Fiber optic communication network reliability assessment method

Abstract

The invention discloses a fiber optic communication network reliability assessment method. The reliability of a fiber optic communication network is assessed mainly by combining a network topology structure and service networking to establish a reliability assessment index system and an assessment model to provide reference for the reconstruction and improvement of a conventional network, the planning and construction of a new network and the designing of a re-protection scheme. The technical scheme provided by the invention is that: the method is implemented by the reliability assessment index system part and the reliability assessment model part. The reliability assessment index system is mainly based on three aspects, wherein the first aspect is a graph theory-based reliability assessment index mainly used for the reconstruction and improvement of the conventional network and the planning and construction of the new network; the second aspect is a service-based reliability assessment index mainly used for the designing of the re-protection scheme; and the third aspect is a fiber optic communication network reliability real-time measurement index mainly used for the real-time assessment of the reliability of a fiber optic communication network. The reliability assessment model is divided into a chain-like system model and a grid system model, can perform reliability assessment on the fiber optic communication network of any scale, and simultaneously is applied to the reliability assessment of an intelligent optical network.

Description

technical field [0001] The invention relates to a method for evaluating the reliability of an optical fiber communication network, which mainly establishes a reliability evaluation index system and an evaluation model combining network topology and business networking to evaluate the reliability of the optical fiber communication network. Background technique [0002] Since the advent of optical fiber communication, it has brought a revolution to the entire communication field, which makes high-speed, large-capacity communication possible. Optical fiber communication is favored due to its advantages such as low loss, wide transmission frequency, large capacity, light weight, anti-electromagnetic interference, and not easy to crosstalk. 10,000 kilometers, and the optical fiber communication network is developing in the direction of intelligence. As an information infrastructure, the reliability of the optical fiber transmission network directly affects the normal operation o...

Problems solved by technology

[0003] Due to the limitations of technical conditions and network construction ideas, the current optical fiber communication network can only reflect the operation of the network through some simple indicators (such as bit error rate, failure rate, pass rate, etc.), and there is no scientific and reasonable set of indicators. Therefore, it is urgent to study the reliability evaluation method of optical fiber communication network to provide a reliable basis for optical fiber communication network. laying the groundwork for sexual enhancement
