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.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a video networking conferencing method according to an embodiment of the present invention is shown, where the video networking includes a conference management platform, a streaming media server, and a video networking terminal, the video networking is communicatively connected to an ethernet, the ethernet includes a unified video platform, and the method specifically includes the following steps:
the conference opening instruction may be used to control the conference management platform to start a web conference.
In the embodiment of the invention, when a user needs to start a conference (conference teaching), a conference opening instruction can be sent to the conference management platform through the unified video platform.
As an example, in a telemedicine program, a classroom and operating room may be deployed while surgical teaching is performed. The operating room is a room in which doctors really perform operations, one or more camera devices are placed inside the operating room, the camera devices are used for shooting the whole process of the doctor performing the operations in real time and uploading the shot whole process to a conference management platform so as to be played in a classroom, and only output devices are arranged in the classroom and are provided for students to watch the doctors to perform the operations and study.
The unified video platform is a platform for maintaining and managing equipment in an operating room and a classroom, and can include functions of adding equipment, deleting equipment, updating equipment and the like.
The conference management platform is a video network-based terminal and can be used for scheduling conferences. The conference management platform may have a protocol conversion function, and may perform protocol conversion on the received data, for example, may convert data based on an ethernet protocol into data based on an internet protocol, or convert data based on the internet protocol into data based on the ethernet protocol.
In a preferred embodiment of the present invention, the ethernet further includes a streaming media management platform, and before the step 501, the method further includes the following sub-steps:
the unified video platform receives a meeting opening request sent by a user; the conference opening request carries a terminal identifier; the unified video platform sends a main message number acquisition request to the streaming media management platform according to the meeting request; the unified video platform receives a main message number returned by the streaming media management platform in response to the main message number acquisition request; and the unified video platform generates an opening instruction based on an Ethernet protocol by adopting the main message number and the terminal identification.
The terminal identification can be an identification code of the video network terminal and is used for uniquely identifying the corresponding video network terminal. Specifically, the terminal identifier may be composed of 5 digits, for example, the terminal identifier is: 11153.
the unified video platform can provide a conference setting interface on which a user can set the participant terminal, for example, add devices, delete devices, update devices, and the like. The conference setting interface can further comprise a confirmation button, and when a user clicks the confirmation button, the conference setting interface is equivalent to sending a conference opening request to the unified video platform. If the user sets the participant terminal before clicking the decision button, for example, the terminal identifier of the video network terminal is added, the conference opening request may carry the terminal identifier. In a specific implementation, the conference opening request may carry a plurality of terminal identifiers, that is, may have a plurality of participant terminals.
In the embodiment of the invention, when the unified video platform receives a meeting request sent by a user, a main message number acquisition request can be sent to the streaming media management platform. The streaming media management platform is a preset platform for managing and scheduling the streaming media server, and the primary message number is the unique identification code of the streaming media server.
After receiving the main message number acquisition request, the streaming media management platform may select a streaming media server that is relatively not busy in service, for example, a streaming media server with the least service among the multiple streaming media servers, determine the main message number of the streaming media server, and return the main message number of the streaming media server to the unified video platform. Therefore, the unified video platform can generate the conference opening instruction by adopting the main message number and the terminal identifier carried in the conference opening request.
Since the unified video platform is deployed in the ethernet and needs to transmit data through the ethernet protocol, the generated conference opening instruction may be a conference opening instruction based on the ethernet protocol.
In a preferred embodiment of the present invention, after the step 501, the following steps may be further included:
and the conference management platform converts the conference opening instruction based on the Ethernet protocol into a conference opening instruction based on a video networking protocol.
In the embodiment of the invention, after receiving the conference opening instruction based on the Ethernet protocol sent by the unified video platform, the conference management platform can convert the conference opening instruction into the conference opening instruction based on the video networking protocol so as to be convenient for transmission in the video networking.
in the embodiment of the invention, the conference management platform determines the target video network terminal and the target streaming media server according to the conference opening instruction.
In a preferred embodiment of the present invention, the conference opening instruction carries a terminal identifier of the video network terminal and a primary message number of the streaming server, and the step 502 may include the following sub-steps:
the conference management platform takes the video networking terminal corresponding to the terminal identification as a target video networking terminal according to the conference opening instruction; and the conference management platform takes the streaming media server corresponding to the main message number as a target streaming media server.
In the embodiment of the invention, the conference management platform can extract the terminal identification in the conference opening instruction, so that the video network terminal corresponding to the terminal identification is determined according to the terminal identification, and the video network terminal corresponding to the terminal identification is determined as the target video network terminal.
The conference management platform can also extract the main message number in the conference opening instruction, so as to determine the streaming media server corresponding to the main message number according to the main message number, and determine the streaming media server corresponding to the main message number as the target streaming media server.
