Design and Development of New Mechanisms and Algorithms for Service-Centric Networks

在过去的二十年里，我们见证了互联网的惊人发展。这种增长越来越多地受到P2P计算、物联网(IoT)、IPTV、在线游戏、社交网络和网络搜索等新应用的引入的推动。虽然这些新应用程序通常需要在不同地点复制和分发内容，但随着智能手机和平板电脑的广泛采用，用户也变得更加移动和多宿主。当前的互联网核心不能有效地支持这些对移动性和多样性的需求，因为当前的互联网核心是以主机为中心的环境，在固定附件之间提供点对点连接。 最近在云计算方面的成功激发了人们对虚拟化技术的热情。可以通过共享的基于商品的硬件基础设施动态实例化虚拟设备，从而降低成本和提供定制服务。虽然虚拟化技术有很多好处，但如何支持虚拟环境下的移动性和多样性是需要解决的首要问题。我们的短期目标是设计和开发一些关键的新机制和算法，使虚拟化技术能够支持移动性和多样性。具体地说，我们建议创建一个新颖的域相关命名空间，并使用相关的协议和机制来支持多样性和移动性，并开发创新的算法，以促进动态资源共享，在适应多样性和移动性的同时提高系统性能。 这项拟议的计划是我们长期努力的一部分，目的是设计和开发新的机制和算法，将互联网转变为以服务为中心的网络，以降低成本和提供大量新服务来丰富人们的日常生活。它将为高素质人员提供独特和广泛的培训机会，并帮助加拿大保持在信息技术领域的领先地位。

We have witnessed the phenomenal growth of the Internet in the past two decades. This growth is increasingly driven by the introductions of new applications such as P2P computing, the Internet of Things (IoT), IPTV, online gaming, social networking, and web searching. While these new applications typically require contents being replicated and distributed over different locations, users are also becoming more mobile and multi-homed with widespread adoption of smart phones and tablets. These demands for mobility and multiplicity cannot be efficiently supported with the current core of the Internet, which is a host-centric environment that provides point-to-point connectivity between fixed attachments. Recent success on cloud computing has inspired the enthusiasm for virtualization technology. Virtualized appliances can be instantiated dynamically over shared commodity-based hardware infrastructure, leading to lower cost and customized services. While there are many benefits with virtualization technology, how to support mobility and multiplicity under virtualized environment is the top issue that needs to be addressed. Our short-term goal is to design and develop some key new mechanisms and algorithms that can enable virtualization technology to support mobility and multiplicity. In specifics, we propose to create a novel domain-dependent namespace with associated protocols and mechanisms for supporting multiplicity and mobility and develop innovative algorithms that can facilitate dynamic resource sharing and improve system performance while accommodating multiplicity and mobility. This proposed program is part of our long-term efforts to design and develop new mechanisms and algorithms for transforming the Internet into a service-centric network that can enrich people's daily lives at large with reduced costs and numerous new services. It will provide unique and extensive training opportunities for highly qualified personnel and help Canada maintain leadership in information technology.
