Abstract

The embodiment of the invention provides a method and controller for traffic engineering (TE) in a communication network. The communication network comprises a controller and a plurality of nodes, wherein the plurality of nodes include flexible nodes and non-flexible nodes, the flexible nodes are directly connected with the controller, and the non-flexible nodes are indirectly connected with the controller. The method comprises the following steps: the controller determines at least one sampling node from the flexible nodes and a time frequency of traffic sampling, notifies the at least one sampling node to perform traffic sampling at the time frequency, and receives the traffic sampling data acquired by all sampling nodes during each sampling; the controller determines the parameter information required for the TE according to the traffic sampling data acquired during each sampling and the total traffic information of links of which the link utilization ratio is greater than a first preset value or smaller than a second preset value in the communication network; and the controller controls the TE according to the parameter information. According to the method and controller provided by the embodiment of the invention, the TE control under limited sampling can be realized.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and controller for traffic engineering in a communication network. Background technique [0002] Network traffic engineering (Traffic Engineering, TE) is a method to control network traffic to achieve certain specific goals of network integrity, such as optimizing network utilization, balancing network utilization, reducing network congestion, and reducing network load. technology. [0003] To achieve this overall goal of the network, the most common implementation method of TE is to first estimate (or count) the connection requirements of all sources and destinations in the entire network, and further use various routing mechanisms (or network protocols), according to TE objectives are optimized. As the scale of the network grows day by day, the computational complexity of the original TE method is huge, and the feasibility of performing all the steps of the TE is very low. ...
