Double-cache message processing method with control information separated from data

Abstract

The invention relates to the field of communications, and particularly provides a double-cache message processing method with control information separated from data. The method aims to solve the problems that an existing message forwarding mechanism is too complex and the phenomenon of cache deadlock is likely to happen. For the purpose, the method includes the steps that an independent data cache and an independent control information cache are provided; data of a message are written into the data cache; the length of the message and the starting write-in address are calculated, and stored in the control information cache; control information of the message is written into the control information cache; the message is read out from the data cache according to the length of the message in the control information cache and the starting write-in address. Compared with a traditional forwarding mode that the control information and data are stored in the same cache, the design operation is greatly simplified through the method, and the phenomenon of read-write control deadlock is avoided.

Description

technical field [0001] The invention relates to the communication field, and specifically provides a double-buffering message processing method for separating control information and data. Background technique [0002] A message is a data unit exchanged and transmitted in the network, that is, a data block to be sent by a station at one time. The message contains the complete data information to be sent, its length is very inconsistent, and the length is unlimited and variable. As the unit of network transmission, the message will be continuously encapsulated into groups, packets, and frames during the transmission process. The way of encapsulation is to add some information segments, which are the data organized by the message header in a certain format. There are message types, Message version, message length, message entity and other information. [0003] The existing message forwarding mechanism is to use a single cache to store control information and data together, a...
