The data to regular devices can be directly sent out in MAC layer. However, the data to polling device needs to be queued until polling request is received.
My question is how the router knows which packet should be going to polling device and which packet can be directly sent out to none-polling packet.
Dose router maintain a table for every device to differ whether it is a polling end device or none polling device?
Thanks

Usually End Devices are defined as polling devices, where routers are non-polling devices.
By saying usually I mean if one doesn't make any changes to the Stack on End Device side
