Abstract

The present invention provides a method, device and system for dynamic bandwidth allocation. Through the present invention, the business flow information of each quality of service QoS queue in the downlink buffer of the central office equipment and the uplink buffer of the terminal equipment is obtained; The uplink rate ratio Mds / Mus; the central office device sends TDD frame configuration information corresponding to the adjusted downlink / uplink rate ratio Mds / Mus to the terminal device, which solves the service quality of the business caused by G.fast not supporting dynamic time allocation The problem of Qos decline has achieved the effect of improving the service quality Qos of the business.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for dynamic bandwidth allocation. Background technique [0002] The copper cable access system includes a Fast Access to Subscriber Terminals (FAST for short) system and a Very High Speed ​​Digital Subscriber Line 2 (VDSL2 for short) system. Its network architecture can be divided into G.fast / xDSL distribution point unit (DPU for short) and G.fast / xDSL terminal equipment (Customer Premise Equipment, CPE for short). Among them, the G.fast / xDSL central office equipment (DPU) can provide multiple interfaces to connect with multiple terminal equipment (CPE), that is, a central office module (Fast Transceiver Unit at the Optical Network Unit, referred to as FTU-O) and A terminal module (Fast Transceiver Unit at the Remote site, referred to as FTU-R) connected (P2P architecture), such as figure 1 shown. The connection medium between the G.fast / xDSL centr...
