Trigger frames adapted to packet-based policies in an 802.11 network
摘要
說明書
It is for the AP to assign a RU traffic type to each RU of the TT trigger frame based on the part of each traffic type in the overall traffic. A trigger frame profile may thus be generated and adapted, later on, as the network traffic evolves (due to evolving traffic requirements such as the latency of each data traffic);
-
- a queue size associated with each traffic type representing the sum of all corresponding traffic waiting to be sent by all the nodes.
As known in the 802.11 standard, the MAC header of the send packet includes a “Queue Size” field indicating the amount of buffered traffic for a given traffic type that is waiting in the transmitting node. Based on such information, the AP is able to compute global statistics on total queue size for each of the predefined traffic types, a total queue size for a predefined traffic type summing the sizes of transmission queues that are associated, in the nodes, with the predefined traffic type. The AP may then build an associated TT trigger frame defining RUs with dedicated traffic types.
Next to step 1001, step 1002 uses the statistics to dedicate one or more RUs to respective specific RU traffic types.
