Network Virtualization - Coggle Diagram

- - - - The cloud provider is responsible for access to applications and services
    - - The cloud provider is responsible for providing users access to the development tools and services used to deliver the applications.
    - - The cloud provider is responsible for giving IT managers access to the network equipment, virtualized network services, and supporting network infrastructure.
  - - - Cloud-based applications and services offered in a public cloud are made available to the general population.
    - - are intended for a specific organization or entity, such as the government
    - - is made up of two or more clouds where each part remains a separate object, but both are connected using a single architecture.
    - - is created for exclusive use by a specific community.
  - - - Typically, a data storage and processing facility run by an in-house IT department or leased offsite.
    - - Typically, an off-premise service that offers on-demand access to a shared pool of configurable computing resources.
- - - - This is typically regarded as the brains of a device. It is used to make forwarding decisions.
    - - this plane is typically the switch fabric connecting the various network ports on a device.
    - - CEF is an advanced, Layer 3 IP switching technology that enables forwarding of packets to occur at the data plane without consulting the control plane.
    - - SDN is basically the separation of the control plane and data plane. The control plane function is removed from each device and is performed by a centralized controller
  - - - Open Stack
        
        is a virtualization and orchestration platform designed to build scalable cloud environments and provide an IaaS solution.
      - Other Components
        
        include Interface to the Routing System (I2RS), Transparent Interconnection of Lots of Links (TRILL), Cisco FabricPath (FP), and IEEE 802.1aq Shortest Path Bridging (SPB).
      - OpenFlow
        
        manage traffic between routers, switches, wireless access points, and a controller.
- - - - A flow table may direct a flow to a Group Table, which may trigger a variety of actions that affect one or more flows
    - - This table triggers a variety of performance-related actions on a flow including the ability to rate-limit the traffic.
    - - This table matches incoming packets to a particular flow and specifies the functions that are to be performed on the packets.
  - - - An ANP is a collection of end-point groups (EPG), their connections, and the policies that define those connections.
    - - The APIC is considered to be the brains of the ACI architecture. APIC is a centralized software controller that manages and operates a scalable ACI clustered fabric.
    - - These switches provide an application-aware switching fabric and work with an APIC to manage the virtual and physical network infrastructure.
  - - - In this type of SDN, the devices are programmable by applications running on the device itself or on a server in the network
    - - This type of SDN uses a centralized controller that has knowledge of all devices in the network
    - - This type of SDN is similar to controller-based SDN where a centralized controller has a view of all devices in the network
