Problems solved by technology

[0003] Due to the large number of SPTN equipment and its network resources, the number of network elements in the actual physical field is huge, and the distribution is uneven. It is quite inconvenient to manage and locate the geographical location of network resources, which brings certain difficulties to t

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0019] First, the network topology model of SDN is introduced. All network resources are distributed in a tree structure. The uppermost layer is an SC-controller node, that is, the top-level SC, and multiple SC-controllers are distributed under it. Under one SC-controller, there may be multiple DC-controllers. Below the DC-controller are network elements, and the SC-controller does not directly manage network elements. The present invention displays the network topology model of SDN through the GIS map.

[0020] Such as figure 1 As shown, the SDN-based GIS network topology model implementation method of the present invention specifically includes the following steps:

[0021] S1. The client sends a request to the background through the HttpClient of the RESTful architecture, and requests the data of the topology resource to the background i...

Abstract

The invention discloses an SDN GIS network topology model implementation method, and relates to the SDN field. The method comprises the steps: enabling a client to request a background for the data of topology resources, and converting the requested data into a customized topological tree shaped model object; carrying out the recursive traversal of the customized topological tree shaped model object, drawing each node, adding circular cover objects corresponding to the nodes to a set synchronization model; obtaining a set of all nodes which need to be connected if the nodes are logic domain nodes and are not expanded, and enabling the unexpanded logic domain nodes or network element nodes in the set to be connected with the nodes; and calculating the centers of the circular cover objects through the longitude and latitude of a logic domain on a GIS map. The method displays the network topology on the GIS map, facilitates the management and positioning of the geographic positions of network resources, achieves the effective operation and control of the resources, and improves the efficiency.

Description

technical field [0001] The invention relates to the field of SDN, in particular to a method for realizing an SDN-based GIS network topology model. Background technique [0002] PTN (Packet Transport Network, Packet Transport Network) complies with the evolution of telecommunication services from voice to data migration, and has been widely deployed and applied all over the world. China Mobile advocated and supported the development of the entire PTN industry, and led the completion of the standardization of PTN. SPTN (Super Packet Transport Network) is the next-generation evolution of PTN. It uses the SDN (Software Defined Network, software-defined network) architecture for the PTN network, and combines the centralized intelligent control of SDN with the efficient multi-service transmission capability of PTN for data optimization. , Carrier-class high reliability, and end-to-end QoS guarantee combined with a new network system. [0003] Due to the large number of SPTN equi...
