Systems for and methods for queue management for latency control

A system comprising:

• a latency controller on a device in communication with a first queue for a lower priority channel and one or more second queues for one or more higher priority channels to communicate packets, each of the one or more second queues associated with a latency budget based at least on a type of application;
• wherein the latency controller is configured to:
• receive a plurality of packets of a plurality of flows, each of the plurality of packets including an arrival time stamp, using a higher priority channel and the lower priority channel to communicate packets from each of the plurality of flows, the lower priority channel using the first queue to queue packets for transmission of lower priority packets and the higher priority channel using the one or more second queues, each having the latency budget based at least on the type of application, for transmission of higher priority packets;
• classify, based at least on the type of application, each of the plurality of flows for transmission as either higher priority via the one or more higher priority channels or lower priority via the lower priority channel;
• determine for packets for each of the plurality of flows classified as higher priority, a queue of the one or more second queues to use for transmission and a departure time stamp for each of the packets according to the latency budget for the type of application;
• and
• communicate each of the higher priority packets with the departure time stamp to a corresponding queue of the one or more second queues based at least on the type of application, wherein a transmission scheduler prioritizes transmission of packets from the one or more second queues based at least on the departure time stamp.

A system comprising:

• a network device in a computing environment of a first network, the network device providing access to the Internet and one or more second networks to one or more devices in the computing environment of the first network;
• a latency controller on the network device configured to:
• identify an arrival time stamp for packets for a plurality of flows being communicated to the one more devices;
• classify, based at least on a type of application, each of the plurality of flows for transmission as either higher priority or lower priority;
• determine for packets of each of the plurality of flows classified as higher priority, a departure time stamp for each of the packets according to a latency budget for the type of application;
• and
• communicate each of the higher priority packets with the departure time stamp to a corresponding queue of one or more queues based at least on the type of application for transmission according to the departure time stamp.
