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 the types of different datagrams, 64 bytes if it is a packet of various protocols, 32+1024=1056 bytes if it is a packet of unicast data, and certainly 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 packet definition for metropolitan area networks

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 0x0001. 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, which is located between the reserved bytes and the payload of the packet.

Referring to fig. 5, a flowchart illustrating steps of a data processing method according to an embodiment of the present invention is shown, and the method may be applied to a first terminal device, where the first terminal device may be deployed with a first probe agent, and specifically includes the following steps:

step 501, acquiring a first data packet, and sending the first data packet to the first probe agent; the first data packet is a data packet adopting a first communication network protocol;

as an example, the first terminal device may be a computer having a video networking interface.

The first communication network Protocol may include an internet communication Protocol, and the internet communication Protocol may be a Transmission Control Protocol (TCP) or a User Datagram Protocol (UDP).

The TCP protocol may be a transport protocol designed to provide a reliable end-to-end byte stream on the internet, and the TCP data transmitted by using the TCP protocol may have a data format as shown in table 1:

TABLE 1

The first probe agent may be a network agent program, and may perform data transmission using different communication protocols after acquiring data, for example, may perform data conversion after acquiring data using an internet communication protocol to obtain data using a video networking communication protocol, or may convert data using the video networking communication protocol into data using the internet communication protocol after acquiring data using the video networking communication protocol; in the operation process, the first probe agent can create a virtual terminal, call a video network interface and access the video network by using the virtual terminal.

In a specific implementation, one or more applications may be installed in the first terminal device, and the applications may include application software and systems in the video network, such as a network management system, an operation and maintenance workstation, and the like. Since most hardware devices are designed and developed for the internet, when the application runs in the first terminal device, the first data packet, such as a TCP data packet or a UDP data packet, may be generated by using a transmission control protocol or a user datagram protocol, and the first data packet is communicated with application software in other terminal devices through the TCP data packet or the UDP data packet.

In the operation process of the first terminal device, a first data packet of the application may be acquired, and the first data packet may be sent to the first probe agent.

Step 502, determining a data type corresponding to the first data packet by using the first probe agent, and converting the first data packet into a second data packet according to the data type; the second data packet is a data packet adopting a second communication network protocol;

as an example, the data types may include a message type, a command type, and a file type.

The second communication network protocol may be an internet of view communication protocol, and the data transmitted using the internet of view communication protocol may have a data format as shown in table 2:

TABLE 2

In practical application, the first data packet may have a data type identifier, and after the first data packet is sent to the first probe agent, the first probe agent may be used to obtain the data type identifier, determine a data type corresponding to the identifier, and convert the first data packet into a data packet using the second communication network protocol according to the data type of the first data packet.

In an embodiment of the present invention, the step of converting the first data packet into the second data packet may include the following sub-steps:

In practical application, the first terminal device may store a corresponding relationship between an IP address and an address of the video network in advance, and the first data packet may include a destination IP address corresponding to the destination terminal device, for example, data corresponding to a "destination terminal number" field in the first data packet.

After the first data packet is obtained, the destination IP address can be analyzed from the first data packet, and the destination IP address in the first data packet is converted into the view networking address by combining the corresponding relationship between the IP address and the view networking address, so as to obtain a second data packet.

Step 503, sending the second data packet to a second terminal device through a second communication network.

As an example, the second terminal device may be a computer having a video networking interface, and the second terminal device may have a second probe agent disposed therein.

The second probe agent may be a network agent program, and may perform transmission through different communication protocols after obtaining the video networking data, for example, an internet communication protocol, and the second probe agent may create a virtual terminal in an operation process, and call a video networking interface, and access the video networking using the virtual terminal.

After converting the first data packet into the second data packet, the first terminal device may send the second data packet to the second terminal device through the second communication network, and the second terminal device may obtain the second data packet through the virtual terminal.

Specifically, after the first probe agent is used for data conversion to obtain the second data packet, the first probe agent may obtain the internet of view address corresponding to the virtual terminal from the second data packet, and send the first data packet to the virtual terminal corresponding to the internet of view address, so as to send the second data packet to the second terminal device.

