ABSTRACT NCR-9730105 Hui Zhang Carnegie Mellon University Rick Wilder and Chuck Song MCI Joint with NCR-9730104 Edward W. Knightly Rice University Joint with NCR-9730103 Jorg Liebeherr Polytechnic University Integrated Resource Management for the Integrated Services Internet The IETF has defined several key components for enabling an integrated services Internet: (1) service classes, which define the service models for supporting end-to-end per-flow QoS, (2) a link sharing model, which defines how different organizational entities (agencies) can share the same physical resources, and (3) a resource reservation protocol, which provides the signaling mechanisms to support these services. While these capabilities are indeed revolutionary as compared to the current Internet, serious impediments remain to achieving the vision of a ubiquitous multi-service Internet. In particular, efficient resource management algorithms must be available that actually deliver these services to the applications. Packet scheduling algorithms must be devised that can meet the service requirements of heterogeneous applications and different agencies while, at the same time, exploiting statistical multiplexing; admission control algorithms must be designed to allocate the minimum amount of network resources without violating any of the service requirements. At present, no set of resource management algorithms is available that can provide multi-service capabilities while considering the complex dynamics among connections, services, and agencies. This project will provide the first truly integrated resource management infrastructure for multi-service networks. Taking a new and comprehensive approach at resource management algorithms within the framework of the integrated services Internet, we propose to develop: (1) A novel hierarchical link sharing service model and algorithm that simultaneously supports all of the services proposed by the IETF without sacrificing efficient utilization of network resources, (2) Traffic control and scheduling algorithms that are amenable to efficient implementation in high speed and scalable switching systems, (3) Admission control algorithms for an enforceable controlled-load service with statistical quality of service guarantees, (4) Robust admission control algorithms for measurement-based controlled-load services, and (5) Traffic control algorithms that provide graceful quality-of-service adaptation in the presence of transient fluctuations of the network load. This project will develop the theoretical underpinnings of integrated resource management algorithms for multi-service networks. Moreover, in a collaboration that involves an integrated services network provider (MCI Telecommunications), a network equipment vendor (Ascend), and academic researchers (CMU, Rice, Polytechnic), the PIs will build a complete prototype implementation of the proposed algorithms on the vBNS national network infrastructure. This reference implementation will provide a first-of-its-kind platform for experimental research on the integrated services Internet that will yield critical input to both practitioners in the field and standards bodies on the effectiveness of current and newly proposed resource management algorithms.

摘要9730105许慧张卡内基梅隆大学Rick Wilder和Chuck Song MCI与NCR-9730104 Edward W.奈特莱斯大学联合与NCR-9730103 Jorg Liebeherr理工大学为综合服务因特网进行综合资源管理IETF定义了用于实现综合服务因特网的几个关键组件：(1)服务类，其定义了用于支持端到端每流服务质量的服务模型；(2)链路共享模型，其定义了不同组织实体(代理)如何共享相同的物理资源；以及(3)资源预留协议，其提供了信令机制来支持这些服务。虽然与当前的互联网相比，这些功能确实是革命性的，但实现无所不在的多服务互联网的愿景仍然存在严重的障碍。特别是，必须提供有效的资源管理算法，以便将这些服务实际交付给应用程序。分组调度算法必须能够满足不同应用和不同代理的服务需求，同时利用统计复用；接纳控制算法必须被设计成在不违反任何服务要求的情况下分配最少量的网络资源。目前，还没有一套资源管理算法能够在考虑连接、服务和代理之间的复杂动态的情况下提供多服务能力。该项目将为多业务网络提供第一个真正的综合资源管理基础设施。在综合业务互联网的框架内，我们对资源管理算法采取了一种新的和全面的方法：(1)一种新的分层链路共享服务模型和算法，它同时支持IETF提出的所有服务，而不牺牲网络资源的有效利用；(2)能够在高速和可扩展的交换系统中高效实现的流量控制和调度算法；(3)具有统计服务质量保证的可执行的可控负载服务的接纳控制算法；(4)基于测量的可控负载服务的健壮接纳控制算法，以及(5)流量控制算法，其在存在网络负载的瞬时波动时提供优雅的服务质量自适应。该项目将发展多业务网络综合资源管理算法的理论基础。此外，在涉及综合服务网络提供商(MCI电信)、网络设备供应商(Ascend)和学术研究人员(CMU、莱斯、理工学院)的合作中，私人投资机构将在vBNS国家网络基础设施上建立拟议算法的完整原型实施。这一参考实施将为综合服务因特网的实验研究提供一个首创的平台，将为外地从业人员和标准机构提供关于当前和新提议的资源管理算法的有效性的关键投入。
