【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。更多还原

【Abstract】 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).更多还原
