![233. Virtualization of Networking (aka SDN - Software Defined
Networking)
Software-defined networking (SDN) is an approach to
computer networking that allows network administrators to
manage network services through abstraction of lower-level
functionality. This is done by decoupling the system that
makes decisions about where traffic is sent (the control
plane) from the underlying systems that forward traffic to the
selected destination (the data plane). The inventors and
vendors of these systems claim that this simplifies
networking.[1]
SDN requires some method for the control plane to
communicate with the data plane.

- 3. The course has some prerequisites: The participant should have some basic skill sets like loading an OS, booting a system from CD, Network Configuration, Thumb Drive etc., Users should be conversant with Protocols like TCP,CIFS, NFS etc., All the modules mentioned above can be learnt independently but the Virtualization of processing power should be learnt first. A basic understanding of Networks, Internet Connectivity etc is essential. 3

- 5. 5What is MAINFRAME Technology? A mainframe computer is a very large computer capable of handling and processing very large amounts of data quickly. They are used by large institutions, such as government agencies and large corporations.
- 6. 6 What is Enterprise client-server? Enterprise computing is the name given to distributed computing as practiced in medium-sized or large organizations where the need to share data between physically-distributed sites is the primary motivator for the creation of a distributed system. In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs.
- 7. 7 What is Cloud Technology? Cloud is a broad term and cannot be easily expanded in one single line. Cloud can be IaaS, PaaS, AaaS and again there are many internal small things that have to be understood to have a clear grip on the massively disruptive technology.

Virtualization of Networking (aka SDN - Software Defined Networking) Software-defined networking (SDN) is an approach to computer networking that allows network administrators to manage network services through abstraction of lower-level functionality. This is done by decoupling the system that makes decisions about where traffic is sent (the control plane) from the underlying systems that forward traffic to the selected destination (the data plane).

- 24. 24 Control Plane: A major function of the control plane is deciding which routes go into the main routing table Data Plane: In routing, the forwarding plane, sometimes called the data plane, defines the part of the router architecture that decides what to do with packets arriving on an inbound interface. SoftwareDefinedNetworking
- 26. 26The Three Key Elements of SDN: Ability to manage the forwarding of frames/packets and apply policy; Ability to perform this at scale in a dynamic fashion; Ability to be programmed. SoftwareDefinedNetworking

- 28. 284. Identity Access Management: Identity management (IdM) is the task of controlling information about users on computers. Such information includes information that authenticates the identity of a user, and information that describes information and actions they are authorized to access and/or perform. It also includes the management of descriptive information about the user and how and by whom that information can be accessed and modified. Managed entities typically include users, hardware and network resources and even applications. In computing, identity management (IdM) describes the management of individual principals, their authentication, authorization, and privileges within or across system and enterprise boundaries with the goal of increasing security and productivity while decreasing cost, downtime and repetitive tasks.

- 31. 31Imaging Service: Imaging Service is a generic term and is being used almost everyday by the Administrators even general users also. Whenever we are using a bootable CD, we are using an Imaging Service. ISO image is a classic example of Imaging Service. Every Commercial or non commercial entities are providing proprietary formats as far as Imaging Service is concerned: A multi-format image registry, the image service allows uploads of private and public images in a variety of formats, including: 1.Raw 2.Machine (kernel/ramdisk outside of image, a.k.a. AMI) 3.VHD (Hyper-V) 4.VDI (VirtualBox) 5.qcow2 (Qemu/KVM) 6.VMDK (VMWare) 7.OVF (VMWare, others) ImagingService
