Several emerging new applications and services, especially the ones based on massive data transmission, require capabilities non-offered by traditional Grid infrastructure. The later usually exploits packet-routed networks as non-deterministic resources. The constant evolution of optical network technologies combined with the dynamic provisioning mechanisms holds the promise to support these types of advanced applications and services. Nevertheless, the huge bandwidth offered by optical networks is still inefficiently exploited and needs appropriate killer applications. The global objective of my research program is to investigate new networking concepts and to propose innovative solutions in the context of service-oriented optical networks. I will study new architecture and protocols for the next generation of optical networks to support network and service virtualization. The emerging large scale applications require what have been referred to as "deterministic" network services that imply defined and guaranteed service-level parameters (e.g., minimum bandwidth, loss rate, latency and jitter). In addition, those services need to be provisioned across multi-domain heterogeneous networks. In order to create an optical network supporting virtualized sub-networks with different QoS-guaranteed end-to-end virtual links, I will first investigate a novel optical control plane that takes into account traffic dynamics. The aim is to provide a new intelligent control plane strategy with dynamic multi-granularity connections. The routing and bandwidth allocation for those connections will be performed under constraints: QoS guarantees interaction, computing resources and network state information availability. My new control plane will dynamically switch between high-level signaling for long-lived applications and low-level approach for finer applications granularity. My research project proposed in this application investigate three main tracks: 1) low-level signaling such as OBS (Optical Burst Switching) signaling 2) high-level signaling such as UCLP (User Controlled LightPath) and 3) multi-granularity resources optimization in service oriented optical networks to support network virtualization.
