Decoupling of the control and data planes of the network to improve efficiency. Communication from a SDN controller via a protocol to network devices both physical and virtual.

Automation

Dynamic Networks

Security

Heterogeneous Management

Abstractions allow for programmable networks.

Network can be changed quickly via a controller

Network offerings can match virtualization offerings for finer grained security in a highly volatile compute landscape.

Single control point for various devices.

Software Defined Networking Overview

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". The growing OpenFlow ecosystem now includes routers, switches, virtual switches, and access points from a range of vendors.

Open Flow

Open vSwitch is a production quality,

multilayer virtual switch licensed under the

open source Apache 2.0 license. It is

designed to enable massive network

automation through programmatic extension,

while still supporting standard management

interfaces and protocols (e.g. NetFlow,

sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag).

OpenDaylight With OpenStack• Who: Equation / EcoloTIC Green Cloud

Public/Private partnership in Quebec• What: Green Cloud to manage Smart

Campus (Locks, Water, Lighting, Heating etc)

• How: L2 Network Virtualization (OVSDB Netvirt) with OpenStack – In production w/ 100s cores, 100s TB Storage etc.

• Future: Metrics Collection (TSDR) from Sensors

#odsummit

OpenDaylight in the WAN ● Objective: Self-provisioned

dynamic network services

● What: Telstra PEN Platform - Layer 2 Ethernet virtual cross connect (VXC) forwards frames between any 2 endpoints on the network

How Comcast is Leveraging OpenDaylight

“Comcast is motivated to reduce the operational complexity of our networks. We’re working toward creating an architecture where the core of the network is not intimately involved in the operation of virtual networks.” – Chris Luke, senior principal engineer, Comcast

Early PoCs with OpenDaylight:• Network intelligence abstraction – allowing apps to query the network without

adding complexity to the forwarding plane• Overlay edge services – using IPv6 as an underlay at the network edge
