2. Video networking packet definition
2.1 Access network packet definition
The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.
As shown in the following table, the data packet of the access network mainly includes the following parts:
DA SA Reserved Payload CRC
wherein:
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;
the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);
the reserved byte consists of 2 bytes;
the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;
the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
DA SA Reserved label (R) Payload CRC
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
Based on the above characteristics of the video network, one of the core concepts of the embodiments of the present invention is provided, following the protocol of the video network, the video network server receives the request sent by the terminal initiating the forced call in the video network, and the video network server establishes a data interaction channel between the two terminals while forwarding the request to the terminal requiring the forced call, so as to realize that the terminal initiating the forced call in the video network forcibly makes a call with the terminal requiring the forced call.
Fig. 5 shows a flowchart of a method for controlling a terminal according to an embodiment of the present invention, where the method is applied to a video network including a first terminal, a video network server, and a second terminal, where the first terminal and the second terminal are any terminals in the video network, and the method for controlling the terminal includes the following steps:
step 501: the method comprises the following steps that a first terminal sends a forced call request to a video networking server, the forced call request is used for indicating the first terminal to request to carry out audio and video call with a second terminal in a forced mode, and the forced call request comprises the following steps: the video networking number of the first terminal and the video networking number of the second terminal.
In the embodiment of the invention, the video network comprises a plurality of terminals, users can use the terminals to use and operate related services of the video network, and the instruction and data interaction between the terminals needs to be processed and forwarded by a video network server. When a first terminal in a plurality of terminals needs to forcibly perform audio and video call with a second terminal in the plurality of terminals, a forced call request needs to be sent to a video networking server, the request is used for indicating the first terminal and the second terminal to forcibly perform the audio and video call, and the request comprises: the video networking number of the first terminal and the video networking number of the second terminal. When the request is received by the video network server, the subsequent operation can be carried out according to the request.
For example: the number of the first terminal video network in the video network is as follows: 86-999999, the second terminal video network number is: 01-444444, the first terminal needs to forcibly talk to the second terminal. The first terminal sends a forced call request to a video network server, wherein the request comprises: the number field, operation type field, wherein operation type field includes: setting information, wherein the setting information is information representing the operation type, wherein 1 represents that the operation type is forced conversation, and 0 represents that the operation type is forced conversation to be common conversation; then the forced call request includes: number field: 86-999999, 01-444444; operation type field: 1.
step 502: and the video networking server responds to the forced call request and establishes an audio and video data channel between the first terminal and the second terminal according to the video networking number of the first terminal and the video networking number of the second terminal.
In the embodiment of the invention, when a terminal in the video network performs data interaction, the video network server is required to provide a channel for data interaction, so that after the video network server receives a forced call request, the video network server is required to establish an audio/video data channel between a first terminal and a second terminal according to a video network number of the first terminal and a video network number of the second terminal in the request, the data channel is marked with channel information, the channel information represents what the channel is for which terminals, and the channel information also stores the forced call request sent by the first terminal.
For example: the forced call request received by the video networking server comprises the following steps: number field: 86-999999, 01-444444; operation type field: the video network server, according to the video network number in the request: 86-999999, 01-444444, and operation type 1: and forced conversation, namely establishing an audio and video data channel between the two terminals, and marking the data channel as the audio and video data channel for forced conversation between the 86-999999 terminal and the 01-444444 terminal.
Step 503: and the video network server forwards the forced call request to the second terminal.
In the embodiment of the invention, after the channel is established by the video network server, the video network server forwards the forced call request sent by the first terminal to the second terminal.
Step 504: and the second terminal responds to the forced call request and carries out audio and video call with the first terminal through the audio and video data channel.
In the embodiment of the invention, after the video networking server forwards the forced call request to the second terminal, the second terminal receives the request and responds to the request, and the request is used for forcibly enabling the second terminal to carry out audio and video data interaction with the first terminal so as to realize the forced audio and video call between the second terminal and the first terminal through the audio and video data channel.
For example: after an audio and video data channel for forced conversation between a 86-999999 terminal and a 01-444444 terminal is established by a video networking server, a forced conversation request sent by the 86-999999 terminal is forwarded to the 01-444444 terminal, after the 01-444444 terminal receives the request, the audio and video data of the 01-444444 terminal are transmitted to the 86-999999 terminal through the audio and video data channel without any permission or authentication or detection, and meanwhile, the 01-444444 terminal receives the audio and video data sent by the 86-999999 terminal through the audio and video data channel without any permission or authentication or detection.
