Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to, but are not limited to the field of communication, and for example, relate to, but are not limited to a method and an apparatus for smart device management, a network device, and a computer-readable storage medium.BACKGROUND

[0002] Management Component Transport Protocol (MCTP) is a "data link layer" protocol based on a physical layer, which is independent of the communication between smart devices in computers of various media, which is convenient for platform management developers to quickly and economically develop and deploy platform management subsystems accessible by a Common Information Model (CIM). MCTP defines a transport layer protocol independent of physical media, and the link layer is defined in a series of MCTP binding protocols. The supported physical media types include: Peripheral Component Interconnect Express (PCIe), System Management Bus (SMBus), Universal Serial Bus (USB), Block Transfer (BT), Keyboard Controller Style (KCS), and the like.

[0003] The media types supported by most smart devices with computer systems supporting MCTP out-of-band management are PCIe and SMBus. A Management Component Transport Protocol Over Peripheral Component Interconnect Express Vendor Defined Message (MCTP Over PCIe VDM) transport binding specification defines a communication protocol between PCIe link based smart devices on the basis of a PCIe transport layer protocol. A Management Component Transfer Protocol Over System Management Bus (MCTP Over SMBus) transport binding specification defines a communication protocol between Inter-Integrated Circuit (I2C) link based smart devices on the basis of a (System Management Bus (SMBus) protocol, or the like. MCTP basic specifications define a communication mechanism between smart devices supporting different physical layer links.

[0004] A computer system equipped with a Baseboard Management Controller (BMC) communicates with a managed device via a physical channel such as out-of-band PCIe and SMBus by the BMC, and is responsible for hardware monitoring of the computer system.

[0005] A plurality of MCTP binding protocols defined by a Distributed Management Task Force (DMTF) and the MCTP basic specification together ensure that out-of-band communication can be implemented by smart devices of different manufacturers.

[0006] Generally, devices that support MCTP are all smart devices with processing units and firmware thereof. When out-of-band functions provided by the smart devices exceed the defined functions, such as the smart devices with switching functions providing switching configuration functions and debugging of smart devices, because there is no standard protocol definition, each smart device implements these functions according to manufacturer's implementation, and the BMC can't directly provide support, and when the smart devices are upgraded, the BMC also needs to be upgraded to support new functions. Similarly, external management software connected to the BMC can't manage the smart devices, or the smart devices can't be managed after adding new functions.

[0007] US20160378509A1 relates to a method including during boot of an information handling system, obtaining from a management controller integral to the information handling system information regarding resource requirements for one or more peripheral devices communicatively coupled to the one or more processor sockets integral to the information handling system and the management controller. The method may also include determining whether a default allocation of resources for the one or more peripheral devices among the one or more processor sockets by a basic input / output system integral to the information handling system satisfies the resource requirements. The method may further include, in response to determining the default allocation does not satisfy the resource requirements, rebalancing resources among the one or more processor sockets to satisfy the resource requirements prior to enumeration of the one or more peripheral devices.

[0008] US20180293197A1 relates to a method and information handling system including a first universal serial bus (USB) type C port for transceiving SMBus data multiplexed over unused USB-2 pins from a host information handling system, a first multiplexer for demultiplexing the SMBus as a designated data bus to a second multiplexer to create a designated bus for management controller transport protocol data, the second multiplexer re-multiplexing the SMBus designated bus to a second USB type C port for connection with an out-of-band management hardware system network interface card of a device connected to the second USB type C port for communication of management controller transport protocol data with the information handling system host and bypassing a docking station high capacity connector multiplex controller, and an embedded controller for activating the first multiplexer and the second multiplexer upon detecting the connection with the out-of-band management hardware system network interface card via the second USB type C port and establishing the designated data bus for management controller transport protocol data bypass connection.

[0009] US20130332605A1 relates to a network interface device (NID) or management access point of a system, configured to: receive requests to register one or more additional capabilities provided by a second intelligent device integrated into the system; in response to the request, register the additional capabilities within a capabilities listing; advertise the additional capabilities as being an available within the system; and respond to a request from an external requestor for access to one of the additional capabilities by forwarding the management protocol and payload to the second intelligent device to enable the second intelligent device to perform all substantive processing required for the request. The NID establishes and maintains a network session between the second intelligent device and any external requestor requesting access to the additional capabilities. In response to receiving a response from the second intelligent device, the NID packages the response and forwards the response to the external requestor.

[0010] EP3255527A1 relates to technologies for remote keyboard-video-mouse sessions including failover mechanisms. In some embodiments, a system can establish a first remote keyboard-video-mouse session between a console application on the system and a first server application executed by a controller on a server. The first remote keyboard-video-mouse session can be established via a first network connection between the system and the controller. Next, the system can detect an error associated with the first remote keyboard-video-mouse session. In response to the error, the system can establish a second remote keyboard-video-mouse session between the console application and a second server application executed by an operating or a basic input / output program on the server. The second remote keyboard-video-mouse session can be established via a second network connection between the system and the second server application.SUMMARY
