And S12, determining the terminal carrying the target identifier in the terminal information as the target terminal.
The target identifier is identification information which is distinguished from other terminals by the target terminal, and the data message associated with the target terminal can be scheduled preferentially. Specifically, the target identifier may be a VIP identifier, and the controller may identify whether the terminal information corresponding to each terminal carries the VIP identifier, and determine the terminal carrying the VIP identifier as the target terminal.
And S13, when the target terminal exists in the terminals participating in the target multimedia conference, determining a target switch associated with the target terminal and acquiring a priority forwarding strategy.
The priority forwarding strategy is used for carrying out priority scheduling on the data message associated with the target terminal, when the target terminal exists in the terminals participating in the target multimedia conference, the controller can determine the target switch associated with the target terminal according to the target multimedia conference information and simultaneously acquire the priority forwarding strategy corresponding to the current target terminal.

In the method for enhancing multimedia conference quality provided by this embodiment, the controller timely sends a priority forwarding policy to a target switch associated with a target terminal through target multimedia conference information reported by a real-time monitoring switch side when the target terminal exists in terminals monitoring a participating target multimedia conference, so as to ensure that the target switch can control a data packet to be preferentially scheduled in a communication link where the target terminal is located according to the priority forwarding policy, thereby ensuring data packet transmission quality between the target terminal and other terminals participating in the target multimedia conference, enhancing quality assurance of the target terminal in the multiparty multimedia conference, and improving internet conference experience of the target terminal.
In this embodiment, a method for enhancing multimedia conference quality is provided, which can be used in electronic devices, such as controllers corresponding to mobile phones, tablet computers, and the like, and fig. 3 is a flowchart for enhancing multimedia conference quality according to an embodiment of the present invention, and as shown in fig. 3, the flowchart includes the following steps:
and S21, acquiring target multimedia conference information reported by each switch, wherein the target multimedia conference information comprises a conference identifier corresponding to the target multimedia conference and terminal information of a terminal associated with the conference identifier.

And S23, when the target terminal exists in the terminals participating in the target multimedia conference, acquiring the priority level corresponding to the target terminal.
The priority level corresponding to the target terminal is the priority level of the target terminal, and the priority level may be determined based on the terminal level of the target terminal, that is, the higher the terminal level is, the higher the priority level is. For example, the terminal level of the target terminal is VIP1 level, and the priority level thereof is QOS 1; if the terminal level of the target terminal is the VIP2 level, its priority level is QOS2, and QOS2 is greater than QOS 1.
And S24, associating the priority level with the target multimedia conference.

And S27, when the target terminal does not exist in the terminals participating in the target multimedia conference, issuing tunnel identifiers corresponding to all the switches so that all the switches control the transmission scheduling of the data message according to the tunnel identifiers.
The tunnel identifier is used for representing a transmission channel of the switch, when a target terminal does not exist in terminals participating in a target multimedia conference, data interaction is performed between the terminals through the MCU, a priority identifier does not exist in a data message, the data message can only be normally forwarded between the switches, at the moment, the controller can issue a Segment Routing (SR) label for data message transmission to each switch, and the SR label is the tunnel identifier corresponding to the switch. And the switches encapsulate the SR labels into the data messages, and control the data messages to transmit and schedule among the switches according to the SR labels.
In the method for enhancing multimedia conference quality provided by this embodiment, when a target terminal does not exist in terminals participating in a target multimedia conference, a tunnel identifier corresponding to a switch is issued, so that the switch can control data packets to be transmitted between the switches according to the tunnel identifier, that is, the data packets are normally forwarded, thereby ensuring that each terminal in the multimedia conference can perform normal data transmission. When a target terminal exists in the terminals participating in the multimedia conference, the controller associates the priority level with the target multimedia conference by acquiring the priority level of the target terminal so as to ensure that each terminal participating in the target multimedia conference can share the priority level, thereby ensuring the data transmission quality among the terminals participating in the target multimedia conference.

And S32, when the target multimedia conference is established, acquiring terminal information corresponding to each terminal participating in the target multimedia conference and a conference identifier corresponding to the target multimedia conference.
Different conferences correspond to different conference identifiers, and after the fact that the target multimedia conference is established among the plurality of terminals is monitored, the exchanger can determine the conference identifier ID corresponding to the target multimedia conference. Meanwhile, the switch can determine each terminal participating in the target multimedia conference according to the monitored establishment state of the target multimedia conference, and acquire the terminal information of each terminal.

