Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, fig. 1 is a schematic diagram of an implementation environment of a video networking remote control system according to an embodiment of the present invention. As shown in fig. 1, the implementation environment includes: the system comprises a network management client, a video network server and a video network terminal. The network management server is connected with the video network server through the video network, and the video network terminal is connected with the video network server through the video network.
Referring to fig. 2, fig. 2 is a flowchart of a method for remotely controlling a video network 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 a video network remote control system, where a remote console supporting an operating environment of a first operating system 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 console of the webmaster client, generating a corresponding first operating system command.
In this embodiment, the video networking terminal that is remotely controlled may include, but is not limited to, a set top box (SetTopBox, STB). The set-top box is an embedded system, and is a system based on Linux kernel customization, namely a first operating system, the video networking terminal can run a first operating system command, namely a Linux command, and at the moment, the remote console which is preset in the network management client and supports the running environment of the first operating system is a remote console which supports the running environment of the system based on Linux kernel customization.
The network management client is a client program on a PC (personal computer), is provided with a graphical interface and is used for managing video networking equipment, including management of video networking terminals. 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 network terminal.
When the first operating system is a Linux kernel-based customized system, the remote console preset in the network management client may be a console similar to a Linux bash script or a Linux sh script operating environment, and a user may directly input remote control information, such as an input character "ls", on the console interface and then press a preset key, such as a enter key, at this time, the network management client may 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 the remote control console is realized by simulating the local control console of the video network terminal, the interface is friendly, and the operation of a user on the video network terminal is facilitated.
Illustratively, a user inputs a character "ls" in a Linux bash script console provided by a webmaster client, and presses an enter key, at this time, the webmaster client processes the character "ls" to generate a first operating system command, that is, an "ls" command of Linux.
The video network terminals which are remotely controlled are accessed into the video network, the video network terminals are subjected to network access authentication in the video network, the terminals can be displayed on a network management client interface in a list form, each video network terminal corresponds to a unique video network terminal identifier, each terminal corresponds to a console opening function, for example, each video network terminal corresponds to a console opening button, and a user can enter a remote console by clicking the button, so that the remote control information of the video network terminal is input.
In addition, it should be noted that the user can perform remote control on the video networking terminal only after successfully logging in the network management client, so that the security of remote control on the video networking terminal in the video networking is improved.
And step S22, packaging the first operating system command according to the video networking protocol to obtain a video networking signaling.
The video networking protocol is a protocol used in video networking, is different from a tcp/IP protocol, and does not need addressing 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 a video networking signaling, so as to facilitate transmission in a video networking environment. In particular, the first operating system command belongs to a part of the user data (payload), adding an view network header in the payload header, i.e. can be encapsulated as view network signaling.
In addition, in this embodiment, any suitable encryption means can be used for encrypting and transmitting the encapsulated video networking signaling, so as to further ensure the security of controlling the video networking terminal.
And step S23, the video network server sends the video network signaling to the video network terminal capable of executing the first operating system command for 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 can be sent to the video networking server, and then the video networking server forwards the video networking signaling to the corresponding video networking terminal, that is, the console button corresponding to which video networking terminal the user clicks is used to send the video networking signaling 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 may parse the video networking signaling to obtain a first operating system command, and then execute the first operating system command, for example, if the "ls" command is parsed, the "ls" command of Linux may be executed.
In the embodiment of the invention, when the network management client detects the remote control information input by a user at the remote console of the network management client, the network management client generates a 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 for remote control.
In addition, in consideration of the fact that a user needs to obtain the output content of the video network client in the remote control of the network management client to the video network terminal, in an embodiment, in order to facilitate the user to timely obtain the remote control result of the video network terminal, after the video network server sends the video network signaling to the video network terminal capable of executing the first operating system command, and the remote control is performed, the following steps may be specifically performed:
step S24, receiving an execution response from the video network terminal sent by the video network server, where the execution response is obtained by the video network terminal encapsulating the execution result according to the video network protocol.
Step S25, parsing the execution response, and obtaining an execution result obtained by the video network terminal executing the first operating system command.
In this embodiment, after the video network terminal executes the corresponding first operating system command, the video network terminal may output an execution result, and the video network terminal may obtain the execution result of executing the first operating system command. Illustratively, the first os command obtained by the video networking terminal after parsing the video networking signaling is an "ls-lR/bin" command, and then the video networking terminal may execute the "ls-lR/bin" command to obtain an execution result, that is, listing all directory and file details below the/bin directory. Then, the video networking terminal encapsulates the execution result according to the video networking protocol to obtain an execution response, and the process of encapsulating the execution result by using the video networking protocol refers to the process of encapsulating the first operating system command, which is not described herein again.
