What does Capwap do in a controller based wireless system?

The Control And Provisioning of Wireless Access Points (CAPWAP) protocol is a standard, interoperable networking protocol that enables a central wireless LAN Access Controller (AC) to manage a collection of Wireless Termination Points (WTPs), more commonly known as Wireless Access Points.
A.

What is a wireless access point controller?

A thin AP is simply an access point that is managed by a WLAN controller. The WLAN controller provides the thin AP its configuration and also functions as a switch for all the wireless traffic. The WLAN controller also consolidated management for the entire wireless network in one place.
  • How does the wireless technology work?

    Magnetism through the air : sending all the right signals. Transmitters and receivers sit at each end of a wireless system, using an aerial or antenna at each end. At the receiver, the electromagnetic waves create or 'induce' small electrical signals in the antenna, which are picked up by an electrical circuit.
  • What does Lwapp stand for in networking?

    Lightweight Access Point Protocol or LWAPP is the name of a protocol that can control multiple Wi-Fi wireless access points at once. This can reduce the amount of time spent on configuring, monitoring or troubleshooting a large network. The system will also allow network administrators to closely analyze the network.
  • What is IEEE best known for what wireless standard?

    One of the more notable are the IEEE 802 LAN/MAN group of standards, with the widely used computer networking standards for both wired (ethernet, aka IEEE 802.3) and wireless (IEEE 802.11 and IEEE 802.16) networks.
B.

How does WLC work?

Access points, called Lightweight Access Points (LAPs) in the unified environment, register themselves with a WLC and tunnel all the management and data packets to the WLCs, which then switch the packets between wireless clients and the wired portion of the network. All the configurations are done on the WLC.
  • What does the abbreviation WLC mean?

    WLC
    AcronymDefinition
    WLCWhole Life Costs
    WLCWhite Lined Chipboard (cardboard grade)
    WLCWorm-Like Chain
    WLCWorkload License Charges
  • What is Cisco Flex?

    Flex links is a network switch feature in Cisco equipment which enables redundancy and load balancing at the layer 2 level. The feature serves as an alternative to Spanning Tree Protocol or link aggregation.
  • When did WIFI come out to the public?

    Information is then exchanged between the transmitter and the device. WiFi was invented and first released for consumers in 1997, when a committee called 802.11 was created. This lead to the creation of IEEE802.11, which refers to a set of standards that define communication for wireless local area networks (WLANs).
C.

What is a controller in networks?

A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter or physical network interface, and by similar terms) is a computer hardware component that connects a computer to a computer network.
  • What is the controller in MVC?

    MVC Framework - Controllers. Advertisements. Asp.net MVC Controllers are responsible for controlling the flow of the application execution. When you make a request (means request a page) to MVC application, a controller is responsible for returning the response to that request.
  • What is a controller in process control?

    Closed-loop control is used to achieve this. The process controller looks at a signal representing the process value, compares it to the desired setpoint and acts on the process to minimize the difference (error). The method used by the controller to correct the error is the control mode.
  • What is the wireless controller?

    A wireless LAN (WLAN) controller is used in combination with the Lightweight Access Point Protocol (LWAPP) to manage light-weight access points in large quantities by the network administrator or network operations center. The wireless LAN controller is part of the Data Plane within the Cisco Wireless Model.
