Embodiment Construction

[0083] 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.

[0084] The basic idea of ​​the present invention is mainly reflected in the adoption of hierarchical architecture, the multi-domain OTN network is divided according to intra-domain and inter-domain, and the parent SDN OTN controller is responsible for the maintenance and management of SDN OTN inter-domain network resources, and the service connection in the inter-domain part The unified scheduling and control of the SDN OTN, and notification to the sub-SDN OTN controller, completes the maintenance and management of the internal network resources of each SDN OTN domain, and the...

Abstract

The invention discloses a framework system of a grade software defined network software controller and an implementation method thereof. The framework system and the implementation method are applied in a multi-domain optical transport network (OTN); an inter-domain mapping relation of a whole network view and a physical device network is established according to whole network topologic information by a primary (SDNOTN) controller; an inter-domain mapping processing request of the whole network view and the physical device network in each domain is sent to each auxiliary SDNOTN; and the domain mapping relation of the whole network view and the physical device network is established by the auxiliary SDNOTN controllers. Grade structures of the primary SDNOTN controller and the auxiliary SDNOTN controllers are arranged in the framework system, so that the mapping relation of the multi-domain whole network view and the overall physical device network in real sense is realized, and a whole network resource optimizing algorithm is realized in the real sense, so that the problem that the inter-domain link resource conflict occurs in a cross-domain service connection signaling process can be thoroughly solved.

Description

technical field [0001] The present invention relates to the controller technology of Software Defined Networking (SDN for short) in Optical Transport Network (OTN for short), in particular to a hierarchical software-defined network controller in a multi-domain OTN network scenario Architecture system and implementation method. Background technique [0002] With the advent of the cloud network era, the industry has put forward higher requirements for the development of the Internet. How to meet the continuous growth of the number of users, business types, bandwidth requirements, etc., and how to meet the real-time and dynamic withdrawal of service traffic by users are the main problems to be solved urgently for the next-generation optical network transmission technology as the core bearer technology; it is not difficult to find out, how to User-oriented, realizing "on-demand service" and "plug and play" is the key factor to solve the above problems, and it is also the operat...
