Abstraction to help applications write logic to handle ARP + NDP packets.

The idea is to allow applications to contribute NeighbourMessageHandlers to
handle ARP/NDP packets coming from a particular ConnectPoint, Interface or with
a particular traffic selector. Applications can contribute different handlers
for different ports, because they know how those ports will be used. Also,
multiple applications can contribute handlers for different ports/interfaces
without having to have one ARP handler for the entire network. The framework
provides actions that the handler can choose to take - flood, proxy, reply, drop.
The handler is free to implement some other action if none of these fit what it
needs to do. The framework also handles many of the common tasks for ARP handlers,
like parsing packets, abstracting the differences between ARP and NDP, implementing
actions like replying to a request. This allows handlers to be very simple and
easy to understand and implement.

ONOS : Open Network Operating System

What is ONOS?

ONOS is a new SDN network operating system designed for high availability, performance, scale-out.

Top-Level Features

  • High availability through clustering and distributed state management.
  • Scalability through clustering and sharding of network device control.
  • Performance that is good for a first release, and which has an architecture that will continue to support improvements.
  • Northbound abstractions for a global network view, network graph, and application intents.
  • Pluggable southbound for support of OpenFlow and new or legacy protocols.
  • Graphical user interface to view multi-layer topologies and inspect elements of the topology.
  • REST API for access to Northbound abstractions as well as CLI commands.
  • CLI for debugging.
  • Support for both proactive and reactive flow setup.
  • SDN-IP application to support interworking with traditional IP networks controlled by distributed routing protocols such as BGP.
  • IP-Optical use case demonstration.
