  • Patent number: 11736216
    Abstract: A network element includes at least two Time Division Multiplexing (TDM) modules each including a TDM client interface, TDM processing circuitry, and circuit emulation circuitry; and a packet switch fabric connected to the at least two TDM modules in a Link Aggregation Group (LAG) for a protected TDM service, and configured to output a packet interface, wherein the protected TDM service is provided as a single packetized TDM stream via the packet interface from the packet switch fabric.
    Type: Grant

  • Patent number: 7430173
    Abstract: A data traffic policer includes a classifier for separating a packet stream in accordance with class, a first bucket for a first traffic class representing a first transmission rate and a first burst capacity and a plurality of second buckets for a plurality of second traffic classes representing a corresponding second transmission rates and a second burst capacities, the plurality of second buckets being nested within the first bucket thereby being subordinate to the rate and capacity of the first bucket, with the rate of the second bucket being disabled when a fill condition exists in the first bucket. The second bucket for a second traffic class may include a plurality of buckets for a corresponding plurality of traffic classes, with each bucket of the plurality of buckets having a corresponding capacity and rate. The rate defined as a corresponding weight.

  • Patent number: 6501762
    Abstract: Scheduler methods and apparatus utilize a weight limited FIFO (WLF) method to provide weighted per-connection queuing while maximizing preservation of cell arrival order, thus minimizing additional cell delay variation (CDV) added during scheduling. The invention minimizes additional CDV of a connection until the connection exceeds its fair share of resource utilization.
