2. Vission networking data 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);
reserved bytes consist 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., 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 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 monitoring resource synchronization scheme provided by the embodiment of the invention follows the protocol of the video network, and ensures the accuracy of information and improves the user experience by synchronizing the monitoring resource information.
Example one
The monitoring resource synchronization method of the embodiment of the invention can be applied to the video network. In the monitoring system of the video network, the monitoring system can comprise a video network monitoring network management platform, a video network access server and a third-party platform, wherein the video network monitoring network management platform comprises a video network monitoring client, a video network monitoring server and a video network monitoring database. The video network access server is an inlet for accessing the monitoring resources into the video network, a large number of monitoring resources are butted through a third party platform, the monitoring resources are pushed to the video network access server by the third party platform, and then the monitoring resources on the video network access server are obtained by the video network monitoring server and are stored in a video network monitoring database of the video network monitoring management platform.
However, the monitoring resource in the third-party platform may change (for example, when the third-party platform is a public security platform, the change of the monitoring resource may be frequent, such as the increase and decrease of the number of the monitoring resource, the change of the running state of the monitoring resource, and the like), and then the monitoring resource on the video networking access server may also change, but the video networking monitoring management platform cannot acquire the change information of the monitoring resource in time, so that the situation that the information of the video networking monitoring management platform is inconsistent with the information of the monitoring resource of the video networking access server occurs. In order to solve the above problem, a monitoring resource synchronization method according to an embodiment of the present invention is provided.
Referring to fig. 5, a flowchart illustrating steps of a method for monitoring resource synchronization according to a first embodiment of the present invention is shown.

Example two
Referring to fig. 6, a flowchart illustrating steps of a method for monitoring resource synchronization according to a second embodiment of the present invention is shown. The method can be applied to video networking.
The monitoring resource synchronization method of the embodiment of the invention can comprise the following steps:
In a preferred embodiment, an operation page capable of providing setting information in the video network monitoring client is provided, a user can input related information on the operation page to set synchronous task information, the user can assign a unique identifier to the synchronous task information during setting, and the synchronous task information can be located according to the identifier. The operation page can also provide an increase button aiming at the synchronous task information, a user can trigger a synchronous task information increase instruction by clicking the increase button, and the video network monitoring client can store the set synchronous task information and the set synchronous task information identifier into the video network monitoring database after receiving the synchronous task information increase instruction. The synchronization task information may include information such as start time, time interval, synchronization mode, identifier of the access server of the video network, and the like. The synchronization mode may include full data synchronization, incremental data synchronization, and the like.
After the synchronous task information is stored by the video network monitoring client, a resource synchronization notification can be sent to the video network monitoring server, and the resource synchronization notification carries a synchronous task information identifier. And after receiving the resource synchronization notification, the video network monitoring server reads the synchronization task information from the video network monitoring database according to the resource synchronization notification. The method specifically comprises the following steps: the video network monitoring server extracts the synchronous task information identification from the resource synchronous notification, and can search the corresponding synchronous task information according to the synchronous task information identification; and the video network monitoring server reads the synchronous task information corresponding to the synchronous task information identification from the video network monitoring database.
And step 602, the video network monitoring server determines a target video network access server according to the synchronization task information and sends a resource synchronization instruction to the target video network access server.
The video network monitoring server can determine that the video network access server corresponding to the identifier is the target video network access server according to the video network access server identifier included in the synchronization task information, and then sends a resource synchronization instruction to the target video network access server. The number of the identifiers of the video network access servers included in the synchronization task information can be one or more, and thus the number of the target video network access servers can also be one or more.
In a preferred embodiment, the step 602 may include:
a1, after determining that the starting time is reached, the video network monitoring server generates a resource synchronization instruction carrying the synchronization mode.
The user may set a start time in the synchronization task information, where the start time is used to indicate when to start performing the resource synchronization process, for example, the start time may be a certain day, a certain time point in the day, and the like, which is not limited in this embodiment of the present invention. The video network monitoring server can judge whether the starting time is reached, if the starting time is not reached, the judgment is continued, and if the starting time is determined to be reached, a resource synchronization instruction carrying a synchronization mode is generated.
The synchronization mode comprises full data synchronization and incremental data synchronization. The full data synchronization may be information of all monitoring resources in the synchronization target video network access server, and the incremental data synchronization may be information of monitoring resources that change in the synchronization target video network access server. For different synchronization modes, the video network monitoring server can generate different resource synchronization instructions.
