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.

Based on the above characteristics of the video network, one of the core concepts of the embodiments of the present invention is proposed, and a video network monitoring and scheduling platform (e.g., a PC end) sends a multi-path monitoring plan to a monitoring protocol conversion server through the video network protocol, following the protocol of the video network.

Referring to fig. 5, a flowchart illustrating steps of an embodiment of a monitoring method based on a video network according to the present invention is shown, where the method may be applied to a video network in which a video network protocol runs, and the video network includes a video network monitoring and scheduling platform, and specifically, the method may include the following steps:

step S501, acquiring parameters in a multi-path monitoring plan sent by the video networking monitoring and scheduling platform through a video networking protocol; the parameters comprise multipath monitoring resources and alarm threshold values;

in this embodiment of the application, a user may add a multi-path monitoring plan on a page through a video networking monitoring networking management scheduling platform, where parameters in the multi-path monitoring plan include multi-path monitoring resources and an alarm threshold, for example, the 10-path monitoring plan includes 10 camera (monitoring) resources and an alarm population threshold. And then parameters set by the multi-channel monitoring plan are issued to the monitoring protocol conversion server through the protocol of the video network 8F 8500C 1, and the monitoring protocol conversion server can acquire the parameters in the multi-channel monitoring plan sent by the video network monitoring network management scheduling platform through the protocol of the video network.

In a specific implementation, the video networking monitoring and networking management and scheduling platform may be a page presented by a PC, and the video networking monitoring and networking management and scheduling platform is provided with a function of adding and sending a multi-path monitoring plan, where the multi-path monitoring plan may be encrypted data or unencrypted data.

In practical application, a user may trigger the monitoring and networking management and scheduling platform of the video network to send the multi-path monitoring plan to the monitoring and co-rotating server in the video network through some operations in a menu (gtml) file, such as sending the multi-path monitoring plan, so as to request the monitoring and co-rotating server to call the multi-path monitoring code stream of the multi-path monitoring resource.

For example, a user may send a multi-path monitoring plan based on the video network to a monitoring protocol server of the video network through a video network monitoring network management scheduling platform, so that the monitoring protocol server calls a multi-path monitoring code stream of a multi-path monitoring resource.

In the video network, the video network monitoring network management scheduling platform can generate a multi-path monitoring plan through an 8e01 protocol, and the specification of the 8e01 protocol can be shown in the following table:

in the embodiment of the application, after receiving the multiple monitoring plans, the monitoring protocol server in the video network can also return response information to the monitoring network management and scheduling platform of the video network, which indicates that the multiple monitoring plans have been received.

In the video network, the monitoring protocol server may generate the response message through the 8e02 protocol.

In this practical application, the video network is a network with a centralized control function, and includes a main control server and a lower level network device, where the lower level network device includes a terminal, and one of the core concepts of the video network is that a table is configured for a downlink communication link of a current service by notifying a switching device by the main control server, and then a data packet is transmitted based on the configured table.

Namely, the communication method in the video network includes:

the main control server configures a downlink communication link of the current service;

and transmitting the data packet of the current service sent by the source terminal to a target terminal (such as a video networking monitoring and networking management scheduling platform) according to the downlink communication link.

In the embodiment of the present invention, configuring the downlink communication link of the current service includes: informing the switching equipment related to the downlink communication link of the current service to allocate a table;

further, transmitting according to the downlink communication link includes: the configured table is consulted, and the switching equipment transmits the received data packet through the corresponding port.

In particular implementations, the services include unicast communication services and multicast communication services. Namely, whether multicast communication or unicast communication, the core concept of the table matching-table can be adopted to realize communication in the video network.

As mentioned above, the video network includes an access network portion, in which the master server is a node server and the lower-level network devices include an access switch and a terminal.

For the unicast communication service in the access network, the step of configuring the downlink communication link of the current service by the master server may include the following steps:

in the substep S11, the main control server obtains downlink communication link information of the current service according to the service request protocol packet initiated by the source terminal, wherein the downlink communication link information includes downlink communication port information of the main control server and the access switch participating in the current service;

in the substep S12, the main control server sets a downlink port to which a packet of the current service is directed in a packet address table inside the main control server according to the downlink communication port information of the control server; sending a port configuration command to a corresponding access switch according to the downlink communication port information of the access switch;

in sub-step S13, the access switch sets the downstream port to which the packet of the current service is directed in its internal packet address table according to the port configuration command.

For multicast communication services (e.g., applications) in the access network, the step of the master server obtaining downlink communication link information of the current service may include the following sub-steps:

in the substep S21, the main control server obtains a service request protocol packet initiated by the target terminal and applying for the multicast communication service, wherein the service request protocol packet includes service type information, service content information and an access network address of the target terminal; wherein, the service content information comprises a service number;

substep S22, the master control server extracts the access network address of the source terminal in the preset content-address mapping table according to the service number;

in the substep of S23, the main control server obtains the multicast address corresponding to the source terminal and distributes the multicast address to the target terminal; and acquiring the communication link information of the current multicast service according to the service type information and the access network addresses of the source terminal and the target terminal.

After receiving the response information, the video networking monitoring networking management scheduling platform considers that the monitoring protocol conversion server has received and agrees to acquire the multi-channel monitoring plan.

Step S502, a preset stream adjusting protocol is adopted to adjust the multi-path monitoring code stream of the multi-path monitoring resources, and the multi-path monitoring code stream is sent to a code stream analysis Software Development Kit (SDK); the code stream analysis SDK is used for analyzing the number of people in the multi-path monitoring code stream;
