The invention provides a multi-experiment system and a control hosting method for the multi-experiment system, wherein the control hosting means that under the condition that the experiment system authorizes the hosting, a central monitoring hall provides remote control service for each experiment system. The control hosting function block diagram is shown in fig. 1 and comprises: the method comprises the steps of control hosting authorization facing each experimental system, remote control over the control hosting of each experimental system, remote control operation authority management of the control hosting, remote control operation log management of the control hosting and remote control operation audit management of the control hosting.
In the present invention, a network topology diagram of a control hosting method for a multi-experiment system and its central control is shown in fig. 2, wherein: the virtual private network is arranged in the control hosting unit and is linked with each experimental subsystem by adopting a multiplexing transmission network; the control hosting master-slave server controls a log and audit function, a verification and authorization management function and a remote instruction agent function in the hosting module; after the terminal passes authorization and identity verification, a virtual private network is established according to a specific experiment system controlled and managed by authorization, a remote instruction is issued through a remote instruction agent or a remote desktop, and log recording and post audit are received; in order to improve the security of controlling the hosting server, a firewall is established between networks linked with the hosting control terminal, and the specific network flow and the access port are controlled and monitored.
As shown in fig. 3, the specific implementation steps of the control hosting method for a multi-experiment system and its central control are as follows:
in step S1, the operator of each experimental system requests the control hosting authority from the experimental system in which the operator is located.
In this step, the user initiates an application request at the client that controls hosting, including the purpose, time range, hosting range, etc. of controlling hosting the application.
And step S2, each experimental system examines and approves the control hosting request and authorizes the control hosting request.
In this step, the local monitoring terminal performs auditing and approval according to the hosting application content and the service requirement, and provides user name, password and account number available time for authorization after approval.
In this step, controlling the hosting authorization includes: and presetting an account mode and an interactive request confirmation mode.
In this step, when authorization is performed in a preset account mode, an authorization account number capable of being remotely accessed is preset in an experimental system according to the requirement of controlling a hosting task, the account number is distributed to an operator of the experimental system in a central monitoring hall, remote login is performed by using the account number, and after the task of controlling the hosting is finished, the account number is logged out by each experimental system.
In this step, when authorization is performed in an interactive request confirmation mode, a remote control request is initiated on a hosting control terminal of a central monitoring hall, a response is waited, after the experiment system receives the request, an authorization confirmation instruction or a rejection instruction is sent to the application after confirmation, after the hosting control terminal receives the authorization instruction, a remote control interface is executed, and when the hosting control terminal receives the rejection instruction, the current operation is terminated.
Step S3, when the experimental system confirms the authorization, the control hosting private network is established.
In the step, in the aspect of network transmission, a multiplexing transmission network is adopted in the control hosting unit and is linked with the control hosting service of each experimental subsystem, one-to-one encryption networks are established among the experimental system monitoring computer, the control hosting master-slave server and the terminal, and network segments are shared independently, so that the control hosting networks of each experimental system are isolated. In the aspect of network interfaces, an application firewall is added to realize the isolation from the monitoring rear end of a terminal operated by a control personnel and an experiment subsystem.
In this step, the virtual private network includes: general purpose hardware-based virtual private networks and proprietary hardware-based virtual private networks. Wherein: the VPN based on general hardware installs VPN software service end (such as OpenVPN system) on general server hardware, installs VPN software client end on relative access node, establishes virtual network by using authorization key, account number and other information, obtains special network segment IP, can directly communicate with other nodes on the network segment, the communication data is transmitted on physical network through encryption. The special hardware-based virtual private network configures parameters of a server side on VPN special hardware equipment (such as a Huacheng VPN gateway and a Juniper VPN gateway), a related access point installs a VPN communication protocol meeting the requirements of the server side, and data can be transmitted on an encryption network after access.
And step S4, the managed control terminal starts the remote control software.
And step S5, the operator issues an instruction through the remote control software.
In this step, the operator provides the service of remote issuing of the control command through the remote command agent function and the remote desktop function. Wherein: the remote instruction agent is executed by providing an agent interface at the hosting control terminal and sending the specific instruction to a remote authorized corresponding experiment system monitoring computer.

In this step, when the experimental system monitoring software does not provide the SDK or API, or only provides the native control interface, the remote instruction agent software may be customized in a simulation operation manner. The information such as parameters, buttons and the like which need to be managed and controlled is input and obtained through a proxy interface which controls the operation of a managed terminal, and then the custom software inputs the obtained data to an experimental system control software interface in a simulation operation mode; in this process, the customization software records the relevant operations in detail.

Currently mainstream operating systems provide RDP protocols, VNC protocols, and the like. The client supporting the protocol is utilized to realize the aim of local remote operation by logging in the server providing the protocol.
In this step, when the control software limits the remote desktop operation, an IP-KVM method may be used to provide the remote operation service; the IP-KVM remote operation maps the keyboard, the image and the mouse of the remote computer to the local through an IP network, and realizes the operation of the remote computer through out-of-band control.
And step S6, the monitoring equipment receives the remote control instruction to perform corresponding operation.
Step S7, operation log recording is performed.
In the step, the log management and audit function records the operation process from top to bottom in detail according to the operation of the experimental system monitoring software, such as input data information, clicked buttons, click time, click sequence and the like; meanwhile, other information affected by the above operation, such as system critical event information, control program running state information, etc., is collected.
In this step, the log management includes: a control managed log facing a remote desktop and a control managed log facing a remote instruction agent.
In the step, a remote desktop protocol is utilized to record the complete hosting control operation passing through the remote desktop; and simultaneously recording relevant information of the computer under the control of the hosting in the relevant time period, such as active application programs, system load, network links and load, disk access load, operating system events and the like.
