  • Patent number: 10715600
    Abstract: A hub is connected to first and second networks where first-type and second-type frames are transmitted following first and second communication protocols. The hub sequentially receives each of the first-type and second-type frames, and stores data in first and second reception buffers. If the destination of data stored in the first and second reception buffers is the first network, the hub stores the data in a first transmission buffer. If the destination is the second network, the hub stores the data in a second transmission buffer. If the first transmission buffer is a priority transmission buffer, the hub transmits first yet-to-be-transmitted data in the first transmission buffer with priority. If the second transmission buffer is the priority transmission buffer, the hub transmits second yet-to-be-transmitted data in the second transmission buffer with priority.
