Distributed flow control method and system

Abstract

The invention discloses distributed flow control method and system, wherein the method comprises the following steps of: transmitting flow control information to at least one remote node by using a local node when the local node and the remote node carry out point-to-point communication; and receiving the flow control information and regulating the transmitting flow of the local node by using theremote node. When any nodes in a local area network carry out point-to-point communication, the transmitting flow of the remote node is limited under the condition of an overlarge local load, therebythe local arriving flow is effectively controlled, and the flow burst is avoided. When finding that one node in the local area network forcibly occupies the bandwidth of the local area network, any nodes in the local area network communicate with the node in time to coordinate the node for flow control so that the upstream or downstream flow is limited, thereby the entrance bandwidth of the wholelocal area network is effectively coordinated and distributed.

Description

technical field [0001] The invention belongs to the field of network flow control, and in particular relates to a distributed flow control method and system. Background technique [0002] As the network becomes more and more popular, user behaviors become more and more diverse and difficult to control, while the development of domestic network bandwidth is relatively lagging behind. More and more applications on the network occupy our bandwidth: P2P, PPlive, QQlive, Skype, etc., and even traditional web browsing applications have been seriously affected. [0003] When users use the client software to experience the network, once the network speed decreases and the traffic suddenly increases, the user experience will be greatly reduced. In fact, this situation often occurs in today's network. At this time, the user is often eager to know how many programs or applications are using the network on the currently used client software, the bandwidth occupied by these programs or ...

Problems solved by technology

[0006] However, no matter which of the above unilateral restriction methods, its flow control is based on restricting local received traffic

Its defects are as mentioned above, the main reason is that it cannot suppress the sending behavior of the remote end very well, and the sent data has already occupied the downlink channel, so as to realize the flow control quickly and effectively

[0007] At the same time, when individual nodes in the local area network consume a large amount of bandwidth, so that they occupy the resources of other nodes in the local area network, the limited bandwidth resources in the local area network cannot be distributed and effectively used

However, the existing methods based on unilateral current limiting cannot limit the bandwidth consumption of these bandwidth-occupied nodes, let alone provide a reasonable and practical mechanism to effectively allocate the ingress bandwidth of the LAN.
