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 |
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 a variety of protocol packets, or is 1056 bytes if the type of the datagram is a unicast packet, but 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 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 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 proposed, in which, following a protocol of the video network, the first video network node server sends the first request message to the third video network node server through the second video network node server to obtain the packet information of the virtual terminal managed by the third video network node server. After the first video network node server determines the target virtual terminal from the grouping information, the second video network node server sends a second request message to a third video network node server so as to acquire the video network number of the target virtual terminal. And the first video network node server adds the target virtual terminal to the video conference according to the video network number of the target virtual terminal.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for processing a video conference according to the present invention is shown, where the method may be applied to an internet of view, and the internet of view may include a first internet of view node server, a second internet of view node server, and a third internet of view node server, where the second internet of view node server communicates with the first internet of view node server and the third internet of view node server, respectively, and the third internet of view node server is configured to manage one or more virtual terminals, and the method may specifically include the following steps:
In the embodiment of the present invention, the first node server of the video networking may be a video networking conference management server, which is used for managing the video conference, such as adding a participant terminal, and the like. The first video network node server can be provided with a conference scheduling module, and the conference scheduling module can realize functional interaction between video conference service and the second video network node server. The first video network node server can utilize the conference scheduling module to generate a first request message, and the first request message is used for acquiring the grouping information of the virtual terminals managed by the third video network node server.
