Abstract

Due to increasing number of versions of OpenFlow protocol, it is getting harder day by day to use isolated data structure support of OpenFlow protocol. There is high degree of variability between each versions of OpenFlow protocol. Each version of OpenFlow specifies an interface and the collection of abstractions present in a switch that can be manipulated. So our focus of this thesis is to use the data structure (Avro) which supports OpenFlow protocol through software infrastructure proposed by Warp development group. Using this we have developed the OpenFlow version 1.2 support to Warp controller. Warp architecture uses Avro data structure which has advantages like easy integration of new version, update existing version and apply run time changes, version control, data exchange and easy schema processing which heavily impact on performance and flexibility of OpenFlow controller. These mentioned factors are compared against other OpenFlow controller architectures such as Floodlight, Ryu etc. Comparing obtained observations with different architectures conclude that Warp is more flexible architecture as compared to Floodlight and Ryu.
