  • Patent number: 8665882
    Abstract: A system comprises a plurality of nodes; and a hub that is communicatively coupled to each of the plurality of nodes via a plurality of point-to-point links, wherein a priority-based arbitration scheme is used by the plurality of nodes and the hub to communicate over each of the plurality of point-to-point links. When the hub determines that one or more of the plurality of nodes is each transmitting a message having an identification field comprising a first sub-field and a second sub-field, the hub uses the first sub-field to select which node's message should be forwarded to the other nodes based, at least in part, on the priority-based arbitration scheme and forwards the selected node's message as it is received to the other nodes, continuing with the second sub-field of the selected node's message.

  • Patent number: 8659993
    Abstract: Embodiments of the invention describe apparatus, systems and methods for creating a protection switching domain having a control virtual local area network (vlan), a first set of high priority protected data vlans, and a second set of lower priority protected data vlans. When a fault is detected at a ring network, indicating a failed link between adjacent nodes, said fault is communicated to a master node of the ring network via the control vlan. Embodiments of the invention allow a user to specify a priority for each of its domains on a given set of ring ports. The higher priority protected data domains are serviced to completion prior to servicing the lower priority protected data domains, ensuring that data traffic convergence time does not increase across these vlans.

  • Patent number: 8649493
    Abstract: When making a decision about who should have control of a voice channel in a teleconference, one exemplary aspect is directed toward a voice switch mechanism that determines and takes into account a latency (such as a round trip latency) of each participant's path to the switch. The switch uses this information to ensure that short-latency paths do not have an unfair advantage over long-latency paths when individuals competitively seek control of the voice channel. Illustratively, if an individual is participating in the path that has a round trip latency of 300 ms or greater than that of other participants, the voice switch creates a level playing field even if it detects voice energy from a short-latency user first by granting control of the channel to the long-latency user if voice energy is detected from that user within 300 ms of the short-latency detection.

  • Patent number: 8582579
    Abstract: A network node in a vehicular network processes packets based on a prioritization scheme. The prioritization scheme uses packet type, priority, source, destination, or other information to determine a priority of the packets. Packets can be stored in one of multiple queues organized according to packet type, or other criteria. In some cases, only one queue is used. The packets are time stamped when put into a queue, and a time to live is calculated based on the timestamp. The time to live, as well as other factors such as packet type, packet priority, packet source, and packet destination can be used to adjust a packet's priority within the queue. Packets are transmitted from the queues in priority order. In some cases, the network node can identify a top-priority packet, and transmit the top priority packet without first storing the packet in the queue.

  • Patent number: 8547840
    Abstract: Bandwidth is allocated by leveraging a bursty characteristic of data transmission signals to efficiently utilize network resources. Network performance is observed over a time period to identify patterns of data transmission rates as different signals are processed. To compensate for the fact that different jobs/tasks peak at different times, the total bandwidth limit may be increased by a scaling factor. The scaling factor is calculated using information obtained by observing network performance during the time period. The scaling factor is used to increase the total bandwidth available for all jobs/tasks executing during the time period without exceeding any bandwidth limits. The data transmission rate of each job/task may then be adjusted to utilize the newly available bandwidth.

  • Patent number: 8509242
    Abstract: The present invention involves traffic management in a communication system (1) comprising multiple communication terminal (10, 200) that each has data flows presented in transmit buffers (14, 220). The terminals (10, 200) utilize a default priority scheme for selecting data from the buffers (14, 220) to transmit at transmission occasions determined by a schedule scheme. A switching event is detected based on information of an estimate distribution of data flows in a first portion (2) of the system (1). A priority scheme update message is generated based on this event detection. The update message comprises information of a temporary priority scheme that is to be used by terminals (10, 200) in a second portion (2; 5) of the system (1). By using this temporary scheme that assigns new temporary priorities to the data flows, a local shaping of the transmission pattern and data flow distribution in the second system portion (2; 5) is possible.

  • Patent number: 8462631
    Abstract: Systems and methods for dynamically controlling bandwidth of connections are described. In some embodiments, a proxy for one or more connections may allocate, distribute, or generate indications of network congestion via one or more connections in order to induce the senders of the connections to reduce their rates of transmission. The proxy may allocate, distribute, or generate these indications in such a way as to provide quality of service to one or more connections, or to ensure that a number of connections transmit within an accepted bandwidth limit. In other embodiments, a sender of a transport layer connection may have a method for determining a response to congestion indications which accounts for a priority of the connection. In these embodiments, a sender may reduce or increase parameters related to transmission rate at different rates according to a priority of the connection.

  • Patent number: 8451721
    Abstract: An improved solution for managing messages through a request response protocol network utilizing a path-based adaptive prioritization and latency management is provided. A weight for a message is determined at a message management computing device based upon a number of hops and a latency of networks passed through by the message. A hop latency target for a current hop segment is evaluated relative to an overall latency target and the determined weight for the message. A priority of the message is adjusted in response to determining that the overall latency target, relative to the weight for the message and the hop latency target for the current hop segment, exceeds a configured allowable hop latency deviation for the current hop segment.

  • Patent number: 8446845
    Abstract: An auditing function detects and corrects reservation and routing topology map errors by monitoring the operation of an advanced bandwidth manager (ABM). A session/call admission controller (S/CAC) attached to a network manages loading with policy enforcement points (PEP's) when the network nears or exceeds its capacity. Ever-changing network topology information is monitored, modeled, and analyzed from remote listeners. A correct model of how traffic is being routed through various parts of the network is critical to admission control. The PEP's at the network edges provide short-term, application-aware controls on their own that are applied to the corresponding network ingress traffic. The S/CAC uses the path tables to calculate whether particular PEP's can admit more traffic, or should they shed sessions/calls to keep service up for the existing application traffic. Long-term controls are periodically downloaded as admission tables from the S/CAC to the PEP's.
