Abstract: In one embodiment, a time period is identified in which probe packets are to be sent along a path in a network based on predicted user traffic along the path. The probe packets are then sent during the identified time period along the path. Conditions of the network path are monitored during the time period. The rate at which the packets are sent during the time period is dynamically adjusted based on the monitored conditions. Results of the monitored conditions are collected, to determine an available bandwidth limit along the path.

Otherwise, if the status of one or more segments is within a second range, a determination as to whether the originating trunk and terminating segment can operate at a second data rate may be made, and, if so, the call may be established over the transmission path between the originating call device and terminating call device at the second data rate.

Abstract: A transmission system can improve transmission efficiency of a wireless link using multi-TID aggregate frames. The system can receive a block acknowledgement from a destination device, in response to sending a first multi-TID aggregate frame to the destination device via a wireless link.

If the system determines that the packet error rate for the respective TID is greater than a predetermined threshold, the system can reserve a number of packet slots in a second aggregate frame for duplicate packets of the respective TID. The system may then generate the second multi-TID aggregate frame that includes duplicate packets for the respective TID in the number of reserved packet slots, and can send the second multi-TID aggregate frame to the destination device via the wireless link.

Abstract: A method of sub-channel independent network allocation vector (NAV) management by a wireless station (STA) in a wideband wireless communications system is proposed. In the wideband system having multiple sub-bands, each NAV for a corresponding sub-band is independently managed. The protection duration for each NAV is independent for each sub-band and the threshold or update rule for NAV modification is also independent for each sub-band. The threshold or update rule for NAV modification may also be different when the NAV is generated or propagated by an OBSS STA. Furthermore, early termination of NAV is allowed if the NAV is set by an OBSS STA only.
