Title: **David S. Curry: Innovator in Network Traffic Management**
Introduction
David S. Curry, a notable inventor based in San Jose, California, is recognized for his significant contributions to networking technologies. With four patents attributed to his name, Curry has made advancements in the management and scheduling of network traffic, enhancing the quality of service (QoS) in data transmission.
Latest Patents
Among Curry's latest patents is a method for **differentiated services using weighted quality of service (QoS)**. This innovation addresses network traffic by queuing it into separate per-flow queues and scheduling it into a group queue. By implementing congestion management, traffic is marked with priority values, allowing efficient handling of both 'in contract' and 'out of contract' traffic based on predefined limits. Higher priority traffic is given preferred scheduling, while lower priority traffic is managed through a round-robin approach.
Another pivotal invention by Curry, titled **apparatus and methods for scheduling packets in a broadband data stream**, involves a comprehensive packet scheduling system. This system includes components such as a packet manager interface, a policer, and a congestion manager. The policer assigns priority to each packet, which the congestion manager uses to determine packet transmission based on current congestion levels. The scheduler works in line with configured rates for virtual connections, efficiently queuing packets and ensuring orderly transmission.
