With OpenFlow as a leading protocol for SDN communication between controllers and switches, many equipment vendors are looking for ways to support the protocol in their devices portfolio. A new white paper from Aricent looks at the features of its OpenFlow frameworks and explores how equipment vendors can use them to build pure or hybrid OpenFlow switches and routers.
According to Aricent, infrastructure vendors who use their OpenFlow frameworks to build equipment with pure or hybrid OpenFlow capabilities can save up to 80 percent in costs and 85 percent in time to market compared to ground-up development.
The complementary white paper highlights and diagrams Aricent’s three platform-agnostic OpenFlow frameworks, from a portable implementation of ONF OpenFlow specification version 1.3.1 to a Layer-2 and Layer-3 switching and routing framework for building hybrid OpenFlow network equipment. The white paper describes and diagrams each framework, and it explores how the different frameworks can be leveraged to build pure or hybrid OpenFlow switches for various deployments including:
- Software-only OpenFlow switch implementation on the system CPU
- A Combination of hardware- and software-based switches for pure OpenFlow
- Upgrading an existing equipment for hybrid OpenFlow capabilities
- Building hybrid OpenFlow equipment from the ground up
As SDN provides opportunities for service providers to optimize their network architecture, launch newer services, and monetize better, the paper also outlines SDN-enabled solutions including those for the WLAN, broadband access, and carrier network.
