With the soaring channel speed and density in all-optical networks (AONs), the risk of high
data loss upon network faults increases quickly. To manage network faults efficiently, an m …

We study an approach to quality-of-service (QoS) that offers end-users the choice between
two service classes defined according to their level of transmission protection. The fully …

We present a collection of studies related to the availability of service in mesh-restorable
trans port networks. The issue of service availability in transport networks is of increasing …

Network survivability is a crucial requirement in WDM mesh networks. In this paper, we
systematically consider the problem of dynamic survivability with dynamic single link failure …

The two protection methods wrapping and steering used in IEEE 802.17 resilient packet ring
(RPR) provide fast but very inefficient and limited network failure recovery. Due to the …

A survey of recent literature on all optical networking is presented. Starting from multiplexing
techniques and topological features, network design and performance issues are reviewed …

Transparency of the optical layer offers the possibility to design a network that operates at
varying transmission bit rates. While variable bit rate interfaces are being tested and will …

The Internet is emerging as the new universal telecommunication medium. IP over WDM has
been envisioned as one of the most attractive architectures for the new Internet …

The present invention includes novel techniques, apparatus, and systems for optical WDM
communications. Tunable lasers are employed to generate respective subcarrier …
