Embodiment Construction

[0045] The technical solutions of the present invention will be further described in more detail in conjunction with the accompanying drawings and specific embodiments.

[0046] Such as figure 1 As shown, it is a schematic diagram of the device architecture of the network processor traffic shaping of the present invention. The device 100 includes: a queue management module 10 , a queue scheduling module 20 , a service traffic shaping module 30 and a port traffic shaping module 40 .

[0047] The queue management module 10 is configured to perform message enqueue, dequeue and queue congestion processing according to different business classifications of data messages.

[0048] Specifically, at first the queue management module 10 enters the data message into different queues according to different business classification strategies; Packet is delivered to port traffic shaping module 40, informs port traffic shaping module 40 to process the message of going out; Early Detectio...

Abstract

The invention discloses a flow shaping implement method based on the network processor and the device therof, wherein the method includes: a queue management step, used for carrying the enquene, the dequeue and queue congestion processing of the message; a queue dispatching step for carrying the queue dispatching based on the port and the operation according to the message scheduling strategy; an operation flow shaping step, for completing the flow computation of different operation message to determine whether the queue dispatching of the operation is delayed according to the message flow; a port flow shaping step used for carrying the queue dispatching based on the port for the message input end queue of the output operation queue, completing the flow computation of the port according to the port flow to delay the queue dispatching of the part or transmit the message of the port queue. The invention realizes the second grade flow shape based on the port and the operation without special TM chip.

Description

technical field [0001] The invention relates to broadband communication technology in the field of data communication, in particular to a network processor-based flow shaping implementation method and device thereof. Background technique [0002] With the popularization and commercialization of the Internet, operators increasingly hope to classify different service types and control users' service levels more powerfully, so as to provide personalized broadband data services. One of the key technologies for realizing these differentiated services (Quality of Service, QOS) is traffic shaping. Traffic shaping can shape the user's irregular traffic or the traffic that does not conform to the predetermined traffic characteristics, so as to make the user's traffic smoother and facilitate the bandwidth matching between the upstream and downstream of the network. Compared with other bandwidth control methods, traffic shaping needs to temporarily cache user traffic exceeding the pre...
