Method for achieving dynamic allocation of resources of asynchronism optical packet switching network

Abstract

A method for achieving dynamic allocation of resources of an asynchronism optical packet switching network is characterized by comprising the following methods that A, a network node transmits local status information to a management plane; B, the management plane conducts whole network status assessment according to the local status information of the network node; C, the management plane redetermines resource allocation strategies according to an assessment result; D, corresponding resource allocation information is obtained according to the resource allocation strategies; E, the resource allocation information is allocated into frames and sent to the network node; F, the network node conducts local resource allocation according to the resource allocation information frames, and then feeds improved status information back to the management plane again, and closed-loop control is achieved. The method for achieving dynamic allocation of the resources of the asynchronism optical packet switching network enhances the ability of the network to solve various resource allocation problems; after the node is improved through resource allocation information, the node feeds the improved status information back to the management plane again, and closed-loop control is achieved.

Description

technical field [0001] The invention belongs to the field of asynchronous optical packet switching network, and in particular relates to a method for realizing dynamic configuration of asynchronous optical packet switching network resources. Background technique [0002] Asynchronous Optical Packet Switching (AOPS) network is the development direction of high-speed and large-capacity optical communication network in the future. Electro-optic conversion. At present, most of the research on optical packet switching network focuses on the research and analysis of network nodes and each unit technology, and there are few researches on AOPS network resource allocation. [0003] The current research on AOPS, firstly, for the transmitted status information, most of the alarm information at the transmission node is reported to the management plane, that is, when the node has an alarm, it will be reported to the management plane, and for the load status information of the transmissi...

Problems solved by technology

[0003] The current research on AOPS, firstly, for the transmitted status information, most of the alarm information at the transmission node is reported to the management plane, that is, when the node has an alarm, it will be reported to the management plane, and for the load status information of the transmission node, It will not be transmitted to the management plane, that is, the status information of each node cannot be obtained from the perspective of the entire network, so that resource allocation to nodes cannot be realized

Second, at present, there is not much research on some problems that may occur in the load, but in the actual operation of AOPS, a large amount of different ty
