An approach for transmitting packets over a shared communication channel is disclosed. A satellite terminal (ST) () contains a processor that transmits a packet over a transmission slot of the channel using a contention protocol, such as persistent Aloha. The processor reserves an available transmission slot, which is maintained until expiration of a predetermined timeout period.

Method and system for providing efficient data transmission based upon a contention protocol

An approach for processing packets for transmission over a satellite communications network is disclosed. A communication system includes a satellite terminal that provides connectivity for a host. The satellite terminal includes a user interface that receives a packet associated with an application from the host, and classification logic that classifies the packet into one of a plurality of transport services based upon the corresponding application. The satellite terminal also includes a mapping logic that maps the one transport service to one of a plurality of packet delivery services, wherein the one packet delivery service provides transmission of the packet to the satellite. The system also includes a hub that is configured to communicate with the satellite terminal over the satellite to provide the plurality of packet delivery services.

Method, apparatus, and system for identifying and efficiently treating classes of traffic

An approach for transmitting packets conforming with the TCP (Transmission Control Protocol) over a satellite communications network comprises a plurality of prioritized queues that are configured to store the packets. The packets conform with a predetermined protocol. A classification logic classifies the packets based upon the predetermined protocol. The packet is selectively stored in one of the plurality of queues, wherein the one queue is of a relatively high priority. The packet is scheduled for transmission over the satellite communications network according to the relative priority of the one queue.

Low latency handling of transmission control protocol messages in a broadband satellite communications system

An approach for allocating system capacity of a communication switching system for exchange of traffic is disclosed. The system includes multiple terminals that request allocations of system capacity. The capacity is partitioned into a provisioned portion and an unprovisioned portion, in which a portion of the terminals constitutes a pool having a plurality of sub-pools. According to one embodiment, a control computer communicates with the plurality of terminals and allocates the provisioned portion of the capacity to the plurality of sub-pools of the terminals. The provisioned portion of the capacity is arranged into sub-partitions, wherein one of the sub-partitions is not associated with the sub-pools of terminals. Remaining sub-partitions are associated with the sub-pools of terminals. The control computer selectively allocates available capacity from the sub-partitions to one of the sub-pool terminals to permit overflow of traffic from the one sub-pool terminal, and selectively allocates the unprovisioned portion of the capacity to the pool to permit overflow of traffic from a terminal within the pool and to a terminal that is not a part of the pool of terminals.
