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 video networking is an important milestone for network development, is a real-time network, can realize high-definition video real-time transmission, and pushes a plurality of internet applications to high-definition video, and high-definition faces each other.
The video networking adopts a real-time high-definition video exchange technology, can integrate required services such as dozens of services of video, voice, pictures, characters, communication, data and the like on a system platform on a network platform, such as high-definition video conference, video monitoring, intelligent monitoring analysis, emergency command, digital broadcast television, delayed television, network teaching, live broadcast, VOD on demand, television mail, Personal Video Recorder (PVR), intranet (self-office) channels, intelligent video broadcast control, information distribution and the like, and realizes high-definition quality video broadcast through a television or a computer.
Referring to fig. 1, a flowchart of steps of a method for displaying an online state of a terminal according to an embodiment of the present invention is shown, where the method is applied to a video network, where the video network includes a conference control client, a terminal, a conference management scheduling platform, and a sky-eye scheduling system platform, and specifically includes the following steps:
In this embodiment, the conference control client may be a pamir client, and is configured to initiate and hold a video networking conference, after the conference is initiated, the pamir client invokes all terminals that need to participate in the conference, and sends a terminal online signaling to the conference management scheduling platform, where the terminal online signaling includes a conference identifier of the conference where the terminal is located, a terminal identifier corresponding to the terminal, and a conference state of the terminal, where the conference identifier is used to distinguish different conferences, and the terminal identifier is used to distinguish different terminals, and the conference state represents whether the terminal is in an online state or an offline state in the conference.
In a specific application, a user can only participate in one conference at the same time, so that the online state of one terminal only exists in one conference. The conference identifier may be an ID of the conference, or may be time, location, or other information that may uniquely represent the conference, and the terminal identifier may be an ID of the terminal device, which is not limited in the present invention.
In the embodiment of the invention, one pamir client can hold one conference, the terminal on-line signaling sent after the conference is held contains all the conference-participating terminals, the conference in which the conference-participating terminals are located and the conference state information, if the terminal already participates in one conference, the pamir client adds the terminal into other conferences again, the conference state of the terminal in other conferences is an off-line state, and the terminal in the off-line state does not participate in the conference. For example, the terminal a already participates in the conference 1, and is then added to the conference 2by the pamir client of the conference 2, because the terminal a still participates in the conference 1, the terminal a exists in the conference 2 in an offline state, and cannot participate in the conference 2, and the terminal online signaling sent by the pamir client of the conference 1 to the conference management scheduling center contains the terminal identifier of the terminal a, the conference identifier of the conference 1, and the information that the terminal a is in an online state; and the pamir client of the conference 2 sends a terminal on-line signaling containing the conference identifier of the conference 2 and the information that the terminal a is in an off-line state to the conference management scheduling center. It should be noted that the conference state in the terminal online signaling sent by the pamir client represents the real-time conference state of the terminal, and when the real-time conference state of the terminal changes, the pamir client will resend the terminal online signaling containing the changed real-time conference state of the terminal. In addition, in the embodiment of the present invention, the terminal a is added to the conference 1 first, and is added to the conference 2 again during the conference 1, so that the situation that the terminal a exists in the conference 1 and the conference 2 at the same time, and the conference management database stores two pieces of information, that is, the terminal a is in the online state in the conference 1, and the terminal a is in the offline state in the conference 2, may occur. If terminal a is only added to conference 1 and not to conference 2, only the information that terminal a is online in conference 1 is stored in the conference management database.
And step 102, summarizing the terminal identification in the online state from the real-time conference state.
The real-time conference state includes the terminal identifier in the offline state in addition to the terminal identifier in the online state, and the terminal identifier is in the offline state, that is, the terminal does not participate in the conference on behalf of the terminal.
And 103, sending the terminal identification in the online state and the conference identification of the conference where the corresponding terminal is located to the sky-eye scheduling system platform and displaying the terminal identification and the conference identification.