In an embodiment of the present invention, the method may further include the steps of:

s1, receiving a third data packet sent by the second terminal equipment through the first probe agent, wherein the third data packet is a data packet adopting a second communication network protocol;

in a specific implementation, the second terminal device may send a third data packet using the second communication network protocol to the first terminal device, and the first terminal device may receive the third data packet through the first probe agent.

Specifically, the second terminal device may have one or more applications installed therein, and the second terminal device may obtain a data packet of the application using the first communication network protocol, convert the data packet into a third data packet using the second communication network protocol, and send the third data packet to the first terminal device.

S2, converting the third data packet into a fourth data packet by utilizing the first probe agent; the fourth data packet is a data packet adopting a first communication network protocol;

after receiving the third data packet, since the third data packet adopts the second communication network protocol and the application in the first terminal device mainly adopts the data packet of the first communication network protocol, the first terminal device may convert the third data packet into a fourth data packet adopting the first communication network protocol by using the first probe agent.

And S3, sending the fourth data packet to a corresponding application.

After the conversion, the first terminal device may send the fourth data packet to the corresponding application through the first probe agent.

In an embodiment of the present invention, step S3 may include the following sub-steps:

determining a data type of the fourth data packet; and sending the fourth data packet to a corresponding application according to the data type.

In particular implementations, the data type of the fourth data packet may include a message type, a command type, or a file type. After the first probe agent converts the data, the data type can be determined, and the third data packet is sent to the corresponding application according to the data type of the fourth data packet, so that the application can read the corresponding message and execute the command, or store the file to the address corresponding to the second application client.

In order to enable those skilled in the art to better understand the above steps, the following is an example to illustrate the embodiments of the present invention, but it should be understood that the embodiments of the present invention are not limited thereto.

As shown in fig. 6, other systems and probe agents (i.e., first probe agents) may be deployed in the host 1 (i.e., first terminal device), and other systems and probe agents (i.e., second probe agents) may also be deployed in the host 2 (i.e., second terminal device). In the invention, a probe agent in a host 1 accesses the video network by establishing a virtual terminal 1, and a probe agent in a host 2 accesses the video network by establishing a virtual terminal 2, so as to reduce the reconstruction of the application and the system and achieve the purpose of data transmission through the video network.

In particular, other systems in host 1 may receive or generate TCP data (i.e., the first packet) and send the TCP data to the probe agent in the same host. After acquiring the TCP data, the probe agent may convert the TCP data into V2V data (i.e., a second data packet) using a video networking communication protocol, and send the V2V data to the host 2 through the virtual terminal 1.

In the host 2, the probe agent acquires V2V data transmitted by the host 1 through the virtual terminal 2, and may convert the V2V data into TCP data and then transmit it to other systems.

As shown in fig. 7, in the data transmission process, other systems in the host 1 may send TCP data to the probe agent in the same host, and after the probe agent receives non-V2V data, it may be determined that the data is from other systems in the host and needs to be transmitted to another host using an internet of view protocol, data processing may be performed to convert the TCP data into V2V data, and send the V2V data to the probe agent in the host 2 through the internet of view.

After the probe agent in the host 2 receives the V2V data, it may determine that the data is from another host (i.e., the host 1) and needs to be sent to other systems in the local computer, and then may convert the V2V data to obtain TCP data, and further send the TCP data to other systems in the host 2.

The method realizes the conversion of TCP data and V2V data, and data transmitted by an IP network can be converted into data transmitted in a video network by using data transmission comprising two communication protocols.

In the embodiment of the invention, a first data packet is obtained and sent to a first probe agent, wherein the first data packet is a data packet adopting a first communication network protocol; the data type corresponding to the first data packet is determined by adopting the first probe agent, the first data packet is converted into the second data packet according to the data type, the second data packet is a data packet adopting a second communication network protocol, and the second data packet is sent to the second terminal equipment through the second communication network, so that the data interaction between the video networking applications is completed by utilizing the video networking, the internet is not required to be relied on when the video networking applications are interacted, and the high-speed and safe data transmission can be carried out on the video networking.

