Title: BANDWIDTH ALLOCATION METHOD AND DEVICE FOR REALIZING BANDWIDTH ALLOCATION
Abstract:
The embodiments of the present invention relate to a bandwidth allocation method and a device for realizing bandwidth allocation, wherein the method includes: a distribution module transmits the obtained source address, destination address and bandwidth request information of a Transmission Container (TC) frame in each data frame to a Dynamic Bandwidth Allocation (DBA) subsystem corresponding to the source address; if determining that the DBA subsystem corresponding to the source address is not the same as the DBA subsystem corresponding to the destination address, the DBA subsystem corresponding to the source address reports the source address, the destination address and the bandwidth request information to a cross-domain allocation module, and then the cross-domain allocation module transmits the source address, the destination address and the bandwidth request information to the DBA subsystem corresponding to the destination address; the DBA subsystem corresponding to the destination address performs, according to the received bandwidth request information, bandwidth allocation processing for the TC frame to obtain bandwidth allocation information, and forwards the bandwidth allocation information to the DBA subsystem corresponding to the source address via the cross-domain allocation module, so that the DBA subsystem corresponding to the source address calculates and transmits the bandwidth allocation information corresponding to the TC frame in the data frame.
