  • cloud orchestration = automation + integration + best practices.The stitching together of best practices and automated tasks and processes becomes essential to optimize a wide spectrum of workloads types. In addition to rapid service delivery, the benefit of orchestration is that there can be significant cost savings associated with labor and resources by eliminating manual intervention and management of varied IT resources or services.OpenStack Quantum, FlowVisor, FloodlightAn SDN controller is an application in software-defined networking (SDN) that manages flow control to enable intelligent networking. SDN controllers are based on protocols, such as OpenFlow, that allow servers to tell switches where to send packets. The controller is the core of an SDN network.
  • European Organization for Nuclear researchHome Box Office – American premium cable and satellite television networkOne of the most talked about applications of SDN is the consolidated data-center. The first use-case example has been Infrastructure as a Service (IaaS)Other uses of SDN in enterprise or carrier managed network services (MNS) address the traditional and geo-distributed campus network. These environments were always challenged by the complexities of moves-adds-changes, mergers & acquisitions, and movement of users. Based on SDN principles, it expected that these identity and policy management challenges could be addressed using global definitions and decoupled from the physical interfaces of the network infrastructure.

    • 1. Software Defined NetworkingMichael Aro
    • 2. Software defined networking (SDN) is a formof networking in which control over how data traffic is forwarded to its destination is separated from the switching hardware.This technology is changing the way networksoperate and improves the ease and speed that converged compute, storage and networking solutions are created.
    • 3. In the SDN architecture, the control and data planes are decoupled and the network infrastructure is abstracted from the applications. OpenFlow is the protocol specification andreference implementation of Software Defined Network (SDN)
    • 4. Separation of control and data plane
    • 5. Separation of control and data plane
    • 6. Traditional Networks• Applications send data over the network (and observe network service levels), but do not interact directly with the network infrastructure.• Infrastructure uses distributed algorithms to determine forwarding and routing decisions, and uses internal configuration for security and quality of service settings.
    • 7. SDN Networks• Applications specifies network design and policies• Control compile these policies into forwarding instructions and uses the OpenFlow protocol to set the instructions on the switches and routers• Infrastructure execute these forwarding instructions and report flow statistics to the controller

    • 15. Benefits• Ability to apply a wide variety of policies at the session, user, device and application levels which help applications quickly adapt to the state of the network and user needs• Ability to manage and control networking elements from a centralized point• Programmability of the network infrastructure by the entire ecosystem (e.g., users, enterprises, independent software vendors, etc.)• Improved automation and management through the use of common application programming interfaces (APIs)
    • 16. Anticipated Benefits• In the datacenter, network virtualization can improve server utilization, help optimize bandwidth usage and provide tighter integration with storage• In the campus, SDN can help enforce policies consistently across both wired and wireless networks for a consistent and secure user experience.• Programmability of the network infrastructure by the entire ecosystem (e.g., users, enterprises, independent software vendors, etc.)• Improved automation and management through the use of common application programming interfaces (APIs) Visualizing Openflow/SDN