Referring to fig. 8, a flowchart illustrating steps of another data processing method according to an embodiment of the present invention is shown, where the method may be applied to a first terminal device, and the first terminal device may be deployed with a first probe agent, and the method specifically includes the following steps:

step 801, acquiring a first data packet, and sending the first data packet to the first probe agent; the first data packet is a data packet adopting a first communication network protocol;

step 802, determining a data type corresponding to the first data packet by using the first probe agent;

step 803, when the data type is a message type, determining a first data length corresponding to the first data packet;

specifically, the first data packet may have a data type identifier, and after the first probe agent obtains the first data packet, the data type identifier may be read. The data packets of different data types may have different ranges of data lengths, and when the data type is identified as a message type, the data length corresponding to the first data packet may be further determined.

As an example, when the internet communication protocol is a TCP protocol, and the data type of the TCP data is a message type, the TCP data may have a data format as shown in the following table:

protocol	Destination port	Message content
			char[8]	int	char[]

TABLE 3

In practical applications, the TCP data may include a protocol field, a destination port field, and a message content field, where the protocol field may identify a transit protocol used by the first data packet, such as a TCP protocol or a UDP protocol; the destination port field may correspond to a port identification of an application in the terminal device. Before data transmission, port identifiers corresponding to different applications can be preset, and when a data packet is sent to an application, the corresponding application can be determined through a destination port.

Step 804, determining whether the first data length is greater than a preset first length threshold, if so, executing step 805, otherwise, executing step 806;

specifically, in the first data packet adopting the first communication network protocol, the data length may be any length with an indefinite length, while in the transmission of the data packet adopting the second communication network protocol, the data packet has a fixed data length, which may be a first length threshold, for example, the data length of the data packet of each message type is fixed to be 800 bytes.

After determining the first data length, it may be determined whether the first data length is greater than a preset length threshold, if so, step 805 may be performed, and if not, step 806 may be performed.

As an example, data employing a video networking communication protocol (i.e., V2V data) may have a data format as shown in table 4:

protocol	Destination port	Identification	Sequence number of fragments	Total number of fragments	Message content
						char[8]	int	char[40]	int	int	char[800]

TABLE 4

Step 805, fragmenting the first data packet to obtain a plurality of first fragmented data, and encapsulating the plurality of first fragmented data into a plurality of second data packets; the second data packet is a data packet adopting a second communication network protocol;

when it is determined that the first data length is greater than the preset first length threshold, the first data packet may be fragmented, the data length of the plurality of first fragmented data obtained after fragmentation is made to be the preset length threshold, and the plurality of first fragmented data are encapsulated into a plurality of second data packets.

In an example, when a plurality of first fragment data are encapsulated into a second data packet, a data packet identification field, a fragment sequence number and a fragment total number may be added to the second data packet, so that a plurality of second data packets may be subsequently spliced and restored to original data. The packet identifier field may identify that a plurality of second packets are obtained by fragmenting the same first packet, the fragmentation sequence number may determine an order of a second packet in the plurality of second packets, and the total fragmentation number may determine the total number of the second packets.

Step 806, converting the first data packet into a second data packet; the second data packet is a data packet adopting a second communication network protocol;

when the first data length is determined not to exceed the length threshold value, the data length of the first data packet is determined not to exceed the data length allowed to be transmitted in the video network, and the first data packet can be directly converted into the second data packet without being fragmented.

In an example, when fragmentation processing is not required for the first packet, the total number of fragments may be set to 1.

Step 807, the second data packet is sent to the second terminal device through the second communication network.

After the conversion, the first terminal device may send the second data packet to the second terminal device through the second communication network.

In practical application, the first terminal device may further receive a third data packet, which is sent by the second terminal device and has a data type of a message type. When the data type is the message type, the first terminal device may determine a plurality of third data packets having the same identification field, sequentially combine the plurality of third data packets according to the fragmentation sequence number, and convert the third data packets into a fourth data packet using the first communication network protocol.

After the fourth data packet is obtained, the first terminal device may obtain a port identifier corresponding to the destination port field from the fourth data packet, and send the fourth data packet to an application corresponding to the port identifier, so that after the fourth data packet is received, the corresponding application in the first terminal device may read message content from the fourth data packet.

As shown in fig. 9, when the probe agent receives data whose data type is a message type, if the data is non-V2V information (i.e., a data packet using a first communication network protocol), it may first determine whether the information length exceeds a preset length threshold, and if so, may first fragment the non-V2V information, and then encapsulate the information into V2V format information (i.e., a data packet using a second communication network protocol) for transmission.

