Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
Referring to fig. 1, fig. 1 is a schematic diagram of an implementation environment of an internet-of-view remote control system according to an embodiment of the invention. As shown in fig. 1, the implementation environment includes: network management client, visual network server and visual network terminal. The network management server is connected with the video networking server through the video networking, and the video networking terminal is connected with the video networking server through the video networking.
Referring to fig. 2, fig. 2 is a flowchart of a method for remotely controlling an internet-of-view terminal according to an embodiment of the present invention, and as shown in fig. 2, the method may be applied to a network management client in an internet-of-view remote control system, where a remote console supporting a first operating system operating environment is preset in the network management client, and the method may specifically include the following steps:
Step S21, when detecting the remote control information input by the user at the remote control console of the network management client, generating a corresponding first operating system command.
In this embodiment, the remotely controlled video networking terminal may include, but is not limited to, a Set Top Box (STB). The set top box is an embedded system, is a system customized based on a Linux kernel, namely a first operating system, and the video networking terminal can run a first operating system command, namely a Linux command, and at the moment, a remote control console which is preset in the network management client and supports the operating environment of the first operating system is a remote control console which supports the operating environment of the system customized based on the Linux kernel.
The network management client is a client program on a PC and is provided with a graphical interface for managing the video networking equipment, including the management of the video networking terminal. The network management client is preset with a remote control console supporting the running environment of the first operating system, and is used for receiving control information input by a user and displaying output content returned by the video networking terminal.
When the first operating system is a system customized based on a Linux kernel, the remote control console preset in the network management client side can be a console similar to a Linux bash script or a Linux sh script running environment, a user can directly input remote control information, such as a character 'ls', on a console interface, then press a preset key, such as a carriage return key, at this time, the network management client side can detect the remote control information input by the user and process the remote control information to generate a first operating system command. In the embodiment, the function of a remote control console is realized by simulating the local control console of the video networking terminal, the interface is friendly, and the user can conveniently operate the video networking terminal.
For example, the user inputs a character "ls" on the Linux flash script console provided by the network management client, and presses the enter key, and at this time, the network management client processes the character "ls" to generate a first operating system command, i.e., a Linux "ls" command.
The remote controlled video networking terminals are video networking terminals which are accessed into the video networking and are subjected to network access authentication in the video networking, the terminals can be displayed on a network management client interface in a list form, each video networking terminal corresponds to only one video networking terminal identifier, each terminal corresponds to an opening console function, for example, each video networking terminal corresponds to an opening console button, and a user can enter a remote console by clicking the button, so that remote control information of the video networking terminal is input.
In addition, it should be noted that the user can remotely control the video networking terminal after successfully logging in the network management client, so that the security of the remote control of the video networking terminal in the video networking is improved.
And S22, packaging the first operating system command according to a video networking protocol to obtain video networking signaling.
The internet of view protocol is a protocol used in the internet of view, and is different from tcp/IP protocol, and does not need to address according to an IP address.
In this embodiment, after generating the corresponding first operating system command, the network management client may encapsulate the first operating system command according to the video networking protocol, so as to obtain the video networking signaling, so as to transmit the video networking signaling in the video networking environment. Specifically, the first operating system command is part of user data (load), and the video networking header is added to the load header, i.e. the video networking signaling can be encapsulated.
In addition, in the embodiment, any proper encryption means can be adopted to encrypt and transmit the packaged video networking signaling, so that the security of the control of the video networking terminal is further ensured.
And step S23, the video networking server sends the video networking signaling to a video networking terminal capable of executing a first operating system command to perform remote control.
In this embodiment, after the network management client encapsulates the first operating system command to obtain the video networking signaling, the video networking signaling may be sent to the video networking server, and then forwarded to the corresponding video networking terminal by the video networking server, that is, which of the console buttons corresponding to the video networking terminals is clicked by the user, so that the video networking signaling is sent to the corresponding video networking terminal.
After the video networking terminal receives the video networking signaling forwarded by the video networking server, the video networking terminal program can analyze the video networking signaling to obtain a first operating system command, and further execute the first operating system command, for example, if the "ls" command is analyzed, the "ls" command of Linux can be executed.
In the embodiment of the invention, when the network management client detects the remote control information input by the user at the remote control console of the network management client, the network management client generates the corresponding first operating system command, encapsulates the first operating system command according to the video networking protocol to obtain the video networking signaling, and then sends the video networking signaling to the video networking terminal capable of executing the first operating system command through the video networking server to perform remote control.
In addition, considering that the output content of the video networking client needs to be obtained by the user in the remote control of the video networking terminal at the network management client, in one embodiment, in order to facilitate the user to timely obtain the remote control result of the video networking terminal, after the video networking signaling is sent to the video networking terminal capable of executing the first operating system command by the video networking server to perform the remote control, the following steps may be specifically further performed:
And step S24, receiving an execution response from the video networking terminal, wherein the execution response is obtained by packaging an execution result by the video networking terminal according to the video networking protocol, and the execution response is sent by the video networking server.
And S25, analyzing the execution response to obtain an execution result obtained by the video networking terminal executing the first operating system command.
In this embodiment, after executing the corresponding first operating system command, the video networking terminal outputs an execution result, and the video networking terminal may obtain the execution result of executing the first operating system command. For example, the first operating system command obtained after the view networking terminal analyzes the view networking signaling is a "ls-lR/bin" command, and then the view networking terminal may execute the "ls-lR/bin" command to obtain an execution result, i.e. list all directories and file details below the/bin directory. And then, the video networking terminal encapsulates the execution result according to the video networking protocol to obtain an execution response, and the encapsulation process of the execution result by using the video networking protocol refers to the encapsulation process of the first operating system command, which is not described herein.
