Abstract

The invention relates to an active queue management method for a hybrid access network of a wireless local area network and a multi-service broadband network in a software-defined control device, and a corresponding software-defined control device. The method comprises the steps of acquiring a received signal strength identifier of the wireless local area network; based on the received signal strength identifier, determining a first data packet marking probability; and notifying a home gateway to reduce a sending rate of a data source at a first ratio, wherein the first ratio corresponds to the first data packet marking probability. According to the method and the device which are disclosed by the invention, congestion of the hybrid access network consisting of the wireless local area network and the multi-service broadband network can be more reliably avoided; and moreover, flexibility of active queue management also can be improved.

Description

technical field [0001] The present invention relates to the field of queue control. Specifically, the present invention relates to a method for active queue management of a hybrid access network of a wireless local area network and a multi-service broadband network in a software-defined control device and a corresponding software-defined control device. Background technique [0002] With the increasing demand for mobile applications, wireless local area network (WLAN) has developed rapidly in the past few years, and has made the traditional fixed access network into a hybrid access network combining wireless local area network and multi-service broadband network. Due to the "besteffort" nature of data transmission and insufficient network resources, it is difficult to avoid network congestion and a certain client uses too much bandwidth, that is, more than the client can reasonably allocate in the available capacity. bandwidth. This problem is especially pronounced when the...
