摘要
在实际应用中,以IP网为基础的通用多协议标签交换(GMPLS)控制平面的可靠性尚不能满足自动交换光网络(ASON)电信级的要求,针对这一情况,文章主要探讨了GMPLS信令RSVP-TE的扩展,为建立保护光通道实现路由排除功能,对排除路由对象(XRO,ExcludeRouteObject)和显示排除路由对象(EXRS,ExplicitExcludeRouteSubobject)两个对象进行了扩展。
In practical applications, the reliability of control plane in GMPLS based on IP network couldn' t satisfy the telecom level requirements of ASON, in view of this condition ,this paper discusses extensions to RSVP-TE of GMPLS, in order to accomplish the function of excluding route when setting up a protect route, we extend two objects: Exclude Route Object (XRO) and Explicit Exclude Route Subobject (EXRS).