Therefore, the audio and video conversation between any terminal and any other terminal in the video network is realized.
Optionally, in practical application, in order to prevent some users of the video networking from maliciously using the terminal to forcibly talk with other terminals, an authority level may be further set, and a terminal with a high-level authority may select whether to talk with a terminal with a low-level authority according to their own will, and based on this situation, after the video networking server forwards the forced talk request to the second terminal, the method for controlling the terminal further includes:
step X1: and the second terminal responds to the forced call request and sends a call rejection request to the video networking server, wherein the call rejection request is sent by the second terminal under the condition that the authority level of the second terminal is higher than that of the first terminal.
In the embodiment of the invention, after receiving the forced call request sent by the video networking server, the second terminal firstly judges the relationship between the authority level of the second terminal and the authority level of the first terminal. And if the authority level of the second terminal is higher than that of the first terminal, the second terminal can choose to refuse to forcibly talk with the first terminal, and in the case of rejection of the second terminal, the second terminal sends a request for refusing the talk to the video network server.
For example: the authority level of a first terminal 86-999999 in the video network is 2, the authority level of a second terminal 01-444444 in the video network is 0, after an audio and video data channel for forced conversation between the 86-999999 terminal and a 01-444444 terminal is established by a video network server, a forced conversation request is forwarded to the 01-444444 terminal, after the 01-444444 terminal receives the request, the authority level of the 01-444444 terminal is judged to be higher than that of the 86-999999 terminal, the 01-444444 terminal refuses to conduct audio and video conversation with the 86-99999999 terminal, and then the 01-444444 terminal sends the refusing conversation request to the video network server.
Step X2: and the video networking server responds to the call rejection request, closes the audio and video data channel and forwards the call rejection request to the first terminal.
In the embodiment of the invention, the video networking server receives the call rejection request sent by the second terminal, responds to the request, closes the established audio and video data channel between the first terminal and the second terminal, and forwards the call rejection request to the first terminal. After receiving the call rejection request, the first terminal displays the call rejection information on a display interface of the first terminal.
For example: the second terminal 01-444444 refuses to carry out audio and video conversation with the first terminal 86-999999 in the video network, the 01-444444 terminal sends a conversation refusing request to the video network server, the video network server responds to the conversation refusing request, forwards the conversation refusing request to the 86-999999 terminal, and closes an established audio and video data channel between the 86-999999 terminal and the 01-444444 terminal. And after the 86-999999 terminal receives the call rejection request, the information of call rejection is displayed on a display interface of the terminal.
It can be understood that if the second terminal agrees to perform audio and video communication with the first terminal under the condition that the authority level of the second terminal is higher than that of the first terminal, the second terminal responds to the forced communication request and performs audio and video data interaction with the first terminal, that is, the second terminal performs audio and video communication with the first terminal.
Under the condition that the self authority level of the second terminal is higher than that of the first terminal, after the second terminal agrees to carry out audio and video conversation with the first terminal, the second terminal and the first terminal start to carry out audio and video conversation, and the second terminal can actively stop the audio and video conversation with the first terminal, and the method comprises the following steps:
step Y1: and the call stopping request is sent by the second terminal to the video networking server, and is sent by the second terminal under the condition that the authority level of the second terminal is higher than that of the first terminal.
Step Y2: and the video networking server responds to the call stopping request, closes the audio and video data channel and forwards the call stopping request to the first terminal.
In the embodiment of the invention, under the condition that the self authority level of the second terminal is higher than that of the first terminal, the second terminal and the first terminal start audio and video communication, then the second terminal wants to actively stop the audio and video communication with the first terminal, the second terminal sends a communication stopping request to the video networking server, and after receiving the request, the video networking server responds to the request, forwards the communication stopping request to the first terminal and closes the established audio and video data channel between the first terminal and the second terminal. After receiving the call stopping request, the first terminal displays the call stopping information on a display interface of the first terminal.
