Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Referring to fig. 1, a flowchart illustrating steps of a method for displaying a directory of a monitoring resource according to an embodiment of the present invention is shown. The catalog display method for the monitoring resources can be applied to a monitoring system, the monitoring system can comprise a node server and a client, the node server can be used for managing the monitoring resources, the client can be used for displaying the catalog of the monitoring resources, one or more nodes are arranged in the catalog, the nodes are identification units of the monitoring resources on the client, and the client can be in communication connection with the node server.

The catalog display method for the monitoring resource can comprise the following steps.

Step 101, a client responds to a trigger operation of a user for a node of a directory, and generates a data acquisition instruction of the node.

In the embodiment of the present invention, after the client is started, the attribute information of one or more root nodes may be acquired from the node server, and then a directory only including the root nodes is generated according to the attribute information of the one or more root nodes. The attribute information of the root node may include at least a name and identification information. Besides, the attribute information of the root node may further include a number, a location, a status, and the like, and the content of the attribute information of the root node and the like are not particularly limited in the embodiment of the present invention. For example, after the client is started, an acquisition instruction of the attribute information of the root node is sent to the node server, the node server returns the attribute information of the root node to the client according to the acquisition instruction, and the client generates a directory only containing the monitoring resource of the root node by using the received attribute information of the root node. In practical application, the obtaining instruction of the root node attribute information sent by the client to the node server may include identification information of the client. And the node server determines the attribute information of the root node which can be displayed by the client according to the identification information of the client. It should be noted that the client may present the directory of the monitoring resources of all root nodes, or the client may present only a part of the directory of the monitoring resources of the root nodes. When the client can only display the directory of the monitoring resources of part of the root nodes, the node server can judge which directory of the monitoring resources of the root node or the root nodes can be specifically displayed by the client according to the identification information of the client, and further send the attribute information of the root nodes which can be displayed by the client to the client.

After the client displays the directory of the monitoring resources of one or more root nodes, the user can execute a trigger operation for a certain root node, and the client generates a data acquisition instruction for the root node in response to the trigger operation of the user. The data acquisition instruction may include identification information of the root node, and may further include identification information of the client.

In a preferred embodiment of the present invention, in addition to performing the trigger operation on the root node, the user may also perform the trigger operation on a child node of a next-level node of the root node, and the client may generate the data acquisition instruction of the child node in response to the trigger operation on the child node.

It is to be understood that the user may perform a trigger operation on any of the root nodes or the child nodes, and the client may generate a data acquisition instruction of any of the root nodes or the child nodes.

And 102, the client sends the data acquisition instruction to the node server so that the node server can acquire the monitoring resource data of the node according to the data acquisition instruction.

In the embodiment of the invention, the client sends the generated data acquisition instruction of the root node or the child node to the node server. The node server may obtain, according to the identification information of the root node or the identification information of the child node in the data acquisition instruction, identification information of one or more next-level nodes corresponding to the identification information of the root node or the identification information of the child node from a preset database by corresponding query, and then obtain, from the database, monitoring resource data corresponding to the identification information of the one or more next-level nodes by query. For example, the client sends the data acquisition instruction of the root node J1 to the node server. The node server queries the identification information of the next-level nodes J11, J12 and J13 of the root node J1 from the database according to the identification information of the root node J1, and further queries the database to obtain the monitoring resource data of the nodes J11, J12 and J13. For another example, the client sends the data acquisition instruction of the child node J21 to the node server. The node server queries the identification information of the next-level nodes J211, J212 and J213 of the child node J21 from the database according to the identification information of the child node J21, and further queries the database to obtain the monitoring resource data of the nodes J211, J212 and J213.

It should be noted that, the database may store a correspondence between the root node and the child node in advance, and may also store a correspondence between the root node and the next-level node, and a correspondence between the child node and the next-level node. In the embodiment of the present invention, a node displayed after the client is started may be referred to as a root node, a next-level node of the root node may be referred to as a child node, and a next-level node of the child node may also be referred to as a child node. Alternatively, nodes other than the root node may be referred to as child nodes.

