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 |
wherein:
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:
| 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, when receiving an information loading request of a user for monitoring resources, a resource server acquires corresponding resource main information according to resource authority of the user and sends the resource main information to a video network monitoring client, and the video network monitoring client loads the resource main information into a resource list.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for loading a monitoring resource list according to the present invention is shown, where the method may be applied in a video network, and specifically may include the following steps:
The video network monitoring client can be a browser and is used for displaying information of corresponding monitoring resources according to resource permissions of users. The video networking monitoring equipment can be a camera and is used for collecting monitoring data, transmitting the monitoring data to the protocol conversion server based on stream transmission, receiving an instruction sent by the protocol conversion server and executing the instruction. The cooperation server is used for managing the video networking monitoring equipment. The resource server is used for realizing the service of the monitoring resources, and comprises the steps of storing the resource information into the database, acquiring the corresponding resource information from the database according to the request of the video network monitoring client and returning the resource information to the video network monitoring client.
After a user logs in the video network monitoring client, the video network monitoring client acquires a user identifier of the user, generates an information loading request comprising the user identifier, and sends the information loading request to the resource server.
The resource main information is attribute information of the monitoring resource, and is information frequently used by the monitoring resource, namely, the frequency of display is high, and the data space occupied by the information is small. The resource main information may include a unique identifier of the monitoring resource, a device name, a transfer number, a monitoring number, longitude and latitude information, and an online state of the device, and in addition to these information, the resource main information may also include other commonly used attribute information of the monitoring resource, such as whether there is a video or not. There are about 20 kinds of attribute information in the resource master information. The protocol conversion server is a protocol conversion server and can convert streaming data into video networking protocol data or convert the video networking protocol data into streaming data. The monitoring number is a channel number of the video networking monitoring equipment connected to the protocol conversion server. The longitude and latitude information is the position information of the video network monitoring equipment. The device online status includes online or offline.
