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 embodiments of the present invention is provided, and the protocol of the video network is followed, when the data of the video network is stored in the data center of the main video network, the data of the video network is also stored in the data center of the backup video network, so that when the data center of the main video network is down and the data service cannot be provided for the data server of the main video network by the data center of the main video network, the data service can be requested from the data center of the backup video network by the data center of the main video network, the data service can be provided for the data server of the main video network by the data center of the backup video network without waiting for the data center of the main video network to be restored, and thus the normal operation of the data service of the video network can be ensured.
Referring to FIG. 5, a block diagram of an embodiment of a data processing system based on the visual networking of the present invention is shown, the system comprising:
a main video network data center 01, a backup video network data center 02 and a main video network server 03;
the main video network data center 01 is used for collecting video network data and storing the video network data in the main video network data center 01 and the backup video network data center 02 respectively;
the main video network data center 01 can directly store video network data in the main video network data center 01, the main video network data center 01 can send the collected video network data to the backup video network data center 02, and the backup video network data center 02 receives the video network data and stores the video network data in the backup video network data center 02.
The main video network server 03 is used for sending an acquisition request for acquiring video network data to the main video network data center 01, and if video network data returned by the main video network data center 01 according to the acquisition request is not received within a first preset time after the acquisition request is sent, sending the acquisition request to the backup video network data center 02;
when the primary video networking server 03 needs to acquire video networking data, an acquisition request for acquiring the video networking data may be sent to the primary video networking data center 01, and the primary video networking data center 01 receives the acquisition request, acquires the stored video networking data from the primary video networking data center 01, and sends the video networking data to the primary video networking server 03.
However, when the primary networking data center 01 fails, the primary networking data center 01 cannot send the networking data to the primary networking server 03, for example, the primary networking data center 01 cannot receive the acquisition request, or the primary networking data center 01 can receive the acquisition request, but a storage device in the primary networking data center 01 fails, so that the primary networking data center 01 cannot access the storage device, and thus cannot acquire the networking data.
Therefore, the primary video network server 03 cannot receive the video network data after sending the data request to the primary video network data center 01, and in order to enable the primary video network server 03 to obtain the video network data, the primary video network server 03 can also send the acquisition request to the backup video network data center 02.
