摘要： A method for controlling congestion of traffic, by one of one or more User Terminals (UTs), traversing an intermediate node, the method comprising: associating one or more traffic flows of a priority to one of the one or more UTs; detecting a traffic congestion for the priority; performing Random Early Detection (RED) congestion control for the priority to relieve the traffic congestion; selecting, for the priority, a User Terminal (UT) with a perceived delay greater than a high threshold; and controlling, by priority, the traffic flows associated with the selected UT.

摘要： A method and system for distributive flow control and bandwidth management in networks is disclosed. The method includes: providing multiple Internet Protocol (IP) Gateways (IPGWs) that each have a maximum send rate and one or more sessions with associated throughput criteria, wherein each IPGW performs flow control by limiting information flows by the respective maximum send rate and throughput criteria; providing multiple Code Rate Organizers (CROs) that each have a bandwidth capacity, wherein each CRO performs bandwidth allocation of its respective bandwidth capacity to one or more IPGWs of the multiple IPGWs; interconnecting the multiple IPGWs with the multiple CROs; and performing bandwidth management across the multiple CROs and IPGWs. In the method, an IPGW of the multiple IPGWs provides flow control across a plurality of the CROs of the multiple CROs, and a CRO of the multiple CROs allocates bandwidth to a plurality of the IPGWs of the multiple IPGWs.

摘要： A shared bandwidth network system to communicate network traffic between terminals and an external network is disclosed. The system includes: a point of presence (POP) for the external network; Radio Frequency Gateways (RFGWs) wherein each RFGW of the RFGWs provides one or more Radio Frequency (RF) paths, and each of the RF paths links a respective RFGW of the RFGWs with one or more terminals of the terminals; an RF path state manager to manage a RF path state for each of the RF paths; a Satellite Network Core (SNC); a Software Defined Network (SDN) controller to maintain a topology based on the RF path states, wherein the topology includes the POP, the RFGWs and the SNC; and a network layer to route network traffic between the POP, the RFGWs and the SNC based on the topology. The SNC includes a bandwidth manager to allocate bandwidth, to provide flow control to the terminals, and to provide a key state including a bandwidth allocation for each of the terminals, a key state manager to maintain the key states, and a link layer control (LLC) to transport network traffic over each of the RF paths.

摘要： An approach is provided for providing quality of service reservations in a packet-based radio communication network is disclosed. Connection information including connection rate is extracted from a dataflow from an application requesting connection-oriented service. A request message is sent to a proxy for establishing a connection based on the connection information over the network, wherein the proxy configures a classification rule based on flow criteria from the request message and accordingly initiates establishment of the connection over the network to a destination terminal. A confirmation that the connection can be established is selectively received according to the connection information, wherein the dataflow satisfying the flow criteria from the application is transported over the established connection to the destination terminal. This approach as particular applicability to shared capacity systems, such as a satellite communication system.
