Nets-FIND: Collaborative Research: Postmodern Internetwork Architecture

事实证明，网络层创新出人意料地困难，原因有很多：现有协议忽视了相互竞争的经济利益；此外，少数协议占据主导地位，导致层违规，从而导致技术进一步根深蒂固。今天的网际网络层的许多缺点是由于它在利益相关者即用户和服务提供商的政策方面缺乏灵活性。这些失败的后果是众所周知的：各种黑客攻击、分层违规和超载被引入来执行策略，并试图在各种“角力”中占据上风。其结果是，网络变得越来越脆弱，对创新怀有敌意，容易受到攻击，对责任和隐私的担忧也不敏感。后现代网际体系结构项目的目标是设计、实施并通过日常使用评估最低限度的网际网络层和附带的辅助功能，以预测争斗并允许它们在策略空间中展开，而不是在分组转发路径中。该项目的总体目标是在不牺牲统一互联网提供的规模经济的情况下，使更大一部分网络设计空间可访问。

Network-layer innovation has proven surprisingly difficult, for various reasons: existing protocols ignore competing economic interests; also, a few protocols dominate, enabling layer violations that lead to further entrenchment of technologies. Many shortcomings of today's internetwork layer result from its inflexibility with respect to the policies of the stakeholders, namely users and service providers. The consequences of these failings are well-known: various hacks, layering violations, and overloadings are introduced to enforce policies and attempt to get the upper hand in various "tussles". The result is a network that is increasingly brittle, hostile to innovation, vulnerable to attack, and insensitive to concerns about accountability and privacy. The goal of the Postmodern Internetwork Architecture project is to design, implement, and, through daily use, evaluate a minimalist internetwork layer and accompanying auxiliary functionality that anticipates tussles and allows them to be played out in policy space, as opposed to in the packet-forwarding path. The overarching goal of the project is to make a larger portion of the network design space accessible without sacrificing the economy of scale offered by the unified Internet.
