A Linear Programming Model for Latency Minimization and Fault Tolerance in Software Defined Network Controller Placement

This study proposes a mathematical model for the controller placement problem(CPP) in Software Defined Networks (SDN). For SDN networks, multiple controllers are often suitable, and location of these affects network performance. In case is at fault, resilience reliability should be ensured. Therefore, recommended optimizes number controller(s) while fault. The aims to minimize latency by considering network. simulation results show that average slightly increased whilst providing resilience. proposed can used integrate into existing networks or plan new
