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 video conference provided by the embodiment of the invention follows the protocol of the video network, and can realize that an internet terminal can also participate in the video conference of the video network.
Example one
The video conference processing method can be applied to video networking. The video network can comprise a streaming media server, a video network server (can be the node server) and a plurality of video network terminals, and the internet can comprise a plurality of internet terminals. The video network server can be connected with a plurality of video network terminals, and the video network server and the video network terminals can perform bidirectional interaction based on a video network protocol. The video network server is connected with the streaming media server, and the video network server and the streaming media server can perform bidirectional interaction based on a video network protocol. The streaming media server can be connected with a plurality of internet terminals, and the streaming media server and the internet terminals can perform bidirectional interaction based on internet protocols (such as IP protocols).
The internet terminal may include a software terminal such as a palm top installed on a mobile terminal or the like, and may also include other terminals such as a tablet computer or the like. The video networking terminals may include various conference set-top boxes, video telephony set-top boxes, surgical teaching set-top boxes, media synthesizers, and the like.
Each video network terminal connected with the video network server needs to be registered above the video network server in advance to perform normal service. After registration, the video network server allocates information such as a video network number and a Media Access Control (MAC) address to the video network terminal. And the video networking terminal and the video networking server interact based on the video networking number and the video networking MAC address.
The streaming media server is mainly used for realizing the operations of conversion, interaction and the like of data in the internet and data in the video network. The streaming media server can comprise a plurality of virtual terminals, and the streaming media server can interact with the video network server through the virtual terminals. Each virtual terminal can be seen as a simulated video networking terminal. Therefore, each virtual terminal in the streaming server connected to the video network server also needs to register in advance above the video network server to enable normal services. After registration, the video network server distributes information such as a video network number, a video network MAC address and the like for the virtual terminal. And the virtual terminal and the video network server interact based on the video network number and the video network MAC address.
The streaming media server can interact with the internet terminal through the virtual terminal. Each internet terminal connected with the streaming media server can be registered on the streaming media server in advance and obtain a registered account. After the registration, the streaming media server binds a virtual terminal for the internet terminal, that is, binds the registration account of the internet terminal with the virtual terminal. And the subsequent internet terminal can interact with the virtual terminal bound with the internet terminal. Therefore, the plurality of virtual terminals are bound with the plurality of internet terminals one by one.
Referring to fig. 5, a flowchart illustrating steps of a method for processing a video conference according to a first embodiment of the present invention is shown.
The processing method of the video conference of the embodiment of the invention can comprise the following steps:
When a video conference on the internet needs to be created, the user can perform corresponding operations on the conference control software, such as selecting a plurality of invited terminals, setting the authority of each invited terminal, and the like. The invited terminal may be a video networking terminal or an internet terminal. The conference control software can send the information of the invited terminals to the corresponding server, then the corresponding server generates a conference invitation signaling according to the information, and sends the conference invitation signaling to each invited terminal. And after the invited terminal accepts the invitation, the invited terminal can join the video conference of the video network.
In the embodiment of the invention, the terminals participating in the video networking video conference can comprise video networking terminals and internet terminals. Therefore, when a video conference is performed, the terminal that makes a speech may be a video terminal or an internet terminal. Which will be separately described below.
If the terminal performing speaking is an internet terminal, and the internet terminal is used as a source internet terminal, the source internet terminal collects first speaking data of the user, wherein the first speaking data may include audio data or video data. The source internet terminal may encode the first utterance data and encapsulate the first utterance data based on an internet protocol, which may obtain a first internet protocol data packet. The source internet terminal may send the first internet protocol data packet, that is, the first utterance data encapsulated based on the internet protocol, to the virtual terminal bound to the source internet terminal through the internet.
If the virtual terminal receives the first language data sent by the source internet terminal bound with the virtual terminal, the first language data can be correspondingly processed and then sent to other terminals participating in the video networking video conference.
If other terminals participating in the conference are video networking terminals which are used as target video networking terminals, the target video networking terminals cannot directly process the data sent by the source internet terminals because the source internet terminals process the related data based on the internet protocol and the target video networking terminals process the related data based on the video networking protocol.
Therefore, the virtual terminal performs the first protocol conversion on the first speech data to obtain the second speech data. In practical implementation, the virtual terminal converts the first speech data encapsulated based on the internet protocol into the second speech data encapsulated based on the video networking protocol. Specifically, the virtual terminal decapsulates first utterance data encapsulated based on an internet protocol, that is, the first internet protocol data packet, to obtain unencapsulated first utterance data, and encapsulates the first utterance data based on a video networking protocol to obtain a first video networking protocol data packet, that is, second utterance data encapsulated based on the video networking protocol.
If the other terminals participating in the conference are internet terminals and the internet terminal is a target internet terminal, the virtual terminal does not need to perform protocol conversion on the first utterance data because the source internet terminal and the target internet terminal process related data based on internet protocols. Therefore, the virtual terminal bound with the source internet terminal can forward the first utterance data to the virtual terminal bound with the target internet terminal, and then the virtual terminal bound with the target internet terminal forwards the first utterance data to the target internet terminal. And after receiving the first utterance data packaged based on the internet protocol, namely the first internet protocol data packet, the target internet terminal decapsulates the first internet protocol data packet to obtain the first utterance data which is not packaged, and decodes and plays the first utterance data.
If the other terminals participating in the conference are video network terminals which are used as target video network terminals, the virtual terminal can send the second speech data to the target video network terminals through the video network server after performing protocol conversion on the first speech data to obtain the second speech data. And after the target video networking terminal receives second speech data packaged based on the video networking protocol, namely the first video networking protocol data packet, the target video networking terminal decapsulates the first video networking protocol data packet to obtain second speech data which is not packaged, and decodes and plays the second speech data.
