Abstract

Both the OIF and IETF inter-domain interfaces for control plane enabled networks are based on GMPLS protocols. OIF interfaces include ITU-T/ASON specic extensions, resulting in interoperability issues. Moreover, the connection services considered by the OIF are focused on SONET/SDH, OTN (i.e., G.709)and Ethernet, but do not consider lambda services for all-optical transport networks (i.e., without O/E/O conversion) as supported by GMPLS. Previous interoperability experiences are based on implementing an ASON-GMPLS gateway at the edge nodes in order to have the same inter-domain interface between domain edges. Regarding to the LSC switching, it is addressed introducing proprietary extension to OIF interfaces allowing to request Lambda services. This paper presents a protocol-unaware solution for enabling seamless interworking based on a centralized ASON-GMPLS proxy transparent for domain edges. Experimental demonstration has been performed in the integrated NOBEL2 Pan-European control plane emulator.

基于NOBEL2多域多层控制平面仿真器的ASON-GMPLS信令互通实验演示

使能控制平面网络的OIF和IETF域间接口都基于GMPLS协议。OIF接口包括ITU-T/ASON特定的扩展，导致互操作性问题。此外，OIF考虑的连接服务主要集中在SONET/SDH, OTN(即G.709)和以太网上，但不考虑GMPLS支持的全光传输网络(即没有O/E/O转换)的lambda服务。以前的互操作性经验是基于在边缘节点上实现ASON-GMPLS网关，以便在域边缘之间具有相同的域间接口。关于LSC交换，它解决了向允许请求Lambda服务的OIF接口引入专有扩展的问题。本文提出了一种基于集中的ASON-GMPLS代理透明域边缘实现无缝互连的协议无关解决方案。在集成的NOBEL2泛欧控制平面仿真器上进行了实验验证。
