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 of a first step of a network access method of a service server according to an embodiment of the present invention is shown, and is applied to a video network, where the video network includes the service server and at least two core servers, and the method specifically includes the following steps:
step 501, determining whether the service server is connected with the core server in advance;
as an example, the video networking scheduling base service may be a product service of an application layer suite deployed in a traffic server, which may act as a gateway port for the traffic server. After the scheduling basic service of the video network is started, the service server can be in communication connection with at least one core server arranged in the video network through a video network protocol, and meanwhile, the service server can also be in communication connection with a platform arranged in the ethernet through an internet protocol, such as a monitoring management platform.
In specific implementation, the video network terminal can be in communication connection with the core server through a video network protocol, and after the video network scheduling basic service is started, the core server can be in communication with the service server through the video network protocol, so that the video network terminal can be in communication connection with a platform arranged in the Ethernet through the service server.
If a video network terminal deployed in a video network sends a data acquisition request to a core server, the core server can forward the data acquisition request to a service server, the service server can convert the data acquisition request based on a video network protocol into the data acquisition request based on an internet protocol and send the converted data acquisition request to a monitoring management platform deployed in an Ethernet, when the monitoring management platform receives the data acquisition request and responds, corresponding target data is sent to the service server, and then the service server can convert the target data based on the internet protocol into the target data based on the video network protocol and send the target data to the video network terminal through the core server.
In a specific implementation, the function of adding dual-computer hot standby to the video networking scheduling basic service can be realized by simultaneously sending network access instruction information to the service servers with the video networking scheduling basic service through at least one core server, and then selecting a target core server from each core server by the service servers according to the network access instruction information. When a problem occurs in the core server, which results in a disconnection of the communication connection between the core server and the service server, or the service server is first connected to the video network, it may be determined whether the service server is previously connected to the core server, so as to determine whether the service server has been connected to the video network, and step 502 or step 503 is performed.
Step 502, when the service server is not connected with the core server in advance, selecting one core server from the at least two core servers as a target core server according to the network access priority of the video networking protocol;
in the embodiment of the present invention, when the service server accesses the video network for the first time, that is, the service server is not connected to any core server in advance, one core server may be selected as a target core server from at least two core servers according to the network access priority of the video network protocol, and a communication connection with the target core server is established.
In the specific implementation, because the video network scheduling basic service in the service server is added with the function of dual-computer hot standby, the service server can select one core server from at least two core servers as a target core server, start the video network scheduling basic service in the service server, and establish communication connection with the video network of the target core server, so that the service server can serve as a communication medium between the video network and the Ethernet to realize data communication between the video network and the Ethernet.

s12, determining the priority of each network access sequence number, and taking the core server with the highest priority as a first target core server;
and S13, taking other core servers with lower priority than the first target core server as standby servers.
In the embodiment of the invention, in the video network, if each product service needs to perform communication connection or pass-through data packets, each product can be configured with a corresponding video network number, and the video network number needs to be registered in the core server in advance. When the registered video networking number is in communication connection, bridging forwarding can be performed through the core server, so that corresponding transparent transmission data is received and transmitted.
In a specific implementation, an internet of view number may be configured in the internet of view scheduling base service, and the internet of view number may be registered in the core server in advance. At least one core server can simultaneously send network access instruction information of the video network number aiming at the video network scheduling basic service to the service server. When the business server receives the network access instruction information, mac address data corresponding to the core server can be obtained according to the transparent transmission packet in the network access instruction information sent by different core servers, so that the network access instruction information is determined according to the mac address data, and whether the video network scheduling basic service in the business server is accessed to a certain core server is determined according to the network access instruction information.
In a specific implementation, the service server may simultaneously receive network access instruction information for the video network scheduling base service, which is sent by at least two core servers, then the video network scheduling base service may extract network access sequence numbers corresponding to the core servers from the network access instruction information, then determine priorities of the network access sequence numbers, respectively, then use the core server with the highest priority as a first target core server, and use other core servers with priorities lower than the first target core server as standby servers.
