An admission controller and its method of operation for controlling admission of data flows into an aggregate data flow are described. Admitted data flows are aggregated into an aggregate data flow for transmission by a router, for example, over a data network. The aggregate data flow typically follows a pre-established path through the network; for example a multi-protocol label switched (MPLS) path. The path has minimum and maximum bandwidth limits assigned to it. The admission controller controls admission of new data flows into the aggregate data flow by granting or denying new session requests for the new data flows. Congestion notifications received from the network and bandwidth limits of the path are considered in determining whether to grant or deny a new session request. In this way, the admission controller provides elastic sharing of network bandwidth among data flows without exacerbating network congestion and while remaining within the path's bandwidth limits. The data flows may include transaction oriented traffic.

A method and system for controlling traffic on a network. A congestion indicator is generated by network components in response to the flow of network traffic. The congestion indicator is received by a network peripheral node that has a threshold variable which controls the flow of traffic flowing from the network peripheral node. The threshold variable corresponding to the congestion indicator will be reduced in order to restrict the flow of traffic flowing from that network peripheral node. If more than one congestion indicator is received by the network peripheral node, then the threshold variable will continue to be reduced thereby further restricting network traffic. If no further congestion indicators are received, then the network peripheral node will terminate the Back-Off Period state of the threshold variable such that the threshold variable can then be increased and network traffic can increase.

Provided are a system and method for informing a vehicle accident using a telematics device. In an emergency, such as vehicle collision, etc., the system and method propagate information on the accident to vehicles around the accident scene, thereby informing the vehicles of traffic congestion. Since the vehicles continuously inform the same to vehicles behind through ad-hoc communication, a vehicle guided by a telematics device can recognize the traffic congestion ahead, re-search for a path, and thereby make a detour. Therefore, although vehicles behind the accident scene cannot see the occurrence of the accident on a foggy highway, etc., the risk of a chain-reaction crash is reduced. In addition, it is possible to avoid traffic congestion due to an accident in downtown.

A route processor computes a plurality of travel routes using map information on the basis of current-position information and destination information. A travel route is set according to VICS data and traffic-congestion prediction information obtained by statistically processing the past traffic condition based on time factors, and a vehicle is navigated on the travel route. When it is determined that there is a change in travel smoothness such as a congested traffic or a heavy traffic on the travel route, the required time for the travel route and detouring travel routes is computed, and percentage is computed so that travel routes with shorter travel time have higher chances to be selected, thereby generating weighting information. On the basis of the weighting information, one of the travel routes is notified. The required time for the respective travel routes can be substantially equalized and thus preventing the concentration of heavy traffic-congestions only on certain roads. Therefore, the navigation for a smooth travel for vehicles in a stable traffic condition can be easily provided.

An automated traffic control system provides real time alternative traffic flow solutions to address traffic congestion on a roadway. A process will pick routes to scan for real-time statistics on the traffic conditions and calculate an average vehicle speed (AVS) for that route, road, highway, etc. If the AVS drops below a historical threshold, a decision matrix is created, whereby all the real-time data is compared with historical data and provides an ideal or best alternative route for “route X”. The operator is provided this information within seconds and is allowed to make a decision to “accept pr decline” the proposed changes in routes. If the proposed changes are accepted, the changes begin to occur automatically such as but not limited to updating electronic signage, changing traffic control signals (all green to keep traffic moving), moving electronic barriers, etc.

A novel and useful apparatus for and method of handling traffic congestion during power save mode in client / server systems such as wireless local area networks (WLANs). A reduction in response time is achieved by minimizing communications between the host and the MAC processing entities in client devices. The host sends shortened descriptors to the MAC rather than complete frames. Only a limited number of frames for each client queue are stored on the MAC. A transfer bitmap is used to track the frames to be transferred from the host to the MAC. Transmitter pre-processing is performed on the frames pulled from the host. A transmit bitmap is used to track frames that have been processed and awaiting transmission to a client. Frames that are ready are then sent out from queues for clients that are active and have an ongoing service period.