When the message received by the probe agent is the V2V information (i.e. a data packet adopting the second communication network protocol), the information fragments with the same identification field can be spliced in sequence to obtain the restored non-V2V information, and the restored non-V2V information is sent to the application corresponding to the destination port.

In the embodiment of the invention, when the data type is the message type, the first data length corresponding to the first data packet is determined, whether the first data length is larger than a preset first length threshold value is judged, if so, the first data packet is fragmented to obtain a plurality of first fragment data, the plurality of first fragment data are packaged into a plurality of second data packets adopting a second communication network protocol, and the second data packets are sent to the second terminal equipment, so that the message forwarding among the video networking applications is completely carried out through the video networking, when the internet data length is larger than the preset threshold value, the data are fragmented, the fragment data are converted into the video networking data, the dependence on the internet when the applications in the video networking send the messages is reduced, and the transmission advantages of the video networking are more effectively exerted.

Referring to fig. 10, a flowchart illustrating steps of another data processing method according to an embodiment of the present invention is shown, which may be applied to a first terminal device, where the first terminal device may be deployed with a first probe agent, and specifically includes the following steps:

1001, acquiring a first data packet, and sending the first data packet to the first probe agent; the first data packet is a data packet adopting a first communication network protocol;

step 1002, determining a data type corresponding to the first data packet by using the first probe agent;

step 1003, when the data type is a file type, acquiring a file storage path from the first data packet;

after determining the data type, when the data type is a file type, a file storage path may be obtained from the first data packet.

Specifically, because the application in the first terminal device and the first probe agent are deployed in the same host, when the application in the first terminal device sends the file data in the first terminal device to other terminal devices, the file data can be directly obtained from the first probe agent by the first terminal device, and the application in the first terminal device does not need to send the complete file data to the first probe agent and then the complete file data is sent to other terminal devices by the first probe agent. Based on this, when the first probe agent receives the first data packet with the data type of the file type, the file storage path can be read from the first data packet.

In an example, when the data type is a file type, the first data packet using the TCP protocol may have the following data format:

native path	Destination path
		char[256]	char[256]

TABLE 5

In an example, the first data packet may only include a destination path to which the file data is to be sent, and a corresponding storage path of the file data in the first terminal device.

Step 1004, obtaining file data corresponding to the file storage path, and converting the file data into a second data packet; the second data packet is a data packet adopting a second communication network protocol;

after obtaining the file storage path, the first probe agent may obtain file data corresponding to the file storage path from the first terminal device, and convert the file data into the second data packet.

As an example, when the data type is a file type, the second data packet using the second transmission protocol may have a data format as shown in table 6:

destination path	Identification	Sequence number of fragments	Total number of fragments	File data
					char[256]	char[40]	int	int	char[700]

TABLE 6

In an embodiment of the present invention, the step of converting the file data into the second data packet may include the following sub-steps:

substep 11, obtaining a second data length corresponding to the file data;

since the data length of the data in the video network can be a fixed length, and the data length of the file data is not fixed, after the file data is obtained, a second data length corresponding to the file data can be obtained.

A substep 12, judging whether the second data length is larger than a preset second length threshold value; if yes, executing substep 13, if not, executing substep 14;

in practical applications, the data length of the file data may be any length with an indefinite length, and when a second communication network protocol is used for the data packet of the message type, the second data packet may have a fixed data length, where the length may be a second length threshold, and the second length threshold may be equal to or different from the first length threshold.

After the second data length is determined, it may be determined whether the second data length is greater than a preset second length threshold, if yes, performing substep 13, and if no, performing substep 14.

Substep 13, fragmenting the file data to generate a plurality of second fragmented data, and encapsulating the plurality of second fragmented data into a plurality of second data packets;

when it is determined that the second data length is greater than the second length threshold, the file data may be fragmented, the data length of the second fragmented data obtained after fragmentation is made to be the preset length threshold, and the second fragmented data is encapsulated into a second data packet.

In an example, when a plurality of second fragment data are encapsulated into a second data packet, a data packet identification field, a fragment sequence number and a fragment total number may be added to the second data packet, so as to splice the plurality of second data packets and restore the second data packets to the original data.

Substep 14, converting said file data into a second data packet.

When the second data length is determined not to exceed the second length threshold, the data length of the file data is determined not to exceed the data length allowed to be transmitted in the video network, and the file data can be directly converted into the second data packet without being fragmented.

