Abstract: A method and apparatus for selectively accelerating network communications provides improved operation of network communications through channels with long delays, such as a satellite communications channel. A configuration management mechanism provides a selection of acceleration configuration for particular addresses of devices that may communicate through the communications channels. Acceleration may be bypassed for particular addresses or classes of devices within the network and priorities may be assigned, permitting a cut-off of acceleration when a threshold number of sessions is reached. The method and system may also allow a higher priority class of session to preempt lower priority session by removing resources from the lower priority session and assigning them to the higher priority session. The data rate of the lower priority session is then lowered (due to the absence of acceleration or reduced buffer size) to reduce traffic flow.

Abstract: A network system with a STAR topology allows single hop connectivity between sites. The system has a hub site and a plurality of remote sites. A first channel is used for sending data from the hub site to all of the plurality of remote sites. A plurality of second channels are used for transmitting data from each of the plurality of remote sites to the hub site and for transmitting data between the plurality of remote sites. In the system, call control and management between the hub site and the remote sites and between different remote sites use Internet protocol (IP) addressing for identification.
