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 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., 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.

Based on the characteristics of the video network, the processing scheme of the packet loss rate provided by the embodiment of the invention follows the protocol of the video network, and visualizes the packet loss rate of the video network terminal, thereby facilitating the user to investigate and solve the problems.

Example one

The method for processing the packet loss rate can be applied to video networking, and particularly can be applied to video networking conferences, wherein the video networking conferences can be video conferences, audio conferences and the like. In the video networking conference mentioned in the embodiment of the present invention, the related devices may include a video networking terminal, a video networking server, a video networking conference database, and a video networking conference management platform.

The video networking conference management platform is used for managing each video networking conference, the video networking conference database is used for storing relevant information in the video networking conference, and the video networking server is used for providing services for video networking terminals participating in the video networking conference. The video networking conference management platform can be connected with a plurality of video networking servers, and one video networking server can be connected with a plurality of video networking terminals. The video networking conference management platform can perform bidirectional interaction with a video networking conference database, the video networking conference management platform can also perform bidirectional interaction with a video networking server, the video networking server can perform bidirectional interaction with the video networking conference database, and the video networking server can also perform bidirectional interaction with a video networking terminal.

The video network terminal is a video network service landing device, an actual participant or a server of the video network service, and can be various conference set-top boxes, video telephone set-top boxes, operation teaching set-top boxes, streaming media gateways, storage gateways, media synthesizers and the like. The terminal of the video network needs to be registered on the video network server to carry out normal service.

Referring to fig. 5, a flowchart illustrating a method for processing a packet loss ratio according to a first embodiment of the present invention is shown.

The method for processing the packet loss rate in the embodiment of the invention can comprise the following steps:

step 501, each video network terminal participating in the video network conference detects its own packet loss rate, and uploads the packet loss rate to the video network conference database via the video network server connected to itself.

In a video network conference, a plurality of video network terminals can participate. Each video networking terminal participating in the video networking conference can receive conference data sent by other video networking terminals in the video networking conference and can also send conference data to other video networking terminals in the video networking conference, so that bidirectional communication in the video networking conference is realized. The conference data may include audio data, video data, and the like.

In the embodiment of the invention, when the video networking conference is carried out and the video networking terminals communicate with each other through the video networking, the packet loss is caused. Each video network terminal participating in the video network conference can respectively detect the packet loss rate of the terminal. The packet loss rate of the detection itself may be detected at regular time intervals, for example, once every 5s, 10s, and the like, which is not limited in this embodiment of the present invention.

In a specific implementation, the conference data received by the video networking terminal may include a plurality of data packets having a sequence, each data packet has a corresponding number, and some data packets may be lost during the transmission of the conference data (e.g., during the transmission from the sender to the receiver). After receiving the conference data, the video networking terminal may detect whether a data packet in the received conference data is complete, for example, detect whether the data packet in the received conference data is complete and how many data packets are lost according to a data number of the data packet, thereby determining a packet loss rate. The packet loss rate may include an audio packet loss rate, a video packet loss rate, and the like.

After each video network terminal detects the packet loss rate of the video network terminal, the video network terminal uploads the packet loss rate of the video network terminal to a video network conference database. Because the video network terminal is not directly connected with the video network conference database, the video network terminal can upload the packet loss rate of the video network terminal to the video network conference database through the video network server connected with the video network terminal. Specifically, the video networking terminal sends the packet loss rate of the video networking terminal to a video networking server connected with the video networking terminal, and the video networking server uploads the packet loss rate of the video networking terminal to a video networking conference database.

In one particular implementation, the video networking terminal and the video networking server may interact based on a video networking protocol, and the video networking server and the video networking conference database may interact based on an internet protocol. Therefore, the video network terminal encapsulates data such as packet loss rate and identification information of the video network terminal into a first video network protocol data packet based on a video network protocol, and sends the first video network protocol data packet to the video network server through the video network. The video network server has a protocol conversion function, and the video network server converts the first video network protocol data packet based on the video network protocol into a first internet protocol data packet based on an internet protocol. And after the protocol conversion, the video networking server uploads the first Internet protocol data packet to a video networking conference database through the Internet.

The embodiment of the invention can also be provided with an acquisition layer, and the acquisition layer can acquire the first internet Protocol data packet obtained after conversion from the video networking server in a TCP (Transmission Control Protocol) connection mode and the like and upload the first internet Protocol data packet to the video networking conference database.

Therefore, the video networking conference database stores information of each video networking terminal participating in the video networking conference, such as identification information of the video networking terminal, packet loss rate and the like. And when the packet loss rate uploaded by the video networking terminal changes, the video networking conference database correspondingly updates the information of the video networking terminal. The identification information may include a unique identifier such as a user number of the video networking terminal.

