Software-defined networking (SDN) continues to revolutionize service delivery by increasing network reliability and security while decreasing the complexity of networking hardware and network management. For many SDN systems, OpenFlow – the original standard interface communications protocol – makes it all possible by enabling rapid innovation and experimentation through software control.
Testing is critical to getting the most out of an SDN network and providing end users with the best application experience. A free booklet from Ixia describes detailed methodologies to verify SDN & OpenFlow functionality and performance to help ensure networks perform at the highest level
Ixia Black Book: Why Testing Matters in SDN and For OpenFlow
The “SDN/OpenFlow Black Book” offers several stand-alone sections that outline test methodologies to verify network device and system functionality and performance. Each section provides an overview of the test case; illustrates test configurations; details configuration procedures; summarizes key test parameters; explains metrics and provides examples of expected results; and highlights how to troubleshoot common issues. The Ixia booklet covers test methodologies including:
- OpenFlow switch setup and functional test
- OpenFlow switch forwarding test
- Switch flow failover performance test
- OpenFlow controller scalability test
- Packet-out rate calculation
- Bandwidth rate limiting and QoS validation
The Ixia Black Book about SDN/OpenFlow is part of a series of Ixia Black Books that serve as primers on current technologies and key testing strategies. The series covers more than 20 IP and wireless test methodologies to help customers deploy applications and network services in a physical, virtual, or hybrid network configuration.
Other Ixia Black Books cover areas such as 802.11ac Wi-Fi benchmarking, carrier Ethernet, converged data center, and network security. While every Black Book provides step-by-step instructions using Ixia’s test platform and applications to demonstrate each test methodology, the methodologies are universally applicable to any test equipment.
