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.

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 byte, 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 the types of different datagrams, 64 bytes if various protocol packets, 32+1024=1056 bytes if single-multicast data packets, and certainly not limited to the above 2 types;

the CRC consists of 4 bytes and its calculation method follows 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., 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 invention: a label to uniquely describe a metropolitan area network device.

In the present 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 there are 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 0x0001. 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 all passively executed, which is different from label allocation of MPLS, which 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 provided, in which the standby server detects whether the main cooperative server is in an offline state by sending an online confirmation message to the main cooperative server, and if the main cooperative server is in the offline state, the standby server is switched to a working state to provide a service in place of the main cooperative server.

Fig. 5 is a flowchart of steps of a server switching method provided by an embodiment of the present invention, where the method is applied to a standby server in a video network, and as shown in fig. 5, the method includes:

and step 501, sending an online confirmation message to the master collaboration server.

In the embodiment of the invention, the standby server can be a server which is connected with the main cooperative server in advance, so that the standby server can interact with the main cooperative server in the subsequent steps. Specifically, the configuration may be performed based on the internet protocol addresses and port numbers of the standby server and the primary protocol server, so that a connection is established between the standby server and the primary protocol server.

Further, in order to timely replace the main cooperative server to provide services for other terminals when the main cooperative server fails, in the embodiment of the present invention, the standby server may send an online confirmation message to the main cooperative server to confirm whether the main cooperative server is in an offline state.

Step 502, under the condition that the response message returned by the master cooperative server is not received, determining that the master cooperative server is in an off-line state.

In the embodiment of the present invention, if the primary coordination server is not in the offline state, a response message is returned to the standby server after receiving the online confirmation message sent by the standby server, and correspondingly, if the primary coordination server is in the offline state, the primary coordination server cannot return the response message to the standby server.

Step 503, switching to a working state; the main message number, the stored data and the configured program of the standby server are the same as those of the main cooperation server.

In the embodiment of the present invention, if the standby server determines that the main cooperative server is in an offline state, correspondingly, in order to ensure that the service provided by the main cooperative server is not interrupted, at this time, the standby server may be switched to a working state, that is, a program configured on the standby server is run, so as to take over the service provided by the main cooperative server.

Further, the primary message number is an identifier indicating to which server the message sent by the terminal is to be sent in the video network, for example, assuming that the primary message number contained in the message sent by the terminal is 001, the message is sent to the server with the primary message number 001, and assuming that the primary message number contained in the message sent by the terminal is 002, the message is sent to the server with the primary message number 002. Correspondingly, because the main message numbers of the standby server and the main cooperation server are the same, when the main cooperation server is in an off-line state and the standby server is in a working state, the message sent to the main cooperation server by the terminal can be directly sent to the standby server, and further, because the data and the configured program stored in the standby server are the same, the standby server can be switched to the working state to replace the main cooperation server to interact with other terminals so as to provide services for other terminals.

In summary, in the server switching method provided in the embodiment of the present invention, the standby server sends the online confirmation message to the main cooperative server, and determines that the main cooperative server is in the offline state when the response message returned by the main cooperative server is not received, and then switches to the working state. The main message number, the stored data and the configured program of the standby server are the same as those of the main cooperation server. Therefore, the standby server enters a working state when the main cooperative conversion server is offline, and can provide services instead of the main cooperative conversion server during the offline period of the main cooperative conversion server, so that the problem of service interruption caused by the fact that the main cooperative conversion server enters an offline state due to faults is solved.

Fig. 6 is a flowchart of steps of another server switching method provided in an embodiment of the present invention, where the method is applied to a master collaboration server in a video network, and as shown in fig. 6, the method includes:

and 601, receiving an online confirmation message sent by the standby server.

In the embodiment of the invention, the main cooperative conversion server can be connected with the standby server in advance, so that the standby server can send the online confirmation message to the main cooperative conversion server. Accordingly, the primary collaboration server may receive the online confirmation message sent by the backup server. The online confirmation message may be used to confirm whether the master collaboration server is in an offline state.

Step 602, if the primary coordination rotation server is in a working state, returning a response message to the standby server, so that the standby server confirms that the primary coordination rotation server is in an offline state and switches to the working state under the condition that the response message is not received; the main message number, the stored data and the configured program of the standby server are the same as those of the main cooperation server.

