Primary Discovery Request Message Deletion of Protected Records A single Receiver thread receives and processes any requests from APs.

To provide an extensible protocol that is not bound to a specific wireless technology. Third, monitoring the status of both hardware and software configurations is necessary to ensure a properly operating network. It is important to realize that the definition of what a controller is is not clearly defined.

Once the AP has received the configuration, it may enter the Run state. Distribution of this memo is unlimited. There are two types of threads that may be instantiated on the controller: However, this simplicity does not come at the expense of flexibility.

Overall convergence for the APs to come online will take longer in this scenario. Vendors do not have a clearly defined set of protocols that must be implemented, in order efc be compatible with other vendors. Table of Contents 1. Fit APs are a combination of the Thin and Thick metaphors.

Overview of CAPWAP (Cisco Wireless LAN Controllers)

Often refered to as remote antennas, Thin APs lower price allow for a more thorough wireless coverage at a given price point, and are attractive offerings for capqap deployments. A device that contains an interface to a wireless medium WM.

Once received, the controller moves to the Acquiring phase without responding yet. Instead, SLAPP proposed a generic protocol for an AP style device to seek out a controller, and establish an encrypted connection, over which a protocol would be agreed upon, and carried out. In that case, the AP would take longer to join because the code versions would obviously be different.

Current Status and Overview of the CAPWAP Protocol

The security model is not ported over from LWAPP, as there were many concerns about the validity of the security. LWAPP defines certain operation modes for compliant hardware. Major vendors have also expressed doubt over the demand from customers for interoperable WLAN infrastructure.

A controller must respond with a Discovery Response. Split and Local MAC medium access control.

The controller then authenticates the AP, and begins uploading firmware to the AP. Thus, the entire process of deploying an AP can be implemented in a vendor neutral format, from finding an initial controller, to deploying firmware updates, to configuration and access point redirection. Because SLAPP supports both layer 2 and 3, access points may be in completely different routed networks as the controller, or even across the Internet. The publishers argue that an unencrypted data channel is not a security threat, because full IPsec is available.

Because the AP relies on the controller for its MAC layer, it is sensible to extend this to tfc to firmware and configuration as well.

In this regard, the controller acts in similar fashion to a router, by accepting and processing layer 2 frames, and then switching layer frames on to the access network. Securing – This phase establishes an encrypted cwpwap, over which a protocol can be agreed upon. Meru Air Traffic Control software may be used to provision and manage APs, but provides no multi vendor support. More specifically, it fails to define key duties mentioned in [Section 2. As shown in Figure 1the wireless frames received from a mobile device, which is referred to in this specification as a Station STAare directly encapsulated by the WTP and forwarded to the AC.

The state machine in [fig6] show the 4 states attainable during protocol negotiation by a device.
