Software-Defined Networking: A Taxonomy
Gartner Report
“Ending the Confusion About Software- Defined Networking: A Taxonomy”
Defines the two main SDN approaches
“Device-Based SDN Deployment”
Control protocol such as OpenFlow provisions hardware devices
“Overlay-Based SDN Deployment”
Use IP tunnels, e.g., VxLAN, NVGRE, or STT, between vSwitches to create logical overlay networks

Physical Infrastructure Today
With an SDN enabled infrastructure
Applications: BGP, OSPF, ISIS, etc.
Applications run as distributed embedded software
the ip network as we know today is over 20 years old, back then the major goal is to provide connectivity. as the network requirement changes, 10 years later, our networking industries comes up with a new protocol suitde called mpls which is designed to provide vas service VPN and traffic engineering/fast convergence. No matter whether it is IP or MPLS, these protocols are all operated in distributed manner with both control plane and forwarding plane are tightly coupled. Because of this, exisiting ip/mpls network are operated, managed and view individually. [click]. We believe that SDN is the next most disruptive technology after MPLS. By using standard control protocol to program the forwarding plane on the exisitng network layer, we can take out some or all of the control plane previously resided on the network devices to a centralized application server and permit operator to virtualize the network infrastructure pretty much the same way hypervisor virtualize the compute resource on server infrastructure to drive down the cape and opex and be able to view and manage the network like a system instead of discrete networking device.
The network controller has two roles. It provides a single point of attachment for applications that want to use the networking functionality embedded in the network OS. The controller also coordinates the delivery of the appropriate network functionality to those applications. In order to carry out this task, the network controller understands how and where networking functions are physically distributed across the platform, how to configure ("program") them and how to connect data flows across them so that applications are supported by the right function(s) on demand. The network controller replaces manual provisioning of network hardware, enabling network functionality to be turned up faster at minimal cost.

4. Software Defined Networking: Overlay Networking
2012 APAC Leadership Summit
3/2/2012
Software Defined Networking: Overlay Networking
Approach: Build Overlay Logical Networks
East-west tunnels between software switches (vSwitch) enable physical network abstraction (logical networks)
Proposed tunnel technologies
VxLAN, STT: VMware
NVGRE: Microsoft
Technology benefits
Supports millions of logical networks (no 4K limit as VLANs)
Support VMs with overlapping IP/MAC addresses

7. OpenFlow Introduction
What is OpenFlow
Standard Protocol from ONF
OpenFlow Controller runs on a server
OpenFlow-enabled device supports an OpenFlow Client (control plane software)
OpenFlow Controller communicates with OpenFlow Client using the OpenFlow Switch protocol
OpenFlow-enabled devices have a Flow Table, fed by the OpenFlow Controller

9. OpenFlow-Enabled Device Operation
How it works?
Flow Entry
The Flow Table contains Flow Entries
Each Flow Entry represents a Flow, e.g., packets with a given destination IP address
Incoming packets are matched against the Flow Entries in priority order
Matching stops when a match occurs, and the actions for that Flow Entry are performed
Unmatched packets are typically dropped
