substantially reduced, and the maintenance time, cost and complexity are reduced.

Description

technical field [0001] The invention relates to the field of message processing in a data communication network, in particular to a method and device for modifying and forwarding a message in a data communication network. Background technique [0002] With the rapid development of various new services centered on Internet Protocol (IP), Internet Protocol Telephony (Voice over Internet Protocol, VoIP), Internet Protocol Television (Internet Protocol Television, IPTV), third-generation mobile communication The emergence of services such as The 3rd Generation Telecommunication (3G) technology, Long Term Evolution (LTE) technology, and Metro Ethernet dedicated line not only increase the demand for bandwidth, but also require more detailed user differentiation and more efficient data service management. reliable. The packetization of services promotes the evolution from access network, bearer network, and core network equipment to the next-generation network with packet switchin...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from this that the existing design method will bring two problems: first, with the increase of chip functions, the area and power consumption of the chip will increase greatly. balance, it is necessary to tailor some functions, which is often what chip designers do not want to see; second, in order to achieve some new requirements, or to address some changes in requirements, on the basis of existing processing logic. Or the workload of modifying the logic code is increasing, the later maintenance of the code becomes more and more complicated, and the time and cost required to maintain the code are also greatly increased
