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 application: 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 networking, one of the core concepts of the embodiments of the present application is provided, following a protocol of the video networking, a middle component server is used to obtain a plurality of pieces of monitoring information from a database of an Mserver server, and the monitoring information is classified and encapsulated into a plurality of monitoring information data units based on gateway identifiers, each monitoring information data unit has a unit identifier corresponding to the gateway identifier, and when a data obtaining instruction is sent by the DRS server, the monitoring information data unit is sent to the DRS server. The monitoring information is processed and forwarded by the intermediate component server, so that the Mserver and the DRS server only need to execute sending and obtaining operations of the monitoring information, and do not need to additionally process the monitoring information, the workload of the Mserver and the DRS server is reduced, and the working efficiency of respectively processing normal services is improved.

In step 606, the intermediate component server 506 extracts, in view of the data acquisition instruction, a target monitoring information data unit corresponding to the target unit identifier from the second monitoring information data units, and sends the target monitoring information data unit to the DRS server 505.
After the DRS server 505 receives the second monitoring information data unit, since the second monitoring information data unit is of a JSON type, the second monitoring information data unit can be quickly restored to the monitoring information of the original format, for example, the monitoring information of the original format is XML type information, and then the DRS server 505 can restore the second monitoring information data to the monitoring information of the XML type.
The detailed description of step 6032 only needs to refer to the related description of step 502 in the first embodiment, which is not described again in this embodiment of the present invention.
