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:

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:

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, one of the core concepts of the embodiment of the invention is provided, in the process of executing the video network service, the video network terminal can execute the corresponding video network service based on the voice control instruction of the user, and then the user only needs to input the voice control instruction by voice without pressing keys to input the video network control instruction, so that the operation of the user is convenient.

In the embodiment of the invention, the video network is provided with a video network terminal, and the video network terminal can be a terminal which supports a video network protocol and can execute a video network service. For example, the video networking terminal may be a video networking conference terminal supporting a video networking protocol, and the video networking terminal may also be a video capture terminal supporting the video networking protocol, and the like, which are not specifically limited in the embodiment of the present invention.

Referring to fig. 5, a schematic diagram of a cooperative transformation server, a decompression relay terminal and an internet terminal according to the present invention is shown, where theinternet terminal 501 is a terminal that needs to synchronize video network resources. The internet terminal may support an internet protocol. Theprotocol conversion server 503 may be provided with two network cards, wherein one network card supports a video networking protocol, and one network card supports an internet protocol, so as to implement interconnection between the video networking and the internet, and the like. Thedecompression relay terminal 502 may support an internet protocol or a video networking protocol, and the like, and thedecompression relay terminal 502 may decompress a video networking resource compression packet, and the like. In the embodiment of the present invention, this is not particularly limited.

The cooperative server identifier may be a primary message number of the cooperative server, and the like, which is not specifically limited in the embodiment of the present invention.

For example, if theinternet terminal 501 needs to acquire the video network resource in the coordination server 1, if the coordination server identifier of the coordination server 1 is a, theinternet terminal 501 sends a video network resource synchronization request to thedecompression relay terminal 502, where the synchronization request includes the coordination server identifier a.

In the embodiment of the present invention, thecollaboration server 503 may store the compressed packets of the resources of the video networking.

In the embodiment of the invention, the protocol conversion server is provided with double network cards, wherein one network card supports a video networking protocol, and the other network card supports an internet protocol, so that interconnection and intercommunication between the video networking and the internet are realized. Here, the data interaction between thedecompression relay terminal 502 and the relay server may be based on a video networking protocol, an internet protocol, or the like. This is not particularly limited in the embodiments of the present invention.

Step 604: after receiving the video network resource compression packets, decompressing the video network resource compression packets, and synchronizing the video network resource compression packets into a database; the database is used for receiving the video networking resource query request of the Internet terminal and returning video networking resources corresponding to the video networking resource query request to the Internet terminal.
