摘要： Disclosed are systems and devices for interfacing media access tuning circuitry that implements collision handling or traffic shaping with a reduced media independent interface (RMII). In some embodiments, an interface circuitry manages emulated signals generated by a media access tuning circuitry in response to detecting that the emulated signals would cause incorrect operation of an RMII. Also disclosed is a physical layer (PHY) device for a multidrop network. In some embodiments the PHY device implements physical layer collision techniques and operable to communicate with a media access control (MAC) device via an RMII, where the MAC is configured for carrier-sense multiple access (CSMA), CSMA with collision detection (CSMA/CD), or CSMA with collision avoidance (CSMA/CA). Also disclosed are processes for managing signaling at a PHY that implements physical layer collision avoidance (PLCA) or traffic shaping, as the case may be.

摘要： An example communication method includes that a first terminal device receives through a first path a first data packet from a second terminal device. The first terminal device receives through a second path a second data packet from a second terminal device, where the first path has a mapping relationship with the second path. The first terminal device transmits, based on the mapping relationship, the first data packet and the second data packet to a same aggregation protocol layer entity to perform data aggregation processing.

摘要： A transmission method includes: generating one or more transfer frames that each store one or more streams used for content transfer; and transmitting the one or more generated frames through broadcast, each of the one or more streams storing one or more second transfer units, each of the one or more second transfer units storing one or more first transfer units, and each of the one or more first transfer units storing one or more Internet Protocol (IP) packets. In at least one stream among the one or more streams, each of the first transfer units positioned at a head contains reference clock information indicating time used for reproduction of the content.

摘要： A first fabric abstraction layer couples to a data link layer and a physical layer of a network fabric device. The network fabric device is connected to other network elements within a network via at least one network connection, such as a fiber optic connection. A second fabric abstraction layer couples to the data link layer and an application of the network device. The second fabric abstraction layer provides an application programming interface (API) to the application. The API allows the application to generate configuration instructions for configuring the at least one network connection. Upon receiving the configuration instructions generated by the application, the second abstraction layer sends the configuration instructions to the first abstraction layer via the data link layer. The first abstraction layer then configures the at least one network connection to transmit data according to the configuration instructions.
