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.
The processing scheme of the monitoring data provided by the embodiment of the invention can be applied to a cross-network flow regulation request scene of the monitoring data. For example, a monitoring client in a first network needs to retrieve monitoring data in a second network. When receiving a monitoring request instruction of a monitoring client, a first monitoring server in a first network locally inquires whether a target monitoring channel of target monitoring data exists, and if so, sends related information of the existing target monitoring channel to the monitoring client; if the monitoring request instruction does not exist, the monitoring request instruction is forwarded to a second monitoring server of a second network, the second monitoring server establishes a target monitoring channel according to the monitoring request instruction, relevant information of the target monitoring channel is returned to the first monitoring server, and the first monitoring server sends the relevant information of the target monitoring channel returned by the second monitoring server to the monitoring client.
Referring to fig. 1, a flowchart illustrating steps of a method for processing monitoring data according to an embodiment of the present invention is shown, where the method may be applied to a first monitoring server, where the first monitoring server is located in a first network, and the first network may further include a monitoring client communicatively connected to the first monitoring server in addition to the first monitoring server. The method specifically comprises the following steps:
In the embodiment of the present invention, the monitoring client may determine the target monitoring data in response to a monitoring request operation of the user for the target monitoring terminal in the monitoring list. The target monitoring data can be audio and video data collected by a target monitoring terminal.
In a preferred embodiment of the present invention, the first network may further include a monitoring terminal management server communicatively connected to the monitoring client. When acquiring the monitoring request information of the target monitoring data, the monitoring client may determine unique terminal identification information of the target monitoring terminal in response to a monitoring request operation of a user for the target monitoring terminal, and send the terminal identification information to the monitoring terminal management server. The monitoring terminal management server may obtain, in a pre-stored information list of each monitoring terminal, a number of a coordination server corresponding to the target monitoring terminal and a channel number of the target monitoring terminal in the corresponding coordination server by using the terminal identification information. Therefore, the first monitoring server may generate the monitoring request information according to the number of the cooperative server corresponding to the target monitoring terminal and the channel number of the target monitoring terminal in the corresponding cooperative server. Or, it may be considered that the monitoring request information includes a number of a protocol server corresponding to the target monitoring terminal, and a channel number of the target monitoring terminal in the corresponding protocol server. The information list pre-stored in the monitoring terminal management server may include terminal identification information, terminal position information, terminal configuration information, a number of an affiliated coordination server, a channel number of the monitoring terminal on the affiliated coordination server, and the like of each monitoring terminal.
It should be noted that each monitoring terminal may access to the second network through a corresponding coordination server, that is, each monitoring terminal and the coordination server corresponding to each monitoring terminal are located in the second network. The cooperative conversion server mainly has the function of accessing the monitoring equipment to the second network, and the configuration and the position of the cooperative conversion server, the configuration and the number of the accessed monitoring equipment and the like are not particularly limited in the embodiment of the invention.
And 102, inquiring whether a target monitoring channel of target monitoring data exists according to the monitoring request information.
In the embodiment of the present invention, the first monitoring server may perform communication connection with the second monitoring server in the second network according to a preset private protocol. The above-mentioned private protocol may be understood as a service logic in actual operation, and the content, rule, and the like of the private protocol are not specifically limited in the embodiment of the present invention. The second monitoring server in the second network may manage the monitoring data of the monitoring terminals accessed to the second network, for example, the second monitoring server may be communicatively connected to one or more collaboration servers, each collaboration server may access a respective monitoring terminal. The second monitoring server can establish a monitoring channel with the monitoring terminal through the cooperation server, and then obtain the monitoring data. And, manage the relevant information of the monitoring channel established. In practical applications, the information related to monitoring the channel may include, but is not limited to: channel identification information, channel setup time information, monitoring terminal information, and the like. The monitoring terminal information may include a number of a protocol server to which the monitoring terminal belongs, a channel number of the monitoring terminal on the protocol server to which the monitoring terminal belongs, and the like.
If the monitoring client in the first network requests to perform monitoring operation on the target monitoring data in the second network, the second monitoring server in the second network may transmit the relevant information of the target monitoring channel of the target monitoring terminal of the target monitoring data to the first monitoring server in the first network. The first monitoring server may locally log information about each monitoring channel received from a second monitoring server in the second network. When the first monitoring server receives the monitoring request information of the monitoring client, whether a target monitoring channel corresponding to the monitoring request information exists or not can be firstly inquired in the related information of the monitoring channel recorded locally.
In a preferred embodiment of the present invention, when the first monitoring server queries whether a target monitoring channel of target monitoring data exists locally according to the monitoring request information, the first monitoring server may first query whether a first monitoring channel corresponding to a number of a coordination server corresponding to the target monitoring data exists in related information of a locally recorded monitoring channel; and if the first monitoring channel exists, inquiring whether a second monitoring channel corresponding to the channel number of the target monitoring data on the protocol conversion server exists in the first monitoring channel. And if the second monitoring channel exists, taking the second monitoring channel as a target monitoring channel.
