About Avocet Release
Avocet is the first open source release for ONOS. It is an important milestone in the journey to bringing SDN to service provider and other mission critical networks. Developers and architects at ON.Lab and partner companies spent countless hours solving complex distributed systems problems and designing and developing the architecture of this first version. The first release of ONOS has a clean-slate, modular architecture with a distributed core for high availability, performance and scale-out. It provides Application Intent Framework- a high-level, network agnostic programmatic abstraction and interface.
Having said that, a good set of release notes should not only contain what got done, but also a candid assessment of where things fell short along with the plan to get these remaining tasks done. What got done in the Avocet release of ONOS was inline with the following priorities:
Release ONOS with coherent and modular architecture
Enable and demonstrate high-availability operation
Enable sustained pursuit of performance and scale objectives
Enable development of apps and engagement of SDN community
Demonstrate SDN-IP & Packet-Optical use cases
- User Interface
We fell short in delivering the performance at scale we had hoped to provide and a comprehensive set of associated measurements. But based on the current distributed architecture and what has been demonstrated with prior prototypes of ONOS and the preliminary measurements with Avocet release, these performance targets seem well within reach and that will be the focus of the next release Blackbird ( Feb 2015) and in fact beyond that as a sustained effort to always improve and push the limits of performance and scale.
Avocet will always remain a special release. It is the release that will get open sourced and will bring in each one of you into the ONOS community to make ONOS richer, more robust, faster and a driving force for SDN adoption!
What's in Avocet Release?
high-availability, scalability*, performance*
northbound abstractions (Application Intent Framework)
southbound abstractions (OpenFlow adapters)
ONOS code-base on GitHub
documentation & infrastructure processes to engage the community
reactive forwarding, mobility, proxy arp
*More work on this in Blackbird release
What did not get done for Avocet Release and is next for ONOS in February'15 - Blackbird release?
Prove out performance at scale
current release falls short in our own view
testing with real hardware
provide comprehensive assessment
Continue to increase robustness
defects, edge-cases, additional failure scenarios
continuous testing framework
Segment Routing use-case
Is on an older version of ONOS and will be ported to the released version of ONOS
REST API & Security
Support for OpenFlow 1.3 multiple-tables ( addressed with bringing in segment routing into mainstream ONOS)
ONOS is distributed under the Apache 2.0 license.