In specific implementation, the virtual terminal sends the second speech data encapsulated based on the video networking protocol to the video networking server through the video networking, and then the video networking server sends the second speech data to the target video networking terminal through the video networking.
In a preferred embodiment, the video network server may send the second speech data encapsulated based on the video network protocol to the video network terminal according to a 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.
Namely, the communication method in the video network includes:
and the master control server configures the downlink communication link of the current service.
And transmitting the data packet of the current service sent by the source terminal (virtual terminal) to a target terminal (such as a target video network terminal) according to the downlink communication link.
In the embodiment of the present invention, configuring the downlink communication link of the current service includes: and informing the switching equipment related to the downlink communication link of the current service to allocate the 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 main 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.
If the terminal performing speaking is a video network terminal, and the video network terminal is used as a source video network terminal, the source video network terminal collects third speaking data of the user, and the third speaking data may include audio data or video data. The source video networking terminal may encode the third speech data, and encapsulate the third speech data based on the video networking protocol, so as to obtain a second video networking protocol data packet. The source video networking terminal can send the second video networking protocol data packet, namely the third speech data based on the video networking protocol encapsulation, to the video networking server connected with the source video networking terminal through the video networking.
If the video network server receives the third speech data sent by the source video network terminal, the third speech data can be correspondingly processed and then sent to other terminals participating in the video network video conference.
If the other terminals participating in the conference are internet terminals which are target internet terminals, the target internet terminals cannot directly process the data transmitted by the source video networking terminal because the source video networking terminal processes the related data based on the video networking protocol and the target internet terminals process the related data based on the internet protocol.
Therefore, the video network server may first send the third speech data to the virtual terminal bound to the target internet terminal. In a preferred embodiment, the video networking server may send the third speech data encapsulated based on the video networking protocol to the virtual terminal bound to the target internet terminal according to the configured downlink communication link for the virtual terminal bound to the target internet terminal. And the virtual terminal performs second protocol conversion on the third speech data to obtain fourth speech data. In practical implementation, the virtual terminal converts the third speech data encapsulated based on the video networking protocol into the fourth speech data encapsulated based on the internet protocol. Specifically, the virtual terminal decapsulates third speech data encapsulated based on the video networking protocol, that is, the second video networking protocol data packet, to obtain unencapsulated third speech data, and encapsulates the third speech data based on the internet protocol to obtain a second internet protocol data packet, that is, fourth speech data encapsulated based on the internet protocol.
If the other terminals participating in the conference are video networking terminals and the video networking terminal is used as a target video networking terminal, the video networking server does not need to perform protocol conversion on the third speech data because the source video networking terminal and the target video networking terminal process related data based on a video networking protocol. Therefore, the video network server connected with the source video network terminal can forward the third speech data to the target video network terminal. And after the target video networking terminal receives the third speech data packaged based on the video networking protocol, namely the second video networking protocol data packet, the target video networking terminal decapsulates the second video networking protocol data packet to obtain the third speech data which is not packaged, and decodes and plays the third speech data.
And step 504, the virtual terminal sends the fourth speech data to a target internet terminal bound with the fourth speech data.
If the other terminals participating in the conference are internet terminals and the internet terminals serve as target internet terminals, the virtual terminal may send the fourth speech data to the target internet terminal bound with the virtual terminal after performing protocol conversion on the third speech data to obtain the fourth speech data. And after the target internet terminal receives the second speech data which is encapsulated based on the internet protocol, namely the second internet protocol data packet, decapsulating the second internet protocol data packet to obtain fourth speech data which is not encapsulated, and decoding and playing the fourth speech data.
In practical applications, it is considered that there may be users of multiple terminals speaking in a video-networking video conference, and therefore, in this case, the speaking data may be mixed before being transmitted to other terminals participating in the video-networking video conference.
For example, before the video network server sends the relevant speech data, such as the second speech data, to the target video network terminal, if it is detected that the second speech data includes multiple audio data, the multiple audio data in the second speech data are mixed, and then the mixed audio data are sent to the target video network terminal.
For another example, before the virtual terminal sends the related speech data, such as the third speech data, to the target internet terminal, if it is detected that the third speech data includes multiple channels of audio data, the multiple channels of audio data in the third speech data are subjected to audio mixing processing, and after the audio mixing processing, the third speech data is subjected to second protocol conversion to obtain fourth speech data, and the fourth speech data is sent to the target internet terminal.
Mixing (Audio Mixing), often also abbreviated as MIX, is the integration of multiple sources of sound into one Stereo (Stereo) or Mono (Mono) soundtrack. These original sound signals, which may originate from different musical instruments, voices or orchestras, respectively, are recorded from live performances or recording rooms. In the process of sound mixing, the frequency, dynamics, tone quality, positioning, reverberation and sound field of each original sound signal are independently adjusted to optimize each sound track, and then the sound tracks are superposed on a final finished product.
The mixing process may be performed by a synthesizer, a sound effect processor, a mixing base, or other devices, or may be performed by mixing software, such as GoldWave software. For a specific mixing process, a person skilled in the art may perform related processing according to actual experience, and the embodiment of the present invention is not discussed in detail herein.
In the embodiment of the invention, the virtual terminal can simulate the function of the real video network terminal, so that the data of the internet terminal can be sent to the video network terminal and the data of the video network terminal can be sent to the internet terminal, the internet terminal can also participate in the video network video conference, the communication range of the video network conference is expanded, and the user requirements can be better met.
