Generalized Multi-Protocol Label Switching (GMPLS) provides network operators with a strong tool in traffic engineering and abundant Classes of Service (CoS), and has been well recognized as the best candidate for the next generation IP-centric carrier networks. One of the most important functions supported by GMPLS is its ability in performance multilayer protection and restoration such that the End-to-End (E2E) service availability of each Label Switched Path (LSP) could be guaranteed according to the service level agreement (SLA). The previously reported studies on service availability and survivability have mostly focused on the efficiency in the redundancy allocation upon a specific protection scheme or under the consideration of a given number of simultaneous failures in networks. A general framework for survivable routing and spare capacity allocation that can best address the availability-aware design, however, has never been reported. Thus, this project is committed to solve this problem by bringing up a group of researchers and engineers, to introduce and investigate novel availability-aware survivable routing architecture under the framework of GMPLS-based recovery. Insight research and evaluation will be conducted upon the developed strategies and schemes cooperating with the proposed framework, which could be exercised in the carrier network of our industry partner - Bell Canada.

广义的多协议标签交换（GMPLS）为网络运营商提供了交通工程和丰富服务类（COS）的强大工具，并已被公认为是下一代IP中心载体网络的最佳候选人。 GMPL支持的最重要功能之一是其性能多层保护和恢复能力，因此可以根据服务级别的协议（SLA ）。先前报道的有关服务可用性和生存能力的研究主要集中在特定保护方案上的冗余分配效率上，或者在考虑到给定数量的网络中同时失败的情况下。但是，从未有过关于最能解决可用性意识设计的可生存路由和备用容量分配的一般框架。因此，该项目致力于通过提出一组研究人员和工程师来解决这一问题，以在基于GMPLS的恢复框架下介绍和调查新颖的可用性可生存的路由体系结构。洞察研究和评估将对与拟议框架合作的开发策略和计划进行，该框架可以在我们行业合作伙伴的运营商网络 - 加拿大贝尔。