For example: the second terminal 01-444444 and the first terminal 86-999999 in the video network carry out audio and video conversation, the 01-444444 terminal needs to stop the audio and video conversation with the 86-999999 terminal, the 01-444444 terminal sends a conversation stopping request to the video network server, the video network server responds to the conversation stopping request, forwards the conversation stopping request to the 86-9999 terminal, and closes the established audio and video data channel between the 86-999999 terminal and the 01-444444 terminal. After receiving the call stop request, the 86-999999 terminal displays the call stop information on its own display interface.
It can be understood that, because the forced call is initiated by the first terminal, even if the permission level of the first terminal is lower than that of the second terminal, the first terminal can still actively stop the audio/video call with the second terminal, and the implementation method of the forced call is the same as the method for stopping the audio/video call with the first terminal by the second terminal, and is not described herein again.
Similarly, if the forced call is initiated by the first terminal. And the authority level of the first terminal is higher than the second authority, so that only the first terminal can actively stop the audio and video call after the audio and video call is carried out between the first terminal and the second terminal, and the second terminal cannot actively stop.
If the second terminal judges that the authority level of the second terminal is lower than that of the first terminal, the steps are as follows:
step X3: the second terminal responds to the forced call request and sends own audio and video data to the video network server, and the audio and video data of the second terminal are forcibly sent by the second terminal under the condition that the authority level of the second terminal is lower than that of the first terminal;
step X4: the video networking server receives the audio and video data sent by the second terminal, transmits the audio and video data of the second terminal to the first terminal through the audio and video data channel, and transmits the audio and video data of the first terminal to the second terminal through the audio and video data channel.
In the embodiment of the invention, after receiving the forced call request sent by the video networking server, the second terminal firstly judges the relationship between the authority level of the second terminal and the authority level of the first terminal. And if the permission level of the second terminal is lower than that of the first terminal, the second terminal responds to the forced call request, actively sends the audio and video data of the second terminal to the first terminal through the audio and video data channel, and receives the audio and video data of the first terminal through the audio and video data channel.
For example: the authority level of a first terminal 86-999999 in the video network is 1, the authority level of a second terminal 01-444444 in the video network is 3, after an audio and video data channel for forced conversation between a 86-999999 terminal and a 01-444444 terminal is established by a video network server, a forced conversation request is forwarded to the 01-444444 terminal, after the 01-444444 terminal receives the request, the authority level of the 01-444444 terminal is judged to be lower than that of the 86-999999 terminal, the 01-444444 terminal responds to the forced conversation request, and actively sends own audio and video data to the 86-9999999999 terminal through the audio and video data channel, and meanwhile receives the audio and video data of the 86-9999 terminal through the audio and video data channel.
Optionally, the forced call request further includes: channel information of the audio and video data channel; after step 504, the method for controlling a terminal further includes:
step 505: and the video network server keeps the audio and video data channel under the condition of determining that the second terminal is abnormally offline.
In the embodiment of the invention, in the process of audio and video conversation between the second terminal and the first terminal through the audio and video data channel, if the second terminal does not send a conversation stopping request, the audio and video data interaction with the first terminal is suddenly interrupted, the abnormal offline of the second terminal is judged, and the video network server keeps the preset time length of the audio and video data channel under the condition of determining the abnormal offline of the second terminal, so that the audio and video conversation can be automatically reconnected to continue to be carried out with the first terminal under the condition that the second terminal is recovered to be normal. And if the second terminal does not recover to be normal after the preset duration, the audio and video data channel is cancelled, and the first terminal needs to initiate a forced call request to the second terminal again.
For example: the video networking server establishes an audio and video data channel between a 86-999999 terminal and a 01-444444 terminal, the 86-999999 terminal and a 01-444444 terminal carry out audio and video conversation, in the process, the 01-444444 terminal does not send a conversation stopping request, the audio and video conversation with the 86-999999 terminal is suddenly interrupted, the video networking server determines that the 01-444444 terminal is abnormally off-line in the audio and video conversation process with the 86-999999 terminal, and the video networking server continues to keep the audio and video data channel between the 86-999999 terminal and the 01-444444 terminal for 5 minutes if the preset time is 5 minutes.
Step 506: and the video network server forwards the forced call request to the second terminal according to the channel information under the condition of determining that the second terminal is recovered to be connected.
In the embodiment of the invention, because the audio and video data channel is marked with the channel information after being established, the video network server sends a forced call request to the second terminal according to the channel information under the condition that the video network server determines that the second terminal is recovered to be connected, so that the second terminal is forced to carry out audio and video call with the first terminal through the audio and video data channel.
