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 characteristics of the video network, one of the core concepts of the embodiment of the invention is provided, the video network client stores monitoring information in advance according to a protocol of the video network, when target monitoring data needs to be obtained again, the target monitoring node information is obtained by positioning according to the pre-stored monitoring information and the monitoring directory information obtained from the video network node server, then the target monitoring data is obtained according to the target monitoring node information, and the target monitoring data is added into the video conference of the video network.
Referring to fig. 5, a flow chart of steps of an embodiment of a method for processing monitoring data according to the present invention is shown, and the method may be applied to a video network, and the video network may include: the system comprises a video networking client, a video networking node server and a video networking terminal, wherein the video networking node server is respectively communicated with the video networking client and the video networking terminal, and can manage the video networking terminal communicated with the video networking node server and access monitoring data of the video networking terminal; the video network terminal is used for collecting monitoring data; the method comprises the following steps that the video network client is used for acquiring monitoring data from a video network node server and carrying out related processing and application on the acquired monitoring data, and specifically comprises the following steps:
In the embodiment of the present invention, the video networking client may be used to manage the video networking video conference, for example, add a participant terminal and monitoring data to the video networking video conference. The node server of the video network can be a streaming media server of the video network, is used for managing the video network terminal communicated with the node server of the video network and accessing the monitoring data of the video network terminal. The video network terminal can be a monitoring terminal and is used for collecting monitoring data. The embodiment of the invention does not specifically limit the equipment, the functions and the like of the node server of the video networking and the terminal of the video networking.
In the embodiment of the invention, when the node server of the video network manages the video network terminals communicated with the node server of the video network and accesses the monitoring data of the video network terminals, the node server of the video network can distribute unique identification information for each video network terminal, and the video network terminals have the characteristic of regional level, so that the corresponding regional level can be determined according to the identification information of the video network terminals. The area level may be an administrative area level to which the geographical location where the video networking terminal is located belongs, and the like. For example, a certain node server J of the video network manages video network terminals communicating with the video network server J, each video network terminal collects monitoring data of its own location, and each video network terminal belongs to different regional levels, for example, video network terminals a1 and a2 belong to an administrative area a, video network terminal B1 belongs to an administrative area B, and video network terminals C1 and C2 belong to an administrative area C, wherein the administrative area a and the administrative area C are administrative areas of the same level, and the administrative area B is an administrative area next to the administrative area C. The node server J of the video network may construct a node directory tree according to the hierarchical relationship between administrative areas to which each video network terminal belongs, and the node directory tree may be represented by monitoring directory information. Specifically, the monitoring directory information may include identification information of each video network terminal, administrative area information to which the video network terminal belongs, and the like.
In a preferred embodiment of the present invention, the local database of the video networking client is used to store related information of the monitoring data that the video networking client has acquired, such as identification information of a source video networking terminal of the monitoring data, and the like. The client of the video network may obtain monitoring information in the local database, where the monitoring information includes node organization information of target monitoring data to be obtained in the node directory tree, for example, the monitoring information includes identification information of a source video network terminal of the target monitoring data to be obtained. After a certain target monitoring data is obtained for the first time, the client of the video network can store the relevant information of the target monitoring data as monitoring information in the local database. In practical application, a user can check each node in the node directory tree step by step through the video network client side until a target monitoring terminal is selected. The video network client-side can respond to the step-by-step checking operation of the user, and the identification information of each level of nodes of the branch structure to which the target monitoring terminal belongs is stored according to the sequence of the regional levels to obtain the monitoring information.
In the embodiment of the invention, the source video network terminal of the target monitoring data to be acquired is generally a video network terminal at a lower layer in the node directory tree or a video network terminal with a lower area level. The video network client can restore the branch structure of the source video network terminal according to the identification information of the source video network terminal of the target monitoring data and the node directory tree. In practical application, the video network client may generate a root node, a group node, and a leaf node corresponding to the target monitoring data in the node directory tree according to the node organization information, where the child node is a node where the source video network terminal is located, the group node is a previous-level node of the leaf node, and the root node is a highest-level node of a branch structure to which the source video network terminal belongs. And the video network client determines the identification information of the root node, the group node and the leaf node corresponding to the target monitoring data as target monitoring node information.
After the video networking client side obtains the target monitoring node information, the target monitoring data are obtained from the video networking node server by using the target monitoring node information, and then the obtained target monitoring data are added into the video networking video conference. The video network node server receives target monitoring node information sent by the video network client, and can sequentially determine a source video network terminal step by step according to identification information of a root node, a group node and a leaf node in the target monitoring node information, and receive target monitoring data from the source video network terminal. For example, the identification information of the root node is "001", the identification information of the group node is "0013", and the identification information of the leaf node is "00132". The node server of the video network firstly determines a root node 'administrative region A' according to the identification information '001' of the root node, then determines a group node 'administrative region D' according to the identification information '0013' of the group node in the root node 'administrative region A', then determines a leaf node 'monitoring terminal e' according to the identification information '00132' of the leaf node in the group node 'administrative region D', and finally, the node server of the video network receives monitoring data from the 'monitoring terminal e' and returns the monitoring data to the client of the video network as target monitoring data.
After the video networking client acquires the target monitoring data, the target monitoring data can be subjected to related processing or application, for example, the target monitoring data is displayed on the video networking client, or the target monitoring data is added to the video networking video conference for being watched by a participant terminal in the video networking video conference.
Based on the above-mentioned related description of the embodiment of the method for processing monitoring data, a method for reversely positioning a directory tree is introduced below, which can be applied to the situation that a video conference on the internet needs to be frequently held, monitoring data of one or more monitoring terminals needs to be frequently added to the video conference on the internet, a user needs to acquire and select a target monitoring terminal from a plurality of protocol conversion servers, and the operation is complicated. As shown in fig. 6, after the user acquires and checks the target monitoring terminal for the first time, the relevant information of the target monitoring terminal is stored in the local database. In the subsequent video conference of the video network, if the monitoring data of the target monitoring terminal needs to be added to the video conference of the video network again, the monitoring resource root directory can be read from the protocol conversion server, and the relevant information of the target monitoring terminal can be read from the local database. The monitoring resource root directory comprises administrative region information to which each monitoring terminal belongs, wherein the administrative region information is key information of each node of a directory tree of a tree structure formed by the monitoring resource root directory. And performing recursive operation according to the monitoring resource root directory and the related information of the target monitoring terminal, and judging whether the target monitoring terminal is a node in the directory tree, wherein the node can be a root node, a group node or a leaf node.
