Abstract:

With network scale and network traffic growing up,the performance of SDN controller can probably be bottleneck,in order to still obtain correct performance status on dynamical workload,an online performance monitor frame was designed and Lpdex,a controller latency performance metric,was defined. Then a simple prototype of performance monitor was implemented on FloodLight,a widely used controller,after experimental evaluation,controller performance monitor was validated feasible and Lpdex can indicate controller latency performance accurately online with workload varying.

Key words: software defined networking, performance monitor, performance metric
