Abstract

The invention discloses a line card device provided with strong QoS function and a designed method thereof. The method comprises the following steps that: an upper sending channel between a plurality of network processors of the line card and a Host CPU is provided with a flow managing module, an upper sending channel bus is connected with the flow managing module by a plurality of network processors of the line card, a plurality of network processors classify the received messages and pick up the sent messages to be sent to the flow managing module; the flow managing module classifies and caches the messages sent by different network processors, the priority level of the send messages is divided and sorted as well as sent orderly; the Host CPU processes messages sent by different network processors by the flow managing module, the processed messages are respectively sent to a UPC and sent to the corresponding network processors by the flow managing module. The invention overcomes the shortcomings in the designed proposal of the line card and improves the quality of the whole device QoS finally.

Description

technical field [0001] The present invention relates to the field of line card design for telecommunication routers, in particular to a line card device and its design for realizing a strong QoS (Quality of Service) function in the message sending path between a network processor and a Host CPU Methods. Background technique [0002] Web browsing, E-mail, etc. have become the basic applications of the network in modern networks. The emergence of various emerging services requires future network core equipment to be equipped with Internet access, multimedia video, 3G R5 / R6, 3G packet domain, NGN (next First Generation Network, Next Generation Network) business key customer dedicated line, digital on-demand and other business processing functions integrated together. [0003] The number of users continues to increase, and the access bandwidth of each user is gradually increasing. The division of user groups has higher requirements on the network core processing equipment in t...
