Embodiment Construction

[0082] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0083] In addition, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0084] An embodiment of the present invention provides a bandwidth allocation method for an optical burst ring network, including:

[0085] The master node obtains the current bandwidth resource, and removes the bandwidth resource occupied by the cross-master node connection from the current bandwidth resource, and obtains the bandwidth resource to be allocated;

[0086] The master no...

Abstract

The present invention provides an optical burst ring network bandwidth allocation method, comprising: a master node obtaining present bandwidth resources, eliminating the bandwidth resources of said present bandwidth resources which have already been occupied by an inter-master node connection, and obtaining bandwidth resources awaiting allocation; the master node, in accordance with a bandwidth request from each node of the optical burst ring network, allocates, to each node, the bandwidth resources awaiting allocation. The present invention additionally provides an optical burst ring network bandwidth allocation device. The present invention embodiment, by eliminating, prior to commencing bandwidth allocation, the bandwidth resources occupied by an inter-master node connection, thus solves the receiving conflict caused by inter-master node service data connectivity.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a bandwidth allocation method and device for an optical burst ring network. Background technique [0002] In order to meet the needs of future-oriented dynamically changing service traffic and efficient utilization of bandwidth resources, the industry has proposed the concept of Optical Burst Ring (OBRing) based on all-optical packet transmission and switching. OBRing can greatly reduce the cost of software, hardware, operation, maintenance and management of the existing network, and is especially suitable for fully interconnected network application scenarios where any point-to-point connection is established. [0003] OBRing can use a single-ring or dual-ring topology. Such as figure 1 As shown, as an example, four nodes A, B, C and D are connected together by a single ring. OBRing consists of a control plane and a data plane, each using different working wavelengths. F...
