Floware: Balanced Flow Monitoring in Software Defined Networks Academic Article uri icon


  • OpenFlow is a protocol implementing Software Defined Networking, a new networking paradigm, which segregates packet forwarding and accounting (performed on switches) from the routing decisions and advanced protocols (executed on a central controller). This segregation increases agility and flexibility of a networking infrastructure and reduces its operational expenses. OpenFlow controllers expose standard interfaces to facilitate variety of networking applications. In particular, a monitoring application can use these interfaces to push into the OpenFlow switches rules that collect traffic flow statistics at different aggregation levels. The aggregation level determines the monitoring accuracy and the induced network overhead. In this paper, we propose Floware an OpenFlow application that allows discovery and monitoring of active flows at any required aggregation level …
