Traffic engineering for inter-domain optical networks
… the actual traffic load over the existing lightpaths continuously and reacting to the load changes by adding or tearing down lightpaths. We avoid load instability directly by setting up a lightpath when congestion occurs or by tearing down a lightpath when the congestion is relieved. For …

Scalable fault management architecture for dynamic optical networks : an information-theoretic approach
… place of electronic switching, of high data-rate lightpaths at intermediate nodes is one of the key enabling technologies for economically scalable future data networks. This replacement of electronic switching with optical switching at intermediate nodes, however, presents new challenges for …

Design and protection algorithms for path level aggregation of traffic in WDM metro optical networks
… point to point (for example, lightpaths), point to multi-point (for example, source based light-trails), multi-point to point (for example, destination based light-trails) and multi-point to multi-point (for example, light-trails); (2) incorporates heterogenous switching …

End-to-end data reliability in optical flow switching
… an all-optical data plane employing end-to-end lightpaths. Due to noise added in the transmission and detection processes, the channel has non-zero probability of bit errors that may corrupt the useful data or flows transmitted. In this thesis, we focus on the end-to-end reliable data delivery …

Green optical network design : power optimization of wide area and metropolitan area networks
… between node pairs are routed via direct, fixed lightpaths using patch panelling and unexpected, bursty traffic is switched on a standard optical bypass network. We analyze power distribution among components and find the OXC switch most scalable at each node and O/E/O switches and routers …

Optimización y planificación de redes ópticas transparentes WDM
… por medio de conexiones todo-ópticas, llamadas lightpaths. Un lightpath se origina en un transmisor óptico y termina en un receptor óptico, ocupando un único canal de longitud de onda en cada enlace atravesado. Al ser procesado electrónicamente en los nodos intermedios el tráfico cargado por el …

Investigation of performance issues affecting optical circuit and packet switched WDM networks
… networks. Slow optical switching in which lightpaths are requested, provisioned and torn down when no longer required is known as optical circuit switching (OCS). Services enabled by OCS include wavelength routing, dynamic bandwidth allocation and protection switching. With network elements …

Routing and protection issues in optical WDM mesh networks
… fast restoration for optical connections (lightpaths) clue to its ring-like structure and pre-connected back up paths before failure, as well as its ability to achieve low capacity redundancy because each straddling link on a cycle can provide double protection capacity clue to the nature …
