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, and the mobile terminal transmits alarm data containing alarm position information and alarm image-text information to a first video network node server according to a protocol of the video network. The first video network node server stores the alarm image-text information, generates an access address of the alarm image-text information in the first video network node server, and sends the alarm position information and the access address to the second video network node server. And the second video network node server acquires the alarm image-text information by using the access address and displays the alarm position information and the alarm image-text information.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of an alarm data processing method according to the present invention is shown, where the method may be applied to the internet and a video network, the internet may include a mobile terminal, and the video network may include a first video network node server and a second video network node server, where the first video network node server communicates with the mobile terminal and the second video network node server, respectively, and the method may specifically include the following steps:
step 501, the first video network node server receives alarm data from the mobile terminal.
In the embodiment of the present invention, the mobile terminal may be a terminal device such as a smart phone and a tablet computer, and the mobile terminal may adopt an android operating system or an IOS operating system. The mobile terminal may be located at any position where monitoring and alarming are needed, such as a station, a square, a school, and the like. The mobile terminal may generate the alarm data under the condition that the safety pre-warning occurs at the location, and the alarm data may be generated by manual triggering of an operator of the mobile terminal, for example, the operator clicks an alarm button on the mobile terminal to generate the alarm data. The alarm data may also be generated by the mobile terminal itself, for example, if the mobile terminal detects that the temperature nearby is higher than a preset temperature threshold value by using its own sensor, the alarm data is generated. The embodiment of the present invention does not specifically limit the generation manner of the alarm data.
In the embodiment of the present invention, the alarm data generated by the mobile terminal may include alarm location information, that is, location information where an alarm occurs, which may be specific latitude and longitude information or rough range information. For example, the specific latitude and longitude information may be obtained by the positioning device of the mobile terminal, and the operator may perform secondary revision on the latitude and longitude information obtained by the mobile terminal. The alarm data generated by the mobile terminal can also contain alarm image-text information, and the alarm image-text information can comprise one or more of alarm image information, alarm audio-video information and alarm text information.
