2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

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 data packets, and is 64 bytes if the data packet is a variety of protocol packets, and is 32+1024 or 1056 bytes if the data packet is a unicast data 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 application: 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

Reserved

label (R)

Payload

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.

Based on the characteristics of the video network, the remote control scheme based on the video network protocol is provided, so that a single server can be remotely operated by multiple persons at the same time, and the equipment utilization rate and the working efficiency are improved.

Referring to fig. 5, a flowchart illustrating steps of a remote control method according to an embodiment of the present application is shown. Referring to fig. 8, a flowchart of a remote control method according to an embodiment of the present application is shown. The remote control method can be applied to the video network, and the video network can comprise a controlled terminal and a plurality of main control terminals.

The video network is a real-time large-bandwidth transmission network based on Ethernet hardware, and is a special network for transmitting high-definition video and special protocols at high speed.

The controlled terminal and the master terminal may include, but are not limited to, a mobile phone, a computer, a Set Top Box (STB), and the like. A set-top box, also called a set-top box or set-top box, is a device that connects a television set to an external signal source and can convert compressed digital signals into television content for display on the television set. Generally, the set-top box may be connected to a camera and a microphone for collecting multimedia data such as video data and audio data, and may also be connected to a television for playing multimedia data such as video data and audio data.

The remote control method provided by the embodiment may include the following steps:

step 501, receiving authentication information sent by each master control terminal through the video network.

Specifically, authentication information such as a user name and a password may be input on a remote control software interface of the master control terminal, the authentication information is sent to the controlled terminal through the video network, and the controlled terminal receives and verifies the authentication information.

Step 502, when the authentication is passed, recording the session identifier between each master control terminal and the controlled terminal.

Specifically, when the authentication information sent by a master terminal (user) is authenticated by a controlled terminal which opens a remote desktop (or remote control software), a session between the controlled terminal and the master terminal is started. Each session is identified using a unique session identification (session ID).

For example, when a user logs in to a machine with a remote desktop opened by a user name and password, i.e., authentication is passed, the session identification between the user and the machine may be recorded.

A machine may log on to multiple users simultaneously (including remote user login), with a session between a user and the machine (corresponding to a session ID, the remote user is referred to as a remote session).

Step 503, create the interworking station and desktop corresponding to the session identification.

Wherein a workstation (window station) is a secure object comprising a clipboard, a series of global atoms, and a set of desktop objects. Common workstations (non-interactive workstations) are all non-interactive to the user, meaning that they are not visible to the user nor can they accept user input.

The interactive workstation further comprises a keyboard, a mouse and a display device. The interactive workstation is arranged on the controlled terminal side and is used for being distributed to the interactive users and receiving and responding to the control instructions of the interactive users.

It should be noted that a session between a user and a machine may have multiple workstations, typically an interactive workstation (Winsta 0).

And step 504, the desktop is projected to the main control terminal through the video network, so that the main control terminal inputs a control instruction according to the desktop and sends the control instruction to the interactive workstation.

Specifically, when a plurality of users (master terminals) log in a machine (controlled terminal), a plurality of remote sessions are generated, and each remote session is associated with an interactive workstation of the remote session. Desktop pictures of different users at the controlled terminal are collected, and the desktop pictures are transmitted back to the respective logged main control terminals by using the video network. Control commands for multi-user operation may be transmitted to the respective interworking stations using the video network.

And 505, responding to the control instruction, and controlling the controlled terminal to execute the operation corresponding to the control instruction.

In particular, the hook function provided by the controlled terminal system may be employed to execute the control instruction. In this way we achieve multi-user remote operation using video networking.

According to the technical scheme provided by the embodiment, the remote control is realized by using the video network, and due to the characteristics of large bandwidth and zero delay of the video network, a plurality of persons can remotely control one server at the same time without mutual influence, so that a single server can be remotely operated by a plurality of persons at the same time, and the utilization rate of the server is improved; in addition, when the operation and maintenance deployment is carried out on the remote equipment, an operation and maintenance engineer can simultaneously deploy a plurality of systems of the remote equipment, so that the working efficiency is improved; in daily life, one person can use one computer to do different activities at the same time.

Referring to fig. 6, a flowchart illustrating steps of another remote control method provided in an embodiment of the present application is shown. Referring to fig. 8, a flowchart of a remote control method according to an embodiment of the present application is shown. The remote control method can be applied to the video network, and the video network can comprise a controlled terminal and a plurality of main control terminals.

step 601, receiving user names and passwords sent by each main control terminal through the video network.

Step 602, recording session identifiers between each main control terminal and the controlled terminal when the controlled terminal successfully logs in according to the user name and the password.

Specifically, the user can input a user name and a password on a remote control software interface of the main control terminal, and the user name and the password are transmitted to a controlled terminal such as a PC through the video network, the controlled terminal receives authentication information such as the user name and the password, and the controlled terminal invokes a bottom layer login interface through a program to simulate user login, and if the login is successful, the system records the session ID (session identifier) of the current time.

Step 603, create an interworking workstation and desktop corresponding to the session identification.

Specifically, after login is successful, an interactive workstation and a desktop under the interactive workstation are automatically created at the controlled terminal, and the interactive workstation and the desktop are bound with the session identifier. Wherein different sessions correspond to different desktops and interactive workstations.

And step 604, projecting the desktop to the main control terminal through the video network, so that the main control terminal inputs a control instruction according to the desktop and sends the control instruction to the interactive workstation.

In one implementation, the step may specifically include: starting a video network virtual terminal installed at a controlled terminal, wherein the video network virtual terminal allocates a corresponding video network box number for the session identifier; and (4) throwing the desktop to a main control terminal through the video network box number.

Specifically, a corresponding system process can be started, the virtual terminal is started, the corresponding relation between the login session identifier and the box number is recorded, a desktop snapshot is started, the desktop snapshot is sent back to the user client through the video network, and the desktop is projected to the client, so that the main control terminal inputs a control instruction according to the desktop.

Wherein, a plurality of desktops corresponding to each user are created by starting the system process, and necessary system processes are opened.

And step 605, responding to the control instruction, and controlling the controlled terminal to execute the operation corresponding to the control instruction.

In one implementation, the step may specifically include: and responding to the control instruction, calling a hook function, and controlling the controlled terminal to execute the operation corresponding to the control instruction.

By calling the hook function, the application program can filter all messages and events at a system level and access messages which cannot be accessed under normal conditions. A hook function is a program that handles system messages and is hooked into the system through a system call. The hook function comprises a local hook and a remote hook, the local hook only hooks events of your own process, and the remote hook can also hook events of other processes.

When the login on the controlled terminal is successful, and the processes of creating the interactive workstation, creating the desktop, starting the process, the virtual terminal, allocating the box number and the like are completed, the desktop is displayed on the client (the main control terminal), a user can input a control instruction through a mouse or a keyboard and send the control instruction to the interactive workstation of the controlled terminal through the video network, and the interactive workstation responds to the operation instruction (such as mouse protocol flow) to operate the desktop, calls a system hook function, simulates mouse and keyboard events, completes remote control, and refers to fig. 8 and 9.

Referring to fig. 7, a flowchart illustrating steps of another remote control method provided in an embodiment of the present application is shown. Referring to fig. 8, a flowchart of a remote control method according to an embodiment of the present application is shown. Referring to fig. 9, a flow chart of a transmission control command according to an embodiment of the present application is shown.
