CNS-NeTS:Medium: A Recursive Internet Architecture

当前的互联网架构是围绕不同功能的层构建的，其中网络层在大量自治的异构网络之上提供技术独立的抽象。互联网协议（IP）是实现这种抽象的一种机制。由于选择了基本的“尽力而为”服务，Internet无法有效地响应新的需求（安全性、可扩展性、无线、移动性等）。当前IP模型的刚性结构导致了许多效率低下或不完整的ad hoc解决方案。本项目旨在开发一种全新的递归Internet架构（RINA），该架构基于网络是进程间通信（IPC）的基本原则。在这个模型中，应用程序进程（AP）通过分布式IPC设施进行通信。组成该设施的IPC进程提供了一个实现IPC机制的协议，以及一个用于管理分布式IPC（路由、安全和其他管理任务）的协议。RINA将每个IPC设施视为一个“私有”网络，因此它提供了内在的安全特性。它是递归的，因为IPC进程本身可以是从较低的IPC设施请求服务的AP。该项目将设计和开发RINA的重复结构，沿着各种有助于支持安全性、多宿主、移动性和可扩展性的政策。所开发的IPC机制建立在IPC进程的递归命名和寻址、机制和策略分离以及隔离数据传输、控制和管理的基础上。开发的原型将在小型和大型试验台上进行测试。

The current Internet architecture is built around layers of different functions, where the Network Layer provides a technology-independent abstraction on top of a large set of autonomous, heterogeneous networks. The Internet Protocol (IP) is one mechanism for achieving such an abstraction. By making the choice for a rudimentary "best-effort" service, the Internet has not been able to effectively respond to new requirements (security, manageability, wireless, mobility, and so forth.) The rigid structure of the current IP model has led to numerous ad hoc solutions that are either inefficient or incomplete.This project is aimed at developing a clean-slate Recursive Internet Architecture(RINA) that is based on the fundamental principle that networking is inter-process communication (IPC). In this model, application processes(APes) communicate via a distributed IPC facility. The IPC processes that make up this facility provide a protocol that implements an IPC mechanism, and a protocol for managing distributed IPC (routing, security and other management tasks). RINA views each IPC facility as a "private" network, thus it offers intrinsic security features. And it is recursive in that the IPC processes can themselves be APes requesting services from lower IPC facilities. This project will design and develop the repeating structures of RINA, along with various policies seen useful in support of security, multihoming, mobility, and manageability. The developed IPC mechanisms build upon recursive naming and addressing of IPC processes, separation of mechanism and policy, and isolating data transfer, control and management. The developed prototype will be tested on small and larger-scale testbeds.