Step 502, the video networking conference management platform sends a query request to the video networking conference database.

When the video network conference management platform has a requirement for acquiring the packet loss rate of a certain or some video network terminals, the video network conference management platform can send an inquiry request to a video network conference database so as to inquire the packet loss rate of the video network terminal which is required to be acquired. Specifically, the video networking conference management platform encapsulates the query request into a second internet protocol data packet based on the internet protocol, and sends the second internet protocol data packet to the video networking conference database through the internet.

In one particular implementation, the video networking conference management platform may include a Web-side, which may include front-end pages and back-end services. Specifically, the front-end page can transmit the identification information of the target video network terminal to be inquired and the like to the back-end service; and then, generating a query request comprising the identification information of the target video network terminal by the back-end service, packaging the query request into a second internet protocol data packet, and sending the second internet protocol data packet to a video network conference database through the internet.

The identification information of the target video network terminal can be automatically acquired by the front-end page according to the requirement. For example, the video networking conference may include roles of a chairman party, a speaking party, a participating party, and the like, and the front-end page may acquire identification information of one or more chairman party video networking terminals in the video networking conference currently in progress, as identification information of the target video networking terminal. Identification information of the target video network terminal may also be entered by the user. For example, an input box may be displayed in the front-end page, and a user may input identification information of one or more target video network terminals in the input box; or a selection frame of each video network terminal can be displayed in the front-end page, a user can select one or more target video network terminals, and the front-end page acquires identification information of the target video network terminal selected by the user.

Step 503, the video networking conference management platform receives the packet loss rate of the target video networking terminal, which is returned by the video networking conference database and is obtained according to the identification information.

After receiving the query request sent by the video networking conference management platform, the video networking conference database can determine which video networking terminal or terminals to be queried according to the identification information of the target video networking terminal included in the query request, acquire the packet loss rate of the target video networking terminal, and return the packet loss rate of the target video networking terminal to the video networking conference management platform.

Specifically, the video networking conference database may encapsulate information such as identification information and packet loss rate of the target video networking terminal into a third internet protocol data packet based on an internet protocol, and return the third internet protocol data packet to the video networking conference management platform based on the internet.

And step 504, the video networking conference management platform displays the packet loss rate of the target video networking terminal.

And after receiving a third internet protocol data packet returned by the video networking conference database, the video networking conference management platform analyzes the third internet protocol data packet to obtain identification information, packet loss rate and other information of the target video networking terminal, and can display the identification information and the packet loss rate of the target video networking terminal.

In a specific implementation, a back-end service of a Web end of a video networking conference management platform receives a third video networking protocol data packet, and analyzes the third video networking protocol data packet to obtain identification information and a packet loss rate of a target video networking terminal; and then the back-end service transmits the identification information and the packet loss rate of the target video network terminal to the front-end page, and the front-end page displays the identification information and the packet loss rate.

According to the embodiment of the invention, the video networking terminal participating in the video networking conference actively reports the packet loss rate, the video networking conference management platform can inquire the packet loss rate reported by the video networking terminal and display the packet loss rate of the video networking terminal, so that the packet loss rate is visualized on the video networking conference management platform, a user can analyze the reason causing audio and video jam according to the displayed packet loss rate, the time for checking the reason is saved, the problem can be solved quickly, and the user experience is improved.

Example two

Referring to fig. 6, a flowchart illustrating a method for processing a packet loss ratio according to a second embodiment of the present invention is shown.

step 601, each video network terminal participating in the video network conference detects its own packet loss rate, and uploads the packet loss rate to the video network conference database via the video network server connected to itself.

Step 602, the video networking conference management platform sends a query request to the video networking conference database.

Step 603, the video networking conference management platform receives the packet loss rate of the target video networking terminal, which is returned by the video networking conference database and is obtained according to the identification information.

And step 604, displaying the packet loss rate of the target video networking terminal by the video networking conference management platform.

In the embodiment of the present invention, steps 601 to 604 are the same as steps 501 to 504 in the first embodiment, and specific reference is made to the related description of the first embodiment, which is not discussed in detail in the embodiment of the present invention.

Step 605, the video networking conference management platform determines the packet loss reason of the target video networking terminal according to the packet loss rate, and displays the packet loss reason.

In the embodiment of the invention, the video networking conference management platform can also determine the packet loss reason of the target video networking terminal according to the packet loss rate of the target video networking terminal aiming at each video networking terminal.