In this embodiment, a method for enhancing multimedia conference quality is provided, which can be used for electronic devices, such as switches corresponding to mobile phones, tablet computers, and the like, and fig. 5 is a flowchart for enhancing multimedia conference quality according to an embodiment of the present invention, and as shown in fig. 5, the flowchart includes the following steps:
and S41, acquiring the establishment state of the target multimedia conference. For a detailed description, refer to the related description of step S31 corresponding to the above embodiment, and the detailed description is omitted here.
And S42, when the target multimedia conference is established, acquiring terminal information corresponding to each terminal participating in the target multimedia conference and a conference identifier corresponding to the target multimedia conference. For a detailed description, refer to the related description of step S32 corresponding to the above embodiment, and the detailed description is omitted here.
And S43, generating target multimedia conference information based on the conference identifier and the terminal information, and sending the target multimedia conference information to the controller so that the controller issues a priority forwarding strategy according to the terminal information. For a detailed description, refer to the related description of step S33 corresponding to the above embodiment, and the detailed description is omitted here.
And S44, receiving the priority forwarding strategy issued by the controller, and controlling the data message to perform transmission scheduling in the communication link where the target terminal is located based on the priority forwarding strategy, where the target terminal is a terminal carrying a target identifier in the terminal information, and the data message carries a priority identifier corresponding to the priority forwarding strategy.
Specifically, the step S44 may include the following steps:
s441, the data message to be scheduled is obtained.
The data message to be scheduled is a message sent by a terminal in the target multimedia conference or a message which is mixed by the MCU and then is forwarded to each terminal participating in the target multimedia conference. The switch can acquire the data messages reported by each terminal participating in the target multimedia conference and control the data messages to carry out data interaction through the switch.
S442, matching item information corresponding to the data message is analyzed.
The matching item information is used for identifying the source of the data message, and comprises a message source IP, an RTP SSRC, a destination IP and a destination port. For the switch connected with the terminal, the message source IP is a terminal address, the destination IP is an MCU address, and the RTP SSRC is audio and video source information of the multimedia conference and corresponds to the multimedia conference with a conference identifier; for the switch connected with the MCU, the message source IP is the MCU address, the destination IP is the address of each terminal, and the RTP SSIC is the audio and video source information after the MCU is mixed.
S443, judging whether the matching item information hits the priority forwarding strategy.
The switch determines whether the data message corresponding to the matching item information hits the priority forwarding strategy according to the matching item information, if the matching item information hits the priority forwarding strategy, step S444 is executed, otherwise, the data message is represented as a normal message, and message scheduling is performed according to a normal forwarding flow.
And S444, performing priority transmission scheduling on the data message according to a priority forwarding strategy.
When the matching item information hits the priority forwarding strategy, the switch can schedule and forward the data message according to the priority level corresponding to the preferred forwarding strategy. Specifically, the switch may encapsulate an SR tag in the data packet, and forward the data packet after encapsulating the SR tag to an intermediate device (core switch), so that the intermediate device performs scheduling and forwarding of the packet according to the priority level.
Specifically, the step S444 may include:
(1) analyzing the encapsulation information of the data message, and determining the tunnel identifier and the priority identifier carried by the data message.
When the switch forwards the data message, the switch can analyze the data message and determine the encapsulation information, the tunnel identifier and the priority identifier carried by the current data message, namely the SR label and the VIP label. As shown in fig. 6, when the switch receives the data packet, the switch may parse the MAC address, the SR tag, the VIP tag, the IP address, the UDP information, the RTP information, and the audio/video data of the data packet.
(2) And determining a destination port corresponding to the data message based on the tunnel identifier.
The destination port is an output port of the data packet to be forwarded by the current switch, and the switch can forward the data packet to the corresponding destination port according to the SR label analyzed by the switch.
(3) And preferentially forwarding the data message to the destination port based on the priority identification.
When the data message is forwarded based on the SR tag, the switch may perform priority scheduling on the data message according to the analyzed VIP tag, and determine that the data message can be normally forwarded. If the current switch is a tail node switch, the current switch can perform priority scheduling according to the VIP label and perform message forwarding according to the analyzed IP address.
In the method for enhancing multimedia conference quality provided by this embodiment, the switch determines the matching item information corresponding to the data packet to be scheduled by analyzing the data packet to be scheduled, and determines whether the data packet to be scheduled needs to be preferentially scheduled according to whether the matching item information hits the preferential forwarding policy, so that it is further ensured that the data packet in the data link where the target terminal is located can be preferentially scheduled, thereby enhancing the data transmission quality of each terminal in the multimedia conference where the target terminal is located, and further improving the conference quality of the target terminal. The switch determines a tunnel identifier and a priority identifier carried by the data message by analyzing the encapsulation information of the data message; and determining a destination port corresponding to the data message based on the tunnel identifier, and preferentially forwarding the data message to the destination port based on the priority identifier, thereby ensuring that the data message can be preferentially transmitted to the destination port, and simultaneously considering the transmission efficiency and the transmission accuracy of the data message.

The Leaf2 forwards the data message to the middleware Spine according to the QOS1 scheduling, wherein the data message is an SR message carrying an SR label and a VIP label;
the intermediate equipment Spine receives the SR message, forwards the message to Leaf3 according to the SR label, and simultaneously schedules and forwards the message to an exit port according to the VIP label by QOS 1;
the Leaf3 receives the SR message, pops off the SR tunnel, forwards the message to the MCU, and simultaneously schedules a QOS1 to an output port according to the VIP label;
the MCU re-forwards the mixed data to Leaf3, Leaf3 is the switch connected to the MCU, the message source IP is the MCU, the destination IP is the rest of the terminals (if the address is unicast, multiple copies are made and sent to each terminal), RTP SSRC is the MCU (VIP conference);
matching a priority forwarding strategy on the Leaf3, identifying the priority level of the data message as QOS1, and identifying the exit tunnel label as SR label and VIP label, and forwarding the data message to Spine according to the priority scheduling of QOS 1. If the destination IP is host3, then the Leaf3 directly forwards the destination IP to host3 according to QOS1 priority scheduling without encapsulating a tunnel label;
spine receives the SR message, forwards the SR message to Leaf1 according to the SR label, and forwards the SR message to Leaf1 by performing QOS1 scheduling according to the VIP label;
the Leaf1 receives the SR message, pops off the SR tunnel, forwards the data message to the host1, and simultaneously carries out QOS1 scheduling to the exit port according to the VIP label.
