FIND: Service-Centric End-to-End Abstractions in Network Architectures

提案编号：0626690PI：Tilman Wolf Institution：马萨诸塞大学Amherst标题：Nets-Find：网络体系结构中以服务为中心的端到端抽象摘要下一代网络体系结构受灵活性需求的支配。不同的终端系统、新颖的通信抽象以及安全和可管理性挑战要求网络提供广泛的服务，这些服务超越了当今互联网的简单存储转发功能。该项目为网络中的信息传输和数据服务引入了新的抽象，以克服当前网络设计的限制。通信和处理的明确分离允许各种信息传输模式的组合，这些模式扩展了网络的能力以应对其下一代挑战。目标是基于信息的传输而不是发送数据的过程来开发通信抽象。处理信息的数据表示、传输和存储由路由器上实现的服务执行。该项目的目标和预期结果是：第一，我们开发和原型适合下一代网络体系结构需求的抽象；第二，我们探索如何由终端系统指定服务，将其映射到网络中的资源，并在其运行过程中进行控制；第三，我们应用所提出的抽象来探索超越存储转发网络的新的网络范例。我们还寻求将该项目中提出的想法与开发下一代互联网的其他努力结合起来，从而增强整体影响。

Proposal Number: 0626690PI: Tilman WolfInstitution: University of Massachusetts AmherstTitle: NeTS-FIND: Service-Centric End-to-end Abstractions in Network ArchitecturesAbstractNext-generation network architectures are governed by the need for flexibility. Heterogeneous end-systems, novel communication abstractions, and security and manageability challenges require networks to provide a broad range of services that go beyond the simple store-and-forward capabilities of today's Internet. This project introduces new abstractions for information transfer and data services in the network to overcome the constraints of current network design. The explicit separation of communication and processing allows the composition of a variety of information transfer patterns that expand the capabilities of the network to meet its next-generation challenges. The goal is to develop communication abstractions based on the transfer of information rather than the process of sending data. Handling data representation, transfer, and storage of information is performed by services implemented on routers. The objectives and expected results of this project are: first, we develop and prototype suitable abstractions that meet the needs of next-generation network architectures; second, we explore how services can be specified by end-systems, mapped to resources inside the network, and controlled during their operation; third, we apply the proposed abstractions to explore novel networking paradigms that go beyond store-and-forward networking. We also seek to integrate the ideas developed in this project with other efforts to develop a next-generation Internet and thus enhance the overall impact.
