  • Resilient routing systems and methods
    Patent number: 7817539
    Abstract: A network comprises nodes and links. In addition to a default topology there are backup configurations. Each node is inhibited from transferring data between nodes in at least one backup configuration. When a node detects a fault in the reception of data transmitted to a neighbouring node, it switches to a backup configuration in which the neighbouring node is inhibited. In one arrangement a backup configuration has at least one link which is restricted by having a high weighting so that it transmits data to a node only if that node is the final destination node for that data. Additionally, if the neighbouring node is the final destination, and routing of data is still unsuccessful in the backup configuration, the detecting node selects and switches to an alternate backup configuration in which the detecting node is inhibited.

  • System for rate-control of aggregate-rate communication services
    Patent number: 7817550
    Abstract: A method of rate-control for a group of ports in a communication network. Ramping is performed for allowed-rate of each of the group of ports, if sum of the ingress-rates of the group of ports is less than a given rate threshold; and adjusting is performed for allowed-rate of each of the group of ports, if sum of the ingress-rates of the group of ports is greater than or equal to the given rate threshold, such that the sum of allowed-rates of the group of ports is equal to the given rate threshold.
