NeTS-FIND: Recursive Network Architecture (RNA)

提案编号：0626788PI：Joseph Touch Institution：南加州大学标题：Nets-Find：递归网络体系结构(RNA)摘要递归网络体系结构(RNA)为协议栈的不同层重复使用单个灵活的协议。在传统堆栈中，协议层通过各自提供的不同服务来区分。RNA允许协议堆栈在运行时进行调整，这允许更动态地组合服务，无论是在堆栈内部还是在各个跃点的堆栈形成整体网络体系结构的方式上都是如此。RNA扩展了DARPA/NSF X-bone研究中出现的多域通信模型(MCDM)。RNA的方法认识到各种作用域和层上的端点之间的服务价值、不同层上的服务原语的相似性、“真实”和“虚拟”服务层之间的相似性，以及协议是由它们的端点的位置和它们的服务定义的。在第一年，RNA项目将专注于元协议结构的设计，并开发其服务的子集和初步的堆栈管理器。RNA将探索单个网络堆栈如何支持不同的环境，并可能通过更有用的层间协调影响更灵活的堆栈的设计。结果将在会议和出版物上公布，并将在网上提供代码。

Proposal Number: 0626788PI: Joseph Touch Institution: University of Southern CaliforniaTitle: NeTS-FIND: Recursive Network Architecture (RNA)Abstract The Recursive Network Architecture (RNA) reuses a single, flexible protocol for different layers of the protocol stack. In conventional stacks, protocol layers are differentiated by the distinct services each provides. RNA allows protocol stacks to adjust at runtime, which allows more dynamic composition of services, both within stacks and in the way stacks of individual hops form an overall network architecture. RNA extends the Multi-Domain Communication Model (MCDM) that emerged from the DARPA/NSF X-Bone research. RNA's approach recognizes the value of services between endpoints at a variety of scopes and layers, the similarity of service primitives at different layers, the similarity between 'real' and 'virtual' service layers, and that protocols are defined as much by the location of their endpoints as their services. During the first year, the RNA project will focus on the design of the structure of the metaprotocol and develop a subset of its services and a preliminary stack manager. RNA will explore how a single network stack can support diverse environments, and may impact the design of more flexible stacks with more useful interlayer coordination. Results will be presented at meetings and in publications, and the code will be made available on-line.
