Collaborative Research: Eager: An Application Delivery Platform for Mobile Apps on Global Clouds

近年来，移动的应用出现爆炸式增长，其中大部分需要服务于全球受众。云计算为应用服务提供商提供了独特的机会来管理和优化地理上分布的计算资源上的应用交付。这个项目的主要研究人员正在开发一个开放的应用程序交付网络平台，使互联网服务提供商（ISP）能够向应用程序服务提供商提供负载平衡，容错和许多其他应用程序交付服务。PI还计划增强软件定义网络的流抽象层，以使用其他几项最新创新（如跨层通信、ID/MPLS拆分、类似MPLS的标签交换）为应用级流提供足够的支持。声明将通过在原型交换机实现上设计的用例场景的概念验证实现来验证。所提出的设计的一个目标是在某种意义上是渐进的，它可以共存，并向后兼容当前的互联网，现在可以逐步部署少量的新设备。正在进行的研究旨在改变互联网上的应用程序交付。它将为开发一套通用的架构原语，可用于开发共享网络基础设施上的应用程序特定的网络作出重大贡献。

In recent years, there has been an explosive growth in mobile applications, most of which need to serve global audiences. Cloud computing provides unique opportunities for the application service providers to manage and optimize application delivery over geographically distributed computing resources. The PIs of this project are developing an open application delivery network platform which will allow Internet Service Providers (ISPs) to offer load balancing, fault tolerance, and numerous other application delivery services to the application service providers. The PIs also plan to augment the flow abstraction layer of Software Defined Networks to add adequate support for application-level flows using several other recent innovations such as cross-layer communication, ID/Locator split, MPLS-like label switching. The claims will be validated through a proof-of-concept implementation of a use-case scenario designed over a prototype switch implementation. A goal of the proposed design is to be evolutionary in the sense that it can coexist and is backward compatible with the current Internet and can be deployed incrementally now with a small number of new devices. The in-going research is designed to transform application delivery over the Internet. It would make significant contributions towards developing a set of generic architectural primitives that may be used for developing application specific networks on shared network infrastructure.
