    摘要： Techniques for performing traffic classification for uplink and bi-directional traffic streams are described. A station receives packets for transmission on the uplink to an access point. The station identifies packets for each uplink traffic stream and packets for each bi-directional traffic stream based on at least one classification parameter for each traffic stream. The station sends packets for each traffic stream in accordance with at least one QoS parameter for the traffic stream. The access point receives packets for transmission on the downlink to at least one station. The access point identifies packets for each downlink traffic stream and packets for each bi-directional traffic stream based on at least one classification parameter for each traffic stream. The access point sends packets for each traffic stream in accordance with at least one QoS parameter for the traffic stream.

    摘要： A receiver for high-speed indirect synchronous digital data transmission includes an elastic buffer receiving an incoming data stream containing embedded timing information preceding a data sequence, generating a recovered clock from the timing information, initially synchronizing the frequency of a local clock to the recovered clock, and accommodating subsequent drift between the recovered and local clocks across the duration of the data sequence while tolerating clock jitter. Received data is clocked into a FIFO buffer within the elastic buffer based on the recovered clock and read out based upon the local clock, with the buffer expanding or contracting by adjustment of an index to accommodate skew of greater than one clock period. Expansion or contraction of the FIFO buffer is disabled during periods when clock jitter is likely, such as periods immediately following an index change.
