Beryllium features tighter OpenStack links, more use cases

The OpenDaylight Project this week unveiled its fourth open source SDN platform release, which features enhancements in automation, resource optimization, and visibility and control.

OpenDaylight Beryllium improves on the performance, scalability and functionality of the three previous releases – Hydrogen, Helium and Lithium, OpenDaylight officials say. But Beryllium will also includes clustering and high availability, improved data handling, AMQP messaging for transport, abstraction and management extensions, and a new GUI.

Beryllium features improved analysis and testing of clustering, where multiple instances of ODL act as one logical controller. Applications that want to be cluster-aware can choose how to put data across the cluster, OpenDaylight officials say.

Also, Beryllium includes components necessary to support OpenStack High Availability and Clustering with enhanced support for OpenStack Neutron APIs and features. The new controller also features improved VTEP security and security group configuration via OpenFlow, and support for OpenStack BGP-VPNs.

Beryllium also enables workload placement on hosts with Data Plane Development Kit-accelerated virtual switches.

For intent-based policy, Beryllium supports NetIDE intent-based network modeling, as well as NEMO, Application Layer Traffic Optimization, Group Based Policy and Network Intent Composition. NetIDE enables apps written for other SDN controllers – such as Ryu, Floodlight, and Pyretic -- to work with OpenDaylight.

All of these new features in Beryllium apply to use cases in brownfield environments needing automated service delivery, network resource optimization to handle traffic growth, and visibility and control of network topology, configuration and performance, OpenDaylight officials say.

For greenfield environments, Beryllium could lend itself to regional/metro network automation for Internet of Things, smart grid and smart city applications. And for cloud/NFV deployments, Beryllium aids in opening up the OpenStack Neutron API for cloud operators to employ NFV service function chaining, OpenDaylight officials say.
