    摘要: Embodiments of the present invention provide a memory access method, a switch, and a multiprocessor system. The memory access method includes: receiving, by the switch, a data packet; matching a flow table on the data packet, where the flow table includes at least one flow entry, where the flow entry includes a matching field and an action field, and the at least one flow entry includes a first flow entry, where a matching field of the first flow entry is used to match source node information, destination node information, and a protocol type in the data packet, and an action field of the first flow entry is used to indicate an operation command for a storage device embedded in the switch; and when the data packet successfully matches the first flow entry, performing an operation on the storage device according to the operation command in the action field of the successfully matched first flow entry. In the present invention, a processor in a multiprocessor system accesses a storage device embedded in a switch, so as to reduce and even eliminate a possibility that the processor accesses a remote memory, and reduce a memory access delay.

    摘要: Embodiments of the present invention disclose a method for mapping a packet service onto an optical transport network, including: receiving a packet service message from an access side, and identifying the packet service message by using a first board number of a first line board in which a first egress is located and a first port number of the first egress; sending the packet service message to the first line board corresponding to the first board number; and encapsulating the packet service message that is sent to the first line board, mapping an encapsulated packet service message onto a first optical channel data unit ODU corresponding to the first port number, and sending the first ODU by using the first egress. According to the foregoing technical solutions, cross-connect scheduling of any bandwidth in any direction is implemented based on a packet service, and packet services on different tributary boards share different ODU timeslot or a same ODU timeslot on a same line board.

    摘要: The invention relates to a method for implementing an industry internet field broadband bus, and in the method according to the invention, a bus controller and respective bus terminals transmit data in their respective time slices to thereby ensure timely and temporally determinist data transmission. Thus the embodiments of the invention implement a high-performance, highly reliable, and highly real-time method for implementing an industry internet field broadband bus. Moreover a transmission medium of the two-wire data transmission network can be a twisted pair or a shielded twisted pair so that the method according to the embodiment of the invention can be applicable to a traditional industry control facility using a bus, and thus can be highly universally applicable.
