Quality of service packet scheduler design
Systems, methods, devices, and processors are described for quality of service (QoS) packet scheduling in satellite communications systems. A packet received at the QoS packet scheduler may be assigned a virtual departure time utilizing novel self-clocked fair queuing techniques. The virtual departure time for a packet assigned to a queue may depend on a different weight assigned to the queues. Queues may be treated as low latency queues in some cases and may be provided with committed information rates in other cases. Low latency queues may be assigned weights equal to infinity, or the reciprocal of the weight equal to zero. Queues with committed information rates may assign different weights to packets depending on whether the rate that packets are received exceeds the committed information rate. Packets may then be scheduled based on their virtual departure time order. |

Methods and apparatus for using multiple connection identifiers based on traffic requirements
Methods and apparatus related to scheduling and/or utilization of air link traffic resources are described. A peer to peer connection holds a set of multiple connection identifiers for a plurality of successive traffic slots. Corresponding to a particular traffic slot, each of the connection identifiers in the set of connection identifiers has a different priority. Short term traffic needs are considered in the use of the multiple connection identifiers being held. For example, a communications device, corresponding to a peer to peer connection which is associated with a plurality of connection identifiers having different priorities, considers the amount and/or latency requirements of data to be transmitted at any given time when selecting which connection identifier to use when transmitting a traffic transmission request for a traffic segment which is in contention. |
