History

On December 5, 2014, the Open Networking Lab (ON.Lab) along with other industry partners including AT&T and NTT Communications released the ONOS source code to start the open source community. On October 14, 2015, the Linux Foundation announced that ONOS had joined the organization as one of its collaborative projects. The project was started around October 2012 under the leadership of Panka
Berde
an architect at ON.Lab. The name ONOS was coined around end of 2012 by Berde. Early prototype was shown in April 2013 at Open Networking Summit (ONS) and journey of initial iterations featured at ONS 2014.

container. The system is designed to operate as a cluster of nodes that are identical in terms of their software stack and can withstand failure of individual nodes without causing disruptions in its ability to control the network operation. ONOS-Tiers

While ONOS leans heavily on standard protocols and models, e.g. OpenFlow, NETCONF, OpenConfig, its system architecture is not directly tied to them. Instead, ONOS provides its own set of high-level abstractions and models, which it exposes to the application programmers. These models can be extended by the applications at run-time. To prevent the system from becoming tied to a specific configuration or control protocol, any software in direct contact with protocol-specific libraries and engaging in direct interactions with network environment is deliberately isolated into its own tier referred to as a ''provider'' or a ''driver''. Likewise, any software in direct contact with intra-cluster communication protocols is deliberately isolated into its own tier referred to as a ''store''. The platform provides applications with a number of high-level abstractions, through which the applications can learn about the state of the network and through which they can control the flow of traffic through the network. The ''network graph'' abstraction provides information about the structure and topology of the network. The ''flow objective'' is a device-centric abstraction that allows applications to direct flow of traffic through a specific device without the need to be aware of the device table pipeline. Similarly, the ''intent'' is a network-centric abstraction that gives application programmers the ability to control network by specifying what they wish to accomplish rather than specifying how they want to accomplish it. This simplifies application development and at the same time provides the platform with added degrees of freedom to resolve what would normally be considered conflicting requests. Applications (core extensions) can be loaded and unloaded dynamically, via REST API or GUI, and without the need to restart the cluster or its individual nodes. ONOS application management subsystem assumes the responsibility for distributing the application artifacts throughout the cluster to assure that all nodes are running the same application software. ONOS base distribution contains over 175 applications, which fall into numerous categories, e.g. traffic steering apps, device drivers, ready-to-use YANG models, utilities, monitoring apps. The system provides REST API, CLI and an extensible, dynamic web-based GUI. gRPC interfaces for ONOS are under active development.

Use cases

The ONOS software has been used as a platform that applications have been written on top of or has been integrated into other projects. A number o
use cases
demonstrate how the software is being used today—including global research networking deployments, multilayer network control, and central office re-designed as a datacenter.
