Robustness and reliability are critical issues in network management. To provide resiliency, a popular protection scheme against network failures is the simultaneous routing along multiple disjoint paths. Most previous protection and restoration schemes were designed for all-or-nothing protection and thus, overkill for data traffic. This paper, explore the Reliable Adaptive Multipath Provisioning (RAMP) problem with reliability and differential delay constraints. This paper aims to route the connections in a manner such that link failure does not shut down the entire stream but allows a continuing flow for a significant portion of the traffic along multiple not necessary disjoint paths, allowing the whole network to carry sufficient traffic even when link/node failure occurs.
