  • Publication number: 20250279960
    Abstract: A distributed system includes a first routing node device, a second routing node device, and a global routing service node device, connected to a backbone network. The first routing node device is distributed in an access network and configured to access one or more Internet service provider (ISP) networks, and includes a universal service component and a first universal switching component. The second routing node device is distributed in a data center network and configured to provide data connection between network modules in the data center network, and includes a second universal switching component. The global routing service node device is arranged outside the access network and the data center network. A mapping relationship between peering connections and scheduling labels is maintained in the distributed system and transmitted between node devices. The node devices perform transmission scheduling of service packet in the cloud network based on the mapping relationship.

  • Patent number: 12083647
    Abstract: Disclosed is a magnetorheological-elastomer (MRE) polishing pad suitable for chemical mechanical polishing (CMP) of a semiconductor wafer, which simultaneously realizes high-efficiency magnetic control polishing and high-efficiency Fenton reaction, forms an organosilicon-polyurethane matrix through an organosilicon-modified polyurethane prepolymer, and combines the characteristics of high flexibility and excellent comprehensive mechanical properties of organosilicon. CIP@Fe3O4 composite magnetic particles in the polishing pad can make the MRE polishing pad exhibit a high magnetorheological effect, and the produced ·OH can oxidize a surface of the semiconductor wafer to generate an oxide layer, reducing the material removal difficulty of abrasive materials and the polishing pad under the mechanical action.
