Problems solved by technology

[0005] The traditional network shaping algorithm only supports distributed configuration. If the network scale is large, the configuration will be very cumbersome and complicated. The shaping algorithm is only based on a certain switch and cannot implement an end-to-end shaping strategy.

Abstract

The present invention provides an SDN-based whole-network shaping method, device, and system, wherein the method includes: the controller presets a SDN-based whole-network shaping algorithm configuration task sequence, and the task sequence includes a shaping default configuration table and a shaping dynamic table; When the controller receives the user packet reported by the switch, it obtains the source IP address and destination IP address, calculates the forwarding path of the packet according to the destination IP address, and according to the source IP address, destination IP Type and bandwidth to generate a dynamic entry in the shaping dynamic table; the controller determines the shaping bandwidth according to the shaping type and bandwidth in the dynamic entry, and adds the forwarding path and shaping bandwidth to the flow table and sends it to the switch. The invention can control the shaping algorithm of the whole network, and can provide an end-to-end shaping strategy.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data communication, and in particular to an SDN (Software Defined Network, software defined network)-based whole network shaping method, device and system. Background technique [0002] Traffic shaping (Traffic Shaping) is a measure to actively adjust the output rate of traffic, which limits the traffic and burst of a certain connection out of a certain network, so that such packets are sent out at a relatively uniform speed. Traffic shaping is usually implemented using buffers and token buckets. When packets are sent too fast, they are buffered in the buffer first, and then the buffered packets are sent evenly under the control of the token bucket. [0003] The traffic shaping of traditional switches shapes the ingress burst traffic according to the egress bandwidth of the switch. The whole process is as follows: figure 1 Shown: After receiving the burst traffic from the client...
