  • Patent number: 12219041
    Abstract: This application describes a data transmission method, a network node, and a storage medium for communications technologies. In this application, an underlay segment identifier corresponding to an underlay path is designed, and the underlay segment identifier is advertised, so that a node on a segment routing network can sense the underlay path by using the underlay segment identifier. In this way, when a data packet is transmitted, the data packet can be sent based on an underlay segment identifier carried in the data packet and through an underlay path corresponding to the underlay segment identifier. Therefore, an underlay path through which a data packet is to be transmitted may be specified based on a service requirement, so that different data packets can be transmitted through different underlay paths, thereby improving flexibility and facilitating traffic planning.

  • Publication number: 20240304529
    Abstract: Implementations of high-power semiconductor device modules are described, including automotive power transistor assemblies for use in power amplifier circuits such as a cascode circuit. In some implementations, power amplifier circuit components are provided on separate semiconductor die attached to discrete dual die attach pads. A separation between the die attach pads, as well as a through-hole, provide sufficient isolation between the die to permit operation of the circuit at high voltages without relying on a thick multi-layer direct bond copper (DBC) isolation structure. In some implementations, higher voltage operation can be supported by a thin multi-layer, resin coated copper DAP in which the top layer is split.