After the video network terminal obtains the execution response, the execution response can be sent to the video network server, and then the video network server forwards the execution response to the network management server, so that the network management client can analyze the execution response, obtain an execution result obtained by the video network terminal executing the first operating system command, and display the execution result on a remote console of the network management client, namely, the network management client can obtain the remote control result.
Still taking the case that the first os command is "ls-lR/bin" command, the execution result obtained by the webmaster client is all the directory and file details below the bin directory, that is, the console interface can display all the directory and file details below the bin directory.
In view of the limited size of the video network signaling, therefore, in order to compress the first operating system command and facilitate the transmission of the first operating system command in the video network, in an implementation, after step S21, the method for remotely controlling the video network terminal 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 coded remote control instruction according to a video networking protocol to obtain a video networking signaling.
In this embodiment, the preset encoding rule may be specified by the developers of the video networking terminal and the network management client in advance to have a protocol, and code development is performed according to the protocol. For example, the "ls" command is encoded as "0 xa 0", the "ps" command is encoded as "0 xa 1", and the "cd" command is encoded as "0 xa 2".
It should be noted that, the above is only an example of the preset encoding rule, and the actual encoding rule may not be encoded according to the above 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 instruction, and at this time, the network management client may encapsulate the encoded remote control instruction to obtain the video networking signaling.
In this embodiment, the first operating system command is encoded and then the data that can be compressed for transmission is sent, so as to ensure normal transmission of the video networking signaling.
In an implementation, the first operating system command may specifically be an inquiry command, and at this time, the method for remotely controlling a video network terminal according to this embodiment may specifically include the steps of:
step S261, when the first operating system command is an inquiry command, sending a first video networking signaling carrying an inquiry action and an inquiry object to the video networking terminal through the video networking server, so that the video networking terminal executes the inquiry action on the inquiry object according to the first video networking signaling, and receives an inquiry result returned by the video networking terminal.
In this embodiment, the query command may be used to obtain local information of the video network terminal from the video network terminal, including various file information and various configuration information, and therefore, the query command may specifically be a file query command and a configuration query command.
The file query command refers to that the first operating system command is used for querying a local file of the video networking terminal, and at this time, the query object refers to which file or which target path the file query action specifically targets. The video network 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 network protocol.
The query configuration command refers to that the first operating system command is used for querying the system configuration of the video network terminal, and at this time, the query object refers to which system configuration the query action specifically targets. The video network terminal executes the query action on the query object, can output the configuration query result, and returns the configuration query result to the network management client through the video network protocol.
In an implementation, the first operating system command may specifically be a configuration command, and at this time, the method for remotely controlling a video network terminal according to this embodiment may specifically include the steps of:
step S262, when the first operating system command is a configuration command, sending a second video networking signaling carrying a configuration action and configuration parameters to the video networking terminal through the video networking server, so that the video networking terminal configures according to the configuration action and the configuration parameters, and receives a configuration result returned by the video 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, the configuration command may include a firewall configuration command or a telnet remote service configuration command.
The firewall configuration command is used for configuring a firewall of the video networking terminal, and the configuration parameter is a parameter which is specifically required to be configured in a configuration action. After the terminal of the video network configures the firewall parameters of the firewall, the configuration result may be output, for example, the configuration result may be successful configuration and parameter information after configuration, and the configuration result is returned to the network management client through the video network protocol.
The telnet remote service configuration command means that the first operating system command is used for configuring telnet remote services of the video network terminal, and the configuration parameter means a parameter to be specifically configured for a configuration action, for example, the state of the telnet remote service is open, and the state of the port number 23 is open. After the video networking terminal configures the telnet remote service, the configuration result may be output, for example, the configuration result may be that the telnet remote service is successfully opened and the port 23 is opened, and the configuration result is returned to the network management client through the video networking protocol.
In this embodiment, the reason why the first operating system command may be the telnet remote service configuration command is as follows: considering that more operations can be implemented through telnet remote service than that initiated by a network management client, for example, a local file is edited by using an application vi built in a terminal system, or a client has a need to use telnet remote service, or an operator of the network management client needs sometime other people who cannot use the network management client to perform some operations through telnet, therefore, the remote service initiated by the network management client cannot completely replace telnet remote service, and in some cases, the network management client still needs to initiate a telnet remote service configuration instruction.

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 the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;
the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);
the reserved byte consists of 2 bytes;
the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;
the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
| DA | SA | ved Reser | label (R) | ad Paylo | CRC |
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