In the embodiment of the application, a sky-eye scheduling system platform, namely a GIS platform, is used for initiating a start scheduling operation. After a user logs in the GIS platform, if the user wants to send a start dispatching operation, the user can send a request to the meeting management dispatching center through the GIS platform so as to obtain the terminal in an online state. And after receiving the request of the GIS platform, the meeting management scheduling center sends the terminal identification of the terminal in the online state and the meeting identification of the meeting where the corresponding terminal is located to the GIS platform, and the GIS platform displays the terminal identification and the meeting identification to the user in a one-to-one corresponding mode according to the received terminal identification and the meeting identification. The user can check all the terminals participating in the conference and the conference in which each terminal participates through the GIS platform so as to decide whether to click on the terminals or not.
In the embodiment of the invention, after a conference is started by a pamir client, a terminal online signaling containing a terminal identifier, a conference identifier and an online state is sent to a conference management scheduling platform, the conference management scheduling platform updates the stored conference state of the terminal in the conference according to the received terminal online signaling, summarizes the terminal identifier of the terminal with the real-time conference state in the online state, sends the terminal identifier and the conference identifier of the conference where the corresponding terminal is located to a GIS platform together, and displays the terminal identifier and the conference identifier on the GIS platform. Because the pamir client sends the conference state of the terminal to the on-line signaling of the terminal of the conference management scheduling platform, the conference management scheduling platform can judge the conference where the terminal is currently located according to the real-time conference state of the terminal, so that the subsequent scheduling operation of the terminal can be normally performed, the problem that one terminal is present in two conferences, the conference management scheduling platform cannot judge the conference where the terminal is currently located, and further the scheduling operation cannot be performed is solved, the conference work can be normally carried out, and the loss caused by the fact that the conference cannot be held in time is avoided. In addition, the user can also decide whether to click the terminal according to the conference of the terminal corresponding to the terminal displayed on the GIS platform together with the terminal, so that the user experience is improved, and the development of work is facilitated.

In the embodiment of the application, a terminal, a conference in which the terminal is located and an online state are in one-to-one correspondence, the online state represents that a certain terminal is participating in a certain conference, and after a conference management scheduling platform receives a terminal online signaling, a real-time conference state used for representing the current conference participating state of the terminal is updated according to a terminal identifier, a conference identifier and the conference state of the terminal, which are included in the terminal online signaling, for example, if the terminal A participates in the conference 1, the updated real-time conference state is 'terminal A'; a conference 1; online ".
In a preferred embodiment of the present invention, the step 202 may include the following sub-steps:
according to the terminal identification and the conference identification of the conference in which the terminal is positioned, confirming the corresponding terminal and the conference in which the terminal is positioned in a conference management scheduling platform database;
and updating the real-time conference state of the terminal in the conference of the terminal according to the conference state of the terminal.
The conference management database stores terminal identification corresponding to the terminal and conference identification corresponding to the conference, and after receiving the terminal on-line signaling, the corresponding terminal and the conference in which the terminal is located can be determined in the conference management database according to the conference identification and the terminal identification of the conference in which the terminal is located, which are contained in the terminal on-line signaling. The conference state of the terminal represents the real-time conference state of the terminal in the conference in which the terminal is positioned, if the conference state of the terminal is the online state, the real-time online state of the terminal in the conference stored in the management database is updated to the online state, and if the conference state of the terminal is the offline state, the real-time online state of the terminal in the conference stored in the management database is updated to the offline state. For example, if the conference management scheduling platform receives 2 terminal on-line signaling, which respectively includes that the terminal a is in an on-line state in the conference 1 and the terminal a is in an off-line state in the conference 2, the conference management scheduling platform updates the real-time conference state of the terminal a in the management database to be "terminal a"; a conference 1; online status "and" terminal a; a conference 2; offline status ".
And step 203, summarizing the terminal identification in the online state from the real-time conference state.
