1. An Extended Service Set (ESS) comprising:
a port in communication to a backhaul network;
a switch in communication to the port;
two or more Stations (STAs);
an Access Point (AP) in communication with the switch and the two or more STAs, the AP operable to:
analyze a bandwidth restriction in a communication stream of the AP, wherein the bandwidth restriction is associated with a port in communication with the AP, wherein the bandwidth restriction associated with the port comprises a determined port capacity, wherein the determined port capacity is a difference between a port capacity and non-wireless traffic overhead, and wherein the port capacity comprises a product of a switch capability multiplied by a capacity allowed by a Software Defined-Wide Area Network (SD-WAN) policy enforced by a user, wherein the bandwidth restriction is associated with a network to which the AP belongs and wherein the bandwidth restriction associated with the network comprises a link hop bandwidth or a stream inflow bandwidth and wherein the bandwidth restriction is associated with a backhaul network in communication with the AP;
based on the bandwidth restriction, determine a lower amount of wireless bandwidth to provide to at least one of the two or more STAs wirelessly communicating to the AP; and
modify a bandwidth allocation assigned to the at least one of the two or more STAs based on the lower amount of wireless bandwidth wherein modifying the bandwidth allocation comprises reducing a number of spatial streams used by the AP based on the bandwidth restriction or modifying the Resource Unit (RU) allocation provided to the at least one of the two or more STAs based on the bandwidth restriction wherein the bandwidth restriction is associated with an egress capacity of the AP wherein the egress capacity is a difference of, a product of Ethernet port capacity, of the AP, multiplied by a Link Aggregation data (LAG), minus an amount of 802.11 Management traffic overhead.
