Title: Innovations of Tong-Bi Pei in ATM Traffic Scheduling

Introduction

Tong-Bi Pei is a notable inventor based in Milpitas, California, recognized for his contributions to the field of asynchronous transfer mode (ATM) technology. He holds two patents that focus on enhancing the efficiency of ATM traffic scheduling. His work has significantly impacted how data is transmitted over networks, ensuring that various types of traffic can coexist without compromising performance.

Latest Patents

One of Tong-Bi Pei's latest patents is titled "Hierarchical schedules for different ATM traffic." This invention introduces an ATM scheduler that supports multiple transmission traffic types, including constant bit rate (CBR), variable bit rate (VBR), and available bit rate (ABR) for various virtual path connections (VPCs) on an ATM link. The scheduler maintains scheduling tables that define the hierarchy of traffic types and the scheduling for each type within each virtual path. It identifies a VPC assigned to transmit during each cell time and prioritizes high-priority traffic, ensuring efficient data transmission.

Another significant patent is "Non-zero minimum cell rate for available bit rate ATM service." This invention provides a method for scheduling ABR traffic over an ATM link, ensuring that circuits with ABR traffic receive a minimum cell rate that is greater than zero. The scheduler utilizes both static and dynamic scheduling information to optimize traffic flow, allowing for effective transmission opportunities for both high-priority and ABR circuits.