And after the conference state of the conference in which the terminal is positioned in the conference management scheduling center in the conference management database is updated, summarizing according to the updated real-time conference state, and summarizing the terminal identification of the terminal in the online state and the conference identification of the conference corresponding to the online terminal. If the meeting management database stores 'terminal A'; a conference 1; online status "," terminal a; a conference 2; offline status "and" terminal B; a conference 2; online state ", the result after the summary is" terminal a; a conference 1; online status "and" terminal B; a conference 2; online status ".
And 204, sending the terminal identification in the online state and the conference identification of the conference where the corresponding terminal is located to the sky-eye scheduling system platform and displaying the terminal identification and the conference identification.
In the embodiment of the application, a user can send a request for acquiring all terminals participating in a conference and the conference in which each terminal is participating through the GIS platform, and can also send a request containing a terminal identifier of a target terminal which the user wants to perform point adjustment to the conference management scheduling center through the GIS platform, after receiving the request containing the terminal identifier of the target terminal sent by the user, the conference management scheduling center returns the terminal identifier of the target terminal and the conference identifier of the current online conference of the target terminal to the GIS platform, and the user can check the conference where the target terminal is located on the GIS platform and determine whether to perform point adjustment.
The GIS platform displays the terminal corresponding to the terminal identification acquired from the conference management scheduling platform and the conference where the terminal corresponding to the conference identification is located, a user selects a terminal needing to be called on the GIS platform, namely a target terminal, and a conference called into by the target terminal, namely after the target is called into the conference, the GIS platform acquires the conference identification of the target called-in conference according to the conference selected by the user, and generates a calling instruction based on the conference identification of the target called-in conference, the conference identification of the conference where the target terminal is currently located and the terminal identification of the target terminal. And after the conference management scheduling platform receives the point scheduling instruction sent by the GIS platform, controlling the target terminal to call the target access conference from the current conference according to the conference identifier of the target access conference, the conference identifier of the current conference of the target terminal and the terminal identifier of the target terminal contained in the point scheduling instruction.
In a preferred embodiment of the present invention, the step 205 may include the following sub-steps:
disconnecting the target terminal from the current conference of the target terminal;

For example, the received click-to-tune execution instruction is the target terminal: a terminal A; the conference of the target terminal: a conference 1; target-call conference: conference 3, when executed, disconnects terminal a from conference 1, and then connects terminal a to conference 3.
And step 206, receiving a terminal online signaling sent by the conference control client of the target call-in conference, and updating the terminal online signaling into the conference management scheduling platform database.
After the target terminal is connected with the target call-in conference, the pamir client of the target call-in conference sends the terminal on-line signaling of the terminal participating in the conference to the conference management scheduling platform, and updates the terminal in the conference management database, the conference where the terminal is located and the real-time on-line state of the terminal in the conference where the terminal is located according to the terminal on-line signaling, so as to be used when the follow-up call-in is needed.
In the embodiment of the invention, the real-time conference state of the terminal stored in the conference management database is updated according to the terminal online signaling sent by the pamir client, the terminal identification of the terminal in the online state and the conference identification of the corresponding conference are sent to the GIS platform, after the click-tuning instruction returned by the GIS platform is received, the conference management scheduling platform completes the click-tuning of the target terminal according to the click-tuning instruction, and then the real-time conference state of the target terminal and the conference are updated into the conference management database. The real-time update of the conference state of the terminal in the conference is kept, so that the follow-up operation can be normally carried out when the on-demand operation is required, and the conference holding efficiency is improved.

Networking of the video network is as follows:
the video network is a centralized control network structure, and the network can be a tree network, a star network, a ring network and the like, but on the basis of the centralized control node, the whole network is controlled by the centralized control node in the network.
As shown in fig. 5, the video network is divided into an access network and a metropolitan network.
The devices of the access network part can be mainly classified into 3 types: node server, access switch, terminal (including various set-top boxes, coding boards, memories, etc.). The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.
The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server can be directly connected with the access switch or directly connected with the terminal.
Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.
The node server is a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.
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.

6. Video networking packet definition
6.1 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.
6.2 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.
