Abstract— In this paper we consider the problem of provisioning spare capacity in two-layer backbone networks using shared backup path protection. First, two spare capacity alloc...
Under the hypothesis of single failures in the network, some backup paths cannot be active at the same time because they protect against the failure of different components. Hence...

— This paper presents new algorithms for dynamic routing of restorable bandwidth guaranteed paths. Dynamic routing implies routing of requests that arrive one-by-one with no a pr...
— Network survivability is a crucial requirement in high-speed optical networks. Typical approaches of providing survivability have considered the failure of a single component s...
Abstract— In order to provide reliable connections across metropolitan and wide-area optical networks, the network operator must provide some degree of redundancy so that traffic...
Abstract— This paper studies the problem of designing survivable optical wavelength division multiplexed (WDM) networks. A wavelength-routed wide area backbone network supporting...
Overlays have been proposed as a means to improve application performance in many areas, including multimedia streaming and content distribution. Some overlays use parallel transm...

Many interesting applications using mobile ad-hoc networks are possible if quality-of-service (QoS) can be effectively supported. Towards that end, this paper proposes a method ba...
Abstract— In label-switched networks such as MPLS, protection routing involves computing and setting up the backup paths at the same time when the primary paths are routed. It ha...
—Failure recovery in IP networks is critical to high quality service provisioning. The main challenge is how to achieve fast recovery without introducing high complexity and reso...
