Latest Patents
One of Cheng's latest patents is a self-adaptive scheduling method and network element. This invention relates to a method and network element for scheduling data transmission in a packet data network, such as a differentiated services network. The method classifies data traffic of a predetermined traffic class based on a specific traffic profile, estimating the in-profile rate of the data traffic. By adjusting the weight that determines the transmit order of queued data packets, the invention improves fairness between classified flows in the packet data network. This approach allows for enhanced fairness between different traffic profiles effectively.
Another significant patent by Cheng involves TCP-friendly markers and methods using token buckets. This system marks packets with a precedence value based on a probability function. It enables interleaving of differently marked packets when a certain number of packets have been successively marked with a low or medium precedence value. This innovation aims to optimize network traffic management while maintaining TCP-friendliness.
