Multicast With Wireless LAN Controllers (WLCs) and Lightweight Access Points (LAPs) Configuration Example

Tags:
local area networks (lan)

Overview This paper provides a configuration example on how to configure Wireless LAN Controllers (WLCs) and Lightweight Access Points (LAPs) for multicasting and communication with a multicast enabled wired network. Before Cisco Unified Wireless Network Software Release 3.2, when IP multicast was enabled, the controller delivered multicast packets to wireless LAN (WLAN) clients by making copies of the multicast packets, then forwarded the packets through a unicast Lightweight Access Point Protocol (LWAPP) tunnel to each access point (AP) connected to the controller. Each multicast frame received by the controller from a VLAN on the first hop router was copied and sent over the LWAPP tunnel to each of the APs connected to it.

Wi-Fi location system is better than GPS, says start-up

Using the unique identifier of the wireless router, it notes in the database where the access point is located. When a mobile user running the Skyhook client pops up in a neighbourhood, the software scans for access points.

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
