Why do I need SDN technology?

SDN technology is valuable in the data center, but uses extend to other parts of the network for increased network flexibility, dynamic traffic flow, decreased latency and QoS.
Joseph Park's insight:

is it really really needed?

more best practices are needed

OpenFlow Controller for Ubuntu : Blueprints : Ubuntu

OpenFlow Controller for Ubuntu : Blueprints : Ubuntu | cloud-network | Scoop.it
Rationale:

OpenFlow enables networks to evolve, by giving a remote controller the power to modify the behavior of network devices, through a well-defined "forwarding instruction set".

OpenFlow configuration protocols: Understanding OF-Config and OVSDB

The OpenFlow protocol directs network flows, but it takes OpenFlow configuration protocols, OF-Config and OVSDB, to establish relationships between controllers and switches.
Joseph Park's insight:

ovsdb is also meaningful tool in ovs as a quantum plugin

Accepted quantum 2013.1.1-3 (source all)

quantum: Accepted 2013.1.1-3 in unstable (low) (Thomas Goirand) http://t.co/iutHmclchu #openstack
Joseph Park's insight:

Good news to test new quantum on grizzly.

The main contributors may be focusing on the new(vpc-like) functions

not on the stable basics. 

 

- waiting for stable quantum!
