Title: The Innovations of Pu Cheng
Introduction
Pu Cheng is a notable inventor based in Nanjing, China. He has made significant contributions to the field of technology, particularly in network switching methods. With a total of 4 patents to his name, his work has had a considerable impact on the industry.
Latest Patents
One of Pu Cheng's latest patents is a path switching method and related apparatus. This application provides a path switching method that utilizes an ECMP table, which includes a first ECMP index of a first path group and a second ECMP index of a second path group. When all paths in the first path group fail, the path group identifier corresponding to the first ECMP index is changed from valid to invalid, indicating that all paths in that group are unavailable. This allows for efficient switching between an active path and a standby path, significantly reducing path switching delays.
Another significant patent is a loop failure handling method and switch. In this invention, a switch receives a first packet that includes a source media access control MAC address. The switch then obtains a first flapping count corresponding to the source MAC address to determine if a loop failure occurs in the network. If a loop failure is detected, the switch identifies a primary port that must be suppressed and enables a flooding suppression function on that port to prevent the forwarding of flooding packets.
