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 data packets, and is 64 bytes if the data packet is a variety of protocol packets, and is 32+1024 or 1056 bytes if the data packet is a unicast data 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 characteristics of the video network, the information synchronization scheme provided by the embodiment of the invention follows the protocol of the video network, and can more efficiently synchronize the information of the monitoring resources.
Example one
The information synchronization method of the embodiment of the invention can be applied to the video network. The video network monitoring platform and the monitoring transfer server can be included in the video network, and the video network monitoring platform can be connected with the monitoring transfer server so as to add the monitoring transfer server. The video networking monitoring platform and the monitoring protocol conversion server can perform bidirectional interaction based on a video networking protocol.
The monitoring protocol server may be understood as a gateway, and is responsible for accessing external (e.g., on the internet) monitoring resources (which may also be described as monitoring devices) to the video network monitoring platform. The monitoring resources encode the collected monitoring videos based on the corresponding internet protocol, the monitoring protocol transfer server can acquire monitoring data based on the internet protocol after the monitoring resources are encoded, the monitoring protocol transfer server can convert the monitoring data based on the internet protocol into monitoring data based on the video networking protocol, and then the monitoring data is sent to a video networking monitoring platform, so that the monitoring resources on the internet are browsed and controlled in the video networking.
The monitoring protocol server may be connected to a plurality of monitoring resources, where the connection may be a direct connection. Therefore, the monitoring coordination server can record the information of the plurality of monitoring resources connected with the monitoring coordination server and can acquire the monitoring data of the plurality of monitoring resources connected with the monitoring coordination server.
The monitoring protocol server can also be connected with at least one third-party monitoring platform located in the internet. The third-party monitoring platform is required to be accessed to the monitoring protocol conversion server, firstly, the third-party monitoring platform is required to be registered on the monitoring protocol conversion server, and after the registration is successful, the third-party monitoring platform is accessed to the monitoring protocol conversion server. The monitoring co-transformation server and the third-party monitoring platform can perform bidirectional interaction based on an internet protocol. Each third party monitoring platform may be connected to a plurality of monitoring resources. Therefore, the monitoring co-transfer server can record the information of a plurality of monitoring resources connected through the accessed third-party monitoring platform and can acquire the monitoring data of the plurality of monitoring resources connected through the third-party monitoring platform, so that the video network monitoring platform and the third-party monitoring platform are in butt joint, and the monitoring resources in the video network and the internet are shared. The third-party monitoring platform can be a public security monitoring platform, a medical monitoring platform, and the like.
The video network monitoring platform can comprise a video network monitoring client, a video network monitoring server and a video network monitoring database. The video network monitoring client can be a Web end, and the video network monitoring server can be an Mserver. The video network monitoring client mainly provides interaction with a user; the video network monitoring server can be connected with the monitoring transfer server and is mainly used for providing interaction with the monitoring transfer server; the video network monitoring database can be connected with a video network monitoring server and is mainly used for storing relevant data such as information of monitoring resources and the like so as to be used for the video network monitoring server to perform operations such as inquiry, modification and the like.
In order to obtain the information of each monitoring resource, the video networking monitoring platform can obtain the information of each monitoring resource from the monitoring coordination server. However, in practical applications the status of the monitoring resources may change. For example, the status of the monitoring resource changes from online to offline due to disconnection of the network, or from offline to online due to reconnection of the network, etc. The video network monitoring platform may not know the state change condition of the monitoring resource in time, so that the information of the video network monitoring platform is inaccurate. In view of the above situation, the embodiments of the present invention provide a method for synchronizing information of monitoring resources in time, which is described in detail below.
Referring to fig. 5, a flowchart illustrating steps of an information synchronization method according to a first embodiment of the present invention is shown. The information synchronization method of the embodiment of the invention mainly relates to the synchronization of the information of the monitoring resources connected with a third-party monitoring platform, wherein the information synchronization method mainly relates to the state synchronization of the monitoring resources.
The information synchronization method of the embodiment of the invention can comprise the following steps:
step 501, after the monitoring protocol conversion server is restarted, judging whether a third-party monitoring platform accessed before restarting exists.
