Latest Patents

One of Jiann-Hwa Liou's latest patents is titled "Method and switch controller for easing flow congestion in network." This invention presents a method for alleviating data transmission congestion in a switch device that features multiple ports. The switch device includes a shared buffer that can be divided into several buffering units. The method involves providing multiple output queues, each corresponding to a port, with reserved buffering units assigned in the shared buffer. When a packet is received from a source port, it is stored in an assigned buffering unit. The target port is determined based on the packet's header, linking the buffering unit to the corresponding output queue. This innovative approach allows for effective management of free buffering units based on reserved units and conditions of the source port.

Another significant patent is "Method and switch controller for relieving flow congestion in network." This invention describes a switch controller that utilizes a congestion control method to mitigate network congestion. The Ethernet switch controller can select an appropriate congestion control mode based on the connection port and the state of the connected device. If a flow control mode is activated, the switch controller issues a flow control frame and waits for a guard period. If the connected device continues to transmit packets after this period, the controller switches to a drop control mode, discarding received packets to prevent congestion. This invention ensures that congestion control can be maintained even when connected to devices lacking standard flow control capabilities.
