Abstract

The invention provides a bandwidth control method, a bandwidth control device and a network bridge. The invention provides a bandwidth control method based on point-to-multipoint network bridge. The method comprises the following steps that: the beacon cycle with the scheduled length is divided into a distributed coordination function cycle and a point coordination function cycle; based on the scheduled unit bandwidth, the size of the scheduled unit pocket and the point coordination function cycle, minor time slice units comprising a plurality of minor time slices are judged; in the distribution type coordination function cycle, when a registration request message of terminal access equipment is received, the number of the minor time slice units distributed for the bandwidth is calculated according to the bandwidth of the thermal access equipment, and a mark comprising the terminal access equipment and the information item of the number of the minor time slice units are written in the current registration terminal list, and a registration response message is constructed and transmitted; in the point coordination function cycle, taking the minor time slices as a unit, according to the scheduled scheduling algorithm, the terminal access equipment indicated by the mark of the terminal access equipment of each information item in the current registration terminal list is polled.

Description

technical field [0001] The present invention relates to a technique for fine-grained bandwidth control on a point-to-multipoint network bridge, and in particular to a bandwidth control method and device and a network bridge comprising the bandwidth control device, which has a point coordination function (PCF) In the PCF mode, the PCF cycle is divided into multiple small time slice groups, and the number of small time slice groups that meet the bandwidth requirements is allocated to the user terminal, and the user terminal is rotated according to the number of the small time slice groups in the PCF cycle. inquire. Background technique [0002] A point-to-multipoint (PMP) communication system is cheaper than a point-to-point (PPP) communication system, so it develops rapidly and is widely used. However, since point-to-multipoint communication can cause collisions, all technologies using point-to-multipoint must resolve collisions. [0003] The IEEE 802.3 protocol is a typica...
