CAREER: Programmable Mobile Networking

移动的应用基础、移动的服务需求和底层网络技术的快速发展的性质对移动的计算和通信研究社区提出了重大挑战。现有的移动的网络体系结构表现出三个基本的限制，阻止我们迎接这一挑战：（i）缺乏对音频、视频和实时数据传输的服务质量支持;（ii）缺乏适应新的移动的用户和服务提供商需求的内在体系结构灵活性;以及（iii）实现和部署新的和独特的移动的网络架构的过程缺乏自动化。针对这些局限性，PI认为，迫切需要提出、调查和评估现有移动的网络架构的替代方案。所提出的研究远远超出了对又一实验性移动的网络架构的提议，例如，移动的IP++。本论文的研究目标是：（1）建立一个生成和原型化虚拟移动网络及其体系结构的方法论和创建环境;（2）建立一个生成和原型化虚拟移动的网络及其体系结构的方法论和创建环境; ㈡为一套独特的基线架构部署可编程基础服务、网络控制器和开放式可编程联网接口，其中将包括新的宽带蜂窝网络架构、下一代移动的因特网架构和移动的特设网络架构; ㈢演示在同一物理高速移动的联网试验平台上这些基线虚拟移动的网络的生成、可视化和管理;以及（iv）通过可视化、管理和细化来调查所产生的体系结构的体系结构设计空间中的权衡。能够剖析、产生、可视化和管理不同的虚拟移动的联网体系结构的产生网络的实现将代表网络架构师设计方式的重大转变，部署和管理新的和新颖的移动的网络架构。PI还响应了工业界和学术界对具有移动的网络和分布式系统技能的研究生的强烈需求，在教育方面采取新的创新举措。PI已经推出了无线和移动的网络的研究生课程，并正在教授另一个新创建的分布式电信系统课程。每门课程都涉及基本概念，通过介绍一些行业领先的研究人员的最先进的研究研讨会，并强调“动手”的长期项目。PI非常热衷于促进学术界和工业界之间的互动。这种互动提供了一个很好的学习机会，使学生，教师和行业都受益。

The rapidly evolving nature of the mobile application base, mobile service demands and underlying network technologies presents a significant challenge to the mobile computing and communications research community. Existing mobile network architectures exhibit three basic limitations that prevent us from meeting this challenge: (i) the lack of quality of service support for the transport of audio, video andreal-time data; (ii) the lack of intrinsic architectural flexibility in the adaptation to new mobile user and service provider needs; and (iii) the lack of automation of the process of realization and deployment ofnew and distinct mobile network architectures. In response to these limitations, the PI argues that there is a critical need to propose, investigate and evaluate alternative mobile network architectures tothose existing today. The proposed research goes far beyond a proposal for yet another experimental mobile network architecture, e.g., mobile IP++. Rather, it calls for new innovative approaches to the way wedesign, develop, deploy, observe and analyze next-generation mobile networking architectures in response to the future needs and requirements of mobile users, service providers and equipment vendors.The goal of this research in "spawning networks" is to: (i) establish a methodology and creation environment for spawning and prototyping virtual mobile networks and their architectures; (ii) deploy programmable foundation services, network controllers and open programmable networking interfaces for a distinct set of baseline architectures that will include a new broadband cellular network architecture, next-generation mobile Internet architecture and mobile ad hoc network architecture; (iii) demonstrate the spawning, visualization and management of these baseline virtual mobile networks over the same physical high-speed mobile networking testbed; and (iv) investigate trade-offs in the architectural design space of the spawned architecture through visualization, management and refinement.The realization of spawning networks capable of profiling, spawning, visualizing and managing distinct virtual mobile networking architectures will represent a major shift in the way network architects design, deploy and manage new and novel mobile networking architectures.The PI is also responding to the strong demands from industry and academia for graduate students with mobile networking and distributed systems skills through the introduction of new and innovative initiatives in education. The PI has introduced a graduate-level course in Wireless and Mobile Networking and is teaching another newly created course in Distributed Telecommunications Systems. Each course addressesfundamental concepts, through the presentation of state-of-the-art research seminars from some of industry's leading researchers and emphasizes "hands on" term projects. The PI is very keen to promoteinteraction between academia and industry. This interaction provides a great learning opportunity benefiting students, faculty and industry alike.
