Network Survivability for Multiple Probabilistic Failures

Many different types of pre-provisioned recovery schemes have been developed for IP Multi-Protocol Label Switching (MPLS) and optical Dense Wavelength Division Multiplexing (DWDM) networks. Network service recovery from multiple correlated failures is a major concern given the increased level of infrastructure vulnerability to natural disasters, massive power failures, and malicious attacks. To properly address this problem, a novel path protection solution is proposed to jointly incorporate traffic engineering and risk minimization objectives. The framework assumes probabilistic link failures and is evaluated against some existing multi-failure recovery schemes using network simulation.
