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), and is defined to be 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., more than 2 connections between a node switch and a node server, between a node switch and a node switch, and between 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 as follows: 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 of a data transmission method according to an embodiment of the present invention is shown, where the method is applied to a video network, and specifically includes the following steps:
step 501: receiving an identity reading instruction sent by a first video network terminal, wherein the identity reading instruction comprises: the terminal number or the video networking number of the second video networking terminal;
in this step, a party (for example, a first video network terminal) who wants to obtain identity data information (for example, identity card information, etc.) sends an identity reading instruction (which may also be an identity reading request, etc.) to a video network server through a video network protocol, that is, the video network server receives the identity reading instruction sent by the first video network terminal, where the identity reading instruction is used to request an instruction for reading the identity data information, where the instruction includes which terminal (for example, a second video network terminal) needs to be used to read the identity data information), that is, includes a terminal number of the second video network terminal or a video network number. It should be noted that, in the video network, the terminal number or the video network number is a unique identifier for identifying the video network terminal.
Step 502: sending the identity reading instruction to the second video network terminal so that the second video network terminal can read identity data information through an identity card reader;
in the step, after receiving the identity reading instruction, the video network server can directly send the identity reading instruction to the second video network terminal through a video network protocol; the identity reading instruction can also be firstly analyzed to obtain a terminal number or a video networking number of the second video networking terminal, then the identity reading instruction is sent to the second video networking terminal corresponding to the second video networking terminal number or the video networking number through a video networking protocol, namely, a video networking channel between the first video networking terminal and the second video networking terminal is established, and when the second video networking terminal receives the identity reading instruction, the identity data information is read through an identity card reader, and the read identity data information is packaged and then sent to a video networking server through the established video networking channel.
Step 503: and receiving the identity data information sent by the second video network terminal through a video network protocol.
In this step, the second video network terminal sends the identity data information to the video network server through the established video network channel, that is, the video network server receives the identity data information which is sent and encapsulated by the second video network terminal through the video network protocol.
Step 504: and sending the identity data information to the first video network terminal.
In the step, the video network server sends the identity data information to the first video network terminal through the established video network channel.
In the embodiment of the invention, when receiving an identity reading instruction sent by a first video network terminal, a video network server sends the identity reading instruction to a second video network terminal so that the second video network terminal can read identity data information through an identity card reader; and when receiving the identity data information which is read by the second video network terminal and sent by the video network protocol, sending the identity data information to the first video network terminal. That is to say, in the embodiment of the present invention, based on the video networking environment, the identity data information read by the identity card reader can be transmitted between the video networking terminals, which not only improves the transmission efficiency, reduces the consumption of transmission resources, but also improves the performance of the video networking terminals and the user satisfaction.
Optionally, in another embodiment, on the basis of the foregoing embodiment, before sending the identity reading instruction to the second internet of things terminal, the method may further include:
detecting whether the second video network terminal is in an online state or not; and if the terminal is in an online state, the step of sending the identity reading instruction to the second video network terminal is executed.
That is to say, in this embodiment, the internet of view server may periodically detect whether the second internet of view terminal is in an online state, and a specific detection manner may be detected by a heartbeat. That is to say, the second video network terminal can send a heartbeat to the video network server periodically to inform the video network server that the video network server is in an online state; and if the video network server does not receive the heartbeat sent by the second video network terminal within the preset time, the second video network terminal is in an offline state. Further, if the second video network terminal is in an offline state, the video network server cannot send the identity reading instruction to the second video network server, and the identity data reading fails, that is, when the second video network terminal is in an online state, the first video network terminal can read the identity data through the identity card reader of the second video network terminal, so that the identity data information read by the identity card reader can be directly transmitted between the video network terminals, the transmission efficiency is improved, the consumption of transmission resources is reduced, and the performance of the video network terminals and the user satisfaction are improved.
Referring to fig. 6, another flowchart of a data transmission method according to an embodiment of the present invention is shown, where the method is applied to a video network, and specifically includes the following steps:
step 601: the second video network terminal receives an identity reading instruction sent by the video network server, wherein the identity reading instruction is sent by the first video network terminal;
in the step, after receiving an identity reading instruction sent by a first video network terminal, the video network server includes a terminal number of a second video network terminal or a video network number, and then sends the identity reading instruction to the second video network terminal.
Step 602: the second video network terminal sends the identity reading instruction to an identity card reader;
in this step, when the second video network terminal receives the identity readable instruction, it needs to read the identity data information through the identity card reader, for example, read the identity card information of the identity card on the identity card reader, and certainly, may also read the account book or passport information. And then, the read identity data information is sent to a second video network terminal through the video network.
It should be noted that the identity card reader may be an identity card reader, a house number card reader, or a passport card reader, or an integration of all of the above, i.e. a smart identity card reader, etc.