In the embodiment of the invention, the main cooperation server returns a response message to the standby server when in the working state, so that the standby server can indicate that the main cooperation server is not in the off-line state, correspondingly, if the main cooperation server is in the off-line state, the standby server cannot return the response message to the standby server after receiving the on-line confirmation message sent by the standby server, so that the standby server can confirm whether the main cooperation server is in the off-line state or not by whether receiving the response message or not, and can switch to the working state when the main cooperation server is in the off-line state, further, the standby server can replace the main cooperation server to interact with other terminals by switching to the working state, and provides services consistent with the services provided by the main cooperation server for other terminals.

In summary, in another server switching method provided in the embodiments of the present invention, the primary coordination server may receive an online confirmation message sent by the standby server, and if the primary coordination server is in the working state, return a response message to the standby server, so that the standby server confirms that the primary coordination server is in the offline state under the condition that the response message is not received, and switch to the working state, where a primary message number, stored data, and a configured program of the standby server are the same as a primary message number, stored data, and a configured program of the primary coordination server. Therefore, the main cooperation server provides a basis for confirming whether the standby server is in the offline state or not by sending the response message, so that the standby server can timely enter the working state when the main cooperation server is in the offline state, the service is provided by replacing the main cooperation server during the offline state of the main cooperation server, and the problem of service interruption caused by the fact that the main cooperation server enters the offline state due to faults is solved.

Fig. 7 is an interaction flowchart of another server switching method provided in an embodiment of the present invention, where the method is applied in a video network, and as shown in fig. 7, the method includes:

and 701, the standby server sends an online confirmation message to the main transfer server.

In this step, the standby server may continuously send heartbeat confirmation messages to the main corotation server at a preset time interval, where the preset time interval may be preset according to an actual requirement, for example, the preset time interval may be 10 seconds, that is, the standby server may contact and send heartbeat confirmation messages to the main corotation server every 10 seconds, for example, the standby server may send a heartbeat confirmation message at 1 minute 10 seconds, send a heartbeat confirmation message at 1 minute 20 seconds, send a heartbeat confirmation message at 1 minute 30 seconds, and so on.

Step 702, the primary coordination and transformation server receives an online confirmation message sent by the standby server.

Accordingly, the master auxiliary rotation server may receive heartbeat confirmation messages continuously sent by the standby server to the master auxiliary rotation server at preset time intervals.

And 703, if the main cooperative transmission server is in a working state, the main cooperative transmission server returns a response message to the standby server.

In this step, if the master collaboration server is in a working state, the master collaboration server may return a confirmation message for each heartbeat confirmation message that is continuously sent, so as to indicate that the master collaboration server is not in an offline state.

Step 704, the standby server determines that the primary cooperative server is in an offline state when not receiving the response message returned by the primary cooperative server.

In an actual application scenario, the master cooperative rotation server may have a situation that a response message is not successfully returned to the standby server due to an error in message transmission, and at this time, if a response message returned by the master cooperative rotation server for a certain heartbeat acknowledgment message is not directly received, it is determined that the master cooperative rotation server is in an offline state, and a problem of misjudgment may occur. Therefore, this step can be realized by the following substep (1):

substep (1): if the standby server does not receive a response message returned by the main cooperation server to the N heartbeat confirmation messages, the main cooperation server is confirmed to be in an off-line state; and the response messages returned to the N heartbeat confirmation messages are continuously sent by the main protocol conversion server.

Specifically, N may be an integer not less than 2, and a specific value of N may be preset according to actual conditions, for example, N may be 3. In the embodiment of the invention, when the main cooperative rotation server does not return response messages to a plurality of continuous heartbeat confirmation messages, the main cooperative rotation server is determined to be in an off-line state, so that the possibility of misjudgment can be reduced, and the accuracy of determination operation can be improved.

Step 705, the standby server switches to a working state.

Specifically, the implementation manner of this step may refer to step 503, which is not described herein again in this embodiment of the present invention.