The monitoring protocol server may reboot for some reason. For example, the system is restarted after being upgraded, restarted after a system failure, restarted after being manually shut down, and the like.
In the embodiment of the present invention, the monitoring collaboration server may have access to one or more third party monitoring platforms before being restarted, or may not have access to the third party monitoring platforms. Therefore, after the monitoring protocol conversion server is restarted, whether a third-party monitoring platform accessed before the restart exists can be judged.
In one embodiment, the monitoring collaboration server has recorded therein information of a plurality of monitoring resources. The information of the monitoring resource may include at least an identifier (which may include a name) of the monitoring resource, a connected device (which may include an identifier of the monitoring coordination server, an identifier of the third-party monitoring platform), a status (which may include online, offline), a geographic location, and the like. Therefore, the monitoring co-transformation server can judge whether a third-party monitoring platform accessed before restarting exists according to the information of the monitoring resources recorded by the monitoring co-transformation server.
In a specific implementation, step 501 may include: the monitoring co-transformation server acquires the recorded information of the monitoring resources; the monitoring protocol conversion server judges whether a third-party monitoring platform exists in the connected equipment; if so, determining that the third-party monitoring platform accessed before restarting exists, namely the third-party monitoring platform existing in the connected equipment is the third-party monitoring platform accessed before restarting.
In another embodiment, after the monitoring collaboration server accesses a third-party monitoring platform, the monitoring collaboration server may also record information of the accessed third-party monitoring platform. The information of the third party monitoring platform may include at least an identification, a status (which may include online, offline), and the like of the third party monitoring platform. Therefore, the monitoring cooperation server can judge whether the accessed third-party monitoring platform exists before restarting according to the information of the third-party monitoring platform.
In a specific implementation, step 501 may include: the monitoring protocol conversion server judges whether the recorded information of the third-party monitoring platform exists or not; if so, determining that the accessed third-party monitoring platform before restarting exists, namely the third-party monitoring platform corresponding to the recorded information of the third-party monitoring platform exists, namely the accessed third-party monitoring platform before restarting exists.
Step 502, if the monitoring protocol conversion server determines that the third party monitoring platform exists, detecting whether the state of the accessed third party monitoring platform changes before the restart.
If the monitoring co-rotation server determines that there is no third-party monitoring platform accessed before restarting, the processing procedure of the third-party monitoring platform accessed before restarting in the embodiment of the present invention may not be executed, that is, the steps 502 to 504 are not executed.
If the monitoring protocol conversion server judges that the third-party monitoring platform accessed before restarting exists, the current state of the third-party monitoring platform accessed before restarting can be detected, and compared with the state before restarting of the monitoring protocol conversion server, whether the state changes or not can be detected.
In an embodiment, after accessing the monitoring co-transformation server, if the third-party monitoring platform is online, the third-party monitoring platform may send a heartbeat message (e.g., a heartbeat message) to the monitoring co-transformation server according to a set period. Therefore, the monitoring cooperation server can detect whether the state of the third-party monitoring platform which is accessed before restarting is changed or not according to the heartbeat message.
In a specific implementation, step 502 may include: the monitoring co-rotation server detects whether a heartbeat message sent by an accessed third-party monitoring platform before restarting is received in a set time period from the restart; if the monitoring protocol conversion server receives the request, determining that the current state of the accessed third-party monitoring platform before restarting is online; if not, determining that the current state of the accessed third-party monitoring platform before restarting is offline; and the monitoring co-transformation server compares whether the current state of the accessed third-party monitoring platform before the restart is consistent with the recorded historical state. If the state of the third-party monitoring platform is consistent with the state of the third-party monitoring platform, determining that the state of the accessed third-party monitoring platform is not changed before restarting; and if the state of the third-party monitoring platform is inconsistent with the state of the third-party monitoring platform, determining that the state of the third-party monitoring platform accessed before restarting is changed.
In addition, for the above-mentioned setting period and the specific value of the setting time period, a person skilled in the art may select any suitable value according to practical experience, and the embodiment of the present invention is not limited thereto. The set period and the set time period may be the same or different.
Step 503, if the monitoring coordination server detects that the change occurs, the recorded state of the monitoring resource connected to the previously accessed third-party monitoring platform is updated.
