Abstract
An access controller is coupled to an access point and receives data packets from connected user equipment. The access controller is configured to perform packet inspection techniques on the received packets to determine if they should be locally switched. In some embodiments, packets destined for a local intranet services may be locally switched to avoid congesting a core network link. In further embodiments, a local connection to the Internet may be used so that locally switched packets can also be directed to the Internet without the use of a core network link. In still further embodiment, in addition to packet inspection techniques, the access controller maintains a state table for the states of connected user equipment. The access controller may use the information in this table to further decide whether to perform local switching techniques.
