Title: Gopalakrishnan Ramamurthy: Innovator in High-Speed Switching Technologies

Introduction

Gopalakrishnan Ramamurthy is a prominent inventor based in Cranbury, NJ (US), known for his significant contributions to high-speed switching technologies. With a total of 12 patents to his name, he has made remarkable advancements in the field of telecommunications and data processing.

Latest Patents

One of his latest patents is titled "RRGS-round-robin greedy scheduling for input/output terabit switches." This innovative protocol addresses the scheduling of packets in high-speed cell-based switches. The design assumes the use of a logical cross-bar fabric with input buffers, making it applicable to both optical and electronic switches with terabit capacity. The proposed round-robin greedy scheduling (RRGS) achieves optimal scheduling at terabit throughput by utilizing a pipeline technique, which avoids the need for internal speedup of the switching fabric to maintain high utilization.

Another notable patent is the "Optimal buffer management scheme with dynamic queue length thresholds for ATM switches." This buffer management scheme ensures efficient and fair usage of buffer memory by applying static and dynamic thresholds at different levels. The dynamic threshold mechanism maximizes overall memory utilization while ensuring fair sharing of memory among the output port queues.
