Embodiment Construction

[0052] The principle of the present invention is as follows:

[0053] In the hardware design of the network switch or communication node, the message classification output controller of the communication system adopts shared storage and linked list management to realize message classification storage and retrieval.

[0054] The shared storage unit is used as message storage to store messages. The shared storage unit is a continuous storage area, logically divided into multiple message storage blocks of equal length, numbered in order, and each message storage block can store one message .

[0055] When the system is initialized, all the message storage block indexes are put into an idle message index table; when the message is written, the message storage block index is obtained from the idle message storage block index table, the message storage block address is calculated, and the message content Write to the corresponding message storage block, look up the message attribute table...

Abstract

The invention provides a method and a controller for the classified output of messages in a communication system, and mainly solves the problems that that a conventional method and a conventional controller have high demand on storage resources and high cost, and are low in utilization ratio and difficult to implement. The method for the classified output of the messages in the communication system comprises three steps, namely, system initialization, message writing and message reading. The controller for the classified output of the messages in the communication system comprises an input control unit, a memory unit, an output control unit, a message attribute list unit, an idle message block concordance list unit, a message searching list unit and an output control list unit. The methodand the controller for the classified output of the messages in the communication system, which are provided by the invention, have good flexibility, the number of output ports of a message queue management controller for classification is configurable, and the depth of output queue is configurable.

Description

Technical field [0001] The invention belongs to computer hardware technology, and relates to a hardware circuit realization method for message queue management in switches and communication nodes. Background technique [0002] In the design of high-speed communication systems, in order to ensure system transmission efficiency, communication service quality, message communication transmission certainty, bandwidth isolation, and message transmission efficiency, it is necessary to build a multi-priority queue in the communication node, and an output queue in the switch. The implementation of these queues requires a lot of memory resources. [0003] Communication scheduling management must be realized based on the classified storage of messages, but in traditional communication systems, storage space is fixedly allocated for each message, and the utilization of storage resources is insufficient. The hardware of switches and communication nodes is often limited by FPGA storage resource...
