Software Defined Networking (SDN) offers the promise of increased agility, programmability, and revenue services opportunities. This comes with a cost, however, in the form of additional routing and traffic engineering mechanisms—with associated protocols and APIs. Many of SDN’s capabilities result from the centralization of control, engendering concerns over controller reliability, scalability and performance. Hence, it’s critical to verify the functionality and performance of all SDN components. Thorough validation of new technologies in the lab helps reduce CAPEX by preventing expensive truck rolls and reducing customer churn. Read about the configurations and tests you need to guarantee a trouble-free SDN deployment.
