  • Patent number: 10045247
    Abstract: A method and system for managing traffic in a network. For each label switch path of at least two logical switch paths, logical paths are identified. Each label switch path begins at a first provider edge and ends at a second provider edge. Most recent data received from the first provider edge is transmitted to the second provider edge via a selected logical path. For each logical path, jitter, packet delay and packet loss are identified. For each logical path, calculating a path usage is calculated as a first function of the jitter, the packet delay, and the packet loss, wherein the path usage is a fraction denoting a highest percentage of total network traffic that each logical path can manage.

  • Patent number: 9762495
    Abstract: A method, computer program product, and system for adjusting network traffic balance among a plurality of communication links between a first network node and a second network node on a computing network includes a processor receiving over a computing network from a network device, performance metrics for a plurality of communications links between a first network node and a second network node on the computing network and based on receiving the performance metrics, the processor determines degradation in network performance on at least one of the plurality of communication links. The processor determines a weight for each communication link, associating a lower weight with the degraded link(s), and formulates instructions for an adjusted network traffic balance among the links, based on the weights.

  • Patent number: 8811150
    Abstract: A method and computer system for dynamic error dampening in a node of a network system. Data traffic of the node is implemented in accordance with an Open Systems Interconnection (OSI) network management model that includes a Layer 1 physical link, a Layer 2 link including a data link in which primitive point-to-point data communication with neighboring nodes is enabled upon the Layer 1 physical link, and a Layer 3 link which is a network link operating on top of the Layer 2 link. Implementation of an error dampening process at the node includes deactivating the Layer 3 link of the node while monitoring data traffic over the Layer 2 link of the node. Deactivating the Layer 3 link of the node includes preventing the Layer 3 Link of the node from receiving incoming data traffic for routing to other nodes in the network system.

  • Patent number: 8422358
    Abstract: A system and associated method for dynamic error dampening in a node in a network system. The node collects statistics of data traffic transferred through the node. The node has a link error MIB storing Error ratio and Reliability of interface of the node. When the Error ratio is too high, the node starts running a Layer 2 protocol for monitoring data traffic and calculates Penalty of the node. When Penalty is higher than predefined Suppress Threshold, the node deactivates Layer 3 link while the Layer 2 protocol still monitors the interface. Once the Penalty becomes lower than Reuse Threshold, the node reactivates the Layer 3 link that had been previously deactivated. When Penalty becomes zero (0), the node clears the Error ratio and stops the Layer 2 protocol for monitoring the data traffic.

  • Patent number: 7983163
    Abstract: A method for implementing adaptive load sharing to balance network traffic. The method begins by identifying all paths in a network between a first provider edge and a second provider edge. Next determining jitter, packet delay, and packet loss for each identified path in the network. Then utilizing the jitter, packet delay, and packet loss values, calculating a usage value for each path in the network. The usage value corresponds to the percentage of all network traffic which a specific path in the network may manage. When data is received by the first provider edge, the provider edge selects the appropriate path for the data. The appropriate path being the path with the largest usage value which is currently not managing a percentage of the network traffic that is equal to its usage value.

    Abstract: A method and system for managing traffic between a first provider edge and a second provider edge in a network. The network includes logical paths between the first provider edge and the second provider edge. For each logical path, jitter, packet delay, and packet loss are identified. For each logical path, a path usage is calculated as a function of the identified jitter, packet delay, and packet loss. Most recent data received by the first provider edge is transmitted to the second provider edge via a selected logical path that has a highest path usage for which transmitting the received most recent data does not result in the selected logical path managing a higher percentage of network traffic than is dictated by the highest usage value for the selected logical path.

  • Patent number: 5803654
    Abstract: A control cable and conduit assembly mounting system includes a pair of integrally formed, arcuate, spaced-apart, flexible flanges which substantially encircle a hollow handlebar or frame member. Also included is a post contained between the flanges which extends through a hole formed in the wall of the tubular handlebar or frame member. The post provides axial and rotational position stability and resists displacing forces caused by movement of the control cable or other forces tending to move the control cable along or rotate the conduit around the handlebar or frame member. The flexible flanges maintain the control cable and conduit assembly in a position proximate to the handlebar or frame member. The elimination of the use of screws or fasteners allows for the cable center line to be parallel with the center line of the handlebar or frame member.