In the embodiment of the present invention, after acquiring the monitoring resource data of a certain node, the node server may divide the monitoring resource data into a plurality of data packets according to the data amount of the monitoring resource data of the node, and compress each divided data packet and send the compressed data packet to the client. For example, if the data amount of the monitoring resource data of the node J1 exceeds the preset data amount threshold a, the node server divides the monitoring resource data of the node J1 into a plurality of data packets, and performs compression processing on each data packet, where the data amount of each compressed data packet may be b. Generally, directory structure information and monitoring resource information may be included in the data packet. For example, the data packet d01 includes directory structure information of the node J1 and the node J11, wherein the node J11 is a next-level node of the node J1, and the data packet d01 further includes monitoring resource information of the node J11, such as name, number, identification information, status, and the like of the monitoring device. The data packet d02 includes directory structure information of a node J1 and a node J12, wherein the node J12 is a next-level node of the node J1, and the data packet d02 further includes monitoring resource information of the node J12.

In a preferred embodiment of the present invention, the data packet may further include its number in the monitoring resource data, where the number may be a sequence number of the monitoring resource data divided into a plurality of data packets by the node server. In addition, the data packet may further include the total number of data packets obtained by the node server dividing the monitoring resource data to which the node server belongs.

And 103, the client receives the monitoring resource data from the node server and displays the monitoring resource data in the node.

In the embodiment of the invention, after the client receives the plurality of data packets compressed by the node server, the client can decompress the plurality of data packets to obtain the directory structure information and the monitoring resource information in each data packet. In practical applications, after receiving all data packets sent by the node server and addressed to a certain node, the client may perform a decompression operation on all data packets. Specifically, the client may determine whether all packets for a certain node are received according to the number of each packet and the total number of packets.

After the client decompresses the directory structure information and the monitoring resource information of each data packet, a corresponding node can be created according to the directory structure information obtained by decompression, and then the monitoring resource information is displayed in the corresponding node. For example, after the client receives the data packet d01 and the data packet d02, it is determined that all data packets for node J1 have been received according to the number in the data packet and the total number of data packets. The client creates nodes J11 and J12 according to the superior-inferior relation among the node J1, the node J11 and the node J12, wherein the nodes J11 and J12 are the next-level nodes of the node J1. Since node J1 is the root node, already existing in the client, there is no need to repeatedly create node J1. After the nodes J11 and J12 are created, the resource monitoring information for the node J11 may be exposed in the node J11 and the monitored resource information for the node J12 may be exposed in the node J12.

It should be noted that, if there is a respective next-level node in the node J11 and/or the node J12, a user is required to perform a trigger operation on the node J11 and/or the node J12, the client generates a data acquisition instruction for the node J11 and/or the node J12 in response to the trigger operation, the node server returns monitoring resource data for the node J11 and/or the node J12 to the client according to the data acquisition instruction for the node J11 and/or the node J12, and the client correspondingly displays the monitoring resource data for the node J11 and/or the node J12 in the node J11 and/or the node J12.

Based on the above description of the catalog display method for monitoring resources, a catalog display method for monitoring resources based on the internet of view is introduced below. As shown in fig. 2, the method for displaying a directory of monitoring resources based on a video network involves a desktop client, a video network core network and an MServer, wherein the desktop client is used for displaying the directory of the monitoring resources, the MServer is used for performing unified management on the monitoring resources, and the desktop client and the MServer are in communication connection through the video network core network. A user clicks a certain node on a desktop client, the desktop client generates a resource acquisition instruction aiming at the node, and then the resource acquisition instruction is sent to the MServer through the video network core network. The MServer reads the monitoring resource data from the database according to the resource acquisition instruction, divides and compresses the monitoring resource data to obtain a plurality of data packets, and returns the plurality of data packets to the desktop client through the video networking core network. After receiving all the data packets, the desktop client decompresses the received data packets to obtain monitoring resource information, and displays the monitoring resource information in the node.

