Latest Patents

One of Mark's latest patents is titled "Dynamic rate control scheduler for ATM networks." This invention introduces a Dynamic Rate Control (DRC) scheduler that effectively manages the scheduling of cells for service in a generic ATM switch. The DRC ensures that each traffic stream associated with an internal switch queue is rate-shaped according to a minimum guaranteed rate, along with a dynamic component based on congestion information within the switch. This innovative approach not only achieves high utilization but also guarantees a minimum throughput for each stream while fairly distributing unused bandwidth. The DRC's flexibility allows for the distribution of unused bandwidth to be assigned in a manner that does not necessarily adhere to minimum throughput guarantees, unlike traditional weighted fair share schedulers. Additionally, the DRC can control internal congestion at bottleneck points within a multistage switch and can be extended beyond the local switch in a hop-by-hop manner.

Another significant patent by Mark is the "Time-based scheduler architecture and method for ATM networks." This invention presents a flexible and scalable architecture that implements dynamic rate control scheduling in an ATM switch. The scheduler shapes numerous streams according to rate values that are computed dynamically based on switch congestion information. To accommodate a wide range of bit rates, multiple timewheels with varying time granularities are employed. The streams are dynamically assigned to these timewheels based on computed rate values, and the architecture supports priority levels for arbitrating among streams that are simultaneously eligible to transmit.
