The duration of the sleep interval is the duration of a long preamble less the sum of two times the preamble detection interval plus the preamble processing interval. Phase lock loop (PLL) power is applied a PLL settling time prior to and during the preamble detection interval.

Abstract: A source node may send a first data unit to a destination node. To send the first data unit, the source node may transmit a modulation pattern over a transmission medium. In some cases, particular data units may correspond to modulation patterns with features that cause errors in transmission.

The alteration may result in the retransmission data unit corresponding to a modulation pattern different from that of the first data unit. The new modulation pattern may lack the error causing features and reduce the chance of repeated errors.

Abstract: Techniques whereby a LAN-side border router observes all packets of an application flow from both directions so that the application recognition performed on the LAN-side border router functions properly. A border router may implement flags in a flow cache to indicate whether the border router is the LAN-side border router and/or a WAN-side border router for an application flow. As packets are received at a border router at either the LAN interface or WAN interface, the flags associated with packet's application flows are examined to determine if the border router is the LAN-side border router for the application flow. If so, then application recognition and routing control may be performed. If not, the packet may be redirected to another border router that may be the LAN-side border router or the WAN-side border router for the application flow to insure that border router observes the packet.
