Abstract

The invention relates to a method for graphically representing network topological objects and network topological object relationships in network planning. The logical topological structure of a physical network is represented in a topological graph drawing area in planning software by the following operation steps: 1, drawing a station and nodes; 2, drawing an optical cable between two nodes; 3, drawing an optical fiber pair on the optical fiber; 4, drawing end-to-end service connection between the two nodes; 5, drawing a shared risk link group; 6, creating linear multiplex section protection; 7, creating a ring; and 8, creating service route. In the method for graphically representing the network topological objects and network topological object relationships in network planning, the graphical representation mode is direct, simple, clear and complete, all network topological objects in an SDH / ASON network are covered basically, and thus, it is relatively easy to define a mathematic model required by the operation of the planning software on this basis, and a mathematic foundation is provided for the operation of the software.

Description

technical field

[0001] The invention relates to the logical structure of the network topological structure in software, in particular to a graphical representation method of network topological objects and their relationships in network planning. Background technique

[0002] Currently, an Automatic Switched Optical Network (ASON) that combines switching technology and optical transport technology has been recognized by the industry as the development direction of the optical transport network. As the ASON network planning service platform, ASON network planning software has been paid more and more attention by equipment manufacturers and operators, and high requirements have been put forward for this kind of software. Intuitive, clear and easy to use, etc.

[0003] In the network topology structure of a traditional SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy) network, network topology objects mainly exist in the form of protection rings, with few type...
