CCKM
Cisco Centralized Key Management (CCKM) is a form of Fast Roaming and a subset of the Cisco Compatible EXtensions (CCX) specification. When a wireless LAN is configured for fast reconnection, a Lightweight Extensible Authentication Protocol (LEAP) enabled client device can roam from one wireless access point to another without involving the main server Server may refer to: Computing *Server (computing), a computer program or a device that provides functionality for other programs or devices, called clients Role * Waiting staff, those who work at a restaurant or a bar attending customers and su .... Using CCKM, an access point configured to provide Wireless Domain Services (WDS) takes the place of the RADIUS server, and authenticates the client without perceptible delay in voice or other time-sensitive applications. The WDS (which can be run as a service on a Cisco Access Point or on various router modules) caches the user credentials after the initial log-on. The user mus ...

Cisco Compatible EXtensions
The Cisco Compatible Extensions (CCX) Specification describes a list of functional extensions to the IEEE 802.11 Wireless LAN standard to support fast roaming (CCKM) with upgraded security, reliability, and diagnostic performance. This specification is Cisco proprietary and a device manufacturer requires a Cisco license agreement in order to develop mobile devices with this technology. Currently, CCX versions 4 (CCXv4) and 5 (CCXv5) are supported. A working CCX network consists of one or more Cisco wireless access points, along with one or more CCX-enabled mobile devices. CCX is typically deployed in industrial, enterprise, or institutional environments where 802.11 wireless connectivity or reliability is extremely important. Typical deployments include barcode scanners in a warehouse, VoIP mobile phones in an office environment, and wearable medical devices that report patient status. The Cisco CCX license agreement does not include the software to actually implement CCX on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cisco
Cisco Systems, Inc., commonly known as Cisco, is an American-based multinational digital communications technology conglomerate corporation headquartered in San Jose, California. Cisco develops, manufactures, and sells networking hardware, software, telecommunications equipment and other high-technology services and products. Cisco specializes in specific tech markets, such as the Internet of Things (IoT), domain security, videoconferencing, and energy management with leading products including Webex, OpenDNS, Jabber, Duo Security, and Jasper. Cisco is one of the largest technology companies in the world ranking 74 on the Fortune 100 with over $51 billion in revenue and nearly 80,000 employees. Cisco Systems was founded in December 1984 by Leonard Bosack and Sandy Lerner, two Stanford University computer scientists who had been instrumental in connecting computers at Stanford. They pioneered the concept of a local area network (LAN) being used to connect distant compute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fast Roaming
IEEE 802.11r-2008 or fast BSS transition (FT), is an amendment to the IEEE 802.11 standard to permit continuous connectivity aboard wireless devices in motion, with fast and secure client transitions from one Basic Service Set (abbreviated BSS, and also known as a base station or more colloquially, an access point) to another performed in a nearly seamless manner. It was published on July 15, 2008. IEEE 802.11r-2008 was rolled up into 802.11-2012. The terms handoff and roaming are often used, although 802.11 transition is not a true handoff/roaming process in the cellular sense, where the process is coordinated by the base station and is generally uninterrupted. Rationale for the amendment 802.11, commonly known as Wi-Fi, is widely used for wireless local area communications. Many deployed implementations have effective ranges of only a few dozen meters, so, to maintain communications, devices in motion that use it will need to transition from one access point to another.
