Service flow aggregation method and device

Abstract

Embodiments of the invention provide a service flow aggregation method and device. The method comprises the following steps of computing a preset attribute value and traffic of each service flow for the service flows which reach the same source and the same target within the preset time bucket; dividing the service flows with the similarity of the preset attribute values into one group to obtain a pre-divided service flow group, wherein the similarity of the preset attribute values is that the preset attribute values conform to predetermined similar conditions; and respectively carrying out service flow aggregation on each obtained pre-divided service flow group to obtain a target service flow group which is about to make a request for a forwarding path to a controller. In a service flow aggregation process provided by the embodiments of the invention, the preset attribute values of the service flows in each pre-divided service flow group are similar, so that the preset attribute values of the service flows in the target service flow group are also similar. Meanwhile, the total traffic of the service flows in the target service flow group is not greater than a preset threshold. Therefore, the proper path is subsequently distributed to the target service flow conveniently and effectively, and compared with the prior art, the effectiveness of aggregation is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a service flow aggregation method and device. Background technique [0002] SDN network (Software Defined Network, software-defined network) is a new network innovation architecture, which can realize flexible control of network traffic. When forwarding a service flow arriving at a switch in an SDN-based wireless mesh (mesh) network, the switch will request a forwarding path from the controller, and the switch forwards the service flow according to the forwarding path returned by the controller. However, when there are many requests for service flows, it will cause two problems. One is that the control overhead of the controller will increase or even stop working; the other is that each service flow is assigned a forwarding path, and the service flow is forwarded according to the assigned path. , will increase the forwarding burden of the network. In order to so...

Problems solved by technology

However, the delay or packet loss rate of the service flows in the group may not be similar, and it is difficult to find a path for the service flow group that meets the attribute value requirements such as delay or packet loss rate of each service flow in the group

[0013] It can be seen that in the prior art, the method of aggregating service flows of the same source and the same destination within a preset time period cannot guarantee the bandwidth requirements and attribute similarity requirements at the same time, which will lead to invalidation of some aggregations
