S-SCN系统技术方案研究

Research on Technical Scheme of S-SCN System

SPTN控制网络是SPTN网络架构必不可少的组成部分,用来承载南向接口协议报文的传送与转发。只有成功建立S-SCN通道,域控制器才能对传送设备进行管理及配置的下发。当前各个厂家的SPTN设备的带内控制通道都是基于私有协议构建的,不支持二层桥接转发,不支持异厂家设备间的控制管理网络互通,无法实现单域内异厂家设备组网。通过对设备侧S-SCN系统设计需求进行分析,提供具有优势的主控软件二层桥接方案,并完成S-SCN系统功能方案设计,使其满足现网测试和试点规划要求,在控制域内广泛深入地实现异厂家互通,并对SPTN设备的产品化和商用具有重要意义。

SPTN Signal Control Network is an indispensable part of SPTN network architecture,used to carry the transmission and forwarding of southbound interface protocol packets.Only when the S-SCN channel is successfully established can the domain controller manage and configure the delivery device.At present,the in-band control channels of the SPTN equipment of various manufacturers are built based on private protocols.They do not support Layer 2 bridge forwarding,and do not support the control and management network communication between devices of different manufacturers.It is impossible to realize the networking of devices from different manufacturers in a single domain.By analyzing the design requirements of the S-SCN system on the device side,it provides a two-layer bridging solution of the main control software with advantages,and completes the design of the functional scheme of the S-SCN system,so that it can meet the requirements of live network testing and pilot planning in the control domain.The in-depth realization of interoperability between different manufacturers is of great significance to the commercialization and commercialization of SPTN equipment.
