Abstract

Shared restoration is key to realizing the bandwidth savings offered by mesh networking. To be viable, restoration has to be effected very quickly—typically, within 50 ms after failure. However, all the known schemes involve signaling and cross-connect setups and require excessive duration times. We describe a novel restoration scheme called FASTeR that dramatically reduces restoration times by eliminating these operations. It involves a novel select-multicast feature of the cross connects and can be applied to all-optical or electrical networks. We extend the generalized multiprotocol label-switching (GMPLS) standard to support this scheme and present simulation results to evaluate the scheme and show that a small multicasting degree is sufficient in practice to achieve the bandwidth savings gained in traditional restoration schemes.