When the communication connection of the first target core server is interrupted, the communication connection of the standby server with the priority lower than that of the first target core server can be established, so that the function of dual-computer hot standby is added to the scheduling basic service of the video network, when one of the accessed core servers goes wrong and goes down, switching can be immediately carried out, a new target core server is selected from the standby server, the scheduling basic service of the video network is started, the service server is ensured to be accessed into the video network in real time, and the users of the video network can be ensured to obtain the data resources in the Ethernet in real time.
The network access instruction information sent by the core server includes a data packet of a video networking protocol hexadecimal, where the data packet includes a network access sequence number of the core server, such as 1, 2, 3, and the like, and the higher the value of the network access sequence number is, the higher the priority is.
In an example of the embodiment of the invention, assuming that a core server and a core server send network-accessing commands to the network-accessing number of the network-accessing scheduling basic service in a business server at the same time, the network-accessing scheduling basic service can obtain the network-accessing command information corresponding to the core server and the core server, and then the network-accessing scheduling basic service can determine the priority of the core server and the core server according to the network-accessing sequence number of the core server contained in the data packet of the network-accessing protocol hexadecimal in the network-accessing command information sent by the core server and the core server, when the network-accessing sequence number of the core server is greater than that of the core server, the priority of the core server is higher than that of the core server, the core server is taken as a target core server, the network-accessing scheduling basic service is taken as the core server, establishing communication connection between a business server and a core server I, and taking the core server II as a standby server; when the network access sequence number of the core server II is larger than that of the core server I, the priority of the core server II is higher than that of the core server I, the core server II is used as a target core server, communication connection between the business server and the core server II is established, the video network scheduling basic service is accessed to the core server II, and the core server I is used as a standby server. When the target core server goes wrong and goes down, switching can be immediately carried out, communication connection between the service server and the standby server is established, the service server is connected into the network video network, and therefore the fact that users of the network video network can acquire data in the Ethernet in real time and process the acquired Internet data in real time is guaranteed.
Step 503, when the service server is connected with the core server in advance, the previously connected core server is used as a target core server;
in the embodiment of the invention, when the communication connection between the service server and the core server is disconnected, namely the service server is connected with a certain core server in advance, the core server connected in advance can be used as the target core server, so that the communication connection with the target core server is reestablished by utilizing the dual-computer hot standby function of the video network scheduling basic service in the service server.
In a specific implementation, because the video network scheduling basic service in the service server is added with a dual-server hot standby function, the service server can select a core server connected in advance from at least two core servers (at least one core server which establishes communication connection once) as a target core server and establish communication connection with the video network of the target core server, so that the service server can serve as a communication intermediary between the video network and the ethernet network to realize data communication between the video network and the ethernet network.
In an alternative embodiment of the present invention, step 503 may include the following sub-steps:
s21, acquiring a configuration file aiming at the network access instruction information in the video networking scheduling basic service;
s22, extracting a network access sequence number for each core server from the configuration file;
s23, determining the priority of each network access sequence number, and using the core server with the highest priority as a second target core server;
and S24, taking other core servers with lower priority than the second target core server as standby servers.
In a specific implementation, the service server may receive network access instruction information sent by at least two core servers, where the network access instruction information may include network access information and non-network access information, and each network access instruction information received by the service server may include only one network access information and a plurality of non-network access information, a plurality of network access information and a plurality of non-network access information, and both the network access information and the non-network access information are network access information. The non-network-accessing information may be that the service server has not previously established a connection with the corresponding core server, and the network-accessing information may be that the service server has previously established a connection with the corresponding core server.
