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), and is defined to be the same as the Destination Address (DA);
reserved bytes consist 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 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., more than 2 connections between a node switch and a node server, between a node switch and a node switch, and between a node switch and a node server. However, the 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 application: 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 as follows: 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.
Based on the characteristics of the video networking, one of the core concepts of the embodiment of the application is provided, following the protocols of the video networking and the internet, a storage service system in the internet displays information of a plurality of video networking terminals acquired from a network management server in a list form, generates a monitoring request instruction according to selection operation on the list, sends the monitoring request instruction to a target video networking terminal, sends video networking video streaming data of the acquired target video networking terminal to a web video playing plug-in the storage service system, and plays a video by the web video playing plug-in, so that the video streaming data of the plurality of video networking terminals can be viewed and previewed on the storage service system.

For example, to select an a-view terminal 604 on the list of view terminals 604, the node at which the a-view terminal 604 is located in the list of view terminals 604 may be double clicked.
In a specific implementation, the user may perform the above-mentioned selection operation on the web page.
The target autonomous cloud server is used for sending the monitoring request instruction to a target video networking terminal corresponding to the target terminal number, and the target video networking terminal is used for sending the collected video networking video streaming data to the target autonomous cloud server according to the monitoring request instruction.
As an optional example of the embodiment of the present application, the storage service system 601 includes a plurality of virtual terminals, each of the virtual terminals has an idle state flag or a busy state flag, and step 504 may specifically be the following sub-steps:
in step 5041, the storage service system 601 searches for a target virtual terminal with an idle status flag from the plurality of virtual terminals.
The virtual terminals can be understood as software objects which can be accessed to the video network, and a plurality of virtual terminals exist in the storage service system 601; when a certain virtual terminal is not used for connecting the video network, the virtual terminal has an idle state mark; when the virtual terminal is used for connecting the video network, the virtual terminal is occupied, at the moment, the virtual terminal is marked to be in a busy state, and the storage server system can not call the virtual terminal any more.
Step 5042, the storage service system 601 sends the monitoring request command to the target virtual terminal.
The target virtual terminal is used for sending the monitoring request instruction to the target autonomous cloud server.
In the embodiment of the present application, the target virtual terminal is configured to send the monitoring request instruction, which may also be understood as that the virtual terminal performs data transmission between the storage service system 601 and the target autonomous server.
In step 5042, the storage service system 601 sets the idle status flag of the target virtual terminal to a busy status flag.
In the above optional example of the embodiment of the present application, the storage service system 601 receives, by using the target virtual terminal, video stream data of the video network forwarded by the target autonomous cloud server.
In practice, the virtual terminal performs transmission of video stream data of the video network between the storage service system 601 and the target autonomous server.
In step 506, the storage service system 601 converts the video stream data into internet video stream data supporting internet protocol, and sends the internet video stream data to the web video playing plug-in 707.

As an optional example of the embodiment of the present application, the storage service system 601 includes a callback function, and the video stream data of the video networking further includes a header of a monitoring play service type. Step 506 may specifically include the following sub-steps:
step 5061, the storage service system 601 extracts the header of the service type of the monitoring and playing from the video stream data of the video network.
The video networking service types can comprise conference recording, system cascading, web real-time monitoring and the like, when the virtual terminal receives video networking video stream data, the virtual terminal can distinguish which service is, and then calls different object processing; the callback function is understood to be a function called by a function pointer, the callback function is not directly called by an implementation party of the function, but is called by another party when a specific event or condition occurs, and is used for responding to the event or condition, in practice, the callback function can be used for processing video stream data of the video network differently according to different video stream data service types, so that the storage service system 601 can process a plurality of different video stream services, and the practicability of the storage service system 601 is improved.
In the embodiment of the application, the video stream data of the video network is of a monitoring playing service type, that is, the video stream data of the video network is data for monitoring playing, and the callback function can process the video stream data of the video network according to the requirement of the monitoring playing service.
In practice, if the video stream data of the video networking is the video stream data for conference recording, the callback function may further store the video stream data according to the service requirement for conference recording.
In step 5062, the storage service system 601 sends the video stream data and the header of the service type of the monitoring and playing to the callback function, where the callback function is configured to convert the video stream data into internet video stream data supporting an internet protocol according to the header of the service type of the monitoring and playing, and send the internet video stream data to the web video playing plug-in 707.
It can be understood that the video stream data all have a protocol header, and the protocol header of the video stream data of the video network is a video network protocol, and if the video stream data is played in the internet, the protocol header needs to be converted into an internet protocol. For example, in the video network, the protocol header of the video stream data is 4001, and in the internet, the protocol header of the video stream data is 01, so that the protocol header of 4001 needs to be converted into the protocol header of 01, so that the video stream data of the video network can be played in the environment of the internet.
As an optional example of the embodiment of the present application, after step 506, the following steps may further be included:
in step 507, the storage service system 601 generates a preview end instruction according to the received play stop operation for the web video play plug-in 707, and sends the preview end instruction to the target virtual terminal.
The target virtual terminal is used for sending the preview ending instruction to the target autonomous cloud server, the target autonomous cloud server is used for sending the preview ending instruction to the target video networking terminal, and the target video networking terminal is used for stopping sending the collected video networking video streaming data to the target autonomous cloud server according to the preview ending instruction.
In practice, when the watching of the monitoring video needs to be finished, the user may select to stop playing on the web video playing plug-in 707, and after the preview finishing instruction for stopping playing reaches the target video network terminal, the target video network terminal stops sending the collected video stream data, so that, compared with the case of stopping the video stream playing only on the web video playing plug-in 707, the technical means of stopping sending the video stream data of the video network when the web video playing plug-in 707 stops playing is adopted, the connection between the target virtual terminal and the target autonomous cloud server can be disconnected, and the transmission of the video stream data between the target autonomous cloud server and the target video network terminal is stopped, so that the target virtual terminal is released from working on the one hand, and on the other hand, the bandwidth flow of the video network is saved.
In step 508, the storage service system 601 resets the busy state flag of the target virtual terminal to the idle state flag.
In a specific implementation, after the target virtual terminal is marked as an idle state, the target virtual terminal may be subsequently used to perform monitoring and playing of other video networking terminals 604.
In the embodiment of the method for previewing the video stream, the storage service system 601 may utilize the web video playing plug-in 707 to play the monitoring videos of the multiple video networking terminals 604, so that the video networking terminals 604 are used as monitoring objects, the online states of the video networking terminals 604 may be monitored, and the unified monitoring management of the multiple video networking terminals 604 in the video networking is realized. And the storage server system is in the internet and can log in the internet, so that the videos of a plurality of video networking terminals 604 can be monitored in the internet, and the application range of the application is expanded.
