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.

通用多协议标签交换（GMPLS）为网络运营商提供了强大的流量工程工具和丰富的服务等级（CoS），被公认为下一代以IP为中心的运营商网络的最佳选择。GMPLS支持的最重要的功能之一是其性能多层保护和恢复能力，使得每个标签交换路径（LSP）的端到端（E2 E）服务可用性可以根据服务水平协议（SLA）来保证。以前报道的研究服务的可用性和生存性主要集中在一个特定的保护方案后，或考虑在网络中的同时故障的给定数量的冗余分配的效率。一个生存路由和备用容量分配的一般框架，可以最好地解决可用性感知的设计，但是，从来没有报道。因此，本项目致力于解决这个问题，通过培养一批研究人员和工程师，介绍和研究新的可用性感知的生存路由架构下的框架，基于GMPLS的恢复。将对与拟议框架合作制定的战略和方案进行深入研究和评估，这些战略和方案可以在我们的行业合作伙伴-加拿大贝尔的运营商网络中实施。
