摘要： Methods and apparatus for end-to-end data plane offloading for distributed storage using protocol hardware and Protocol Independent Switch Architecture (PISA) devices. Hardware-based data plane forwarding is implemented in compute and storage switches that comprise smart server switches running software executing in a kernel and user space. The compute switch is coupled to one or more compute servers/nodes and the storage server is coupled to one or more storage servers or storage arrays. The hardware-based data plane forwarding facilitates an end-to-end data plane between the computer server(s) and storage server(s)/array(s) that is offloaded to hardware. In one example the software comprises Ceph components used to implement control plane operations in connection with hardware offloaded data plane operations, and storage traffic employs the NVMe-oF protocol and the kernels include NVMe-oF modules. In one aspect the hardware-based data plane forwarding is implemented using programmable P4switch chips. In one aspect the storage and server switches are Top of Rack (ToR) switches.

摘要： A method for implementing a virtual network interface, which is applicable for the embedded device without a physical network interface equipped, including that: the embedded device encapsulates the to-be-transmitted IP data packet as the data frame which is able to be identified by the universal interface on the device and carries a virtual network port identifier, transmits the data frame through the universal interface; after the embedded device receives the data frame from the universal interface, the embedded device delivers the IP data packet parsed from the received data frames to the application layer when determining that the received data frame carries a virtual network port identifier. An embedded device for implementing a virtual network interface is also provided, the device includes a universal interface, a determining module, an encapsulating/decapsulating module, and a sending/receiving module.
