A thermostat control system having remote devices and / or other internally powered devices provides transmissions at different power levels and at different data transfer rates to conserve power life. Thermostat control system components and devices may be powered by replaceable power supplies that are conserved by transmitting at a lower power level more often than at a higher power level. A higher power level transmission is provided at a lower data transfer rate, and a lower power level transmission is provided at a higher data transfer rate. A higher power transmission is provided periodically to ensure reliable communication of temperature information.

A network switch includes network switch ports, each including a port filter configured for detecting user-selected attributes from a received layer 2 frame. Each port filter, upon detecting a user-selected attribute in a received layer 2 frame, sends a signal to a switching module indicating the determined presence of the user-selected attribute, for example whether the data packet has a prescribed priority value. The network switch includes a flow control module that determines which of the network switch ports should output a flow control frame based on the determined depletion of network switch resources and based on the corresponding priority value of the network traffic on each network switch port. Hence, any network switch port that receives high priority traffic does not output a flow control frame to the corresponding network station, enabling that network station to continue transmission of the high priority traffic. In most cases, the congestion and depletion of network switch resources can be alleviated by sending flow control frames on only those network switch ports that receive lower priority traffic, enabling the network switch to reduce congestion without interfering with high priority traffic.

A packet transmission method for transmitting packets classified according to a quality of service (QoS) requirement from a transmitting node to a receiving node is provided. In the transmitting node, the steps of: selecting sequentially a QoS class; dividing a queued packet to be transmitted belonging to the selected class into a plurality of predetermined data units, and transmitting one of the obtained predetermined data units; and applying a transmitter-side retransmission control process to the data unit to be transmitted when the selected class is a QoS class specified for data type packets are provided. In the receiving node, the steps of: receiving sequentially the data units transmitted from the transmitting node; assembling a plurality of received data units to decompress the original packet for each QoS class; and applying a receiver-side retransmission control process to the received data units to be assembled when the received data unit belongs to one of the QoS classes specified for the data type packets are provided.
