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 byte, 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 (e.g. various protocol packets, multicast data packets, unicast data packets, etc.), there are at most 256 possibilities, 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 types of different datagrams, and is 64 bytes if the type of the datagram is various protocol packets, and 32+1024=1056 bytes if the type of the datagram is a unicast packet, although 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 a Label of Multi-Protocol Label switching (MPLS), and assuming that there are two connections between a device a and a device B, there are 2 labels for a packet from the device a to the device B, and 2 labels for a 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 0x0001. 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, which is located between the reserved bytes and the payload of the packet.
Based on the characteristics of the video network, one of the core concepts of the embodiment of the invention is provided, a fingerprint information acquisition request is sent to a video network switch in the video network through a client in the Ethernet according to a protocol of the video network, the video network switch informs a video network terminal to acquire fingerprint information of a user according to the fingerprint information acquisition request, the video network terminal sends the acquired fingerprint information to the video network switch and stores the fingerprint information in a preset storage position, the video network switch returns path information of the storage position to the client, and the client accesses the fingerprint information through the path information.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for accessing fingerprint information according to the present invention is shown, where the method may be applied to a video network, where the video network includes a video network switch and a video network terminal, the video network switch is connected to the video network terminal, and the video network switch communicates with a client in an ethernet network, and the method may specifically include the following steps:
in step 501, the video network switch receives a fingerprint information collection request from a client.
In the embodiment of the present invention, the video networking switch may be any network composition structure, such as a storage gateway, in the video networking, where the video networking switch has a communication function with a client in an ethernet network, and is connected to a video networking terminal in the video networking. In a specific implementation, the video network terminal may be a Set Top Box (STB), commonly referred to as a Set Top Box or Set Top Box, which is a device for connecting a tv Set and an external signal source, and may convert a compressed digital signal into tv content and display the tv content on the tv Set. Generally, the set-top box may be connected to a camera and a microphone for collecting multimedia data such as video data and audio data, and may also be connected to a television for playing multimedia data such as video data and audio data.
Furthermore, the communication between the video networking switch and the client may be performed through an ethernet protocol, for example, a hypertext transfer protocol, and the like. The video network switch and the video network terminal can communicate through a video network protocol, and the video network protocol can be regarded as a special protocol which is transmitted in the video network and is used for controlling equipment in the video network.
In this embodiment of the present invention, the client in the ethernet may be any terminal device, such as a personal computer, a mobile terminal, or a tablet computer, in the ethernet, which has a function of communicating with a video networking switch in the video networking.