In a specific implementation, a first packet loss rate threshold may be preset, and the first packet loss rate threshold is mainly used as a reference basis for determining a reason for packet loss. The step of determining, by the video networking conference management platform, the packet loss reason of the target video networking terminal according to the packet loss rate may include: the video networking conference management platform judges whether the packet loss rate of the target video networking terminal is greater than a preset first packet loss rate threshold value or not; if so, determining that the reason for packet loss of the target video networking terminal is the reason of the equipment of the target video networking terminal; and if not, determining that the packet loss reason of the target video networking terminal is the reason of network connection.

For setting the first packet loss rate threshold, a person skilled in the art may select any suitable value according to practical experience, which is not limited in this embodiment of the present invention. For example, the first packet loss rate threshold may be set to be 60%, and when the packet loss rate of the target video networking terminal is greater than 60%, it may be considered that packet loss is caused by the device of the target video networking terminal, for example, a device fails, a device setting limit is set, and the like; when the packet loss rate of the target video network terminal is less than or equal to 60%, it may be considered that the packet is lost due to network connection, such as slow network speed, disconnection of network connection, and the like.

The video networking conference management platform determines the packet loss reason of the target video networking terminal and displays the packet loss reason aiming at the target video networking terminal so that a user can more visually see the packet loss reason and the blockage reason. Specifically, a back-end service of a Web end of a video networking conference management platform determines a packet loss reason of a target video networking terminal; and then the back-end service transmits the reason of the packet loss to the front-end page, and the front-end page displays the reason of the packet loss.

Step 606, if the video networking conference management platform determines that the packet loss rate of the target video networking terminal is greater than a preset second packet loss rate threshold value, displaying alarm information for the target video networking terminal.

In the embodiment of the invention, the video networking conference management platform can also give an alarm aiming at the target video networking terminal according to the packet loss rate of the target video networking terminal so as to inform a user that the current packet loss rate of the target video networking terminal has great influence on audio and video playing.

In a specific implementation, a second packet loss rate threshold may also be preset, where the second packet loss rate threshold is mainly used as a reference for determining whether to alarm. The second packet loss rate threshold is smaller than the first packet loss rate threshold. The video network conference management platform can judge whether the packet loss rate of each target video network terminal is greater than a preset second packet loss rate threshold value or not aiming at each target video network terminal, and if so, alarm information can be displayed aiming at the target video network terminal. Specifically, a back-end service of a Web end of the video network conference management platform judges for each target video network terminal, and generates alarm information for the target video network terminal with the packet loss rate larger than a preset second packet loss rate threshold; and then the rear-end service transmits the alarm information to the front-end page, and the front-end page displays the alarm information.

For setting the second packet loss rate threshold, a person skilled in the art may select any suitable value according to practical experience, which is not limited in this embodiment of the present invention. For example, the second packet loss rate threshold may be set to be 30%, and when the packet loss rate of the target video networking terminal is greater than 30%, it may be considered that the current packet loss rate has a large influence on the playing of the audio and video, so that an alarm may be given to prompt a user to process in time; when the packet loss rate of the target video network terminal is less than or equal to 30%, the current packet loss rate is considered to have a smaller influence on the playing of the audio and video, so that the alarm can be temporarily avoided.

Step 607, the video networking conference management platform sends the prompt information to the video networking server connected with the target video networking terminal according to the packet loss rate of the target video networking terminal, and the video networking server connected with the target video networking terminal executes the corresponding operation according to the prompt information.

In the embodiment of the invention, the video networking conference management platform can also send prompt information to the video networking server according to the packet loss rate of the target video networking terminal so as to prompt the video networking server to perform corresponding processing.

In a preferred embodiment, this step 607 may include: if the video networking conference management platform judges that the packet loss rate of the target video networking terminal is greater than a preset second packet loss rate threshold value and less than or equal to a preset first packet loss rate threshold value, sending first prompt information to a video networking server connected with the target video networking terminal; and the video network server connected with the target video network terminal selects a virtual terminal except the virtual terminal currently connected with the target video network terminal according to the first prompt message, and switches the selected virtual terminal for the target video network terminal.

If the video networking conference management platform judges that the packet loss rate of the target video networking terminal is greater than the preset second packet loss rate threshold and less than or equal to the preset first packet loss rate threshold, the packet loss reason can be considered as the reason of network connection, and the current packet loss rate can already influence the audio and video playing. Therefore, the video network conference management platform can send the first prompt message to the video network server aiming at the target video network terminal. Specifically, the video networking conference management platform may encapsulate the first prompt information into a fourth internet protocol data packet based on the internet protocol, and send the fourth internet protocol data packet to the video networking server through the internet. The first prompt message may include identification information of the target video network terminal, a first prompt reason, and a packet loss rate, where the packet loss rate is greater than a preset second packet loss rate threshold and less than or equal to a preset first packet loss rate threshold, and the first prompt reason may be: the reason for packet loss is the reason for network connection, and the current packet loss rate can already affect the audio and video playing.

