Architectures and algorithms for service oriented optical networks

一些新兴的应用和服务，特别是那些基于大规模数据传输的应用和服务，需要传统网格基础设施无法提供的功能。后者通常利用包路由网络作为非确定性资源。光网络技术的不断发展与动态配置机制相结合，有望支持这些类型的高级应用和服务。然而，光网络提供的巨大带宽仍然没有得到有效利用，需要适当的杀手级应用。我的研究项目的全球目标是研究新的网络概念，并在面向服务的光网络的背景下提出创新的解决方案。我将研究下一代光网络的新架构和协议，以支持网络和服务虚拟化。新兴的大规模应用需要所谓的“确定性”网络服务，其意味着定义和保证的服务级别参数（例如，最小带宽、丢失率、等待时间和抖动）。此外，这些服务需要跨多域异构网络进行调配。为了创建一个光网络支持虚拟化子网不同的QoS保证的端到端虚拟链路，我将首先研究一种新的光控制平面，考虑到流量动态。其目的是提供一种新的智能控制平面策略与动态多粒度连接。这些连接的路由和带宽分配将在约束条件下执行：QoS保证交互，计算资源和网络状态信息可用性。我的新控制平面将在用于长期应用的高级信令和用于更精细应用粒度的低级方法之间动态切换。本课题主要研究三个方面的内容：1）光突发交换（OBS，Optical Burst Switching）等底层信令; 2）用户控制光路（UCLP，User Controlled LightPath）等高层信令; 3）支持网络虚拟化的面向业务的光网络多粒度资源优化。

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.
