Embodiment Construction
[0034] The present invention here provides a line card device with strong service quality function and a design method thereof to solve the problem that the existing line card design only pays attention to the realization of the QoS function at the data level, while ignoring the QoS function at the control level. problem. Specific embodiments are described in detail below, but they are not intended to limit the present invention.
[0035] Attached below figure 2 with 3 The implementation of the technical solution of the present invention will be described in detail.
[0036] figure 2 It is the structure diagram of the line card device with strong QoS function in the present invention. A traffic management module 205 (such as the transmission channel between the network processors 201, 202 and the Host CPU (host central processing unit) 203 is added figure 2 ), multiple network processors all connect the upload channel bus to the traffic management module 205, and by adding the t...

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 telecommunication-level router line card design, in particular to a line card device and its design for realizing a strong QoS (Quality of Service) function in a message transmission path between a network processor and a Host CPU Methods. Background technique [0002] In modern networks, Web browsing, E-mail, etc. have become the basic applications of the network. The emergence of various emerging services requires the core equipment of the future network to have Internet access, multimedia video, 3G R5 / R6, 3G packet domain, NGN (below Next Generation Network (Next Generation Network) business key customer dedicated line, digital on-demand and other business processing integrated functions. [0003] The number of users continues to increase, and the access bandwidth of each user is gradually increasing. The distinction of user groups places higher requirements on the processing of data transmission delay, netwo...