A plurality of virtual terminals can be created in the video network server, and the virtual terminals can be understood as channels for transmitting information (such as signaling, data and the like) in the video network server. Therefore, after the video network terminal joins the video network conference, the video network server allocates a virtual terminal for the video network terminal to use for transmitting information. If the video network server receives the first prompt message aiming at a certain target video network terminal, the virtual terminal can be switched for the target video network terminal so as to improve the condition of higher packet loss rate.

In a preferred embodiment, this step 607 may include: if the video networking conference management platform judges that the packet loss rate of the target video networking terminal is greater than a preset first packet loss rate threshold value, sending second prompt information to a video networking server connected with the target video networking terminal; and the video network server connected with the target video network terminal sends the second prompt information to the target video network terminal according to the second prompt information and the downlink communication link configured for the target video network terminal.

If the video networking conference management platform judges that the packet loss rate of the target video networking terminal is greater than the preset first packet loss rate threshold value, the packet loss reason can be considered to be the reason of the device of the video networking conference management platform. Therefore, the video network conference management platform can send the second prompt message to the video network server aiming at the target video network terminal. Specifically, the video networking conference management platform may encapsulate the second prompt information into a fifth internet protocol data packet based on the internet protocol, and send the fifth internet protocol data packet to the video networking server through the internet. The second prompt information may include identification information of the target video networking terminal whose packet loss rate is greater than a preset first packet loss rate threshold, a second prompt reason, a packet loss rate, and other information, and the second prompt reason may be: the reason for the packet loss is the device itself.

If the video network server receives second prompt information aiming at a certain target video network terminal, the second prompt information can be sent to the target video network terminal so as to prompt the target video network terminal to perform corresponding processing.

In a specific implementation, the video network server converts a fifth internet protocol data packet based on the internet protocol encapsulation second prompt message into a second video network protocol data packet based on the video network protocol encapsulation second prompt message, and sends the second video network protocol data packet to the target video network terminal through the video network. Specifically, the video network server sends the second prompt message to the target video network terminal according to the downlink communication link configured for the target video network terminal.

In practical applications, the video network is a network with a centralized control function, and includes a master control server and a lower level network device, where the lower level network device includes a terminal, and one of the core concepts of the video network is to configure a table for a downlink communication link of a current service by notifying a switching device by the master control server, and then transmit a data packet based on the configured table.

Further, transmitting according to the downlink communication link includes: the configured table is consulted, and the switching equipment transmits the received data packet through the corresponding port.

In particular implementations, the services include unicast communication services and multicast communication services. Namely, whether multicast communication or unicast communication, the core concept of the table matching-table can be adopted to realize communication in the video network.

As mentioned above, the video network includes an access network portion, in which the master server is a node server and the lower-level network devices include an access switch and a terminal.

For the unicast communication service in the access network, the step of configuring the downlink communication link of the current service by the master server may include the following steps:

and a substep S11, the main control server obtains the downlink communication link information of the current service according to the service request protocol packet initiated by the source terminal, wherein the downlink communication link information includes the downlink communication port information of the main control server and the access switch participating in the current service.

In the substep S12, the main control server sets a downlink port to which a packet of the current service is directed in a packet address table inside the main control server according to the downlink communication port information of the control server; and sending a port configuration command to the corresponding access switch according to the downlink communication port information of the access switch.

In sub-step S13, the access switch sets the downstream port to which the packet of the current service is directed in its internal packet address table according to the port configuration command.

For a multicast communication service (e.g., video conference) in the access network, the step of the master server obtaining downlink information of the current service may include the following sub-steps:

in sub-step S21, the main control server obtains a service request protocol packet initiated by the target terminal and applying for the multicast communication service, where the service request protocol packet includes service type information, service content information, and an access network address of the target terminal.

Wherein, the service content information includes a service number.

And a substep S22, the main control server extracts the access network address of the source terminal in a preset content-address mapping table according to the service number.

In the substep of S23, the main control server obtains the multicast address corresponding to the source terminal and distributes the multicast address to the target terminal; and acquiring the communication link information of the current multicast service according to the service type information and the access network addresses of the source terminal and the target terminal.