Further, after the standby server is switched to the operating state, the standby server needs to provide a service based on the data and the configured program stored in the standby server instead of the main transfer server, and in an actual application scenario, the data and the configured program stored in the main transfer server are often changed. The specific standby server can update the stored data through the following substeps (1) to (2):

substep (1): and when the times of receiving the response message by the standby server reach a first preset time, acquiring the data stored on the main cooperative conversion server.

In this step, the first preset number of times may be set according to an actual requirement, for example, the first preset number of times may be 20, and the first preset number of times may also be 30, which is not limited in this embodiment of the present invention, and of course, in another optional embodiment of the present invention, a time interval may also be used as a standard for updating data, for example, data stored in the main transfer server may be obtained once every 7 days to update data.

Further, the standby server may transmit a data acquisition request to the primary cooperative server based on a connection channel with the primary cooperative server, and accordingly, the primary cooperative server may transmit the stored data to the standby server after receiving the data acquisition request.

Substep (2): and the standby server performs synchronous updating operation on the data stored on the standby server based on the data stored on the main cooperative conversion server so as to enable the data stored on the standby server to be consistent with the data stored on the main cooperative conversion server.

In this step, the standby server may compare the acquired data with data stored in itself one by one, store data that is not stored in the standby server in the acquired data to the standby server, and delete data that is not stored in the standby server in the acquired data, so that the standby server and the main transfer server store the same data.

In the embodiment of the invention, the synchronous updating operation is carried out by acquiring all the data stored in the main transfer server and the auxiliary transfer server, so that the consistency of the data stored in the standby server and the data stored in the main transfer server can be ensured after the synchronous updating operation is carried out based on the data. It should be noted that, in an actual application scenario, in order to reduce the amount of data to be transmitted, the primary coordination server may also transmit the changed data to the standby server, and the standby server performs a synchronous update operation on the stored data only according to the changed data, which is not limited in this embodiment of the present invention.

Further, the standby server may implement the procedure of updating the configuration through the following substeps (3) to (6):

substep (3): and when the number of times of executing the synchronous updating operation reaches a second preset number of times, acquiring the program version number of the main corotation server.

In this step, the second preset number may be set according to an actual requirement, for example, the second preset number may be 10, and the second preset number may also be 15, which is not limited in this embodiment of the present invention, and in another optional embodiment of the present invention, a time interval may also be used as a standard for updating data, for example, the program version number of the master rotation server may be obtained once every 15 days, so as to perform program updating.

Further, the standby server may send a version number acquisition request to the primary cooperative server based on a connection channel with the primary cooperative server, and accordingly, the primary cooperative server may send the version number of the currently running program to the standby server after receiving the version number acquisition request.

Substep (4): and if the program version number of the main cooperative rotation server is not consistent with the degree version number of the standby server, sending a program upgrading instruction to the main cooperative rotation server.

In an actual application scenario, version numbers of programs of different versions are not used, and after a program configured on the main cooperative rotation server is updated each time, a program version number on the main cooperative rotation server correspondingly changes, so that if the program version number of the main cooperative rotation server is consistent with the degree version number of the standby server, it can be considered that the program configured on the standby server is the same as the program configured on the main cooperative rotation server, otherwise, if the program version number of the main cooperative rotation server is inconsistent with the degree version number of the standby server, it can be considered that the program configured on the standby server is different from the program configured on the main cooperative rotation server, at this time, a program upgrade instruction can be sent to the main cooperative rotation server, where the program upgrade instruction can be used to instruct the main cooperative rotation server to send an installation package of a currently configured program to the standby server.

Substep (5): and receiving the installation package sent by the main cooperation server.

In the embodiment of the present invention, after receiving the program upgrade instruction, the primary coordination server may send the installation package of the currently configured program to the standby server, and accordingly, the standby server may receive the installation package, so as to upgrade the program configured on the standby server.

Substep (6): and updating the version of the program configured on the standby server based on the installation package.

In this step, the standby server may parse the installation package, and then upgrade the currently configured program on the standby server by using the installation file in the parsed installation package, thereby ensuring that the program configured on the standby server is consistent with the program configured on the main cooperative server. It should be noted that, after upgrading the currently configured program, the standby server may be restarted in order to ensure that the upgrading operation is valid, and accordingly, after being restarted, the standby server may enter a standby state, that is, enter a state of detecting whether the main cooperative rotation server is in an offline state, and switch to an operating state when the main cooperative rotation server is in the offline state.