If the state of the third-party monitoring platform changes, the state of the monitoring resource connected with the third-party monitoring platform may also change. Therefore, after detecting that the state of the third-party monitoring platform accessed before restarting is changed, the monitoring coordination server can also update the recorded state of the monitoring resource connected with the third-party monitoring platform accessed before restarting.
In a specific implementation, step 503 may include:
a1, if the monitoring coordination server detects that the state of the third party monitoring platform accessed before the restart is changed from online to offline, the recorded state of the monitoring resource connected to the third party monitoring platform accessed before the restart is all updated to offline.
If the state of the third-party monitoring platform is changed from online to offline, the state of the third-party monitoring platform connecting all monitoring resources is also changed to offline. Therefore, in this case, the monitoring coordination server uniformly updates the states of the monitoring resources connected to the third-party monitoring platform that has been accessed before the restart to the offline state.
A2, if the monitoring coordination server detects that the state of the third-party monitoring platform accessed before the restart is changed from offline to online, the monitoring coordination server reacquires and records the state of the monitoring resource connected to the third-party monitoring platform accessed before the restart.
If the state of the third-party monitoring platform is changed from off-line to on-line, the state of the third-party monitoring platform connected with all monitoring resources is also changed to off-line after off-line. In this case, the monitoring coordination server will restart and record the status of the monitoring resource connected to the third-party monitoring platform that has been accessed before the restart.
For example, the monitoring co-rotation server may send an acquisition request to the third-party monitoring platform that has been accessed before the restart, so that the monitoring co-rotation server passively sends the current state of the connected monitoring resource to the monitoring co-rotation server after receiving the acquisition request. For another example, after the state of the accessed third-party monitoring platform before the restart is changed from offline to online, the accessed third-party monitoring platform before the restart may actively send the current state of the connected monitoring resource to the monitoring coordination server.
And step 504, the monitoring coordination server reports the updated state of the monitoring resource connected with the previously accessed third-party monitoring platform to the video network monitoring platform.
After the monitoring protocol conversion server updates the state of the monitoring resource connected with the accessed third-party monitoring platform before restarting, the updated state of the monitoring resource connected with the accessed third-party monitoring platform before restarting can be reported to the video network monitoring platform. The video networking monitoring platform can save the states of the monitoring resources so as to update the previously saved states of the corresponding monitoring resources.
In a specific implementation, the monitoring protocol conversion server may encapsulate, based on the video networking protocol, the updated state of the monitoring resource (which may also include information such as an identifier of the monitoring resource) connected to the third-party monitoring platform that has been accessed before the restart, as a video networking protocol data packet, and return the video networking protocol data packet to the video networking monitoring server. After receiving the encapsulated video networking protocol data packet, the video networking monitoring server can analyze the encapsulated video networking protocol data packet to obtain the state of the monitoring resource connected with the accessed third-party monitoring platform before the updated restart. And the video network monitoring server writes the updated state of the monitoring resources connected with the accessed third-party monitoring platform into the video network monitoring database, and can replace the original state of the monitoring resources so as to update the state of the monitoring resources.
The monitoring co-transformation server in the embodiment of the invention can update the state of the monitoring resource in time and report the updated state of the monitoring resource to the video network monitoring platform, so that the accuracy of monitoring resource information in the video network monitoring platform can be ensured; and the monitoring co-transformation server determines and updates the state of each monitoring resource connected with the monitoring co-transformation server according to the state of the third-party monitoring platform, so that detection and updating do not need to be performed on each monitoring resource, the workload can be reduced, the information synchronization efficiency can be improved, and the user experience can be improved.
In a preferred embodiment, after the monitoring protocol server is restarted, there may be a new third party monitoring platform that registers with the monitoring protocol server and thus accesses the monitoring protocol server. Therefore, the monitoring coordination server can also detect and process the situation.
In a specific implementation, the information synchronization method according to the embodiment of the present invention may further include:
b1, the monitoring protocol conversion server detects whether the third party monitoring platform which is not accessed before the restart is accessed after the restart.
