Description

Configuration method and system for optical layer service layered model in network management system

Technical Field

The invention relates to the technical field of computer communication, in particular to a configuration method and a system of an optical layer service hierarchical model in a network management system.

Background

With the rapid development of optical fiber communication technology, the early WDM (Wavelength Division Multiplexing) technology changes the ultra-low utilization of only transmitting one Wavelength channel in one optical fiber, and makes full use of the huge bandwidth resource (low-loss band) of the optical fiber, so that the transmission capacity of one optical fiber is increased by several times to dozens of times compared with single Wavelength transmission, thereby increasing the transmission capacity of the optical fiber, reducing the cost, and having great application value and economic value. However, with the increasingly wide and complex application scenarios, in order to solve the problems of no wavelength, poor sub-wavelength service scheduling capability, weak networking capability, and the like of the conventional WDM Network, the OTN (Optical transport Network) is completely backward compatible as a next generation backbone transport Network, and can be established on the basis of the existing SONET (Synchronous Optical Network)/SDH (Synchronous Digital hierarchy), thereby not only providing complete transparency of the existing communication protocol, but also providing end-to-end connection and networking capability for WDM, and spanning the conventional electrical domain (Digital transport) and Optical domain (analog transport), which is a unified standard for managing the electrical domain and the Optical domain. However, with the high-speed development of services, new services require larger bandwidth and lower time delay, and require a rigid and flexible transmission pipeline; the existing PTN (Packet Transport Network), OTN, MSTP (Multi-Service Transport platform) multilayer Network architecture of an operator cannot support the development of new services, and the organic fusion POTN (Packet Optical Transport Network) of PTN and OTN becomes a breach, thereby simplifying Network layers, providing larger bandwidth, reducing construction cost, and facilitating Service provisioning.

For the three communication networks WDM, OTN and POTN, the optical layer transmission can not be opened. According to the g.872, g.709 related standard of ITU-T (international Telecommunication union, Telecommunication Standardization Sector), the optical layer transmission is divided into three levels, namely: an Optical Channel (OCH) layer, an Optical Multiplexing Section (OMS) layer, and an Optical Transport Section (OTS) layer. In the current-stage network management system, the configuration of the optical layer service is not completely realized and managed according to three standard layers, so that the upper-layer comprehensive network management of telecom and other operators and a centralized controller in a novel SDN network architecture have to perform complex processing on the optical layer service data, convert the optical layer service data into a universal data structure and then perform the serial connection of the services of various manufacturers, and greatly reduce the user experience.

Therefore, a technical solution for performing automatic configuration of an optical layer service hierarchical model in a network management system in a normative and efficient manner is needed.