Step 1005, sending the second data packet to a second terminal device through a second communication network.

In practical application, the first terminal device may further receive a third data packet with a file type data type sent by the second terminal device. When the data type is a file type, a plurality of third data packets with the same identification field may be determined, and the plurality of third data packets are sequentially combined according to the fragment sequence number and converted into a fourth data packet containing file data, where the fourth data packet may be a data packet using a first communication network protocol.

After obtaining the fourth data packet, the first terminal device may obtain a destination path from the fourth data packet, and send the fourth data packet to an address storage file data corresponding to the destination path, where the destination path may be a storage path corresponding to a related application in the first terminal device.

As shown in fig. 11, when receiving data whose data type is a file type, if the data is a non-V2V file (i.e., a first data packet including a file storage path), the probe agent may determine that the data is from an application client in the same terminal device, based on this, may read local file data from the terminal device according to a file storage address in the non-V2V file, and determine whether the data length exceeds a preset length threshold, and if the data length exceeds the preset length threshold, may fragment the file data, and then encapsulate the file data into a second data packet in a V2V format to send the second data packet.

If the data received by the probe agent is a V2V file (i.e., a third data packet), the second data packets with the same identification fields may be sequentially spliced to obtain a restored non-V2V file (i.e., a fourth data packet), and the restored non-V2V file is sent to a destination path corresponding to the relevant application in the first terminal device for storage.

In the embodiment of the invention, the file forwarding between the video network applications through the video network is completely realized by acquiring the first data packet of the first communication network protocol adopted by the first application client, sending the first data packet to the first probe agent, determining the data type corresponding to the first data packet by adopting the first probe agent, acquiring the file storage path from the first data packet when the data type is the file type, acquiring the file data corresponding to the file storage path, converting the file data into the second data packet adopting the second communication network protocol, and sending the second data packet to the second terminal equipment through the second communication network, so that the data transmission is carried out without depending on the internet, and the advantage of high-speed safe data transmission of the video network can be fully exerted.

Referring to fig. 12, a flowchart illustrating steps of a data processing method according to an embodiment of the present invention is shown, and the method may be applied to a first terminal device, where the first terminal device may be deployed with a first probe agent, and specifically includes the following steps:

step 1201, acquiring a first data packet, and sending the first data packet to the first probe agent; the first data packet is a data packet adopting a first communication network protocol;

step 1202, determining a data type corresponding to the first data packet by using the first probe agent;

step 1203, when the data type is a command type, converting the first data packet into a second data packet; the second data packet is a data packet adopting a second communication network protocol;

after the data type is determined, when the data type is the command type, the first data packet can be directly converted into a second data packet adopting a second communication network protocol without fragmentation because the data length of the command is smaller than a preset length threshold value.

As an example, the first packet of the command type may have a data format as shown in the following table:

command
	char[512]

TABLE 7

Step 1204, sending the second data packet to a second terminal device through a second communication network.

In practical applications, the first terminal device may further receive a third data packet, which is sent by the second terminal device and has a data type of a command type. After receiving the third data packet with the data type of the command type, the first terminal device may convert the third data packet into a fourth data packet with the first communication network protocol by using the first probe agent, and send the fourth data packet to a corresponding application in the first terminal device, so that the application executes the command in the fourth data packet.

As shown in fig. 13, when the probe agent receives the data with the data type of the command type, if the data is a command (i.e., a first data packet) with a non-V2V format, the probe agent may convert the command with the non-V2V format to obtain a command (i.e., a second data packet) with a V2V format, and send the command to the second terminal device.

When the probe agent receives the command in the V2V format (i.e., the third packet), the command may be converted into a command in a non-V2V format (i.e., the fourth packet), and sent to the corresponding application, so that the application executes the command.

In the embodiment of the invention, the first data packet is obtained and is a data packet adopting a first communication network protocol, the first probe agent is adopted to determine the data type corresponding to the first data packet, when the data type is a command type, the first data packet is converted into a second data packet adopting a second communication network protocol, and the second data packet is sent to the second terminal equipment through the second communication network, so that the command forwarding between the video networking applications is completely carried out through the video networking, the data transmission is carried out without depending on the Internet, and the advantage of high-speed safe data transmission of the video networking can be fully exerted.
