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.

The control command can be used for controlling the video networking terminal; the query command can be used for performing operation query operation on the video network terminal, such as viewing the operating condition of the video network terminal. The identifier of the terminal of the video network may be a unique identifier of the terminal of the video network in a database, such as an Identification (ID) of the terminal of the video network.
After receiving the request message, the first network management server may forward the request message to the second network management server, for example, may forward the request message to the second network management server through the local area network.
Step 602, after receiving the request information, the second network management server generates the video networking protocol information according to the request information, and sends the video networking protocol information to the video networking server.
In one embodiment, after receiving the request message, the second webmaster server may start a database transaction based on the request message, determine a Media Access Control (MAC) address of the video network server, and then assemble the MAC address of the video network server and the received request message into video network protocol information, and send the video network protocol information to the video network server to wait for receiving a reply from the video network server.
In an optional embodiment of the present invention, the generating, by the second network management server, the internet protocol information according to the request information may include: extracting identification and operation commands of the video network terminal from the request information; determining the address of the appointed network card of the video network server according to the identifier of the video network terminal; and packaging the specified network card address and the operation command according to a video networking protocol to generate video networking protocol information.
It should be noted that one video network server may have two network cards, and may number the two network cards, for example, one network card is numbered as 0 port, and the other network card is numbered as 1 port. Wherein, port 0 is used for connecting video network, and port 1 is used for connecting LAN. The designated network card address in this embodiment may be used to represent an address of a network card used for connecting a local area network in the video network server, such as 1 port MAC of the video network server.

Specifically, after sending the video networking protocol information, the second network management server can judge whether an execution success result returned by the video networking server for the video networking protocol information is received within a preset time. If an execution success result returned by the video network server is received within the preset time, the operation command in the request information can be determined to be successfully executed, and corresponding success result information is generated; if the execution success result returned by the video network server is not received within the preset time, for example, the execution failure result returned by the video network server is received within the preset time, or the operation result returned by the video network server is not received within the preset time, it may be determined that the operation command in the request information fails to be executed, and corresponding failure result information is generated.
The second network management server can return the generated result information to the first network management server through the local area network, so that the result information is fed back to the main control equipment through the first network management server.
Step 604, after receiving the result information, the first network management server feeds back the result information to the main control device.

