Abstract

The invention discloses a wide area network flow optimization control method. The method includes: all optimal paths between nodes in a network are obtained, and the optional paths are saved in an optional path database; when it is determined that the congestion of the network occurs, data stream of all congested links is obtained, and the data stream is divided into a first type of data stream and a second type of data stream according to the priority of the data stream; and paths are selected in sequence from the optional path database for the first type of data stream and the second type of data stream. The invention also discloses a wide area network flow optimization control apparatus.

Description

technical field [0001] The invention relates to computer network flow engineering technology, in particular to a wide area network flow optimization control method and device. Background technique [0002] Traffic engineering is a network engineering technology that optimizes network traffic distribution and improves network bandwidth utilization. At present, there are many research results in this area. [0003] Traditional traffic engineering mainly calculates the optimized link weight distribution by estimating the traffic matrix. This method intends to achieve long-term optimization goals through one-time configuration; however, due to the high dynamics and unpredictability of current network traffic, this Practices often fail to achieve better results. Google applies the software-defined network (Software Defined Network, SDN) mechanism to its global data center network. According to the specific traffic characteristics of its network, it dynamically selects the path f...
