In this specification, the definition of the label is similar to that of a label of MP L S (Multi-Protocol L abel Switch), and assuming that there are two connections between device a and device B, there are 2 labels for a packet from device a to device B, and there are 2 labels for a packet from device B to device a. the label is divided into an incoming label and an outgoing label, and assuming that the label (incoming label) of a packet entering device a is 0x0000, the label (outgoing label) of the packet leaving device a may become 0x 0001.
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 practical application, after the target state information corresponding to the target video network terminal is obtained, the data acquisition center can perform format conversion on the target state information according to a json format.
And a substep 22, returning the format-converted target state information to the Web server.
In practical application, the target state information after format conversion can be sent to the Web server. Since the target state information may be information identifying whether the target video network terminal sends the streaming data, the Web service side may obtain whether the target video network terminal has information on sending the streaming data according to the target state information to detect whether the terminal sends the streaming data.
In the embodiment of the invention, the first state query request which is sent by the Web server and comprises the server identifier of the target video network server and the terminal identifier of the target video network terminal is received, then the first state query request is responded, the target state information corresponding to the target video network terminal is obtained from the terminal information table of the target video network server, and then the target state information is returned to the Web server, so that the real-time detection of the terminal state is realized, the detection efficiency is improved, the normal operation of the terminal service is ensured, the real-time query of the state information of the terminal by operation and maintenance personnel and other systems is facilitated, and the labor cost and the operation and maintenance cost are reduced.
