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 data synchronization scheme provided by the embodiment of the invention follows the protocol of the video network, accesses the monitoring resources in the internet into the video network for processing, and has more comprehensive synchronized data and improved user experience.
The data 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 the video network monitoring server and is mainly used for storing relevant information of monitoring resources so as to enable the video network monitoring server to perform operations such as inquiry and modification.
Example one
Referring to fig. 5, a flowchart illustrating steps of a data synchronization method according to a first embodiment of the present invention is shown. The data synchronization method of the embodiment of the invention mainly relates to the synchronization of monitoring resources connected with a third-party monitoring platform.
The data synchronization method of the embodiment of the invention can comprise the following steps:
In practical applications, the monitoring resources connected to the third-party monitoring platform 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 third-party monitoring platform can store the information of the monitoring resources connected with the third-party monitoring platform. The third-party monitoring platform can detect the condition that the monitoring resource connected with the third-party monitoring platform changes, and can report the information of the changed monitoring resource to the monitoring transfer server after detecting that the monitoring resource connected with the third-party monitoring platform changes.
In the implementation, the third-party monitoring platform and the monitoring co-transformation server interact based on an internet protocol. Therefore, the third-party monitoring platform encapsulates the information of the changed monitoring resource based on the internet protocol to obtain the internet protocol data packet encapsulated with the information of the changed monitoring resource. And the third-party monitoring platform reports the information of the monitoring resources which are packaged based on the Internet protocol and change, namely the Internet protocol data packet, to the monitoring protocol conversion server through the Internet. For example, the third party monitoring platform may be a national standard (GB/T28181) platform, and the third party monitoring platform encapsulates information of the changed monitoring resource based on a national standard GB/T28181 protocol.
After receiving the information of the changed monitoring resource, which is encapsulated based on the internet protocol, once, that is, the internet protocol data packet, the monitoring protocol data packet is decapsulated and the like to obtain the information of the changed monitoring resource included therein.
In the embodiment of the invention, the third-party monitoring platform can store the lowest directory to which the monitoring resources connected with the third-party monitoring platform belong. The lowermost directory refers to the lowermost region to which the monitoring resource belongs. For example, if the complete directory to which a certain monitoring resource belongs is a beijing city-hai lake district-zhongguancun street, the beijing city is the top directory to which the monitoring resource belongs, and the zhongguancun street is the bottom directory to which the monitoring resource belongs. The information of the changed monitoring resource reported by the third-party monitoring platform may include information such as an identifier, a state, and a subordinate directory of the changed monitoring resource. The monitoring co-transformation server can obtain the complete directory to which the changed monitoring resource belongs according to the information of the changed monitoring resource.
In an alternative embodiment, step 502 may include: the monitoring co-transformation server queries the upper-level directory step by step according to the lowest-level directory to which the changed monitoring resource belongs until the highest-level directory to which the changed monitoring resource belongs is queried; and the monitoring co-transformation server connects the lowest-level directory with the inquired directories at all levels step by step to serve as the complete directory to which the changed monitoring resource belongs.
For example, if the lowest-level directory to which the changed monitoring resource belongs, which is included in the information of the changed monitoring resource received by the monitoring co-transfer server, is a customs street, the monitoring co-transfer server may query that the previous-level directory of the customs street is a hai lake area according to the customs street, and may query that the previous-level directory of the hai lake area is beijing, and that the beijing is the highest-level directory to which the changed monitoring resource belongs according to a dry point, so that the monitoring co-transfer server may determine that beijing, hai lake area, and customs street are complete directories to which the changed monitoring resource belongs.
After the monitoring co-transformation server obtains the complete directory to which the changed monitoring resource belongs, the information of the changed monitoring resource and the complete directory to which the changed monitoring resource belongs can be synchronized to the video network monitoring platform. Therefore, the complete directory to which the changed monitoring resource belongs is searched in the subsequent process, the method is simpler and more efficient, and the user experience is improved.
In the implementation, the monitoring protocol conversion server and the video networking monitoring platform interact based on a video networking protocol. Therefore, the monitoring protocol conversion server encapsulates the information of the changed monitoring resource and the complete directory to which the changed monitoring resource belongs based on the video networking protocol to obtain the video networking protocol data packet encapsulated with the information of the changed monitoring resource and the complete directory to which the changed monitoring resource belongs. The monitoring protocol conversion server synchronizes the information of the changed monitoring resources based on the video networking protocol encapsulation and the complete catalogue to which the changed monitoring resources belong, namely the video networking protocol data packet, to the video networking monitoring platform through the video networking.
