Abstract

The invention discloses a method and system for modeling an optical transmission network. The method includes: establishing end node pairs according to service requirements; and selecting network resources that meet service opening requirements between the end node pairs to form atomic routes, wherein the atomic Routing represents the network capabilities concerned when opening services between end node pairs; determine the access capabilities of atomic routes according to the access capabilities of related network elements at both ends of atomic routes; use atomic routes and corresponding access capabilities to form a service capability view , in order to model the corresponding optical transport network topology. The present invention abstracts complex OTN network resources into logical atomic routes and related access capabilities, and combines them to form a logical service capability view. When performing service provisioning on the service capability view, only the end nodes and atomic routes need to be faced , does not need to face complex actual networks, and can improve the efficiency of service provisioning.

Description

technical field [0001] The invention relates to the field of transmission network operation support systems, in particular to an optical transmission network modeling method and system. Background technique [0002] In actual network operation, provisioning of service circuits is an important work content. At present, when opening a service circuit, it is mainly to find and design a suitable service circuit route in the actual network topology and resource system, and then configure and activate the designed service circuit route. Due to the complexity of the Optical Transport Network (OTN), it is necessary to face many network elements when designing service circuits, including network elements, ports, topological connections, cross-connects, optical cables, etc. A lot of time, long service provisioning cycle, and low efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is that the topology of the existing optical tr...