If the first monitoring server locally has a target monitoring channel, executing step 103; if the first monitoring server does not have the target monitoring channel locally, step 104 is executed.
And 103, returning the relevant information of the target monitoring channel to the monitoring client so that the monitoring client performs monitoring operation on the target monitoring data by using the relevant information of the target monitoring channel.
In the embodiment of the present invention, the first monitoring server returns the relevant information of the locally existing target monitoring channel to the monitoring client, and the monitoring client may perform a monitoring operation on the target monitoring data based on the relevant information of the target monitoring channel. In practical application, the monitoring client can access the target monitoring channel by using the related information of the target monitoring channel, and the first monitoring server transmits the target monitoring data to the monitoring client through the target monitoring channel. When transmitting the target monitoring data, the first monitoring server may transmit the target monitoring data to the monitoring client according to a real-time transmission protocol. The real-time transport protocol provides an end-to-end delivery service with real-time characteristics for target monitoring data, such as interactive video, audio or analog data under multicast or unicast network services.
And 104, forwarding the monitoring request information to the second monitoring server so that the second monitoring server establishes a target monitoring channel according to the monitoring request information, and returning the related information of the target monitoring channel to the first monitoring server.
In the embodiment of the present invention, if the first monitoring server does not locally exist the relevant information of the target monitoring channel, the monitoring request information of the monitoring client is transmitted to the second monitoring server through the private protocol with the second monitoring server. And the second monitoring server sends a flow regulation request of the monitoring data in the video internet to the corresponding protocol conversion server according to the number of the protocol conversion server in the monitoring request information. And the corresponding coordination server returns the target monitoring data to the second monitoring server according to the received flow regulation request. And the second monitoring server returns the relevant information of the target monitoring channel and the target monitoring data to the first monitoring server.
After receiving the relevant information of the target monitoring channel of the second monitoring server, the first monitoring server may return the relevant information of the target monitoring channel to the monitoring client, and return the target monitoring data to the monitoring client through the target monitoring channel.
In a preferred embodiment of the present invention, after the monitoring client sends the monitoring request message to the first monitoring server, if the monitoring client does not need to perform monitoring operation on the target monitoring data, the monitoring client may send monitoring shutdown information to the first monitoring server. The first monitoring server receives the monitoring closing information of the monitoring client and can stop returning the target monitoring data to the monitoring client. And the first monitoring server can also inquire whether other monitoring clients are utilizing the target monitoring channel to monitor the target monitoring data according to the monitoring closing information. If other monitoring clients are monitoring the target monitoring data by using the target monitoring channel, no processing is performed; and if no other monitoring client side is monitoring the target monitoring data by using the target monitoring channel, forwarding monitoring closing information to the second monitoring server. The second monitoring server may stop returning the target monitoring data to the first monitoring server according to the monitoring closing information, and close the target monitoring channel.
When querying whether other monitoring clients are utilizing the target monitoring channel to monitor the target monitoring data, the first monitoring server may query whether other monitoring clients are utilizing the target monitoring channel according to a utilization list of the target monitoring channel recorded in advance. The utilization list may record related information of the target monitoring channel, and a start time and an end time of the target monitoring channel for the monitoring client. The start time represents the time when the monitoring client starts to monitor the target monitoring data by using the target monitoring channel, and the end time represents the time when the monitoring client ends to monitor the target monitoring data by using the target monitoring channel. If the end time of the target monitoring channel recorded in the utilization list for the monitoring client is empty, it indicates that the target monitoring channel is still utilized by the monitoring client.
It should be noted that the first network may be an ethernet network or a video network, and the second network may be a video network. That is to say, by applying the technical solution in the embodiment of the present invention, the monitoring client in the ethernet may request to perform the monitoring operation on the target monitoring data in the video network, or the monitoring client in one video network may request to perform the monitoring operation on the target monitoring data in another video network.
Based on the above description about a method for processing monitoring data, a method for regulating flow of monitoring data across a network is described below. As shown in fig. 2, a monitoring client in the ethernet network requests to retrieve target monitoring data in the internet of view. The Ethernet can comprise a monitoring client, a first monitoring server and a monitoring terminal management server, and the monitoring client is in communication connection with the first monitoring server and the monitoring terminal management server respectively. The video network can comprise a second monitoring server and a cooperative conversion server, and the second monitoring server is in communication connection with the cooperative conversion server. A monitoring client may have a plug-in installed on its browser that may request a call flow from the first monitoring server using customized session initiation protocol directives. Embodiments of the present invention may refer to this plug-in as an IE plug-in. The first monitoring server can be understood as a server which specially provides a monitoring data stream adjusting function for the IE plug-in.
