NeTS: Large: Collaborative Research: Design Principles for a Future-Proof Internet Control Plane

当今互联网面临的最大挑战之一是日益增长的复杂性，这与日益多样化的使用模式和用户对服务质量的期望不断增长有关。 互联网中使用的核心技术IPv4和BGP是基于20世纪70年代和80年代初开发的技术，当时互联网的重点是提供简单的边缘网络和应用程序之间的连接。 相比之下，今天的用户和服务提供商想要高质量的体验，例如，流畅的高清视频、响应迅速的电子商务商店、交互式社交网络等。解决这些挑战是困难的，因为IP和BGP都被证明是非常严格的，难以修改。 虽然已经有很多关于互联网数据平面的白板提案的研究，但控制平面的研究主要集中在特定的协议上。这个项目填补了这一空白，通过使用一个整体的方法来设计互联网控制平面，可以适应有效地满足日益增长的需求放在互联网上。根据我们的经验与XIA未来互联网架构项目，我们定义了三个独立的，但相关的要求。首先，控制协议必须是可进化的，这样它们才能适应未来出现的需求。 第二，互联网路由协议必须是资源感知的。最后，互联网控制平面必须支持与日益复杂的边缘网络（如内容交付网络（CDN）和云基础设施）的控制平面的协调。 该项目有一个广泛的研究议程，其中包括研究在互联网中的可进化性和资源感知的协议支持，跨边缘和过境域的协调接口和技术的定义，以及控制平面架构，提供对常见的控制协议功能，如发现和控制通信的支持。 这项研究使用了几个现实世界的驱动程序，包括流量工程，云计算和大规模分布式拒绝服务（DDoS）防御服务。 最后，该项目将包括一个端到端的实验评估工作，使用大规模的测试平台，如CloudLab，GENI，和PENDIX.智力优点：该项目的主要智力优点是，它解决了三个基本的挑战，在互联网控制协议（可进化性，资源感知，和接口的协调跨异构控制平面）在一个集成的方式。这三个领域的成果将被集成到一个新的互联网控制平面架构中。更广泛的影响：该项目也将产生重大的更广泛的影响。 首先，将向研究界提供在Cloudlab、GENI和PENDIX等测试平台上运行大规模网络实验的工具。其次，该项目将吸引本科生和MS学生参与该项目，并将结果整合到CMU和UW-Madison的课程中，并将组织一个DIMACS研讨会，让社区参与讨论未来互联网控制平面设计的重要主题。 最后，重新思考网络控制平面的整体方法可以对网络研究社区和行业产生巨大影响。

One of the big challenges faced in the Internet today is the ever growing complexity associated with the increasingly diverse usage models and growing user expectations about quality of service. The core technology used in the Internet, IPv4 and BGP, is based on technology developed in the 1970's and early 1980's, when the focus of the Internet was providing connectivity between unsophisticated edge networks and applications. In contrast, today's users and service providers want high Quality of Experience, e.g., smooth HD video, responsive e-commerce stores, interactive social networks, etc. Addressing these challenges is hard because both IP and BGP have proven to be very rigid and hard to modify. While there has been much research on clean slate proposals for the Internet data plane, research in the control plane has mostly focused on specific protocols. This project fills this void by using a holistic approach to the design of the Internet control plane that can adapt to efficiently meet the growing demands placed on the Internet.Based on our experience with the XIA future Internet architecture project, we define three separate but related requirements. First, control protocols must be evolvable so they can adapt to future emerging requirements. Second Internet routing protocols must be resource aware. Finally, the Internet control plane must support coordination with the control planes of increasingly sophisticated edge networks such as content delivery networks (CDNs) and cloud infrastructure. The project has a broad research agenda that includes research in protocol support for evolvability and resource-awareness in the Internet, the definition of interfaces and techniques for coordination across edge and transit domains, and a control plane architecture that provides support for common control protocol functions such as discovery and control communication. This research uses several real-world drivers including traffic engineering, cloud computing and a large-scale distributed denial of service (DDoS) defense service. Finally, the project will includes an end-to-end experimental evaluation effort using large-scale testbeds such CloudLab, GENI, and PEERING.Intellectual merit: The main intellectual merit of the project is that it addresses three fundamental challenges in for Internet control protocols (evolvability, resource-awareness, and interfaces for coordination across heterogeneous control planes) in an integrated fashion. The results in these three areas will be integrated in a novel control plane architecture for the Internet.Broader Impact: The project will also have significant broader impact. First, tools to run large scale networking experiments across testbeds such as Cloudlab, GENI and PEERING will be made available to the research community. Second, the project will engage undergrad and MS students in the project and integrate results in courses at CMU and UW-Madison, and will organize a DIMACS workshop to engage the community in discussion on the important topic of control plane design for the future Internet. Finally, the holistic approach to rethinking the network control plane can have tremendous impact on the networking research community and industry.
