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 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

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.

In this embodiment, the access server may be a video network server, and the operation terminal may be a video network terminal or a user terminal. The number of the access servers can be adjusted according to actual needs, and the number of the operation terminals can also be adjusted according to actual needs. Optionally, in this embodiment, an access server and an operation terminal are taken as examples.

In a specific implementation, the at least one access server and the at least one operation terminal can establish connection through a video networking protocol.

The method specifically comprises the following steps:

step 501, the access server receives a dragging instruction sent by the operation terminal.

In a specific implementation, if there is one access server, one operation terminal, where the operation terminal is a video network terminal and the access server is a video network server. The operation terminal can send a connection request to the access server, specifically, the operation terminal can send the connection request to the video networking protocol conversion server, the video networking protocol conversion server can obtain a connection address of the connection request, and the video networking protocol conversion server sends the connection request to the access server corresponding to the connection address according to the connection address. The access server may establish a connection with the operation terminal according to the connection request. Thereby the access server establishes remote connection with the operation terminal. Preferably, the access server may be provided with a built-in display screen. After the operation terminal is connected with the access server, the operation terminal carries out remote control on the access server, sends an operation instruction to the access server, operates in the access server according to the operation instruction module, and displays a simulated operation result in the display screen.

Optionally, in a specific implementation, after the connection is established, the operation terminal sends a drag instruction to the access server. The sent drag instruction may include an operation instruction of the operation terminal, or may be an action instruction, or may be an address instruction, a data instruction, an action event, and the like. The access server can simulate the action of the operation terminal according to the dragging instruction and display the action of the operation. Optionally, the drag instruction sent by the operation terminal may be sent one or more at a time, and preferably, may be sent one at a time. Each dragging instruction comprises data such as an operation action, an operation event, an instruction address and the like, so that the access server can simulate the dragging action according to a single dragging instruction in each sending process.

In one example of this embodiment, after one access server is connected to multiple operation terminals, a drag instruction sent by the operation terminals may include a priority field, and the access server may obtain the field in the drag instruction, determine a priority corresponding to the field according to the field, determine a field with a highest priority, and preferentially simulate the drag instruction corresponding to the field with the highest priority. Actions in the drag instruction may also be simulated in sequence according to the priority of the fields.

Specifically, if the access server is connected to a plurality of operation terminals, the access server also executes the operation terminals in sequence according to the sequence of the drag instruction. In this embodiment, the drag instruction may further include movement information, and the movement information may include a start coordinate point or a target coordinate point of the mouse, and the like. The drag instruction may also include address information or verification information, etc.

Step 502, the access server responds to the dragging instruction to generate a mouse down event, a mouse moving event and a mouse up event.

The access server may also parse the drag instruction, and generate an operation event according to the drag instruction, where in this embodiment, the operation event may include a mouse down event, a mouse moving event, a mouse up event, a mouse click event, a mouse double click event, an event triggered when the mouse moves, an event triggered when the mouse leaves a certain object range, and the like.

In specific implementation, the operation terminal may receive a response dragging instruction sent by the access server, set a predetermined time in the operation terminal, and if the response dragging instruction sent by the access server is not received within the predetermined time, the operation terminal may also send a dragging instruction to the access server, and the operation terminal may also continuously send the dragging instruction to the access server within a preset time, where the preset time may be adjusted according to actual needs.

Step 503, executing the mouse down event, the mouse moving event and the mouse up event in sequence;

in a specific implementation, the access server may sequentially execute a mouse down event, a mouse move event, and a mouse up event, thereby implementing a drag effect.

For example, after receiving the drag instruction, the access server may simulate a drag effect according to the drag instruction, execute a mouse down event, execute a mouse up event, and finally execute the mouse up event, and in a display screen of the access server, a cursor moves according to the mouse down event, the mouse up event, and moves according to a path of the mouse down event, so that the drag effect of the mouse may be displayed on the display screen.

In an optional embodiment of the present invention, the access server receives a drag instruction sent by the operation terminal, then the access server responds to the drag instruction to generate a mouse down event, a mouse moving event and a mouse up event, and then the access server sequentially executes the mouse down event, the mouse moving event and the mouse up event. This application can let operation terminal and access server establish fast and be connected, let operation terminal carry out remote control to the access server, realize remote control, can pull through the interface when remote control and realize long-range pulling, can reduce transmission mouse operating instruction when pulling, realize the distal end of single instruction and pull the effect, also can reduce the delay of remote control simultaneously, the picture card that reduces the remote control appearance is pause with insensitive phenomenon, the sensitivity of improvement remote control, user's use experience is increased.
