Software-Defined Networking (SDN) offers the promise of increased agility, programmability, and revenue services opportunities. While SDN has been widely deployed in data center and enterprise environments, and many service provider deployments are underway, I think the best is yet to come. According to IHS research, significant SDN deployments are expected to grow over $18 billion addressable market by the end of 2019
Many of SDN capabilities result from the centralization of control causing concerns over reliability, scalability and performance. So it is critical to test, measure, and verify the functionality and performance of all SDN components in 3 key areas listed below:
- Programmatic network control through the use of SDN controllers – In case of SDN controllers, you would want to find out test the interoperability in multi-vendor environments starting from proprietary equipment to open source controllers like ODL, ONOS and to white box switches.
- SDN infrastructure including physical and virtual forwarding nodes – When validating SDN infrastructure and overlay networks, a key measure is how dynamically you can move workloads based on resource availability and if the overlay networks be scaled as needed without compromising performance and reliability.
- Centralized management and end-to-end visibility of the network – A key aspect of successful deployment involves the selection and management of SDN components, as well as testing and deploying the end-to-end management capability for the network service in question.
Above mentioned areas are critical to success of SDN deployments and we, at Spirent, have been helping our customers to move SDN forward with confidence. For detailed test cases on how to validate your SDN environment, download this report.
