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 datagram is a variety of protocol packets, and 32 + 1024 = 1056 bytes if the type of 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., 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 characteristics of the video network, one of the core concepts of the embodiment of the invention is provided, the video network conference management server collects the network management data of each area according to the protocol of the video network, and the video network synchronization server obtains the network management collected data from the video network conference management server and generates the address book data (address book directory data and address book terminal data) of the full video network according to the network management collected data. The display terminal acquires address list data of the full video network from the video network synchronization server, selects a target terminal from the address list data, and then locally displays audio and video data of the target terminal.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for displaying audio/video data according to the present invention is shown, where the method may be applied to a video network, and the video network may include a video network node server, a video network conference management server, a video network synchronization server, and a video network terminal, where the video network conference management server communicates with a plurality of video network node servers belonging to different areas, and the video network synchronization server communicates with the video network conference management server and the video network terminal, respectively, and the method specifically may include the following steps:
In the embodiment of the invention, the video networking conference management server (video networking conference management system) can communicate with a plurality of video networking node servers (video networking network management systems) in different areas. The node servers of the video network in each area are used for managing network management data of the video network terminals in each area, such as directory names and directory structures of the address book terminals, configuration information and address information of the address book terminals, and the like.
In the embodiment of the invention, on one hand, the node servers of the video networking in each area can actively upload the network management data of each area, and particularly, the node servers of the video networking can upload the network management data to the conference management server of the video networking according to the preset period. On the other hand, the video network conference management server can actively ask for network management data from the video network node servers of each region, and specifically, the video network conference management server asks for the network management data from the video network node servers of each region according to a preset period. After the video networking conference management server obtains the network management data of each region, the network management data can be summarized to obtain network management summarized data. Specifically, the video networking conference management server may perform deduplication processing on the obtained network management data, that is, the video networking conference management server may have the same address book data of the address book terminal in the network management data obtained from the video networking node servers in each area, and the video networking conference management server needs to delete the repeated network management data and only keep one unique network management data. The video networking conference management server can also perform hierarchical processing on the obtained network management data, that is, the video networking conference management server may have address book data of address book terminals with different levels and authorities in the network management data obtained from the video networking node servers in each area, and the video networking conference management server needs to perform hierarchical sequencing, classification and the like on the network management data.
In the embodiment of the invention, the video networking synchronous server can automatically acquire the summarized network management summarized data from the video networking conference management server according to the preset time period, and can also respond to the acquisition operation of a user and acquire the summarized network management summarized data from the video networking conference management server. The technical means adopted by the video networking synchronization server to obtain the network management summarized data is not particularly limited in the embodiment of the invention.
In a preferred embodiment of the present invention, the video networking synchronization server may obtain the network management summary data from the video networking conference management server according to the video networking protocol, where the network management summary data may be a compressed and encrypted data packet.
In the embodiment of the invention, when the synchronous server of the video network generates the address book directory data and the address book terminal data corresponding to the address book directory data according to the network management summary data, the synchronous server of the video network can generate the address book directory data according to the directory name and the directory structure of the address book terminal in the network management data of each area, and generate the address book terminal data according to the configuration information and the address information of the address book terminal in the network management data of each area. Specifically, the video networking synchronization server may use a directory name and a directory structure of the address book terminal in the network management data as address book directory data, and use configuration information and address information of the address book terminal in the network management data as address book terminal data.
