Abstract
A system, method, and apparatus for maintaining the status of communications between a wireless client and a content source is presented herein. During periods where the wireless link at the wireless client has deteriorated, a wireless content switch prevents timers at the content source from expiring by transmitting an acknowledgment message to the content source. The acknowledgement also stops the content source from transmitting data packets to the wireless client by indicating a zero window size. Additionally, during the time period that the wireless link to the wireless client is deteriorated, the wireless content switch responds to communications from the content source for the wireless client.
