Simulation method and system for power communication POTN optical transmission network

Abstract

The invention provides a simulation method and system for a power communication POTN optical transmission network. The invention is reasonable in design, is safe and reliable, improves the accident handling capability of operation and maintenance personnel, and guarantees the safe and stable operation of an electric power communication network. The method comprises the following steps: acquiring a fault equipment node and a fault optical fiber which need to be simulated, and setting the state attributes of a corresponding equipment node object and an optical fiber object in a pre-constructed POTN model as faults; sequentially checking whether the optical fibers influenced by the faults are protected or not, and extracting services influenced by the faults in the network topology in the POTN optical transmission network model; executing protection switching according to a protection strategy configured in the network topology in the POTN optical transmission network model according to the service level from high to low; and if the protection switching is executed successfully, updating an associated service channel path, otherwise, reporting service transmission interruption, and returning a fault analysis result to complete simulation.

Description

technical field [0001] The invention relates to the technical field of electric power communication, in particular to a simulation method and system for POTN optical transmission network of electric power communication. Background technique [0002] In recent years, with the development of the information industry, the type of business has gradually transformed into a diversified trend. It is no longer a simple voice service. The aggregate service of various services has become the mainstream service today, and network traffic is no longer limited to TDM services. Or group business. At the same time, it is difficult for the existing transport network to take into account the two aspects of high-capacity service transmission and efficient processing of packet services. Packet Transport Network (POTN) is a transport network that deeply integrates packet transport and optical transport technologies. It is based on a unified packet switching platform and can support both L2 swi...
