WDM and SDM in Future Optical Networks
White Paper To meet these demands, optical techniques are being introduced in public networks but on a link-to-link basis. This paper addresses future networks that will be to a large extent all-optical. It is prompted by the fact that both SDM and WDM are... [18 Jul 2008]
Dynamic Routing in Translucent WDM Optical Networks: The Intra-Domain Case
White Paper Translucent WDM optical networks use sparse placement of regenerators to overcome physical impairments and wavelength contention introduced by fully transparent networks, and achieve a performance close to fully opaque networks at a much less cost. [18 Jul 2008]
Effectiveness of Shared Risk Link Group Auto-Discovery in Optical Networks
White Paper This paper evaluates location-based methods for the auto-discovery of SRLGs, guided by the topology and design of AT&T's next generation transport network. Shared Risk Link Groups (SRLGs), introduced in, provide inputs necessary to plan for... [18 Jul 2008]
Improving Restoration Success in Mesh Optical Networks
White Paper However, even when the network contains sufficient capacity, the restoration paths could be blocked for two different reasons: with distributed restoration path selection schemes, multiple restoration paths may compete for the capacity of the same... [18 Jul 2008]
A Distributed QoS Network Scheduler
White Paper The Distributed QoS Network Scheduler (DQNS) is used to schedule paths over a mobile, IP or optical network. The scheduler is intelligent enough to adapt to the ever-changing network conditions and aims to serve the path requests based on a cost... [17 Jul 2008]