Specifically, the monitoring cooperation server interacts with a video network monitoring server of a video network monitoring platform, and information of the changed monitoring resources based on the video network protocol package and a complete directory to which the changed monitoring resources belong are synchronized to the video network monitoring server through the video network. And the video network monitoring server stores the information of the changed monitoring resources based on the video network protocol package and the complete directory to which the changed monitoring resources belong to the video network monitoring database. The user can check the information of the changed monitoring resources and the complete catalog to which the changed monitoring resources belong on the video network monitoring client.
In the embodiment of the invention, the monitoring coordination server not only synchronizes the information of the changed monitoring resources to the video network monitoring platform, but also synchronizes the complete directory to which the changed monitoring resources belong to the video network monitoring platform, so that when a user wants to check the complete directory to which the changed monitoring resources belong, the video network monitoring platform can acquire the complete directory more simply, conveniently and quickly, and the user experience is improved. In addition, the embodiment of the invention can also realize that the monitoring resources in the Internet are accessed into the video network for processing, and the video network has higher speed and higher safety compared with the Internet.
Example two
Referring to fig. 6, a flowchart illustrating steps of a data synchronization method according to a second embodiment of the present invention is shown.
The data synchronization method of the embodiment of the invention can comprise the following steps:
In the embodiment of the invention, the information of the changed monitoring resources is reported to the monitoring transfer server for multiple times by the third-party monitoring platform in consideration of the possibility that the changed monitoring resources are multiple, and the information of the changed monitoring resources which are reported by the third-party monitoring platform through the internet and are packaged based on the internet protocol is received by the monitoring transfer server for multiple times.
Considering that if the monitoring protocol conversion server obtains the complete directory to which the changed monitoring resource belongs after receiving the information of the changed monitoring resource encapsulated based on the internet protocol each time, and synchronizes the information of the changed monitoring resource and the complete directory to which the changed monitoring resource belongs to the video network monitoring platform, the interaction times between the monitoring protocol conversion server and the video network monitoring platform are large, and the process is complex.
Therefore, in the embodiment of the present invention, after receiving information of a changed monitoring resource encapsulated based on an internet protocol once, the monitoring co-transformation server may first determine whether the third-party monitoring platform has reported the information of the changed monitoring resource. When the third-party monitoring platform has reported the information of the changed monitoring resource, executing step 603; and when the third-party monitoring platform does not report the information of the changed monitoring resource, the monitoring co-transfer server continues to receive the information of the changed monitoring resource which is reported by the third-party monitoring platform through the Internet and is packaged based on the Internet protocol.
In an alternative embodiment, step 602 may include: the monitoring protocol conversion server judges whether the time of the current time distance from the last time when the information of the monitoring resource which changes based on the internet protocol encapsulation is received exceeds a set threshold value; when the reported time exceeds a set threshold value, the reported time is judged to be over; and when the threshold value is not exceeded, judging that the report is not finished. For the specific value of the set threshold, a person skilled in the art may set any suitable value according to practical experience, for example, the set threshold may be set to 3000ms, 5000ms, and the like, which is not limited in this embodiment of the present invention.
And when the monitoring protocol conversion server judges that the information of the changed monitoring resources is reported by the third-party monitoring platform, uniformly acquiring the complete directory to which the changed monitoring resources belong. In this case, the changed monitoring resource is the monitoring resource corresponding to the received information of all the changed monitoring resources, and the monitoring coordination server obtains the complete directory to which the changed monitoring resource belongs for each changed monitoring resource. Of course, if the lowest directories to which the two changed monitoring resources belong are the same, the complete directories to which the two changed monitoring resources belong are also the same, so for the two changed monitoring resources, the complete directory to which the changed monitoring resources belong can be obtained only once as the complete directories to which the two changed monitoring resources belong.
For the specific process of acquiring the complete directory to which the changed monitoring resource belongs, reference is made to the related description of step 502 in the first embodiment, and the embodiment of the present invention is not discussed in detail herein.
And step 604, the monitoring cooperative conversion server packages the information of the changed monitoring resources and the complete directory to which the changed monitoring resources belong based on a video networking protocol, and synchronizes to the video networking monitoring platform through the video networking.
