OpenDaylight Expands Open Source SDN
Page 1 of 1
OpenDaylight is run as a collaborative project operated by the Linux Foundation, which is no stranger to the world of open source collaboration. Jim Zemlin, executive director at the Linux Foundation, told Enterprise Networking Planet that while there is a lot of interest in open source SDN, the Linux Foundation is not actively recruiting members for the OpenDaylight Project.
"Just like Linux, investments in OpenDaylight will allow companies to reap the benefits of the collaborative development model and accelerate the delivery to customers of products and services on top of OpenDaylight," Zemlin said. "There certainly is a lot of interest among the companies we're in conversations with, but also, just like Linux, anyone can participate and contribute, regardless of being a member. "
In addition to the new members, the OpenDaylight project is adding some new technology to its mix. The first project undertaken by OpenDaylight was its controller initiative, now being complemented by another technology known as Virtual Tenant Networks (VTN).
David Meyer, technical steering committee chair at the OpenDaylight Project, explained to Enterprise Networking Planet that VTN technology enables Layer 2 and Layer 3 multi-tenant virtual networks.
"Not only is the functionality provided essential to network virtualization, the technology itself is quite interesting and features a unique 'logical abstraction plane' (LAP)," Meyer commented. "The LAP allows us to design and deploy any desired network topology (L2 and/or L3 functionality) without knowing the physical network topology or bandwidth restrictions."
