Referring to fig. 2, a flowchart illustrating steps of a conference entering method of a monitoring camera according to an embodiment of the present invention is shown, where the method may be applied to the system shown in fig. 1, and the method may specifically include the following steps:

in step S101, the internet terminal sends an acquisition request to the video networking conference management server, where the acquisition request is used to acquire camera identifiers of multiple monitoring cameras managed by the video networking collaboration server;

so that the video network conference management server forwards the acquisition request to the video network coordination server, and receives a plurality of camera identifications sent by the video network coordination server according to the acquisition request;

in the process of a user at an internet terminal of the internet of things, if a part of monitoring cameras in a plurality of monitoring cameras managed by an internet of things coordination server need to be invited to participate in the internet of things conference, camera identifications of the part of monitoring cameras need to be obtained generally, and then the management server of the internet of things conference requests the part of monitoring cameras to be pulled into the internet of things conference according to the camera identifications of the part of monitoring cameras.

However, for the security of information, the video networking protocol server is only open to the video networking, but not to the external network, for example, not to the internet, and the internet terminal is not located in the video networking, therefore, the internet terminal cannot directly interact with the video networking protocol server, and also cannot directly obtain the camera identifiers of part of the monitoring cameras in the plurality of monitoring cameras managed by the video networking protocol server from the video networking protocol server, and then cannot request the video networking conference management server to pull part of the monitoring cameras into the video networking conference.

Therefore, in order to pull part of the monitoring cameras into the video networking conference, in the application, the internet terminal can indirectly interact with the video networking coordination server through the video networking conference management server, so that camera identifications of a plurality of monitoring cameras managed by the video networking coordination server can be indirectly acquired from the video networking coordination server through the video networking conference management server, and then a user can select the camera identifications of the part of the monitoring cameras needing to be invited to participate in the video networking conference from the camera identifications of the plurality of monitoring cameras, and request the video networking conference management server to pull part of the monitoring cameras into the video networking conference according to the camera identifications of the part of the monitoring cameras.

The video networking conference management server is provided with an interactive interface for the outside, for example, the internet is provided with an interactive interface, the interactive interface can be an interface for the outside to acquire information from the video networking conference management server, only an interface for reading information is used, and the interface is not an interface for writing information, and the information of the video networking conference management server and other equipment in the video networking conference cannot be modified through the interactive interface.

The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.

The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server can be directly connected with the access switch or directly connected with the terminal.

Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.

The node server is a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.

The metropolitan area server is a node which plays a centralized control function in the metropolitan area network and can control a node switch and a node server. The metropolitan area server can be directly connected with the node switch or directly connected with the node server.

Therefore, the whole video network is a network structure with layered centralized control, and the network controlled by the node server and the metropolitan area server can be in various structures such as tree, star and ring.

wherein, the packet (uplink data) coming from the downlink network interface module 301 enters the packet detection module 305; the packet detection module 305 detects whether the Destination Address (DA), the Source Address (SA), the packet type, and the packet length of the packet meet the requirements, and if so, allocates a corresponding stream identifier (stream-id) and enters the switching engine module 303, otherwise, discards the stream identifier; the packet (downstream data) coming from the upstream network interface module 302 enters the switching engine module 303; the incoming data packet of the CPU module 304 enters the switching engine module 303; the switching engine module 303 performs an operation of looking up the address table 306 on the incoming packet, thereby obtaining the direction information of the packet; if the packet entering the switching engine module 303 is from the downstream network interface to the upstream network interface, the packet is stored in the queue of the corresponding packet buffer 307 in association with the stream-id; if the queue of the packet buffer 307 is nearly full, it is discarded; if the packet entering the switching engine module 303 is not from the downlink network interface to the uplink network interface, the data packet is stored in the queue of the corresponding packet buffer 307 according to the guiding information of the packet; if the queue of the packet buffer 307 is nearly full, it is discarded.

The switching engine module 303 polls all packet buffer queues and may include two cases:

if the queue is from the downlink network interface to the uplink network interface, the following conditions are met for forwarding: 1) the port send buffer is not full; 2) the queued packet counter is greater than zero; 3) obtaining a token generated by a code rate control module;

if the queue is not from the downlink network interface to the uplink network interface, the following conditions are met for forwarding: 1) the port send buffer is not full; 2) the queue packet counter is greater than zero.

The rate control module 308 is configured by the CPU module 304, and generates tokens for packet buffer queues from all downstream network interfaces to upstream network interfaces at programmable intervals to control the rate of upstream forwarding.

The CPU module 304 is mainly responsible for protocol processing with the node server, configuration of the address table 306, and configuration of the code rate control module 308.

Wherein, the data packet coming from the downlink network interface module 401 enters the packet detection module 405; the packet detection module 405 detects whether the ethernet MAC DA, the ethernet MAC SA, the ethernet length or frame type, the video network destination address DA, the video network source address SA, the video network packet type, and the packet length of the packet meet the requirements, and if so, allocates a corresponding stream identifier (stream-id); then, the MAC deletion module 410 subtracts MAC DA, MAC SA, length or frame type (2byte) and enters the corresponding receiving buffer, otherwise, discards it;

the downlink network interface module 401 detects the sending buffer of the port, and if there is a packet, obtains the ethernet MAC DA of the corresponding terminal according to the destination address DA of the packet, adds the ethernet MAC DA of the terminal, the MAC SA of the ethernet protocol gateway, and the ethernet length or frame type, and sends the packet.

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.
