Abstract

A fault-tolerant scheme, called dual homing, is generally used in IP-based access networks to increase the survivability of the network. However, dual homing itself cannot provide survivability with respect to possible failures in the Wavelength Division Multiplexed (WDM) core network. To provide survivability in the core network, protection and restoration techniques must be used. In the past, dual homing architecture and protection are studied separately. In this paper, we observe that the dual homing architecture introduces new issues for protection and restoration design, especially when providing survivability against two independent failures, one in the access network and the other in the core network. This paper provides an integrated solution and studies the protection design problem in the WDM core network, given a dual-homing infrastructure in the access network. Several algorithmic solutions are proposed, and performance of the solutions is compared.