The second network management server generates result information according to the operation result returned by the video network server, and the result information comprises the following steps: extracting the running information from the query result; and generating corresponding query result information by adopting the operation information and the basic information.
Referring to fig. 8, a flowchart illustrating steps of a method for controlling a terminal of a video network according to an example of the present invention specifically includes the following steps:
step 801, a network management mobile phone APP in the master control device sends an inquiry request to a network management mobile phone server through the internet, where the inquiry request carries an identifier and an inquiry command of a video networking terminal.
Specifically, the user may request the network management mobile server to check the operation status of the video networking terminal, such as whether the video networking terminal is online, a program version, and basic information of the video networking terminal, through the network management mobile APP in the main control device.
Step 802, the network management mobile phone server forwards the received query request to a second network management server.
And step 803, the second network management server sends the protocol information of the video network terminal to the video network server according to the query request.
In this example, after receiving the query request, the second network management server may extract the terminal ID of the video network and the query command from the query request, and may perform query and modification operations on the network management data according to the query command. Specifically, the basic information of the video network terminal and the 1 port MAC of the video network server corresponding to the video network terminal can be inquired from the network management database according to the video network terminal ID, then the 1 port MAC, the inquiry command and the video network terminal ID can be assembled into video network protocol information according to a video network protocol, and the video network protocol information is sent to the video network server so as to inquire the running information of the video network terminal from the video network server. The basic information of the video network terminal may include system basic parameters such as a name, longitude and latitude, maintainer information, installer information, activation time, a content server address, a picture http path, an administrative area code, and the like, which is not limited in the embodiment of the present invention.
And step 804, the video networking server performs query operation on the video networking terminal based on the query command in the video networking protocol information to obtain a query result, and returns the query result to the second network management server.
Specifically, the video network server may query the video network terminal according to the query command, such as whether the video network terminal is online, program version, cascade status, and the like, to obtain the operation information of the video network terminal, and send the operation information as a query result to the second network management server.
Step 805, the second network management server returns corresponding query result information to the network management mobile phone server according to the query result returned by the video network server.
In a specific implementation, the second network management server may return the received operation information of the video network terminal and the basic information of the video network terminal stored in the network management database to the network management mobile phone server as query result information.
Step 806, the network management mobile phone server forwards the query result information returned by the second network management server to the network management mobile phone APP in the main control device.
For example, after receiving the query result information returned by the second network management server, the network management mobile phone server returns the query result information to the network management mobile phone APP in the main control device, so that the query result information is fed back to the user through the network management mobile phone APP, and the user can conveniently check and know the operating condition of the video networking terminal.
Certainly, the user may also use the network management mobile phone APP in the main control device to control the video network terminal, which may specifically include control operations such as restarting a service of the video network terminal, opening or closing a service of the video network terminal, modifying configuration, and the like. The modifying configuration refers to modifying modifiable items of the video networking terminal, such as modifying affiliated items of the video networking terminal, a terminal service state, a Media Access Control (MAC) address, a device identifier, geographical location information, operator information, an Internet Protocol (IP) address, a terminal type, installer information, maintainer information, a terminal type, and the like.
As another example of the present invention, when a user uses a network management mobile phone APP in the master control device to control a video network terminal, the network management mobile phone APP may generate a corresponding control request by using a video network terminal ID and a control command, and send the control request to a network management mobile phone server. Wherein, the control command may include: the command for restarting, opening, and closing the service may further include a command for modifying the configuration, which is not limited in this embodiment of the present invention.
For example, when the user restarts the service of the video networking terminal, the network management mobile phone APP may send the video networking terminal ID and the command for restarting the service to the network management mobile phone server; for another example, when the user closes (or opens) the service of the video networking terminal, the network management mobile phone APP may send the video networking terminal ID and the command to close (or open) the service to the network management mobile phone server; for another example, when the user modifies a modifiable item of the video network terminal, the network management mobile phone APP may generate a control request for the modifiable item, the modification command, and the video network terminal ID, and send the control request to the network management mobile phone server.
After receiving the control request sent by the network management mobile phone APP, the network management mobile phone server may forward the control request to the second network management server. After receiving the control request, the second network management server can query 1 port of MAC of the video network server corresponding to the video network terminal in a database by virtue of the video network terminal ID in the control request, then assemble the 1 port of MAC and the control command in the control request into video network protocol information, send the video network protocol information to the corresponding video network server, and wait for receiving the reply of the video network server.
For example, when the control command is a command to restart, open or close a service, the second network management server may assemble the queried 1-port MAC of the video network server and the received command into video network protocol information, send the video network protocol information to the video network server, and wait to receive a reply from the video network server. If the second network management server waits for the response of the video network server to overtime, overtime failure information can be returned to the network management mobile phone server. If the operation result replied by the video network server is received, the result information corresponding to the operation result can be returned to the network management mobile phone server.
For another example, when the control command is a command for modifying the configuration, the second network management server may update basic information of the video network terminal in the database by using the video network terminal ID, such as updating one or more of names, longitudes and latitudes, maintainer information, installer information, activation timeliness, content server addresses and/or groups of the video network terminal; and the inquired 1 port MAC of the video network server and the received commands for modifying project information and configuration, such as the server issued bandwidth, uplink and downlink rated bandwidth, menu and the like, can be assembled into video network protocol information, and the video network protocol information is sent to the video network server to wait for the reply of the video network server. Specifically, if the second network management server waits for the response of the video network server to timeout, the second network management server can roll back the database and return timeout failure information to the network management mobile phone server. If an operation failure result returned by the video network server is received, the database can be rolled back, and failure result information corresponding to the operation failure result is returned to the network management mobile phone server. If the successful operation result returned by the video network server is received, the database can be submitted, and the successful result information corresponding to the successful operation result can be returned to the network management mobile phone server.
And after receiving the result information returned by the second network management server, the network management mobile phone server returns the result information to the network management mobile phone APP. And the network management mobile phone APP presents the returned result information to the user.