In the embodiment of the invention, the user can execute the trigger operation aiming at the root node or the child node, and then the monitoring resource catalog of the root node or the child node is displayed on the client, so that the requirement of displaying the monitoring resource catalog according to the actual requirement of the user is realized.

In the embodiment of the present invention, a structural relationship between the root node and the child node may be set in advance in the database, and the structural relationship may be determined by a position relationship, a level relationship, and the like between the monitoring devices. The node server may search the database for the monitoring resource data of the node corresponding to the client according to the identification information of the client. For clients with different authorities, the monitoring resource directories of the nodes corresponding to the respective authorities can be displayed.

In the embodiment of the invention, after the node server queries the monitoring resource data of the node, the monitoring resource data can be divided into a plurality of data packets, and the plurality of data packets are compressed and then sent to the client. The method for transmitting the monitoring resource data by the node server in a subpackaging manner reduces the occupation of network bandwidth.

wherein, the packet (uplink data) coming from the downlink network interface module 601 enters the packet detection module 605; the packet detection module 605 detects whether the Destination Address (DA), the Source Address (SA), the type of the packet, and the length of the packet meet the requirements, if so, allocates a corresponding stream identifier (stream-id) and enters the switching engine module 603, otherwise, discards the stream identifier; the packet (downstream data) coming from the upstream network interface module 602 enters the switching engine module 603; the incoming data packet from the CPU module 604 enters the switching engine module 603; the switching engine module 603 performs an operation of looking up the address table 606 on the incoming packet, thereby obtaining the direction information of the packet; if the packet entering the switching engine module 603 is from the downstream network interface to the upstream network interface, the packet is stored in the queue of the corresponding packet buffer 607 in association with the stream-id; if the queue of the packet buffer 607 is close to full, it is discarded; if the packet entering the switching engine module 603 is not from the downlink network interface to the uplink network interface, the packet is stored in the queue of the corresponding packet buffer 607 according to the packet guiding information; if the queue of the packet buffer 607 is close to full, it is discarded.

The switching engine module 603 polls all packet buffer queues and may include two cases:

if the queue is from the downlink network interface to the uplink network interface, the following conditions are met for forwarding: 1) the port send buffer is not full; 2) the queued packet counter is greater than zero; 3) obtaining a token generated by a code rate control module;

if the queue is not from the downlink network interface to the uplink network interface, the following conditions are met for forwarding: 1) the port send buffer is not full; 2) the queue packet counter is greater than zero.

The rate control module 608 is configured by the CPU module 604 and generates tokens for packet buffer queues going to the upstream network interface from all downstream network interfaces at programmable intervals to control the rate of upstream forwarding.

The CPU module 604 is mainly responsible for protocol processing with the node server, configuration of the address table 606, and configuration of the code rate control module 608.

Wherein, the data packet coming from the downlink network interface module 701 enters the packet detection module 705; the packet detection module 705 detects whether the ethernet MAC DA, the ethernet MAC SA, the ethernet length or frame type, the video network destination address DA, the video network source address SA, the video network packet type and the packet length of the packet meet the requirements, and if so, allocates a corresponding stream identifier (stream-id); then, the MAC deleting module 710 subtracts MAC DA, MAC SA, length or frame type (2byte), and enters the corresponding receiving buffer, otherwise, discards;

the downlink network interface module 701 detects the sending buffer of the port, and if a packet exists, the downlink network interface module learns the ethernet MAC DA of the corresponding terminal according to the destination address DA of the packet, adds the ethernet MAC DA of the terminal, the MACSA of the ethernet coordination gateway, and the ethernet length or frame type, and sends the packet.

2. Video networking packet definition

2.1 Access network packet definition

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

label (R)

Payload

CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
