Example Embodiment

[0029] In order to solve the problem that the prior art cannot adjust the bandwidth allocation scheme in time to deal with burst traffic, the embodiments of the present invention provide a method and device for multi-frame dynamic bandwidth allocation. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0030] On the one hand, the first embodiment of the method for multi-frame dynamic bandwidth allocation of the present invention, such as figure 2 As shown, it includes the following steps:

[0031] 101. Receive a bandwidth request uploaded by each transmission container.

[0032] 102. Determine whether the bandwidth requested by the bandwidth request of the transmission container is greater than the bandwidth allocated to the transmission container in the current multi-frame dynamic bandwidth allocation period.

[0033] 103. If it is greater than, allocate the available bandwidth to the transmission container. Gen...

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 ...
