Abstract
In one embodiment, certain SRLGs associated with members of a bundle are deemed to be 'risk-free SRLGs', i.e., SRLGs whose failure may not substantially impact the capacity of the bundle to carry traffic in a computer network. In a bandwidth unaware embodiment a number of active members of the bundle is identified for each SRLG, and a bandwidth aware embodiment further specifies an available bandwidth capacity for each SRLG to determine risk-free SRLGs. A backup path or tunnel may be established and utilized to protect a communication link as long as the SRLGs shared are deemed to be risk-free SRLGs.