In the specific implementation, when the service server is connected with the core servers in advance, when the connection between the service server and the core servers is interrupted, network access instruction information aiming at the video network scheduling basic service and sent by at least two core servers can be received again, when each network access instruction information is network access information, a configuration file aiming at the network access instruction information in the video network scheduling basic service can be obtained, then a network access sequence number aiming at each core server can be extracted from the configuration file, then the priority of each network access sequence number is determined respectively, the core server with the highest priority is taken as a target core server, and other core servers with the priority lower than that of the target core server are taken as standby servers, so that the function of dual-computer hot standby is added to the video network scheduling basic service, when one of the networked core servers is down due to a problem, the switchover can be immediately made, a new target core server is selected from the standby servers, and the video network scheduling basic service is started.
The configuration file of the network access information of the core server is stored in the video network scheduling basic service in the service server, and the mac address data of the core server, the nodes (namely, the network access sequence numbers) related to the network access priority and the like are recorded in the configuration file.
In an example of the embodiment of the present invention, it is assumed that the current core server (i) and the core server (ii) simultaneously send network access instruction information to the network access number of the network access scheduling basic service in the service server, the network access instruction information corresponding to the core server (i) and the core server (ii) can be obtained by the network access scheduling basic service, when the network access instruction information corresponding to the core server (i) and the core server (ii) is the network access information, the network access scheduling basic service in the service server can determine the network access sequence number corresponding to the core server (i) and the core server (ii) according to the relevant node of the network access priority recorded in the configuration file, when the network access sequence number of the core server (i) is greater than that of the core server (ii), the core server (i) has a higher priority than that of the core server (ii), and is used as the target core server, accessing a video network scheduling basic service into a core server I, establishing communication connection between a business server and the core server I, and taking the core server II as a standby server; when the network access sequence number of the core server II is larger than that of the core server I, the priority of the core server II is higher than that of the core server I, the core server II is used as a target core server, the video network scheduling basic service is accessed to the core server II, the communication connection between the business server and the core server II is established, and the core server I is used as a standby server. When the target core server goes wrong and goes down, switching can be immediately carried out, communication connection between the service server and the standby server is established, the service server is connected into the network video network, and therefore the fact that users of the network video network can acquire data in the Ethernet in real time and process the acquired Internet data in real time is guaranteed.
In another optional embodiment of the present invention, step 503 may further include the following sub-steps:
and S26, when all the network access instruction information includes one piece of network access information, taking the core server corresponding to the network access information as a third target core server.

When the target core server goes wrong and goes down, switching can be immediately carried out, communication connection between the service server and the standby server is established, the service server is connected into the network video network, and therefore the fact that users of the network video network can acquire data in the Ethernet in real time and process the acquired Internet data in real time is guaranteed.
It should be noted that, in each example in the embodiment of the present invention, an example is performed by taking an example in which 2 core servers simultaneously send a network access instruction to a video network number of a video network scheduling basic service in a service server, and it can be understood that, when the number of the core servers is greater than 2, a network access manner of the service server is the same as a network access manner of the 2 core servers, and a specific process refers to the example and is not described herein again.

In a specific implementation, the video network is connected to an ethernet, the ethernet includes a monitoring management platform, and the video network may further include a video network terminal. The video network terminal can be a computer, a video television and the like. When the service server establishes communication connection with a target core server to realize network-in video network, a video network terminal can send a monitoring service data acquisition request to the target core server, the target core server can forward the monitoring service data acquisition request to the service server, the service server converts the monitoring service data acquisition request based on the video network protocol into a monitoring service data acquisition request based on the internet protocol and sends the monitoring service data acquisition request to a monitoring management platform, when the monitoring management platform receives the monitoring service data acquisition request, corresponding monitoring service data can be returned, the service server can convert the monitoring service data based on the internet protocol into the monitoring service data based on the video network protocol and sends the monitoring service data to the video network terminal, when the video network terminal receives the monitoring service data, the monitoring service data can be displayed or processed in real time, and the real-time performance of the monitoring data is guaranteed.