In the embodiment of the invention, the data stored in the standby server and the configured program are synchronously updated, so that the standby server can normally provide services for other terminals when replacing the main cooperation server to provide services, and the service quality is ensured.

Step 706, the standby server sends a fault reminding message to a user to remind the user to maintain the main cooperative server, so that the main cooperative server enters an online state.

In this step, the fault reminding information may be used to indicate that the main turning server fails, specifically, the standby server may send the fault reminding information to a preset user operation platform based on a preset data center server, for example, an Mserver server, so as to show that the main turning server fails to work to a user through the user operation platform, and of course, the standby server may also directly send the fault reminding information to an electronic device of the user, for example, a mobile phone. Furthermore, after the user receives the fault reminding information and knows that the main cooperative server fails, the user can maintain and restart the main cooperative server so that the main cooperative server enters an online state and can be put into use again.

It should be noted that, in the embodiment of the present invention, the execution sequence of the above steps is not unique, for example, step 706 may be placed after step 704 and before step 705, that is, the standby server may send the fault notification information to the user first after determining that the main coordination server is in the offline state, so that the main coordination server can be maintained in time, and then switch to the working state, and certainly, step 706 is placed after step 705, that is, after determining that the main coordination server is in the offline state, the standby server will switch to the working state first, and then send the fault notification information to the user, so that the main coordination server can be replaced to the fastest extent, and then the time for service interruption provided by the main coordination server is reduced to the greatest extent, and the service efficiency is ensured.

And 707, after the main coordination server enters an online state, acquiring data stored in the standby server.

Accordingly, in this step, the master cooperative conversion server may obtain the data stored on the standby server after entering the online state. Specifically, the main cooperative server may send a data acquisition request to the standby server, and accordingly, the standby server may send the stored data to the main cooperative server after receiving the data acquisition request.

Step 708, the primary coordination server performs a synchronous update operation on the data stored in the primary coordination server based on the data stored in the standby server.

Specifically, an implementation manner of the synchronous update operation performed by the primary and secondary rotation servers based on the acquired data is the same as that of the synchronous update operation performed by the standby server based on the acquired data in the sub-step (2), and reference may be made to the sub-step (2), which is not described herein again in the embodiment of the present invention. In the embodiment of the invention, the data stored in the main cooperative conversion server is synchronously updated, so that the main cooperative conversion server can normally provide service for other terminals after entering the working state again, and the service quality is ensured.

Step 709, after the primary coordination server completes the synchronous updating operation, sending a standby instruction to the standby server.

In this step, since the primary and backup servers have the same primary message number, if both are in a working state at the same time, when the terminal sends a message to the primary and backup servers based on the primary message number, the message may be repeatedly responded, and thus a problem of message processing confusion occurs.

Step 710, the main coordination server switches to a working state after the standby server enters a standby state.

In this step, the master cooperative transmission server may implement switching to the working state by running a program configured on the master cooperative transmission server. It should be noted that, in an actual application scenario, generally, the program configured on the standby server is not updated, and therefore, in the embodiment of the present invention, after the main transfer server enters the online state, the data on the main transfer server may be updated only before entering the working state, and of course, in another optional embodiment of the present invention, after the main transfer server enters the online state, the program configured on the main transfer server may be updated synchronously by interacting with the standby server before entering the working state, so as to ensure that the main transfer server and the standby server are consistent, which is not limited in the embodiment of the present invention.

In summary, in another server switching method provided in the embodiments of the present invention, the standby server sends an online confirmation message to the main cooperative server, the main cooperative server returns a response message in response to the received online confirmation message, and the standby server determines that the main cooperative server is in an offline state when the response message returned by the main cooperative server is not received, and then switches to the working state. The main message number, the stored data and the configured program of the standby server are the same as those of the main cooperation server. Therefore, the standby server enters a working state when the main cooperative conversion server is offline, and can provide services instead of the main cooperative conversion server during the offline period of the main cooperative conversion server, so that the problem of service interruption caused by the fact that the main cooperative conversion server enters an offline state due to faults is solved.
