Method and device for processing message

Abstract

The embodiment of the invention relates to a method and a device for processing message, wherein the method comprises: receiving the message and storing the message into a buffer memory unit; determining a buffer memory queue corresponding to the message; judging whether the sum of the length of the message and the actual queue length of the buffer memory queue is less than or equal to the queue allocation length in the buffer memory queue; if so, adding the message to the buffer memory queue by updating the content of a buffer memory item message pointer in the buffer memory list of the buffer memory queue as the starting memory address of the buffer memory unit containing the message; and updating the buffer memory item index and the queue enqueueing index in the buffer memory list to establish the new index for the message; and updating the actual length of the queue length into the actual length after the message is memorized. The embodiment of the invention provides a method for dynamically adjusting the buffer memory bandwidth of the queue, in the method, the massage is stored in the buffer memory of the queue by judging sum of the length of the massage and the actual lengthof the buffer memory of the queue as well as the configurated length of the queue in the buffer memory of the queue; and the buffer memory of the queue is changed according to the change of the chainwidth so as to improve the problems of the transmission delay because of overlarge buffer memory space and the shaking packet loss because of over-small buffer memory space of the queue and enhance the communication quality.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a message processing method and device. Background technique [0002] Due to the simple and practical design idea of ​​IP technology and rich and colorful applications, the all-IP (ALL IP) networking mode has become the evolution trend of the current network. However, in the current network environment, in order to make full use of the existing access line resources, there is a demand for compatible interconnection between the existing access network and the IP network. [0003] Networks based on transmission modes such as time division multiplexing and time division multiplexer (Time Division Multiplex and Multiplexer; hereinafter referred to as: TDM) technology and microwave technology need to be interconnected with the IP network through network element devices. Taking the network based on TDM technology as an example, the TDM network mainly uses the TDM...

Problems solved by technology

However, the broadband of the TDM network logic channel will change due to the change of the number of bound time slots. The broadband network (such as ADSL (Asymmetric Digital Subscriber Loop, Asymetric Digital Subscriber Loop) / ADSL2+ / G. Digital Subscriber Line, Single-pair High-speed Digital Subscriber Line) / Microwave link and other networks) The bandwidth of the link in the network will change due to changes in environmental factors such as weather conditions, interference signals, and distances. In the preset buffer capacity When the link bandwidth is too large, if the link load is heavy, that is, when the bandwidth becomes larger, the transmission delay of the link will increase; when the preset buffer capacity is too small relative to the link bandwidth , if the link may not be able to adapt to the packet jitter of the IP network, it may easily cause packet loss

The increase of transmission delay and packet loss both lead to the decline of transmission quality
