Method and apparatus for allocating multi-frame dynamic band width

Abstract

The invention discloses a method and a device for processing abrupt flow rate under the condition of multi-frame dynamic bandwidth allocation, which belong to the communication field and are invented for solving the problem of the prior art that the abrupt flow rate of a mobile terminal can not be responded. The method provided by the embodiment of the invention comprises the steps that a bandwidth request uploaded by a transmission container is received; whether the requested bandwidth of the bandwidth request of the transmission container is larger than the bandwidth allocated to the transmission container by the present multi-frame dynamic bandwidth allocation period is judged; invokable bandwidth is allocated to the transmission container if the the requested bandwidth is larger than the bandwidth allocated to the transmission container; adjusted bandwidth allocating information is sent to the transmission container. The method and the device are suitable for various point-to-multipoint communication systems.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for multi-frame dynamic bandwidth allocation in a passive optical network. Background technique [0002] In a point-to-multipoint communication system, the same central office device is connected to multiple terminal devices, thus sharing the same communication medium. Gigabit passive optical network is based on this communication architecture, and its basic structure is as follows: figure 1 As shown, it includes 3 parts: Optical Line Termination (OLT, Optical Line Termination), Optical Distribution Network (ODN, Optical Distribution Network) and Optical Network Unit (ONU, Optical Network Unit). The optical line terminal OLT is placed at the central office, providing the interface between the network side and the core network for the access network, providing an interface with the optical splitter on the ODN side, and connecting with each optical network unit ONU ...

Problems solved by technology

In this way, when there is a burst of traffic in the terminal device and the central office device needs to allocate bandwidth to it in time, due to the inherent slow processing speed and large delay of this method, it is easy to cause the central office device to fail to process the traffic of the terminal device in time. Burst traffic problem, causing data overflow of end devices

This will have a great impact on the entire DBA system