For example, the monitoring co-rotation server may detect whether a new (i.e., not accessed before restarting) third-party monitoring platform is registered, and if the registration of a new third-party monitoring platform is successful, it indicates that the third-party monitoring platform is accessed to the monitoring co-rotation server.
B2, if the monitoring coordination server detects that the third party monitoring platform is accessed after the restart and is not accessed before the restart, the monitoring coordination server records the information of the monitoring resource connected to the third party monitoring platform accessed after the restart.
For example, if the monitoring coordination server detects that a new third-party monitoring platform is registered and the registration is successful, the monitoring coordination server may acquire and record information of monitoring resources connected to the third-party monitoring platform. Of course, the monitoring co-transformation server may also obtain and record information of the third-party monitoring platform, such as an identifier, a status, and the like of the third-party monitoring platform.
And B3, the monitoring co-transformation server reports the information of the monitoring resources connected with the third-party monitoring platform accessed after the restart to the video network monitoring platform.
The reporting process is substantially similar to the step 504, and specific reference may be made to the related description of the step 504, and the embodiment of the present invention is not discussed in detail herein.
The above-mentioned process of detecting and processing whether to access a new third-party monitoring platform after the monitoring co-rotation server is restarted may be executed in a loop after the monitoring co-rotation server determines that there is no third-party monitoring platform that has been accessed before the restart in step 502.
In a preferred embodiment, after the monitoring collaboration server is restarted, the state of the currently accessed third-party monitoring platform may also be changed. Therefore, the monitoring coordination server can also detect and process the situation.
In a specific implementation, the information synchronization method according to the embodiment of the present invention may further include:
c1, the monitoring coordination server detects whether the state of the currently accessed third party monitoring platform changes.
According to practical situations, the currently accessed third-party monitoring platform may include a third-party monitoring platform that has been accessed before the restart, and a third-party monitoring platform that is accessed after the restart.
As mentioned above, after the third-party monitoring platform accesses the monitoring co-rotation server, if the third-party monitoring platform is online, the third-party monitoring platform may send a heartbeat message to the monitoring co-rotation server according to a set period. Therefore, the monitoring cooperation server can detect whether the state of the currently accessed third-party monitoring platform changes or not according to the heartbeat message.
In a specific implementation, when receiving a heartbeat message sent by a currently accessed third-party monitoring platform, the monitoring coordination server may record the time when the heartbeat message is received, and record that the state is online. The monitoring protocol conversion server can detect whether the heartbeat message sent by the currently accessed third-party monitoring platform is received again within a second set time period from the receiving of the heartbeat message sent by the currently accessed third-party monitoring platform; if not, determining that the state of the currently accessed third-party monitoring platform is changed from online to offline; after the state of the currently accessed third-party monitoring platform is determined to be changed from online to offline, if the heartbeat message sent by the currently accessed third-party monitoring platform is received again, the state of the currently accessed third-party monitoring platform is determined to be changed from offline to online.
In addition, for the specific value of the second set time period, a person skilled in the art may select any suitable value according to practical experience, and the embodiment of the present invention is not limited thereto.
C2, if the monitoring coordination transfer server detects the change, it updates the recorded state of the monitoring resource connected to the currently accessed third-party monitoring platform.
Step C2 is substantially similar to step 503, and may be described with particular reference to step 503, and embodiments of the present invention will not be discussed in detail herein.
And C3, the monitoring coordination transfer server reports the updated state of the monitoring resource connected with the currently accessed third-party monitoring platform to the video network monitoring platform.
Step C3 is substantially similar to step 504 described above, and reference is made specifically to the description related to step 504 described above, and embodiments of the present invention will not be discussed in detail herein.
The above-mentioned process of detecting and processing the condition that the state of the currently accessed third party monitoring platform changes after the monitoring coordination server is restarted can be executed in a loop after the monitoring coordination server determines that there is no third party monitoring platform that has been accessed before the restart in step 502. Or after the above-mentioned process of detecting and processing whether to access the new third-party monitoring platform after the monitoring co-rotation server is restarted, the loop execution may be performed.
The embodiment of the invention solves the problem that the monitoring coordination server can not manage the state of the monitoring resource accessed by the third-party monitoring platform according to the state change of the third-party monitoring platform.
