Embodiment Construction

[0090] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0091] The optical burst ring network has a master node and one or more slave nodes. The master node is responsible for dynamic bandwidth allocation according to the collected bandwidth requests of each node including itself. In the optical burst ring network, in the system initialization stage, the system administrator configures the number of fixed bandwidth bytes and the load length of each time slot for each node pair on the master node, and the system will request the bandwidth in bytes, Convert to bandwidth requests in units of slots, and assign corresponding slots to each node pair.

Abstract

The invention discloses an optical burst ring network dynamic bandwidth allocation method and apparatus. The method comprises the following steps: in an optical burst ring network, according to an externally input bandwidth request about each node pair, generating a fixed bandwidth request, a guarantee bandwidth request and a non-guarantee bandwidth request, which take bytes as a unit, of each node pair, and respectively converting the fixed bandwidth request, the guarantee bandwidth request and the non-guarantee bandwidth request, which take the byte as the unit, of each node pair into a fixed time slot request, a guarantee time slot request and a non-guarantee time slot request which take time slots as a unit; through scheduling the non-guarantee time slot request of each node pair, determining a non-guarantee time slot request actually participating in non-guarantee time slot distribution; and according to the fixed time slot request, the guarantee time slot request and the non-guarantee time slot request actually participating in the non-guarantee time slot distribution, distributing fixed time slots, guarantee time slots and non-guarantee time slots to each node pair, and according to the fixed time slot, the guarantee time slot and the non-guarantee time slot which are distributed to each node pair, generating a bandwidth map.

Description

technical field [0001] The invention relates to a sub-wavelength all-optical switching network, in particular to a dynamic bandwidth allocation method and device for an optical burst ring network. Background technique [0002] The rapid growth of data services worldwide has put forward higher requirements on the transmission capacity of the core backbone network. With the further maturity of dense wavelength division multiplexing technology, the bandwidth on a single fiber is getting larger and larger. Compared with the bandwidth of a single fiber, the existing packet switching speed based on electrical processing is very low. In order to improve the switching speed and bandwidth utilization, optical packet switching is an inevitable development direction. However, due to the immaturity of the optical buffering technology, the store-and-forward mechanism cannot be adopted in the all-optical domain, which makes it difficult to realize all-optical packet switching, and it is ...
