摘要

在最近的一系列论文[1-3]中，我们研究了如何以经济有效的方式为交通流提供高水平的可用性和服务差异化。开发的基本思想是在网络拓扑中嵌入物理层的一组高可用性链路和节点(称为脊柱)，以支持保护和路由，提供具有不同级别的端到端可用性的不同弹性类别。在本文中，我们提出了考虑链路可用性和升级链路可用性成本的脊柱设计问题的优化模型。数值结果显示了修改网络拓扑子集的可用性以提供QoR类的优点。

Designing a high availability subnetwork to support availability differentiation

In a recent series of papers [1-3] we studied the problem of how to provide both high levels of availability and service differentiation to traffic flows in a cost efficient manner. The basic idea developed was to embed at the physical layer a high availability set of links and nodes (termed the spine) in the network topology to support protection and routing in providing differentiated classes of resilience with varying levels of end-to-end availability. In this paper, we present an optimization model formulation of the spine design problem considering link availability and the cost of upgrading link availability. Numerical results show the advantages of modifying the availability of a subset of the network topology to provide QoR classes.
