10151 results about "Transmission rate" patented technology

Transmission rate - Computer Definition. The theoretical rate at which user data can be transmitted across a circuit. The signaling rate is the total data rate, including overhead, i.e., signaling and control information.Therefore, the transmission rate is always less than the signaling rate.

Method and system for rate control service in a network

A system and method has been disclosed for controlling the transmission flow rate of data bits in a data bit transfer session from a serving entity to a client, the session involving bit transfer over a wireless communications link, the method comprising: setting up the session, included establishing the addressing, by providing a radio control node to establish flow rate parameters relating to the wireless link, monitoring the wireless communication link; based on monitoring, sending new flow rate parameters so that the serving entity can update the transmission rate of the session in accordance with the new rate control parameters.

System and method for traffic shaping based on generalized congestion and flow control

A system and methods are shown for traffic shaping and congestion avoidance in a computer network such as a data-over-cable network. A headend of the data-over-cable system includes a traffic shaper configured to calculate a packet arrival rate from a cable modem and a traffic conditioner configured to calculate an average queue size on an output interface to an external network. For example, the traffic shaper compares the packet arrival rate to three packet arrival thresholds including a committed rate threshold, a control rate threshold and a peak rate threshold. If the calculated packet arrival rate falls between the committed threshold and control rate threshold, the traffic shaper applies a link layer mechanism, such as a MAP bandwidth allocation mechanism, to lower the transmission rate from the cable modem.

Fibre channel switch

A Fibre Channel switch is presented that tracks the congestion status of destination ports in an XOFF mask at each input. A mapping is maintained between virtual channels on an ISL and the destination ports to allow changes in the XOFF mask to trigger a primitive to an upstream port that provides virtual channel flow control. The XOFF mask is also used to avoid sending frames to a congested port. Instead, these frames are stored on a single deferred queue and later processed in a manner designed to maintain frame ordering. A routing system is provided that applies multiple routing rules in parallel to perform line speed routing. The preferred switch fabric is cell based, with techniques used to manage path maintenance for variable length frames and to adapt to varying transmission rates in the system. Finally, the switch allows data and microprocessor communication to share the same crossbar network.

Method and apparatus for communication network cluster formation and transmission of node link status messages with reduced protocol overhead traffic

The present invention facilitates cluster formation within a communications network by utilizing network topology information to designate network nodes that are crucial for relaying traffic as cluster head nodes, while remaining network nodes are designated as member nodes. A beacon packet transmission rate of a network node or the interval between successive beacon packet transmissions by that node is adjusted by the present invention to facilitate cluster formation independent of network size and varying initial start times of network nodes. In addition, the present invention utilizes the above described cluster formation technique to form a three tier architecture for transmission or flooding of routing information from head node databases throughout the network. The cluster formation technique is applied to cluster head nodes to form an additional network tier of super nodes that distribute routing information, while cluster head nodes route network data traffic. The databases of cluster head nodes are examined subsequent to flooding of head node database information by super nodes, where data missing from a head node database is requested from a corresponding super node, thereby eliminating transmissions of acknowledgment messages.