After acquiring the complete catalogue to which the monitoring resource belongs corresponding to the information of all the received changed monitoring resources, the monitoring protocol conversion server synchronizes the information of all the received changed monitoring resources and the complete catalogue to which all the changed monitoring resources belong to the video network monitoring platform.
For the specific process of synchronization, reference is made to the related description of step 503 in the first embodiment, and the embodiment of the present invention is not discussed in detail herein.
In the embodiment of the invention, the interaction times between the monitoring cooperative server and the video network monitoring platform can be reduced and the processing process is simplified in a batch processing mode.
EXAMPLE III
Referring to fig. 7, a flowchart illustrating steps of a data synchronization method according to a third embodiment of the present invention is shown.
The data synchronization method of the embodiment of the invention can comprise the following steps:
In the embodiment of the present invention, step 701 is the same as step 601 in the second embodiment, and specific reference may be made to the related description in the second embodiment.
In the embodiment of the present invention, step 702 is the same as step 602 in the second embodiment, and specific reference may be made to the related description of the second embodiment.
In the embodiment of the present invention, step 703 is the same as step 603 in the second embodiment, and specific reference may be made to the related description in the second embodiment.
Considering that the third-party monitoring platform and the monitoring Protocol-assisted transfer server interact based on the video networking Protocol, for example, the third-party monitoring platform uses a UDP (User Datagram Protocol) transmission mode to report information of the monitoring resource, which is encapsulated based on the internet Protocol and changes, to the monitoring Protocol-assisted transfer server. However, the reliability of the UDP transmission mode is relatively poor, and packet loss may occur, so that the monitoring coordination server may not completely receive information of the changed monitoring resource reported by the third-party monitoring platform. Moreover, when the monitoring resources of the third-party monitoring platform change, it is generally possible that all the monitoring resources in the entire complete directory change.
Therefore, in the embodiment of the present invention, after acquiring the complete directory to which the monitoring resource belongs corresponding to all the received information of the changed monitoring resource, the monitoring co-transformation server may send a synchronization request to the third-party monitoring platform. In the implementation, the monitoring protocol conversion server encapsulates the synchronous request based on the internet protocol to obtain the internet protocol data packet encapsulated with the synchronous request. And the monitoring protocol conversion server sends the synchronization request based on the internet protocol encapsulation, namely the internet protocol data packet to a third-party monitoring platform through the internet.
The synchronization request may include the complete directory to which all changed monitoring resources belong. And after receiving the synchronization request, the third-party monitoring platform carries out operations such as decapsulation and the like on the synchronization request to obtain a complete directory to which all the changed monitoring resources belong. And the third-party monitoring platform acquires information of all monitoring resources contained in the complete directory to which the changed monitoring resources belong, and returns the acquired information of all monitoring resources to the monitoring transfer server.
In the implementation, the third-party monitoring platform encapsulates the obtained information of all the monitoring resources based on the internet protocol to obtain an internet protocol data packet encapsulating the obtained information of all the monitoring resources. And the third-party monitoring platform returns all the acquired information of the monitoring resources, namely the internet protocol data packet, based on the internet protocol package to the monitoring protocol conversion server through the internet.
And after receiving the information of all the monitoring resources contained in the complete catalogue to which the changed monitoring resources encapsulated based on the internet protocol and returned by the third-party monitoring platform belong, the monitoring protocol conversion server carries out operations such as decapsulation and the like on the information of all the monitoring resources contained in the information.
The monitoring protocol conversion server compares the information of the changed monitoring resources reported by the third-party monitoring platform in step 701 with the information of all monitoring resources contained in the complete directory to which the changed monitoring resources belong, which is returned by the third-party monitoring platform in step 705, and selects information of monitoring resources containing more monitoring resources from the information.
And step 707, the monitoring protocol conversion server encapsulates the information of the selected monitoring resource and the complete directory to which the selected monitoring resource belongs based on the video networking protocol, and synchronizes to the video networking monitoring platform through the video networking.
And the monitoring cooperation server synchronizes the information of the selected monitoring resources and the complete directory to which the selected monitoring resources belong to the video network monitoring platform.
For the specific process of synchronization, reference is made to the related description of step 503 in the first embodiment, and the embodiment of the present invention is not discussed in detail herein.
In the embodiment of the invention, the monitoring co-transformation server further sends the synchronization request, so that the received information of the monitoring resource sent by the third-party monitoring platform is more complete, and the influence caused by packet loss is reduced.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.
