Automatically switched optical network evolution system and method

Abstract

The invention discloses an automatically switched optical network evolution system and method and belongs to the automatically switched optical network field. The method includes the following steps that: a thin client end arranged in a network element initiates an application request to an application end arranged in a software defined network (SDN); the application end performs computation on the application request, and sends a processing result to the thin client end; and the thin client end translates the processing result into an instruction which can be executed by the network element, so that corresponding operation can be performed. The invention also discloses the automatically switched optical network evolution system. The automatically switched optical network evolution system and method of the invention can provide simple, efficient and safe services for users by means of an SDN architecture and a cloud computing platform.

Description

technical field [0001] The present invention relates to an Automatic Switched Optical Network, in particular to an Automatic Switched Optical Network (ASON, Automatic Switched Optical Network) based on software defined network (SDN, Software Defined Network) architecture and cloud computing platform technology evolution. Background technique [0002] ASON is generally considered in the industry as a development direction of the transport network. The development of ASON has gradually developed the transport network from a single link providing function in the past to an intelligent network platform that can meet various service requirements. [0003] While the current ASON architecture such as figure 1 As shown, each device in the network is somewhat intelligent, but very limited. They can only make passive responses based on the incoming and outgoing data streams of the node, and cannot know the dynamic status of other nodes in time. The discrete self-control of each netwo...

Problems solved by technology

Even if there is a compromise solution, it needs to install expensive hardware equipment in a fixed location

[0004] In addition, the GMPLS control plane interface of the current ASON architecture such as figure 2 As shown, the control plane is integrated with the transport plane, management is becoming more and more complex, innovation is slow, and the mobility of virtualized resources requires a more powerful, flexible and simple control plane

The workload-oriented network requires the decoupling of the control plane and the resource itself, resulting in an increasing gap between the control plane and the transmission plane, and the total cost of ownership paid by users for using the network is increasing

It is obvious that in order to cope with the increasingly large and complex ASON network and applications, the ASON hardware support provided by individual nodes needs to be continuously improved, and these expensive hardware resources will only play a role when the network changes, and their hardware resources are in vain during network stability. In other words, the more our hardware is improved, the more serious this waste will be, and the contradiction will become more and more obvious
