  • Publication number: 20210258282
    Abstract: A method for propagating a movement event message of a network entity, including: step 1) a network device maintaining a historical forwarded information list, wherein a network device capable of receiving a movement event message from an external system or device maintains an uplink port information table; step 2) after receiving the message, the network device performs matching using the table to obtain a forwarding port and forwarding information of the message, and constructs a movement event forwarding message using the information and forwards through the forwarding port; and step 3) after a device receives the message, searching for a matching forwarding port and forwarding information of the message in the information list, modifying the message using the forwarding information, and forwarding the modified message through the forwarding port. The method is able to propagate a movement event message to a network device responsible for related data transmission and forwarding.

  • Publication number: 20210257254
    Abstract: A method includes forming an ILD to cover a gate stack of a transistor. The ILD and the gate stack are parts of a wafer. The ILD is etched to form a contact opening, and a source/drain region of the transistor or a gate electrode in the gate stack is exposed through the contact opening. A conductive capping layer is formed to extend into the contact opening. A metal-containing material is plated on the conductive capping layer in a plating solution using electrochemical plating. The metal-containing material has a portion filling the contact opening. The plating solution has a sulfur content lower than about 100 ppm. A planarization is performed on the wafer to remove excess portions of the metal-containing material.

  • Publication number: 20210257916
    Abstract: When a constant on-time flyback converter is in the switch-on stage, the gate voltage of the switch and the input voltage of the flyback converter adopt the primary side of the transformer to control. The gate voltage is controlled by the second control signal generated by the controller. The flyback converter is then turn off to enter the switch off stage. When the flyback converter is in the switch off stage, the secondary side controller on the secondary side of the transformer, based on the output voltage and output current of the secondary side, sends a first control signal to the primary side controller to control the main switch to turn on. Thus, the flyback converter enters the switch-on stage. Therefore, the calculation complexity is reduced, and there is no need to set a blanking time, such that the flyback converter can be used in high switching frequency applications.
