•
Software Defined Networking (SDN)
–
New network architecture
–
Separates the network control plane from the
forwarding hardware.
–
Allows the data plane to be defined by a logically
centralized controller (or set of controllers).
•
OpenFlow
–
Standard protocol used between the control and
data planes
–
environment that allows for experimentation of
networking protocols and traffic flows without
interrupting the operation of the “production”
network.

APP
• A controller can use this API to control or
selectively modify the forwarding of
traffic flows in the network
• It is a standard defined by the Open
Networking Foundation (ONF)
APP
• OpenFlow is a protocol specification
defining an API to the switch forwarding
plane
• It enables selective centralization of flow
control with variable grain flow control

OpenFlow 1.0 and 1.3
Features
Benefits
OpenFlow 1.0- Single Table
Simple programming model, validation of SDN value proposition, early proof of concepts
OpenFlow 1.3
Multiple table
Increase performance and scalability.
Groups
Allows for multipathing or redundancy.
Tags: MPLS & VLAN
Flexibility in programing
Virtual Ports
additional flexibility in programing the forwarding plane with rules that can match against
more information contained in Ethernet packets.
Controller connection
Failure
Simpler modes to deal with the loss of connectivity with the controller
Extensible Match support
Dramatically increases flexibility.
Controller role-change
mechanism
allows the switch to be aware of a controller’s role – eg failover from primary controller to the
secondary
IPV6 Support
OpenFlow 1.3 provides IPV6 support
Per-flow meters
Measure and control the rate of packets.
