SDN网络可扩展性问题的研究
Research on Scalability of SDN
摘要
Abstract
Software Defined Network ( SDN) provides a more flexible and a better management network,by a united control plane which decoupled from data plane to manage network event and a global network view to synchronize network status. However,as the separation between data plane and control plane increased to OpenFlow event handling additional computing and network resources consumption, with the increase of network traffic,it will inevitably make the traffic increasing between controller and switches,as well as between con-troller and the controller,and that may lead to scalability issues occurred in SDN network. In order to solve the problem of SDN network scalability,the analysis is conducted from the cause of network congestion and network device performance. Starting from reducing net-work load and designing more reasonable network device,the contribution and research in this field is analyzed and summarized in past two years.关键词
