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 Java layer is realized through Java language, and the local layer is realized through C and C + + languages. The interaction between the Java layer and the Native layer may be implemented by a JNI (Java Native Interface) mechanism.

The internet terminal generating the internet protocol-based status query request packet may include a 1-A3:
a1, the Internet terminal obtains the terminal information to be inquired in String format through Java layer, and converts the terminal information to be inquired in String format into the terminal information to be inquired in JSON format.
After the user inputs the information of the terminal to be inquired, the internet terminal can form the information of the terminal to be inquired into the information of the terminal to be inquired in a String format through a Java layer, and the String format is a character String format.
The terminal information to be queried may include information of a plurality of terminals of the video network, so that the terminal information to be queried in String format can be converted into the terminal information to be queried in JSON format through the Java layer. JSON (JavaScript Object Notification) is a lightweight data exchange format. JSON can convert a set of data into a string. JSON is built in two structures: a collection of "name/value" pairs (A collection of name/value pairs). In different languages, it is understood as an object (object), a record (record), a structure (struct), a dictionary (dictionary), a hash table (hash table), a keyed list (keyed list), or an associative array (associative array). 2. An ordered list of values (ordered list of values). In most languages, it is understood as an array (array). The JSON format in the embodiment of the invention can be a JSON array format.

A3, the Internet terminal obtains the status query request packet based on the Internet protocol through the local layer encapsulation, and adds the information of the terminal to be queried to the status query request packet based on the Internet protocol.
The Internet terminal and the Protocol conversion server interact with each other based on an Internet Protocol, such as a Transmission Control Protocol (TCP)/Internet Protocol (IP). The internet terminal encapsulates the state query request into an internet protocol-based state query request packet based on the internet protocol, and adds the information of the terminal to be queried to the internet protocol-based state query request packet. For example, the terminal information to be queried is added to the internet packet header of the status query request packet, and is spliced with the IP address, the port number, and the like in the internet packet header. The internet terminal sends the state query request packet based on the internet protocol to the protocol server through the internet.
Step 502, the protocol conversion server converts the status query request packet based on the internet protocol into a status query request packet based on the video networking protocol, and sends the status query request packet based on the video networking protocol to the video networking server.
The protocol conversion server and the video network server interact based on a video network protocol. After receiving a state query request packet based on an internet protocol sent by an internet terminal, the protocol conversion server converts the state query request packet based on the internet protocol into a state query request packet based on a video networking protocol. The conversion process may be specifically performed by an idle virtual terminal therein.
The step of converting the internet protocol-based status query request packet into an internet protocol-based status query request packet by the collaboration server may include: the cooperation server analyzes the state query request packet based on the Internet protocol and extracts the information of the terminal to be queried from the Internet packet header of the state query request packet based on the Internet protocol; and the protocol conversion server adopts the video networking protocol to package to obtain the state query request packet based on the video networking protocol, and adds the terminal information to be queried to the video networking packet header of the state query request packet based on the video networking protocol.
The protocol conversion server analyzes the state query request packet based on the internet protocol to obtain unpacked state query request data, extracts the information of the terminal to be queried from the packet header of the internet, then packages the state query request data by using the video networking protocol, and adds the information of the terminal to be queried in the packet header of the video networking. The head of the video network packet may further include a terminal number, an MAC address, and the like of a coordination server (specifically, a virtual terminal that processes the status query request packet currently), and the terminal information to be queried may be spliced with the terminal number and the MAC address.
Step 503, the protocol conversion server receives a status query response packet based on the video networking protocol returned by the video networking server; and the state inquiry response packet carries the state information of the video network terminal corresponding to the information of the terminal to be inquired.
After the video network terminal is registered in the video network server, the video network terminal sends heartbeat information to the video network server through a heartbeat mechanism (heartbeat means socket short connection, and is checked once a second) in a video network protocol, and the video network server can know whether the video network terminal is on line or not according to the heartbeat information.
After receiving a state query request packet based on a video networking protocol sent by a protocol conversion server, the video networking server extracts the information of the terminal to be queried from the state query request packet based on the video networking protocol, and acquires the state information of the video networking terminal corresponding to the information of the terminal to be queried. For example, if the state of the video networking terminal corresponding to the terminal information to be queried is online, the state information of the video networking terminal is 1, and if the state of the video networking terminal corresponding to the terminal information to be queried is online, the state information of the video networking terminal is 0. And the video network server generates a state query response packet which carries the state information of the video network terminal corresponding to the information of the terminal to be queried and is based on the video network protocol. And the video network server returns a state inquiry response packet based on the video network protocol to the protocol conversion server.

Step 504, the protocol conversion server converts the status query response packet based on the video networking protocol into a status query response packet based on the internet protocol, and returns the status query response packet based on the internet protocol to the internet terminal.
