Filed: 2018-12-10
Abstract: A method and apparatus for implementing communication between nodes, and an electronic device. The method is applied to a user node in a serial attached small computer system interface (SAS) network system. The method comprises: obtaining target data to be transmitted sent by a target program; constructing an Ethernet packet in which the target data is carried; encapsulating the Ethernet packet as an SAS protocol packet; and sending the SAS protocol packet to an SAS-HBA in the user node, so that the SAS-HBA sends, by means of a forwarding node, the SAS protocol packet to a destination user node serving as a data receiver; upon receiving the SAS protocol packet, the destination user node decapsulates the SAS protocol packet as the Ethernet packet, and decapsulates the Ethernet packet as the target data, wherein the SAS-HBA is a host bus adapter using an SAS protocol. This solution enables the SAS network system to be compatible with an Ethernet communication interface, thereby reducing the coupling between the application layer and the data transmission layer of the user node.