After the execution response is obtained by the video networking terminal, the execution response can be sent to the video networking server, and then forwarded to the network management server by the video networking server, the network management client can analyze the execution response to obtain an execution result obtained by the video networking terminal executing the first operating system command, and the execution result is displayed on a remote control console of the network management client, namely the network management client can obtain a remote control result.
Taking the first os command as an example, the execution result obtained by the network management client is all directories and file details below the bin directory, that is, the console interface may display all directories and file details below the bin directory.
In view of the limited size of the signaling of the internet of view, in order to compress the first operating system command, the transmission of the first operating system command in the internet of view is facilitated, and in one implementation, after step S21, the method for remotely controlling the terminal of the internet of view according to the embodiment of the present application may further include the following steps:
step S211, encoding the first operating system command according to an encoding rule preset by the remote control command, to obtain an encoded remote control command.
Accordingly, the step S22 may specifically include:
and step S221, packaging the encoded remote control instruction according to a video networking protocol to obtain video networking signaling.
In this embodiment, the preset encoding rule may be specified by a developer of the video networking terminal and the network management client in advance to obtain a protocol, and code development is performed according to the protocol. Illustratively, the "ls" command is encoded with "0xa0", the "ps" command is encoded with "0xa1", and the "cd" command is encoded with "0xa2".
It should be noted that the foregoing is merely an example of a preset encoding rule, and an actual encoding rule may not encode according to the foregoing rule.
Therefore, in this embodiment, after generating the corresponding first operating system command, the network management client may encode the first operating system command to obtain the encoded remote control command, and at this time, the network management client may encapsulate the encoded remote control command to obtain the video networking signaling, and likewise, the encapsulation process of the encoded remote control command is not described herein again.
In this embodiment, the data capable of being transmitted in a compressed manner is sent after the first operating system command is encoded, so that normal transmission of the video networking signaling is ensured, and on the other hand, the security of the transmission of the first operating system command can be ensured due to encoding the first operating system command, and the security of the video networking terminal can be ensured even if the first operating system command is obtained illegally.
In one embodiment, the first operating system command may be a query command, and in this case, the method for remotely controlling the video networking terminal of the embodiment may specifically include the steps of:
step S261, when the first operating system command is a query command, sending, by the view networking server, a first view networking signaling carrying a query action and a query object to the view networking terminal, so that the view networking terminal executes the query action on the query object according to the first view networking signaling, and receives a query result returned by the view networking terminal.
In this embodiment, the query command may be used to obtain local information of the internet-of-view terminal from the internet-of-view terminal, including various file information and various configuration information, and thus the query command may be specifically a query file command and a query configuration command.
The file inquiry command refers to that the first operating system command is used for inquiring a local file of the video networking terminal, and the inquiry object refers to which file or which target path is specifically aimed at by the file inquiry action. And the video networking terminal executes the query action on the query object, can output a file query result, and returns the file query result to the network management client through a video networking protocol.
The query configuration command refers to that the first operating system command is used for querying the system configuration of the video networking terminal, and the query object refers to which system configuration the query action specifically aims at. The video networking terminal executes the query action on the query object, can output configuration query results, and returns the configuration query results to the network management client through the video networking protocol.
In one embodiment, the first operating system command may be a configuration command, and in this case, the method for remotely controlling the video networking terminal of the embodiment may specifically include the steps of:
Step S262, when the first operating system command is a configuration command, sending, by the view networking server, a second view networking signaling carrying a configuration action and a configuration parameter to the view networking terminal, so that the view networking terminal configures according to the configuration action and the configuration parameter, and receiving a configuration result returned by the view networking terminal.
In this embodiment, the configuration command may be used to configure or modify a local system parameter of the video networking terminal, for example, may include a configuration firewall command or a configuration telnet remote service command.
The firewall configuration command is used for configuring the firewall of the video networking terminal, and the configuration parameters are parameters which are specifically required to be configured for the configuration action. After the firewall parameters of the firewall are configured by the video networking terminal, a configuration result can be output, for example, the configuration result can be parameter information after successful configuration and after configuration, and the configuration result is returned to the network management client through the video networking protocol.
The telnet remote service configuration command refers to that the first operating system command is used for configuring telnet remote services of the video networking terminal, and the configuration parameters are parameters which specifically need to be configured in a configuration action, for example, a telnet remote service state is opened, and a 23 # port state is opened. After the telnet remote service is configured by the video networking terminal, a configuration result can be output, for example, the configuration result can be that the telnet remote service is successfully opened and the number 23 port is opened, and the configuration result is returned to the network management client through the video networking protocol.
In this embodiment, the first operating system command may be a configuration telnet remote service instruction because: considering that the operations that can be achieved through telnet remote services are more than those that can be achieved through telnet remote services, for example, applications vi built in a terminal system are used for editing local files and the like, or clients have the need of using telnet remote services, or operators of the telnet clients temporarily need other personnel who cannot use the telnet clients to perform certain operations through telnet, therefore, the telnet remote services initiated by the telnet clients cannot be completely replaced, and in some cases, the telnet remote service configuration instructions still need to be initiated by the telnet clients.

Step S372, when the first operating system command is a configuration command, receives a second video networking signaling carrying a configuration action and a configuration parameter from the network management client sent by the video networking server, configures according to the configuration action and the configuration parameter, and returns a configuration result to the network management client.
Likewise, the specific content of this embodiment may be referred to the content of steps S261-S262, and will not be described here again.

As shown in the following table, the data packet of the access network mainly includes the following parts:
DA SA ved Reser ad Paylo CRC
wherein:
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), 256 possibilities are at most provided, the second byte to the sixth byte are metropolitan area network addresses, and the seventh and eighth bytes are access network addresses;
