What is OpenDaylight SDN controller?

OpenDaylight is an open source SDN controller / framework, hosted by the Linux Foundation. It’s one of the more popular (open source) SDN controllers at the moment. One of the southbound interface protocols it supports is OpenFlow. You could buy some hardware that supports OpenFlow but a great alternative is Mininet.

How OpenDaylight is related to SDN?

The OpenDaylight Project is a collaborative open-source project hosted by the Linux Foundation. The project serves as a platform for software-defined networking (SDN) for open, centralized, computer network device monitoring.

What is the purpose of an SDN controller Cisco?

SDN controllers are the brains of the network, offering a centralized view of the overall network. Southbound APIs relay information to the switches and routers in network. Northbound APIs communicate with the applications and deploy services.

How does SDN switch work?

An SDN switch is a core for switching SDN technology, and a Cisco SDN training can teach you how this technology works. When an SDN switch acquires a data packet for which the flow is not known, it reaches out to the SDN controller, known as the server, for instructions as to what to do with the data packet.

Which southbound protocol is used by OpenDaylight?

OpenFlow
Most applications only use a small subset of the available southbound plugins to control the data plane. The NetVirt application of the Red Hat OpenDaylight solution uses OpenFlow and Open vSwitch Database Management Protocol (OVSDB).

Who uses OpenDaylight?

OpenDaylight is in production in more than 150 organizations around the world–from large telecom carriers collectively supporting 1 Billion subscribers, to webscale content providers to enterprises, research organizations and universities.

What are the main components of SDN controller?

A typical representation of SDN architecture comprises three layers: the application layer, the control layer and the infrastructure layer. These layers communicate using northbound and southbound application programming interfaces (APIs).
