EAGER: Interoperability Framework for Future Internet Architectures

以信息为中心的网络(ICN)承诺从根本上改变我们对通信的看法，从特定位置的交互转变为基于名称的通信。名字可以识别从用户和设备到内容甚至虚拟实体的任何东西。ICN已被认为是构建未来互联网的关键方向，NSF的未来互联网体系结构(FIA)项目目前支持的努力，特别是命名数据网络(NDN)和MobilityFirst，证明了这一点。这两种方法在命名(NDN的分层人类和机器可读名称与MobilityFirst的平面标识符)以及名称解析(带内与带外)方面存在根本差异。因此，开发一种在这些不同网络体系结构之间进行互操作的方法将是一个需要重点关注的重要领域。该项目将广泛地解决使用不同命名和名称解析方法的网络体系结构的互操作性。这是一个根本性和不断发展的问题，随着网络的发展变得更加以信息为中心，这个问题可能会引起越来越多和重大的关注。虽然NDN和MobilityFirst FIA项目是以信息为中心的联网的两种具体方法，但它们是网络在支持名称解析(这不仅是以信息为中心的环境所需的，也是MobilityFirst寻求实现的无缝移动性所需的)和组织名称方面可能演变的基本方式的症状。从长远来看，研究不同类型的命名和名称解析的体系结构的互操作性将是有价值的。这项工作的主要原因之一是，对基于名称的网络体系结构的互操作性的推理方法还处于早期阶段。这个项目使用了一种新的方法来推理互操作性，通过开发与网络体系结构中的特定问题相关的抽象，并查看两个仍在发展中的FIA体系结构的具体示例。这种探索性工作的结果将是特定的抽象，然后可以用作体系结构之间互操作性的设计模式。在过去的两年里，首席调查员(PI)与NDN和MobilityFirst都进行了合作，并处于开展这项工作的独特地位。PI希望找到集成仿真和试验台实验的新方法来评估互操作体系结构的可扩展性和性能。由于深入了解不同FIA体系结构中的权衡，这一努力将对整个NSF FIA项目产生有益的影响。预计该项目的架构贡献将是为NDN和MobilityFirst架构之间的互通开发机制和协议。这将为互联网向未来的以信息为导向的体系结构的演变产生长期好处，正如国际汽联计划所希望的那样。该项目还将直接支持加州大学河滨分校的两名研究生，该大学是美国最多元化的研究密集型大学之一，也是为数不多的经过认证的研究密集型拉美裔服务机构之一。首席调查员将提供一门关于FIA的新研究生级别课程，并传播他的教育材料以及他的研究成果。

Information Centric Networks (ICNs) promise to fundamentally change the way we think of communication, moving from location-specific interactions to name-based communication. Names identify anything from users and devices, to content and even virtual entities. ICN has been recognized as a key direction to architect the Future Internet, as evidenced by the efforts currently supported by the NSF's Future Internet Architecture (FIA) projects, especially Named Data Networking (NDN) and MobilityFirst. The two approaches have fundamental differences in naming (hierarchical human and machine readable names for NDN versus flat identifiers for MobilityFirst and in name resolution ('in-band' versus 'out-of-band'). Developing a way to interoperate between these different network architectures will therefore be an important area on which to focus.The project will broadly address the interoperability of network architectures that use differing approaches for naming and name resolution. This is a fundamental and evolving issue that is likely to be of increasing and significant concern as networks evolve to become more information centric. While the NDN and MobilityFirst FIA projects are two specific approaches for information centric networking, they are symptomatic of the fundamental ways in which networks may evolve in supporting name resolution (which is needed not just for information centric environments, but also for seamless mobility, which MobilityFirst seeks to also achieve) and structuring names. Examining interoperation of architectures of different types of naming and name resolution will be of value in the long term.One of the primary reasons for this effort is that approaches to reason about interoperability of name-based network architectures are at an early stage. This project uses a somewhat new approach to reasoning about interoperability by developing both abstractions related to specific issues in network architectures and also looking at specific examples of the two still evolving FIA architectures. The outcome of this exploratory effort will be specific abstractions that can then be used as a design pattern for interoperability between architectures. Over the last two years, the principal investigator (PI) has worked with both NDN and MobilityFirst, and is in a unique position to undertake this effort. The PI expects to find novel ways of integrating simulation and testbed experiments to evaluate scalability and performance of the interoperability architecture.The effort will have a beneficial impact on the entire NSF FIA program as a result of the in-depth understanding of the tradeoffs being made in the different FIA Architectures. It is expected that the architectural contribution from this project will be the development of mechanisms and protocols for inter-working between the NDN and MobilityFirst architectures. This will yield long-term benefits for the evolution of the Internet to a future information-oriented architecture, as intended by the FIA program. The project will also directly support two graduate students at UC Riverside, one of America's most diverse research-intensive universities and one of only a handful of accredited research-intensive Hispanic Serving Institutions. The principal investigator will offer a new graduate level course on FIA, and disseminate his educational materials as well as his research results.
