项目摘要

The Internet service subscribers, including both enterprises and general end users, expect for high availability of Internet connections from their service providers. Guarantee of end-to-end (E2E) availability for each connection in dynamic Generalized Multi-Protocol Label Switched (GMPLS) networks has been an attractive design objective. The previous research work in the related areas has focused on development of survivable routing schemes for single or dual simultaneous failures under a given type of protection. However, as the state-of-the-art communication carrier networks evolve to a multi-service bandwidth provisioning environment, the E2E availability of each LSP has become a major performance index for achieving Quality-of-Service (QoS) guarantee percieved by the end users. This fact has imposed a fundamental impact on the development of survivable routing and spare capacity allocation schemes since the end users may not care about how many simultaneous failures the carrier can handle, and what type of protection scheme the carrier adopts. Driven by the observations, this project is committed to work on a general availability-aware service provisioning architecture in GMPLS networks for both real-time and non real-time services, where the long-term and short-term E2E availability of each connection will be defined and manipulated. Based on the availability models, the corresponding enhancement on the reported survivable routing and spare capacity allocation schemes will be investigated. The proposed research is envisioned to provide a complete solution to survivable routing problems by leaving some of the previous design issues, such as "how many simultaneous failures the carrier can handle", and "what type of protection scheme we had better adopt", no longer as problems. Such survivable routing architecture is expected to better fit into the design requirements of modern communication carrier networks where service availability is the ultimate goal of redundancy investment and survivability guarantee. The project will also lead to HQP training in availability analysis and optimization techniques, which will greatly contribute to the Canadian communication industry.
互联网服务的用户,包括企业和一般的最终用户,期望从他们的服务提供商的互联网连接的高可用性。在动态通用多协议标签交换(GMPLS)网络中,保证每个连接的端到端(E2E)可用性一直是一个有吸引力的设计目标。以前的研究工作在相关领域的重点是发展的生存路由计划,单或双同时故障下的一个给定类型的保护。然而,随着现有技术的通信运营商网络向多业务带宽供应环境演进,每个LSP的E2E可用性已经成为实现终端用户感知的服务质量(QoS)保证的主要性能指标。这一事实施加了生存路由和备用容量分配方案的发展,因为最终用户可能不关心有多少同时故障的运营商可以处理,以及什么类型的保护方案的运营商采取了根本性的影响。在观察的驱动下,该项目致力于在GMPLS网络中为实时和非实时服务提供一个通用的可用性感知服务供应架构,其中每个连接的长期和短期E2E可用性将被定义和操纵。基于可用性模型,相应的增强报告的生存路由和备用容量分配方案将进行研究。拟议的研究设想提供一个完整的解决方案,生存路由问题留下一些以前的设计问题,如“有多少同时故障的运营商可以处理”,“什么类型的保护方案,我们最好采取”,不再作为问题。这种可生存的路由体系结构被期望更好地适应现代通信运营商网络的设计要求,其中服务可用性是冗余投资和生存性保证的最终目标。该项目还将导致HQP在可用性分析和优化技术方面的培训,这将大大有助于加拿大的通信行业。
