Integrated Future Internet Architecture

这项研究旨在通过对建筑方案的交叉和综合比较分析，在NSF未来的互联网架构计划的基础上，对其进行补充和增强。在过去的6年里，国家科学基金会创建了一系列项目，重点关注新的互联网架构和将网络嵌入到更大的社会背景中：其中包括未来互联网设计(FIND)计划、网络科学与工程(NetSE)计划和未来互联网架构(FIA)征集。这一系列项目解决了一个大胆的目标--展望未来，挑战研究界设计15年后世界将需要的全球网络。在整个计划的当前阶段，一些团队已经得到资助，为未来互联网的设计制定综合建议。这些项目中的每一个都有望为未来网络体系结构的一种或另一种方法提供一个连贯的理由，但项目的总体结果应该远远不止于此：它还应该导致对设计偏好和替代方法的总体洞察，关于网络系统设计的一般性教训，以及设计网络并得出一种对需求的响应比另一种更可取的结论的更系统的理由。FIA项目应该推动原则性网络设计的前沿，这一阶段的计划已经为这一令人兴奋的步骤奠定了基础。该奖项通过一个补充现有奖项的研究计划来解决这些更大的项目目标，通过审视项目(和其他相关的架构工作)来寻求更综合和全面的结论。考虑到对互联网这样复杂的系统可能提出的目标和要求的多样性，以及设计方法的多样性，这一挑战是困难的。与许多计算机科学研究不同的是，这一议程侧重于比较分析，而不是工程设计。在适当的情况下，将通过与网络设计有关的特定主题的跨项目研究，与各个项目合作进行研究。调查员将寻求让更广泛的社区中考虑到网络体系结构高级问题的其他人参与进来，并将对网络设计的原则和方法进行自己的研究。调查员还将参加国际汽联的PI会议，因为这些会议将以跨项目的方式探讨具体主题。智力优势：这个NSF计划应该有助于实现使网络体系结构设计更加有条不紊和系统化，而不是一门艺术的长期目标；本研究将这一目标作为其最高级别的目标。本研究的目标是发现和阐明有关网络设计问题的基本见解和结论，以及通过不同方法查看各种不同项目所产生的结果。主题将包括核心网络功能，如寻址和转发，处理安全和可用性等重要要求，架构研究的新领域，如以信息为中心的网络，以及架构设计选择与更大的社会、经济和背景需求之间的关系。更广泛的影响：本研究将为未来网络设计的研究提供一个结构和方向，并提供一种新的、更有原则性的网络教学方式。今天，大多数网络课程通过教授大量事实来处理这一主题：报头的格式、协议的操作等，而较少强调？为什么？在设计上。研究人员之前的工作论文至少被用于一门网络体系结构的高级课程，本研究的目标之一是开发适合网络体系结构教学的材料。这项研究的结果也有助于将结果从国际汽联项目转移到商业世界。调查员还将继续向社区提供支持，以实现项目目标。

This research is intended to build on, complement, and enhance the NSF future Internet architecture programs through cross-cutting and integrative comparative analysis of architectural proposals. Over the last 6 years, the National Science Foundation has created a series of programs focused on new Internet architecture and the embedding of networking into the larger social context: these include the Future Internet Design (FIND) program, the Network Science and Engineering (NetSE) program, and Future Internet Architecture (FIA) solicitation. This sequence of programs address a bold objective?to look into the future and challenge the research community to design the global network that the world will need fifteen years from now. In the current stage of the overall program, a number of teams have been funded to develop integrated proposals for the design of a future Internet. Each of these projects can be expected to produce a coherent justification for one or another approach to the architecture of a future network, but the overall outcome of the project should be much more than that: it should also result in overarching insights into design preferences and alternative approaches, general lessons about network system design, and a more systematic rationale for designing networks and concluding that one response to requirements is preferable to another. The FIA project should push the frontiers of principled network design, and this phase of the programs has laid the foundation for this exciting step.This award addresses these larger project goals through a program of research that is complementary to the current awards, by looking across the projects (and other relevant architectural work) to seek more integrative and overarching conclusions. The challenge is difficult, given the diversity of goals and requirements that might be posed for a system as complex as the Internet, as well as the diversity of design approaches. In contrast to much of computer science research, this agenda is focused on comparative analysis, not engineering design. As appropriate, the research will be done in collaboration with the individual projects through cross-project studies on specific topics related to network design. The investigator will seek to involve others in the broader community who have given thought to high-level issues in network architecture, and will carry out his own research into principals and methods for network design. The investigator will also participate in the FIA PI meetings, since those meetings will explore specific topics in a cross-project way. Intellectual merit: This NSF program should contribute to the long-rang goal of making network architecture design more methodical and systematic, and less an art; this research sets that goal as its highest-level objective. This research has the goal of discovering and articulating fundamental insights and conclusions with respect to issues in network design, results that arise from looking across the various different projects with their different approaches. Topics will include core network functions such as addressing and forwarding, dealing with important requirements such as security and availability, new areas of architectural study such as information-centric networks, and the relation between architectural design choices and larger social, economic and contextual requirements. Broader impact: This research will provide a structure and direction for future research in network design, and provide a new and more principled way of teaching about networks. Most courses in networking today deal with the subject by teaching large numbers of facts: the formats of headers, operation of protocols, and so on, with less emphasis on the ?why? of design. Prior working papers of the investigator have been used in at least one advanced course on network architecture, and one ambition of this research is to develop materials suitable to the teaching of network architecture. The outcomes of this research can also help with the transfer of results from the FIA program into the commercial world. The investigator will also continue to provide support to the community toward the program goals.
