A realization method of sdn-based gis network topology model

Abstract

A method for implementing an SDN-based GIS network topology model, involving the SDN field, in which a client requests topological resource data from the background, and converts the requested data into a self-defined topology tree model object; recursively traverses the self-defined topology tree model Object, draw each node, and add the circular cover object corresponding to the node to a collection synchronization model; if the node type is a logical domain node and has not been expanded, obtain all the node collections that need to be connected to it, and put them in the collection Draw a connection line with the unexpanded logical domain node or network element node; calculate the center of the circular covering through the longitude and latitude of the logical domain on the GIS map. The invention displays the network topology on the GIS map, conveniently manages and locates the geographical location of the network resources, effectively operates and controls the resources, and improves 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...

AI Technical Summary

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 the search. The technology is too manual, and the search leads to efficiency. low

At present, there is no set of control planes open to operators and users, which can effectively operate and control the hierarchical structure of network resources, resource ownership, and network element structure maintenance.
