项目摘要
Named data networks (NDNs) represent a nascent vision for the future Internet that is ideal for military and industrial applications. By design, NDNs break from the conventional end-to-end, host-centric, communication and hence eliminate the thin hourglass IP waist in the current Internet stack and it accompanying security vulnerabilities. NDNs focus on movement of packets uniquely identified by their content names without their source and destination hosts' identities. Hence, frequently requested objects (e.g., web pages, streamed media and scientific data) can be cached in routers and delivered without repeated per-user transmissions. NDNs maintain a simple philosophy of limiting network traffic to content interest and corresponding data packets and are said to democratize the Internet since any entity can publish and consume data. By construction, they avoid many of the current problems including mobility, security and the high cost of content distribution.
Full realization of NDNs poses a number of obstacles. To avoid repeated scenarios of abandoning new technologies (e.g., IPv6), architectures must be gradually deployed and co-exist with the current infrastructure, but eventually installed as a clean slate solution. Furthermore, the newly emerging big-data and Internet-of-things applications along with the futuristic vision of the Internet as a searchable content directory is leading to an unprecedentedly massive size of referenced content namespaces, large routers' forwarding tables and a major scalability issue. Indeed, creating, looking up and managing exponentially increasing routing and caching tables is a major challenge. Finally, analogous to the ever pressing need for service differentiation in IP networks, content differentiation with efficient business models must be developed.
This proposal aims at designing and implementing an efficient self-management architecture for NDNs. It takes advantage of two prominent technologies; the first, virtual network (VN) slicing, is employed to achieve a scalable hierarchy of isolated but collocated and dynamically customizable NDNs. Each slice serves an intelligently and dynamically partitioned subspace of contents providers. NDNs routers' resources will be virtualized and sliced adaptively to react to changes in contents supply and demands. Partitioning and resource optimization techniques will be investigated to achieve functional scalability of these networks. Finally, through the use of the second technology, namely, network software-ization through virtual network functions, the proposed work will realize fair, application agnostic, ultra-low delay self-adaptive routing as well as content and service differentiation.
The significance of the developed architecture and algorithms will stem from their ability to self-evolve to enhance their performances or to face changes in the problem domains.
命名数据网络(NDN)代表了对未来互联网的一种新的设想,是军事和工业应用的理想选择。通过设计,NDN打破了传统的端到端,以主机为中心的通信,从而消除了当前互联网堆栈中薄的沙漏IP腰部及其伴随的安全漏洞。NDN专注于由其内容名称唯一标识的数据包的移动,而无需其源和目的主机的身份。因此,频繁请求的对象(例如,网页、流媒体和科学数据)可以被缓存在路由器中并且在没有重复的每用户传输的情况下被递送。NDN保持了一种简单的理念,即将网络流量限制在内容兴趣和相应的数据包上,并且据说使互联网民主化,因为任何实体都可以发布和消费数据。通过构建,它们避免了当前的许多问题,包括移动性、安全性和内容分发的高成本。
全面实现NDNs存在许多障碍。避免重复放弃新技术的情况(例如,IPv6),体系结构必须逐步部署并与当前基础设施共存,但最终作为一个全新的解决方案安装。此外,新出现的大数据和物联网应用沿着互联网作为可搜索内容目录的未来愿景,正导致引用的内容命名空间、大型路由器的转发表和主要的可扩展性问题的空前巨大的规模。事实上,创建、查找和管理呈指数级增长的路由和缓存表是一项重大挑战。最后,与IP网络中日益迫切的服务差异化需求类似,必须开发具有高效商业模式的内容差异化。
本建议旨在设计和实施一个有效的自我管理架构的NDNs。它利用了两个突出的技术;第一,虚拟网络(VN)切片,是用来实现一个可扩展的层次结构的隔离,但并置和动态可定制的NDN。每个切片服务于内容提供者的智能且动态划分的子空间。NDN路由器的资源将被虚拟化和自适应切片,以响应内容供应和需求的变化。分区和资源优化技术将被调查,以实现这些网络的功能可扩展性。最后,通过第二种技术,即通过虚拟网络功能实现网络软件化,实现公平、应用无关、超低时延的自适应路由以及内容和业务的差异化。
所开发的架构和算法的重要性将源于它们的自我进化能力,以提高它们的性能或面对问题域的变化。
