Providing multiple retransmission policies for a single data stream by mapping differentiated services code point (DSCP) bit fields to media access control protocol data unit (MPDU) bit fields
Abstract:
One feature provides for a method operational at an access point in communication with a destination station where the access point receives a stream of data including at least one media access control protocol data unit (MPDU) having a Differentiated Services Code Point (DSCP) field value, provides a retransmission policy to the MPDU based on the DSCP field value, and transmits the MPDU to the destination station via a wireless local area network. The stream of data may include a stream of video data having a layered modulation scheme, where the DSCP field value identifies at least one layer of the layered modulation scheme. The access point may use deep packet inspection to retrieve the DSCP value from the MPDU. In this fashion, multiple retransmission policies may be provided for a single data stream by mapping DSCP field values to MPDU bit fields, such as the Traffic Identifier field.
