AP-LOCAL DYNAMIC SWITCHING

摘要

A technique for implementing AP-local dynamic switching involves Layer 2 switching. This may be accomplished by providing data associated with wireless stations to an AP sufficient to enable the AP to determine whether traffic from a particular wireless station should be locally switched. Alternatively, the wireless station may be able to determine whether to locally switch traffic based upon the traffic itself. For example, it may be desirable to AP-locally switch voice traffic to avoid latency, which is particularly detrimental to voice transmissions such as voice-over-IP. Traffic that is not to be switched locally is Layer 2 tunneled upstream.

1. An apparatus, comprising:
a processor coupled to a memory and that is configured to execute a dynamic switch, the dynamic switch implemented in a non-transitory computer readable medium, and configured to be coupled to a radio and a station switching record (SSR) database storing an SSR associated with a first wireless station that is operatively coupled to an access point (AP) that defines a first virtual access point and a second virtual access point; the dynamic switch configured to send a signal such that (1) based on the first wireless station being operatively coupled to the first virtual access point, traffic received by the radio from the first wireless station is Layer 2 (L2) switched locally via the first virtual access point to a second wireless station connected to the AP, and (2) based on the first wireless station being operatively coupled to the second virtual access point, the traffic received by the radio from the first wireless station is L2 tunneled upstream via the second virtual access point to the second wireless station.
