p-cycles represent a new strategy for network restoration. Their main feature is that they
retain ring-like switching characteristics but, under appropriate design optimization, yield …

Current means of providing loop-back recovery, which is widely used in SONET, rely on ring
topologies, or on overlaying logical ring topologies upon physical meshes. Loop-back is …

From the Publisher: A leading-edge reference, this collection of original chapters from
prominent experts in the field brings you a superb presentation of the latest in …

In a self-organizing system, behavior emerges at the large scale from the collective
interaction of simple rules that apply at the smaller scale. The behavior that emerges is not …

Link recovery in high-speed four-fiber networks can be achieved using dynamic searches,
covers of rings, or generalized loopback. We present a method to provide link recovery for …

This work is motivated by interest in restorable mesh architectures for WDM optical
networking DWDM technology is expected to create an extremely modular capacity …

We study the relationship between failure localization and the properties of link restoration
algorithms, employing a quantitative measure of a network's ability to recover from two-link …

This article discusses a design of the ring-chain architecture with dual homing survivability
for metropolitan telecommunication networks. A self-healing ring (SHR) and multiple chains …

Pre-configuration of spare capacity is a new idea for the design of mesh-restorable transport
networks. Heretofore, mesh-restorable networks have always held spare capacity in an …

We introduce a new mechanism to provide multi-failure survivability based on p-cycles. This
mechanism called MFS (multifailure survivability scheme) consists of two stages: off-line …
