NeTS-NBD Collaborative Research: SOON: Service-Oriented Optical Networks

视频会议、多媒体分发、高性能科学计算等新兴的下一代互联网应用具有高带宽、多源、多目的通信模式、严格的时延和丢失服务质量要求、高可靠性和生存性要求等特点。为了支持这些不同的需求，新兴网络必须能够以灵活的方式管理资源。该项目研究了一个面向服务的光网络架构，该架构由一个能够动态和敏捷地分配资源的底层光传输网络实现。光传输层提供了资源预留的基本机制，光业务层在基本的光传输层之上构建了一套服务。在该项目中，需要解决的具体问题包括：1)研究支持光网络中多播通信服务的机制，2)研究在此类网络中提供生存能力的机制，以及3)开发支持光网络中可靠传输的方法。拟议的活动将产生一个框架和架构，用于在光网络中部署广泛的服务，以支持最苛刻的下一代应用的需求。该项目还将开发用于实现多播和提供可靠服务的新算法和协议，并将开发用于评估这些算法和协议的分析模型。拟议活动的更广泛影响是，它将为研究生提供宝贵的培训，为他们从事光网络领域的研究和工程工作做好准备。

Many emerging next-generation Internet applications, such as videoconferencing, multimedia distribution, and high-performance scientific computing, are characterized by high bandwidth requirements, multi-source and multi-destination communication paradigms, strict quality of service (QoS) requirements with respect to delay and loss, and high reliability and survivability requirements. In order to support these diverse requirements, emerging networks must be able to manage resources in a flexible manner. This project investigates a service-oriented optical network architecture that is enabled by an underlying optical transport network capable of dynamic and agile resource allocation. An optical transport layer provides the basic mechanisms for reserving resources, and an optical service layer builds a set of services over the basic optical transport layer. In the project, specific problems to be addressed include 1) investigating mechanisms for supporting manycast communication services in optical networks, 2) investigating mechanisms for providing survivability in such networks, and 3) developing methods for supporting reliable transport in optical networks. The proposed activity will result in a framework and an architecture for deploying a wide range of services in optical networks in order to support the requirements of the most demanding next-generation applications. The project will also result in the development of new algorithms and protocols for implementing manycasting and providing reliable services, and will lead to the development of analytical models for evaluating these algorithms and protocols. The broader impact of the proposed activity is that it will provide valuable training for graduate students, preparing them for careers in research and engineering in the field of optical networking.
