随着网络中数据业务份量的加重,为了在传统SDH网络上更好地适应数据业务传送,SDH多业务平台也正逐渐从简单的支持数据业务的固定封装和透传的方式向更加灵活有效支持数据业务的下一代SDH系统演进和发展。最新的发展技术是支持链路容量调节方案(LCAS)标准。LCAS技术能灵活解决部分带宽调配问题,现在越来越多的厂家在SDH设备上提供了这些功能。运营商采用这些技术能够节约大量网络资源并保证网络正常运行。
With the increase of data traffic in the network, in order to better adapt to the data service transmission in the traditional SDH network, the SDH multi-service platform is also gradually moving from simple encapsulation and transparent transmission of data services to more flexible and efficient support The evolution and development of next generation SDH systems for data services. The latest development technology is to support the Link Capacity Adjustment Scheme (LCAS) standard. LCAS technology can flexibly solve part of the bandwidth allocation problem, and now more and more manufacturers provide these functions on SDH devices. Operators using these technologies can save a lot of network resources and ensure the normal operation of the network.
