Delay scheduling-based network traffic conflict prevention method and delay scheduling-based network traffic conflict prevention system

Abstract

The invention provides a delay scheduling-based network traffic conflict prevention method and a delay scheduling-based network traffic conflict prevention system. The method includes: step 1: path performance detection is carried out on a default path within a probing cycle, and if the default path of an overlay network can meet the requirement of network transmission performance, step 2 is executed, or else step 3 is executed; step 2: traffic is transmitted via the default path; step 3: a transfer traffic calculation function is utilized to calculate transfer traffic to be transferred on the default path, and the transfer traffic is part of the traffic transmitted on the default path; step 4: path performance detection is carried out on alternate paths, the transfer traffic is allocated onto the alternate paths for transmission according to the carrying capacity of the alternate paths, and the steps are repeated in the next probing cycle. The invention solves the problem of vertical conflict in the prior art, prevents the phenomenon of frequent jitter caused by the optimization conflict problem of the conventional overlay network system, and guarantees the normal service performance of the overlay network.

Description

technical field [0001] The invention relates to the field of computer network and communication, in particular to a method and system for avoiding network traffic conflict based on hysteresis scheduling. Background technique [0002] At present, in the research of Internet service routing technology, an increasingly prominent trend is to build an overlay network (Overlay Networking) on ​​the underlying physical network to optimize the transmission of service traffic. Overlay Routing technology can effectively make up for the shortcomings of the underlying network protocol, and strive to maximize the use of bandwidth and redundant paths in the network. Overlay network nodes themselves need to maintain and establish corresponding routing table entries, and at the same time detect network conditions and find out the optimal path with better performance than that selected by the IP protocol layer. On the traditional Internet, network operators (Internet Service Providers) often...
