Burst stream processing method based on software-defined network stateful data plane

Abstract

The invention relates to a burst flow processing method based on a stateful data plane of a software-defined network. The burst flow problem that may cause network congestion is processed based on a stateful extended version of the southbound protocol OpenFlow in SDN. By adding a state table to the switch to distinguish different states of traffic, so as to adopt different routing strategies to avoid congestion.

Description

technical field [0001] The invention relates to the field of software-defined networks, in particular to a burst flow processing method based on a software-defined network with a stateful data plane. Background technique [0002] A network traffic burst refers to a sudden major change in network traffic. The network needs to handle various traffic demands from different sources, so the traffic carried in the network will not be continuous and immutable. For example, for Alibaba, Double Eleven every year is when the traffic bursts. In addition, the amount of network visits in normal times will also change with time. For example, the traffic in the second half of the night is always relatively small, and the traffic on weekends is always relatively high. The traffic will change all the time, and there will be sudden traffic problems. Traffic bursts are likely to cause network congestion, resulting in problems such as packet loss, delay, and jitter, resulting in a decline in...

AI Technical Summary

Problems solved by technology

Traffic bursts are likely to cause network congestion, resulting in problems such as packet loss, delay, and jitter, resulting in a decline in network service quality

In addition, burst traffic may also cause greater harm to the network, such as DOS attacks, etc.
