Preemptive packet transmission

Disclosed herein is technology to reduce latency of frames through a network device supporting various priorities. In an implementation, a method comprises configuring one or more priorities with a preemptive right over other one or more of said plurality of priorities; receiving frames in a sequence, each of the frames having a frame priority comprising of one of said plurality of priorities; queuing the received frames in a predetermined order based on a frame arrival time and the frame priority; transmitting a current frame based on a current frame priority and current frame arrival time; stopping transmission of the current frame when a later frame in the sequence is received that has a later frame priority with preemptive right over the current frame priority; transmitting an invalid frame check sequence; transmitting the later frame; and restarting the transmission of the current frame after transmitting the later frame.

USER DIRECTED BANDWIDTH OPTIMIZATION

Systems and methods are provided to optimize bandwidth usage associated with a local network. As part of the bandwidth optimization techniques, an authentication entity may receive an indication of an access profile selected by a user of an electronic device. The authentication entity may assign the access profile to the electronic device. Accordingly, when the electronic device transmits data, a network regulation entity may process the traffic in accordance with the access profile. To this end, the network regulation entity may correspond communication sessions within the traffic to an application. The network regulation entity may then query the access profile to determine a priority for each application. When the traffic exceeds a threshold byte volume, the network regulation entity may queue lower priority communication sessions. By processing the traffic based upon a user-indicated access profile, compliance with network neutrality principles may be maintained.