And the IE plug-in sends an inquiry request to the monitoring terminal management server so as to inquire the number and the channel number of the protocol conversion server corresponding to the target monitoring data from the monitoring terminal management server. And the IE plug-in generates monitoring request information according to the serial number and the channel number obtained by inquiry, and sends the monitoring request information to the first monitoring server. After receiving the monitoring request information, the first monitoring server inquires whether a target monitoring channel of the target monitoring data exists or not, and if so, the first monitoring server distributes relevant information of the target monitoring channel to the IE plugin. If the target monitoring channel does not exist, the monitoring request information is forwarded to the second monitoring server through the private protocol, and the second monitoring server establishes the target monitoring channel according to the monitoring request information. When the second monitoring server establishes the target monitoring channel, the second monitoring server can access the internet of view through the virtual terminal number, then initiates a flow adjusting request of target monitoring data to the coordination transfer server, and the coordination transfer server establishes the target monitoring channel according to the flow adjusting request and returns the target monitoring data to the second monitoring server. And the second monitoring server returns the related information of the newly established target monitoring channel to the first monitoring server, and the first monitoring server distributes the received related information of the target monitoring channel to the IE plugin. And the second monitoring server returns the target monitoring data to the first monitoring server through the target monitoring channel.
After receiving the monitoring closing information of the IE plugin, the first monitoring server checks whether other IE plugins are monitoring the target monitoring data by using the target monitoring channel. If so, no operation is performed on the target supervisory channel. And if the target monitoring channel does not exist, sending monitoring closing information to the second monitoring server, and closing the target monitoring channel by the second monitoring server according to the monitoring closing information.
The method for processing monitoring data provided by the embodiment of the invention can be applied to a first monitoring server located in a first network, and the first network can also comprise a monitoring client besides the first monitoring server. And the monitoring client sends monitoring request information of the target monitoring data to the first monitoring server. The first monitoring server inquires whether a target monitoring channel of the target monitoring data exists according to the monitoring request information, and if the target monitoring channel exists, the relevant information of the target monitoring channel is returned to the monitoring client so that the monitoring client can monitor the target monitoring data by utilizing the relevant information of the target monitoring channel.
After receiving the monitoring request information of the monitoring client, the first monitoring server of the embodiment of the invention does not immediately establish the monitoring channel according to the monitoring request information, but firstly queries whether a target monitoring channel corresponding to the target monitoring data exists. And when the target monitoring channel exists, returning the relevant information of the target monitoring channel to the monitoring client. The monitoring client can monitor the target monitoring data by using the related information of the target monitoring channel. In the embodiment of the invention, under the condition that the first monitoring server has the target monitoring channel, the process of repeatedly establishing the target monitoring channel is avoided, the operating pressure of the first monitoring server is reduced, and the network bandwidth is saved.
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.

The metropolitan area server is a node which plays a centralized control function in the metropolitan area network and can control a node switch and a node server. The metropolitan area server can be directly connected with the node switch or directly connected with the node server.
Therefore, the whole video network is a network structure with layered centralized control, and the network controlled by the node server and the metropolitan area server can be in various structures such as tree, star and ring.
The access network part can form a unified video platform (the part in the dotted circle), and a plurality of unified video platforms can form a video network; each unified video platform may be interconnected via metropolitan area and wide area video networking.
Video networking device classification
1.1 devices in the video network of the embodiment of the present invention can be mainly classified into 3 types: servers, switches (including ethernet gateways), terminals (including various set-top boxes, code boards, memories, etc.). The video network as a whole can be divided into a metropolitan area network (or national network, global network, etc.) and an access network.
1.2 wherein the devices of the access network part can be mainly classified into 3 types: node servers, access switches (including ethernet gateways), terminals (including various set-top boxes, code boards, memories, etc.).
The specific hardware structure of each access network device is as follows:
a node server:

the network interface module 501, the CPU module 503 and the disk array module 504 all enter the switching engine module 502; the switching engine module 502 performs an operation of looking up the address table 505 on the incoming packet, thereby obtaining the direction information of the packet; and stores the packet in a corresponding queue of the packet buffer 506 based on the packet's steering information; if the queue of the packet buffer 506 is nearly full, it is discarded; the switching engine module 502 polls all packet buffer queues for forwarding if the following conditions are met: 1) the port send buffer is not full; 2) the queue packet counter is greater than zero. The disk array module 504 mainly implements control over the hard disk, including initialization, read-write, and other operations of the hard disk; the CPU module 503 is mainly responsible for protocol processing with an access switch and a terminal (not shown in the figure), configuring an address table 505 (including a downlink protocol packet address table, an uplink protocol packet address table, and a data packet address table), and configuring the disk array module 504.
The access switch:
as shown in fig. 6, the network interface module (downlink network interface module 601, uplink network interface module 602), switching engine module 603, and CPU module 604 are mainly included;
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, which in this embodiment of the present invention is divided into 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;

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 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.