For example: the video network server establishes an audio and video data channel between the 86-999999 terminal and the 01-444444 terminal, the data channel is marked as an audio and video data channel for forced conversation between the 86-999999 terminal and the 01-444444 terminal, and the forced conversation request is sent by the 86-999999 terminal and stored in channel information. After the 01-444444 terminal suddenly goes off-line abnormally, the video network server determines that the 01-444444 terminal goes off-line abnormally in the process of audio-video communication with the 86-999999 terminal, and the video network server continues to keep the audio-video data channels of the 86-999999 terminal and the 01-444444 terminal for 5 minutes. And in 5 minutes, when the video network server determines that the 01-444444 terminal is recovered to be connected, the video network server sends a forced call request to the 01-444444 terminal according to the channel information of the audio and video data channels of the 86-999999 terminal and the 01-444444 terminal, so that the 01-444444 terminal can carry out audio and video call with the 86-999999 terminal through the audio and video data channels. If the video network server determines that the 01-444444 terminal is not recovered after 5 minutes, the video network server logs out the audio and video data channels of the 86-999999 terminal and the 01-444444 terminal, and then the 86-999999 terminal wants to have a forced call with the 01-444444 terminal and needs to send a forced call request to the 01-444444 terminal again.
In summary, assume that the number of the first terminal in the video network is: 86-999999, the second terminal video network number is: 01-444444, the first terminal authority level is 2, the second terminal authority level is 0, the first terminal needs to compulsorily communicate with the second terminal.
The method comprises the following steps that a first terminal sends a forced call request to a video networking server, wherein the forced call request comprises: number field: 86-999999, 01-444444; operation type field: 1; permission field: 2. the video network server receives the forced call request, and according to the video network number in the request: 86-999999, 01-444444, and operation type 1: and forced conversation, namely establishing an audio and video data channel between the two terminals, storing the forced conversation request sent by the 86-999999 terminal in channel information, and marking the data channel as the audio and video data channel for forced conversation between the 86-999999 terminal and the 01-444444 terminal.
After an audio and video data channel for forced conversation between a 86-999999 terminal and a 01-444444 terminal is established by a video networking server, a forced conversation request is forwarded to the 01-444444 terminal, after the 01-444444 terminal receives the request, the authority level 0 of the 01-444444 terminal is judged to be higher than the authority level 2 of the 86-999999 terminal, and if the 01-444444 terminal refuses audio and video conversation with the 86-9999 terminal, the 01-444444 terminal sends a request for refusing conversation to the video networking server.
And the video network server responds to the call rejection request, forwards the call rejection request to the 86-999999 terminal, and closes the established audio-video data channel between the 86-999999 terminal and the 01-444444 terminal. And after the 86-999999 terminal receives the call rejection request, the information of call rejection is displayed on a display interface of the terminal.
Assuming that a second terminal 01-444444 in the video network agrees to carry out audio and video call with a 86-999999 terminal, the 01-444444 terminal actively sends audio and video data of the terminal to the 86-999999 terminal through an audio and video data channel in response to a forced call request, and simultaneously receives the audio and video data of the 86-9999 terminal through the audio and video data channel. And then the 01-444444 terminal needs to stop the audio and video call with the 86-999999 terminal, the 01-444444 terminal sends a call stop request to the video network server, the video network server responds to the call stop request, forwards the call stop request to the 86-999999 terminal, and closes the established audio and video data channel between the 86-999999 terminal and the 01-444444 terminal. After receiving the call stop request, the 86-999999 terminal displays the call stop information on its own display interface.
In the process of audio and video communication between the 86-999999 terminal and the 01-444444 terminal, the 01-444444 terminal is suddenly disconnected, at the moment, the video network server determines that the 01-444444 terminal is disconnected in the process of audio and video communication between the 86-999999 terminal and the 01-444444 terminal, and the video network server continues to maintain audio and video data channels between the 86-999999 terminal and the 01-444444 terminal. And when the video network server determines that the 01-444444 terminal is recovered to be connected, the video network server sends a forced call request to the 01-444444 terminal according to the channel information of the audio and video data channels of the 86-999999 terminal and the 01-444444 terminal, so that the 01-444444 terminal can carry out audio and video call with the 86-999999 terminal through the audio and video data channels.
