OpenDaylight "Hydrogen" taking shape

Slated for December release with sneak peeks beforehand; Juniper dismissal shrugged off

The OpenDaylight Project has announced new details on its SDN controller architecture, including the name of the first release scheduled for December: "Hydrogen."

OpenDaylight Hydrogen is designed to accommodate a wide range of enterprise and service provider use cases.  It includes new and legacy protocols such as Open vSwitch Database Management Protocol (OVSDB), OpenFlow 1.3.0, BGP and Path Computation Element Protocol.

It also includes multiple methods for network virtualization and two initial applications: Affinity Metadata Service to aid in policy management, and Defense4All for Distributed Denial of Service attack protection. A plugin for OpenStack Neutron has been integrated, the consortium says, and the Open vSwitch Database project will allow management from within OpenStack.

Projects were contributed by Cisco, ConteXtream, Ericsson, IBM, Industrial Technology Research Institute, NEC, Pantheon, Plexxi, Radware and developers Brent Salisbury and Evan Zeller from the University of Kentucky.

The OpenDaylight community is working to further refine the platform's service abstraction layer to produce an API that can be used over an array of network devices, says David Meyer, project chair.

OpenDaylight allows enterprise users and service providers to be "fully vested" in the SDN technology running their networks and have direct access to the people building it, the consortium says.

Users and developers got a preview of Hydrogen today at the OpenDaylight Mini-Summit in New Orleans. Another is taking place October 22 in Edinburgh, Scotland.

And as for those contributing and non-contributing vendors who, like Juniper, are less than enthusiastic about OpenDaylight and forming their own open source SDN alternatives, c'est la vie, says Jim Zemlin, executive director of the Linux Foundation:

Open sourcing technology isn't new and, in fact, is becoming the norm. Many companies choose to open source their software so that customers can get "under the hood" to test and build within lab environments. As Juniper has said, they plan to submit the OpenContrail source code to OpenDaylight and, as always, any contribution is subject to community approval.
