Control and Management for Next Generation Networks

当今互联网的结构造成了若干限制：它无法发挥无线通信等新兴技术的潜力;它不能提供任何可用性和可靠性保证;它本质上是不安全的;在当前互联网中，查明问题的根源极为困难;对等互联的经济激励措施不易管理和创造;为了满足不断增长的需求，它需要越来越多的电力，并且随着时间的推移成本变得越来越高。最近，人们对互联网的白板设计产生了极大的兴趣，以解决这些问题。一个很有前途的想法是使用软件定义网络（SDN），这引起了学术界和工业界的广泛关注。

The structure of today's Internet imposes several limitations: it cannot deliver the potential of emerging technologies such as wireless communications; it does not provide any guarantees on availability and reliability; it is intrinsically unsecure; identifying the root causes of problems is extremely difficult in the current Internet; economic incentives for peering are not easy to manage, and create; and in order to keep up with the growing demands, it needs more and more power, and becomes more costly over time. Recently, there has been a tremendous amount of interest in a clean slate design for the Internet to address these problems. One promising idea is to use Software-Defined Networks (SDNs) that has attracted a lot of attention both from academia and industry.
