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.
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.
  • 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.
  • What is a proportional control system?

    In the proportional control algorithm, the controller output is proportional to the error signal, which is the difference between the setpoint and the process variable. In other words, the output of a proportional controller is the multiplication product of the error signal and the proportional gain.
  • 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 is Capwap tunneling?

    A. When the AP joins a WLC, a Control and Provisioning of Wireless Access Points protocol (CAPWAP) tunnel is formed between the two devices. All traffic, which includes all client traffic, is sent through the CAPWAP tunnel. When they are connected to the controller, they can also send traffic back to the controller.
  • What is Flexconnect?

    FlexConnect is a solution for branch office and remote office deployments. It enables customers to configure and control access points in a branch or remote office from the corporate office through a wide area network (WAN) link without deploying a controller in each office.
  • What is a controller based access point?

    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.
C.

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.
  • What is the access point?

    In computer networking, a wireless access point (WAP), or more generally just access point (AP), is a networking hardware device that allows a Wi-Fi device to connect to a wired network. An AP is differentiated from a hotspot, which is the physical location where Wi-Fi access to a WLAN is available.
  • What is the difference between an access point and a bridge?

    A wireless access point is a device that extends a wired network, into the wireless space - it will have an Ethernet port to connect to the wired network, and radio transceivers to connect to wireless devices. A wireless bridge is an arrangement of devices (minimum two) that link two wired network segments, wirelessly.
  • What is the bridge mode on a router?

    Setting your Linksys Smart Wi-Fi Router to Bridge Mode is applicable when you want to: Connect two (2) routers with the capability of sharing the network resources. Use the router as an additional access point on an existing network. Connect the router to a modem/router from your Internet Service Provider (ISP)
