The era of network programming

The Neutron project bundles different implementations of network services and solutions, such as routing, security, load balancing, and VPNs. We have explored its great extensibility by developing our own plugins and mechanism driver to fit to a certain network topology. This brings us to a new checkpoint in the network virtualization concept—programming the network flow. With the emergence of the Software Defined Network (SDN) technology, a physical network infrastructure can be programmatically operated. The SDN concept complies with the OpenStack networking service by abstracting the network resources. A major advantage of this approach is the flexibility added to the network management from user and operator perspectives. Traditional network implementations based on pure physical layouts exposes different barriers when it comes to deploying...
