EAGER: Interoperability Framework for Future Internet Architectures

信息中心网络（ICN）有望从根本上改变我们对通信的看法，从特定位置的交互转向基于名称的通信。名称可以识别从用户和设备到内容甚至虚拟实体的任何内容。 ICN被认为是构建未来互联网的关键方向，这一点可以从NSF的未来互联网架构（FIA）项目，特别是命名数据网络（NDN）和移动性第一（MobilityFirst）项目所支持的努力中得到证明。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）和名称解析（“带内”与“带外”）方面有根本差异。因此，开发一种在这些不同的网络体系结构之间进行互操作的方法将是一个重要的关注领域。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。 这是一个基本的和不断发展的问题，随着网络的发展变得更加以信息为中心，这个问题可能会越来越受到关注。虽然NDN和MobilityFirst FIA项目是以信息为中心的网络的两种具体方法，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）和结构化名称方面可能发展的基本方式的症状。从长远来看，研究不同类型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，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。 该项目使用了一种新的方法来推理互操作性，通过开发与网络架构中的特定问题相关的抽象，并查看两种仍在发展的FIA架构的具体示例。这种探索性工作的结果将是具体的抽象，然后可以将其用作架构之间互操作性的设计模式。在过去的两年里，主要研究者（PI）与NDN和MobilityFirst合作，并且处于独特的位置来开展这项工作。 PI希望找到集成仿真和测试台实验的新方法，以评估互操作性架构的可扩展性和性能。由于深入了解不同FIA架构中的权衡，这项工作将对整个NSF FIA计划产生有益的影响。预计该项目的架构贡献将是为NDN和MobilityFirst架构之间的交互工作开发机制和协议。这将为互联网向未来信息导向架构的演变带来长期利益，正如FIA计划所预期的那样。该项目还将直接支持两名研究生在加州大学滨江，美国最多样化的研究密集型大学之一，只有少数认可的研究密集型西班牙裔服务机构之一。首席研究员将开设一门关于FIA的新的研究生课程，并传播他的教育材料和研究成果。

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.