In a preferred embodiment, different video networking protocols may be set for different synchronization modes in the video networking, and therefore the step of generating the resource synchronization instruction carrying the synchronization mode may include: if the synchronization mode is full data synchronization, acquiring a first video networking protocol corresponding to the full data synchronization, and generating a resource synchronization instruction carrying the first video networking protocol; and if the synchronization mode is incremental data synchronization, acquiring a second video networking protocol corresponding to the incremental data synchronization, and generating a resource synchronization instruction carrying the second video networking protocol.
a2, the video network monitoring server sends the resource synchronization instruction to the target video network access server corresponding to the video network access server identification according to the time interval.
The user may also set a time interval in the synchronization task information, where the time interval is used to indicate how often the resource synchronization process is performed, for example, the time interval may be several days, several hours, and the like, and this is not limited in this embodiment of the present invention. The video network monitoring server can send a resource synchronization instruction to the target video network access server according to the time interval.
And the target video network access server receives the resource synchronization instruction, analyzes the resource synchronization instruction, acquires a video network protocol carried in the resource synchronization instruction, and acquires the synchronization mode according to the video network protocol. That is, if the resource synchronization instruction carries the first video networking protocol, it can be known that the synchronization mode is full data synchronization; if the resource synchronization instruction carries the second video networking protocol, it can be known that the synchronization mode is incremental data synchronization.
And the target video network access server generates corresponding monitoring resource data packets according to different synchronization modes aiming at the resource synchronization instruction. If the synchronization mode is full data synchronization, the target video network access server acquires the information of all accessed monitoring resources and generates a monitoring resource data packet comprising the information of all the monitoring resources; and if the synchronization mode is incremental data synchronization, the target video network access server acquires the information of the changed monitoring resources in the accessed monitoring resources and generates a monitoring resource data packet comprising the information of the changed monitoring resources. And the target video network access server returns the generated monitoring resource data packet to the video network monitoring server.
The video network monitoring server analyzes the monitoring resource data packet, for example, the monitoring resource data packet may be subjected to operations such as character string deserialization and object generation, extracts monitoring resource information included in the monitoring resource data packet, and stores the monitoring resource information to a video network monitoring database.
For the specific saving process, a person skilled in the art may perform relevant processing according to practical experience, and the embodiment of the present invention is not limited thereto. For example, the monitoring resource included in the analyzed monitoring resource information may be acquired during storage, and the information of the acquired monitoring resource stored in the database may be replaced with the analyzed monitoring resource information.
The video network monitoring client can read the updated monitoring resource information from the video network monitoring database, namely the monitoring resource information stored to the video network monitoring database by the video network monitoring server, and provides an update page, and the updated monitoring resource information is displayed in the update page. The user can more intuitively check the updated monitoring resource information, and the user experience is improved.
In a preferred embodiment, an operation page for stopping synchronization may be further provided in the video network client, where the operation page may show related content of the synchronization task information (such as a synchronization task information identifier, etc.), and a stop button is provided for the synchronization task information, a user may trigger a stop request by clicking the stop button, and after receiving the stop request, the video network client may send a stop synchronization notification to the video network monitoring server, where the stop synchronization notification may include the synchronization task information identifier.
And after receiving the synchronization stopping notification, the video network monitoring server determines the video network access server to be stopped according to the synchronization stopping notification, and stops sending the resource synchronization instruction to the video network access server to be stopped. In a specific implementation, the video network monitoring server may extract the synchronization task information identifier in the synchronization stop notification, acquire the video network access server identifier included in the synchronization task information corresponding to the synchronization task information identifier, determine that the video network access server corresponding to the acquired video network access server identifier is the video network access server to be stopped, and stop sending the resource synchronization instruction to the video network access server to be stopped. Therefore, the monitoring resources of the video network access server to be stopped are not continuously synchronized, and unnecessary synchronization process is avoided.
Preferably, after receiving the stop request, the video networking client may further send a stop synchronization notification to the video networking monitoring database, where the stop synchronization notification may include a synchronization task information identifier, and after receiving the stop synchronization notification, the video networking monitoring database deletes the synchronization task information corresponding to the synchronization task information identifier. Thereby saving the resources of the video networking monitoring database.
In the embodiment of the invention, the video networking monitoring and networking management platform can automatically and synchronously monitor resources, does not need manual update of operation and maintenance personnel, liberates a large amount of manpower, saves the manpower resources for video networking monitoring products and improves the customer satisfaction degree of the products.
