命名数据网的移动性支持方案

Named Data Network Mobility Support Solution

社交网络、移动应用程序和媒体流发展导致了互联网运行方式的转变。随着互联网使用的扩大,全球的网络流量和互联网用户的数量呈指数增长,造成互联网所使用的IP地址很快会被耗尽。因此,如何应对这种困境受到人们的广泛关注。在相关的解决方案中,命名数据网络(NamedDataNetwork)以其只关心内容而不关心位置的特性脱颖而出,旨在实现高效的内容分发。其中,移动性支持是重要的研究内容之一。为解决NDN的移动性支持问题,近几年提出了许多消费者和生产者的移动支持方案,笔者首先分析了NDN中移动生产者和消费者提出的问题,进而根据其特点对现有方案进行分类和说明,最后讨论了这些方案的优缺点。

The development of social networks, mobile applications and media streams has led to a change in the way the I nternet operates. With the expansion of Internet use, the global network traffic and the number of Internet users are exponentially increasing, resulting in the use of IP addresses in the Internet will soon be exhausted. Therefore, how to deal with this dilemma has attracted wide attention. Among the related solutions, Named Data Network (Named Data Network) stands out because it only cares about content but not about location, aiming at achieving efficient content distribution. Among them, mobility support is one of the important research contents. In order to solve the problem of mobile support for NDN, many mobile support schemes for consumers and producers have been proposed in recent years. The author first analyses the problems raised by mobile producers and consumers in NDN, then classifies and explains the existing schemes according to their characteristics, and finally discusses the advantages and disadvantages of these schemes.
