The USB Device on the computing node BMC is connected to the USB HUB and forms a connection with the RMC.
Introduction of TCP/IP over USB function:
the TCP/IP over USB technology uses a USB bus to transmit TCP/IP data messages.
RNDIS (Remote Network Driver Interface Specification) is a short for Remote Network Driver Interface Specification, is a USB Ethernet card model defined by Microsoft, and spans a transmission layer, a Network layer and a data link layer, defines a communication Interface Specification between a Network card or a Network card Driver and an upper layer protocol Driver, shields different bottom layer physical hardware, and enables the upper layer protocol Driver to communicate with the bottom layer Network card of any model. The NDIS creates a complete development environment for the network driver, only the NDIS function needs to be called, and the problems of a kernel of an operating system and interfaces with other drivers do not need to be considered, so that the network driver can be separated from complex communication with the operating system, and the network driver is greatly convenient to write. In addition, the NDIS packaging characteristic is utilized, so that the design of one layer of drive can be concentrated, the design complexity is reduced, and meanwhile, the driver stack is easy to expand. The RNDIS is actually a TCP/IP over USB based on the USB, namely TCP/IP is run on the USB device, and the USB device looks like a network card.

S2, configuring RMC IP and BMC IP of the server.
In the design, an intranet IP address adopts a fixed IP address, the RMC address is fixed to 192.168.1.1, the IP address of the node BMC is related to the slot position where the node BMC is located, the slot position 0 address is fixed to 192.168.1.100, the slot position 1 address is fixed to 192.168.1.101, and the like.
Hardware IO serial numbers are arranged in the slot positions of the server nodes, and after the server nodes are inserted, the node BMC can sense the current slot position addresses by reading the IO. And then, configuring the static IP address according to the slot number. After the network is connected, the fixed IP address 192.168.1.1/2 of the RMC is tried to be connected, the state information is reported, and the data is synchronized into the RMC.
ifconfig usb0 192.168.1.1up
ifconfig usb0 192.168.1.100up
S3, setting the mapping relation between the BMC port and the remote management server port in the RMC.
In the design, aiming at part of special application scenes and customer requirements, a port mapping function is added in the RMC, so that each node BMC address in an intranet can access a remote management server in a port mapping mode, and a user can also independently access the function of the node BMC.
For example, the outer network IP of RMC is 10.16.1.5, the Web port of node BMC0 is mapped to 8080, the Web port of node BMC1 is mapped to 8081, and so on.
In addition, when the firmware is updated, a client directly logs in the RMC to update the firmware of the node BMC, and after the RMC receives the firmware verification package and verifies OK, the RMC forwards the firmware to the node BMC with the matched model, and the BMC updates the firmware. Therefore, when the client uploads the firmware once, the RMC will finish upgrading all the matched nodes BMC in batch, and give a feedback result of which nodes are upgraded successfully.
And for each node BMC, IP is distributed according to the slot position, mapping work of fixed port numbers is correspondingly and sequentially carried out, and the RMC dynamically adds and ages a corresponding port mapping table according to the network state of the node BMC. The user only needs to know the management network IP of the RMC and the port number which is required to be accessed and is related to the RMC, and the user can directly access the node BMC. For example, the outer network IP of RMC is 10.16.1.5, the Web port of node BMC0 is mapped to 8080, the Web port of node BMC1 is mapped to 8081, and so on. Accessing the RMC: direct access 10.16.1.5, and direct access to BMC0 10.16.1.5: 8080.
Although the present invention has been described in detail by referring to the drawings in connection with the preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made on the embodiments of the present invention by those skilled in the art without departing from the spirit and scope of the present invention, and these modifications or substitutions are within the scope of the present invention/any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
