OpenDaylight Project Releases Hydrogen

By Paula Bernier February 05, 2014

An important new element has come to the table for the communications industry, and it’s called Hydrogen. That’s the name of the open source software released today by the OpenDaylight Project.

This news today is important because it represents an important benchmark in the forward movement of one of the leading groups working to advance network functions virtualization and software-defined networking.

Hydrogen is now available in three versions for download so academics, enterprises, equipment providers and service providers can use it to evaluate and/or deploy NFV and SDN. Options include the Base Edition, which is for efforts leveraging SDN and OpenFlow for proof-of-concepts or academic initiatives in physical or virtual environments; Virtualization Edition, which is for data centers; and Service Provider Edition, which is for carriers on a path to network transformation based on NFV and SDN.

Key features of each option include a modular, extensible, scalable and multi-protocol SDN controller based on OSGi; an OpenFlow plugin; an OpenFlow protocol library; Open vSwitch Database configuration and management protocol support; and Java-based NETCONF and YANG tooling for OpenDaylight projects. The Virtualization Edition includes everything noted above, plus APIs to express workload relationships and service levels; a DDoS detection and mitigation framework; multi-tenant network virtualization based on overlays, including control plane and Open vSwitch-based data plane; and a multi-tenant network virtualization application using OpenFlow. The Service Provider Edition, which also includes the Base Edition, adds APIs to express workload relationships and service levels; support for traffic engineering with a BGP protocol library and topology model, and path programming model; a DDoS detection and mitigation framework; a locator/identifier separation protocol plugin, LISP mapping service that can be used to implement virtual networks; and SNMP protocol support and APIs to manage Ethernet switches.

OpenDaylight came together in an effort to simplify network management, explained David Meyer, technical steering committee chair of the group, which has plans to issue subsequent releases in the future. Members include such companies as Brocade, ConteXtream, Ericsson, IBM, Inocybe, NEC, Radware, and Qosmos. The group now has 154 people contributing and more than a million lines of code.
