SDN Controller must provides:1. Management of network state (ex: database) database serve as

repository about information from the controlled network elements. (ex: network state, topology, etc)

2. High level data model that captures the relationships between managed resource. (Yang modeling language)

3. RESTful (representational state transfer) API4. Secure TCP control session between controller with network elements.5. Provide standard protocol of application network state on network

elements.6. Must has service discovery mechanism. ex (discovery : devices,

topology), path computational system.

About1. VMware, pioneer in virtualization, the industry-leading

virtualization software company.2. Virtualizing infrastructure, from the data center to the

cloud to mobile devices.3. Deliver value to more than 500,000 customers.

vSphere : Manage Hypervisor (ESX) integrated vswitch.vCloud Director & Connector: primary app for compute, storage, image resource management, public cloud extension.vCenter Chargeback Collector : for collecting the all data.vCenter Chargeback interacts with the vCenter Server and vCenter Server database through a data collector. The data collector synchronizes the information in the vCenter Chargeback database with that in the vCenter Server database.

AboutNicira was a company focused on software-defined networking (SDN) and network virtualization. It was founded in 2007 by Martin Casado, Nick McKeown and Scott Shenker. Nicira created OpenFlow, OpenvSwitch, and the OpenStack networking project.On July 23, 2012, VMware announced they intended to acquire Nicira for $1.26 billionmore: http://en.wikipedia.org/wiki/Nicira http://www.vmware.com/products/nsx

Niciras network virtualization platform (NVP) was released in 2011,NVP now works in conjunction with the other cloud virtualization services for compute, storage, and image management.

NVP works with Open vSwitch (OVS). OVS is supported in just about every

hypervisor (OVS is shipping as part of the Linux 3.3 build.)

Nicira supports an OpenStack plug-in to broaden its capabilities in data center or resource management.

AboutMiniNet is An Instant Virtual Network on your Laptop (or other PC)Mininet creates a realistic virtual network, running real kernel, switch and application code, on a single machine (VM, cloud or native), in seconds, with a single command.more :

About

1. Runs anywhere Can bundle with install-free PyPy runtime for easy deployment2. Specifically targets Linux, Mac OS, and Windows3. Supports the same GUI and visualization tools as NOX4. Performs well compared to NOX applications written in Python (especially when run under PyPy)

Trema

About1. Trema is a OpenFlow controller framework that includes everything needed to create

OpenFlow controllers in Ruby and C.2. Open Source supported by NEC3. Trema now supports OpenFlow version 1.3.X via a repository called TremaEdge.4. Modular.

https://github.com/trema/trema-edge latest commit ? 4 days ago. 13 contributors.

1. The Trema core does not provide any state management or database storage structure.

2. The infrastructure provides a command-line interface (CLI)

3. Managing messaging and filters, and configuring virtual networks via Network Domain Specific Language (DSL, a Trema-specific configuration language).

4. There is also an OpenStack Quantum plug-in available for the sliceable switch abstraction.

AboutTRULY OPEN, OPENSTACK, WELL TESTED1. Supports various protocols for

managing network devices, such as OpenFlow, Netconf, OF-config, etc. About OpenFlow, Ryu supports fully 1.0, 1.2, 1.3, 1.4 and Nicira Extensions.

2. Open Source supported by NTT Labs

3. Python4. Has OpenStack Quantum plug-

in support5. Support a REST interface.

About1. Floodlight is a very popular SDN

controller contribution from Big Switch Networks to the open source community

2. Floodlight is based on Beacon from Stanford University.

3. Java-based OpenFlow controller.4. API interface is shared with Big

Switch Networks commercial enterprise offering Big Network Controller (BNC)

5. Developed into both SQL and NoSQL backend storage abstractions for a third-party open source storage solution

6. Floodlight offers an OpenStack Quantum plug-in

1. Controllers supporting L3VPN2. Like all SDN controllers, the

Juniper solution requires a paired agent in the network elements, regardless of whether they are real devices or virtualized versions operating in a VM

3. The communication/messaging between Control Node and vRouter Agent is intended to be an open standard using XMPP as the bearer channel.

Juniper Networks

PlexxiPlexxi Systems are based around the concept of affinity networking, offering a slightly different kind of controller a tightly coupled proprietary forwarding optimization algorithm and distribution system.The controller tasks are split between a controller and co-controllerCentral controller maintains central policy and performs administrative and the algorithmic fitting tasks, while the co-controller performs local forwarding table maintenance and fast repair.

Cisco One PK The Cisco OnePK(Platform Kit)

controller is a commercial controller.

Cisco claims the controller logic is capable of reconciling overlapping forwarding decisions from multiple applications and a service abstraction that allows troubleshooting as well as capability discovery and mapping.
