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.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for processing a service according to an embodiment of the present invention is shown, where the method is applied to a video network, where the video network includes a video network server and a video network terminal, and the video network server is deployed with a video network scheduling basic service, and the method specifically includes the following steps:

In a preferred embodiment of the present invention, a video networking monitoring, networking managing and scheduling system is deployed on the video networking server, and the method may further include the following steps:
the video networking monitoring and networking management scheduling system is locally configured with monitoring connection information aiming at different network environments, and the monitoring connection information corresponds to the monitoring service.
In the embodiment of the invention, the video networking server comprises a video networking monitoring and networking management and scheduling system and a video networking scheduling basic service, wherein the video networking monitoring and networking management and scheduling system integrates the computer screen image content of the service center service acceptance personnel and the video monitoring image resource of the service center by utilizing the video fusion technology and the service linkage advantages of the video networking. The monitoring personnel monitor the networked management and scheduling system through the video network, monitor the number of the masses in the comprehensive service center at any time, supervise the government affair handling operation of the business handling personnel and the like.
The video networking scheduling basic service is a console service program based on video networking communication, and is mainly used for supporting a bridge for video networking signaling transparent transmission between a video networking monitoring and networking management scheduling system and a terminal or a monitoring access server, for example, if a user wants to play monitoring at the terminal, the video networking monitoring and networking management scheduling system needs to send a video networking command for playing monitoring to the video networking scheduling basic service, the video networking scheduling basic service forwards the command to the terminal according to a video networking protocol, and the terminal executes the command.
In the embodiment of the invention, under the condition that a plurality of stages of switches are deployed in the same video networking server in the video networking environment, different network environments generated by the plurality of switches are configured through the video networking scheduling basic service, wherein the different network environments refer to IP addresses and ports of different network segments, and the video networking scheduling basic service establishes and enables the monitoring service aiming at the different network environments.
Wherein, the monitoring service is WebSocket monitoring service. The Websocket listening service is a network Protocol based on TCP (Transmission Control Protocol) used in an internet of view scheduling basic service program, and is used for realizing full duplex communication between a client (internet of view terminal) browser and a server and allowing the server to actively send a message to the client.
The WebSocket protocol used by the monitoring server in the embodiment of the invention is a persistent protocol, and the WebSocket connection allows full-duplex communication between the client and the server, so that any party can push data to the other end through the established connection. Here, the scheduling basic service of the video networking establishes a monitoring service based on the WebSocket technology, and the monitoring service mainly monitors an IP address and a port bound by a current program. After the monitoring service is successfully created, the client can send data to the server through the IP address and the port.
When a user wants to view video networking services such as monitoring, video conference and the like, the video networking terminal can send a service command to the video networking monitoring and managing and dispatching system through the monitoring service corresponding to the network environment to which the video networking terminal belongs, and then the service command is forwarded to the corresponding terminal through the video networking dispatching basic service.
Monitoring connection information monitored by the video networking scheduling basic service, namely WebSocket monitoring connection, is configured in a system module at the current stage of the video networking monitoring and networking management scheduling system, and WebSocket monitoring connection under the network environment of different video networking terminals is established and maintained in an account information module of the video networking monitoring and networking management scheduling system.
The function of adding the WebSocket monitoring connection is to send some commands such as playing monitoring or connecting terminals to the video network scheduling basic service through the scheduling system according to the configured WebSocket monitoring connection (namely the connection address) when a user accesses the video network monitoring and managing scheduling system through a browser of the video network terminal.
In a preferred embodiment of the present invention, the step 502 may include the steps of:
the video network terminal sends a service command to the video network monitoring and networking management scheduling system;
the video networking monitoring, networking, managing and scheduling system determines the network environment to which the video networking terminal belongs;
and the video networking monitoring and networking management scheduling system monitors connection information according to local configuration aiming at the network environment, and sends the service command to the video networking scheduling basic service through a monitoring service corresponding to the monitoring connection information.
In the specific implementation, when video networking services such as monitoring, video conferencing and the like are performed, firstly, a video networking terminal sends a service command to a video networking monitoring and networking management and scheduling system, the video networking monitoring and networking management and scheduling system determines a network environment to which the video networking terminal belongs after receiving the service command, and then WebSocket connection is configured according to the local configuration aiming at the network environment so as to send the service command to a video networking scheduling basic service through a monitoring service corresponding to the WebSocket connection.
In a preferred embodiment of the present invention, the step 503 may include the following steps:
the video networking dispatching basic service converts the service command into a video networking service command according to a video networking protocol;
the video networking scheduling basic service sends the video networking service command to a corresponding target terminal;
and the target terminal processes according to the video networking service command.
In a specific implementation, after receiving a service command sent by a video networking monitoring networking management scheduling system, a networking scheduling base service converts the service command into a video networking service command according to a video networking protocol (transparent transmission protocol), and then sends the video networking service command to a corresponding target terminal, and the target terminal performs corresponding processing based on the command, for example, if viewing monitoring, the corresponding monitoring terminal is called to obtain video data.
In the embodiment of the invention, the video networking dispatching basic service establishes corresponding monitoring services aiming at different network environments, therefore, a video networking terminal can send a business command to the video networking dispatching basic service through the monitoring services corresponding to the network environment, and the video networking dispatching basic service sends the business command to a corresponding target terminal to process the business command.
In order to make the embodiments of the present invention better understood by those skilled in the art, the following description will be made with specific examples. Referring to fig. 6, which is a schematic view of a monitoring service of a video networking scheduling base service according to the present invention, in a scenario that a multi-stage switch is deployed in the same server in a video networking environment, different network environments, i.e., IP addresses and ports of different network segments, generated by the multi-switch are configured by the video networking scheduling base service, and the video networking scheduling base service creates a WebSocket monitoring service (WebSocket network monitoring service) of different network segments. Of course, if there is only one network environment, only a single WebSocket listening service may be deployed.
The PC terminal accesses through a browser, a system module at the current level of the video networking monitoring and networking management and scheduling system deployed on a video networking server configures WebSocket monitoring connection monitored by a video networking scheduling basic service, and an account information module of the video networking monitoring and networking management and scheduling system establishes and maintains the WebSocket monitoring connection under network environments of different video networking terminals (accounts), so that services can be simultaneously performed in different network environments by using one set of video networking monitoring and networking management and scheduling system.
For example, when a user wants to implement a video networking service for monitoring, the client establishes a connection between the command and a video networking scheduling base service (the service includes the WebSocket monitoring service) through a WebSocket monitoring connection allocated to the video networking terminal on a video networking monitoring and scheduling management scheduling system, and issues the command to the video networking scheduling base service, the video networking scheduling base service analyzes the command completely and converts the command into a hexadecimal command packet recognized by the video networking according to a video networking protocol, then the video networking scheduling base service issues the command to a corresponding terminal, and the terminal receives the command and then calls to view related video monitoring data.
By applying the embodiment of the invention, when the multi-stage switch is deployed in the same server under the video networking environment, only one set of video networking dispatching basic service is arranged in the server, and the video networking dispatching basic service can monitor a plurality of IP addresses simultaneously by realizing the multi-network card monitoring technology, so that a terminal user can use the set of video networking dispatching basic service when the switch is under different network environments.
