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 above characteristics of the video network, one of the core concepts of the embodiments of the present invention is proposed, where a storage management server receives a data access request carrying a first identifier, and obtains, in response to the data access request, a second identifier corresponding to the first identifier in the video network from a preset configuration database, according to a protocol of the video network.

Referring to FIG. 5, one of the steps of a data acquisition method embodiment of the present invention is shown in a flow chart. The method is applied to the video network, the video network comprises a storage management server, a target video network disk and a disk server corresponding to the video network disk, and the method comprises the following steps:

step 501, the storage management server receives a data access request carrying a first identifier; the first identification is the identification of the target video networking disk.

In the embodiment of the invention, the storage management server belongs to a video network storage management system, and the video network storage management system is used for managing a plurality of network disk servers and a plurality of video network disks in the video network. The video networking disk is a storage space which is allocated to individual or unit users in the video networking and is used for storing video files, text files and the like, the users of the video networking disk are distributed in all cities throughout the country, and servers, namely network disk servers, for managing the video networking disk of each province or each city are arranged in each province and each city of the country in the video networking.

A storage management system can simultaneously manage a plurality of network disk servers, each network disk server corresponds to a plurality of video network disks, and the network disk servers provide background storage and service functions of data for the plurality of video network disks. That is, one video network disk corresponds to a unique disk server, and one disk server corresponds to a plurality of video network disks. Each network disk server has a unique service database, and the service database stores the information of all video network disk users in the province or the city and the data information in the user network disk. The invention particularly provides a scheme for meeting the requirements of acquiring data of a plurality of video networking disks through a video network and quickly switching to a corresponding video networking disk through page clicking.

Firstly, a user initiates an access request aiming at a certain video network disk on a front-end page of a storage management system, the access request carries a first identifier of a target video network disk to be accessed, and a storage management server positioned at the rear end receives the access request. Wherein, the access request aiming at the target video network disk can comprise a query request of the user information of the target video network disk.

Step 502, the storage management server responds to the data access request, and acquires a second identifier corresponding to the first identifier in the video network from a preset configuration database; and the second identifier is the video network address identifier of the network disk server corresponding to the target video network disk.

In the embodiment of the invention, the preset configuration database is arranged in the storage management server, and the database stores the corresponding relation between a plurality of video network disks and the network disk server. Because one video network disk corresponds to a unique disk server and one disk server corresponds to a plurality of video network disks, the first identifier of the target video network disk corresponds to the second identifier of the unique disk server.

And according to the corresponding relation, obtaining a second identifier of the network disk server corresponding to the first identifier of the target video network disk to be accessed.

In the embodiment of the invention, due to the special architecture of the video network, the video network does not use an IP address to identify the terminal, but uses the MAC address of each terminal to identify the terminal. The terminals of the video network, such as a video network server, a network disk server, a storage management server and the like, which have uniqueness in MAC addresses in the video network, can be used for identifying the terminals of the video network. For ease of management, MAC addresses in the visual network are represented by corresponding identifications. Therefore, the second identifier is an identifier corresponding to the MAC address of the network disk server in the video network, and the configuration database stores a corresponding relationship between the first identifier and the second identifier, that is, a corresponding relationship between the first identifier and the identifier corresponding to the MAC address of the network disk server.

Step 503, the storage management server sends the access request to the network disk server corresponding to the second identifier.

In the embodiment of the present invention, the second identifier corresponds to a network disk server, and the data of the target video network disk to be accessed is stored in the network disk server, so that the target data of the target video network disk can be obtained from the network disk server corresponding to the second identifier. Therefore, the storage management server sends the access request to the network disk server corresponding to the second identifier.

And step 504, the network disk server acquires target data according to the data access request.

A service database is integrated on the network disk server, and the data of the target video network disk to be accessed is stored in the service database. The access request carries a first identifier of the target video network disk, and the service database stores data of the video network disk corresponding to the first identifier, so that the target video network disk can be accessed by accessing the service database, user data of the target video network disk is obtained according to an operation instruction carried by the access request, and the user data is returned to the storage management server.

Step 505, the storage management server receives the target data and returns the target data to the requester.

After receiving the target data sent by the network disk server, the storage management server returns the target data to the requester, and the requester is the front-end page of the storage management system, so that the user can obtain the target data.

In summary, in the embodiment of the present invention, the storage management server receives a data access request carrying a first identifier; the storage management server responds to the data access request and acquires a second identifier corresponding to the first identifier in the video network from a preset configuration database; the storage management server sends the access request to a network disk server corresponding to the second identifier; the network disk server acquires target data according to the data access request; and the storage management server receives the target data and returns the target data to the requester. In the method, the second identifier of the network disk server corresponding to the target video network disk can be obtained from the preset configuration database, so that the storage management server can obtain the target data from the network disk server through the second identifier, and when the video network disk is switched and accessed, the configuration file does not need to be reloaded, thereby improving the operation simplicity.

Referring to fig. 6, there is shown a second step flow diagram of an embodiment of a data acquisition method of the present invention. The method is applied to the video network, the video network comprises a storage management server, a target video network disk and a disk server corresponding to the target video network disk, and the method comprises the following steps:

601, the storage management server receives a data access request carrying a first identifier; the first identification is the identification of the target video networking disk.

In the embodiment of the present invention, step 601 may refer to step 501, which is not described herein again.

Step 602, the storage management server responds to the data access request, and obtains a second identifier corresponding to the first identifier in the video network from a preset configuration database; and the second identifier is the video network address identifier of the network disk server corresponding to the target video network disk.

In the embodiment of the present invention, step 602 may refer to step 502, which is not described herein again.

Step 603, the storage management server sends the data access request and the second identifier to the video network server, where the video network server is configured to send the data access request to a network disk server corresponding to the second identifier.

In the embodiment of the invention, the storage management server is in communication connection with a video network server in a video network. The storage management server receives the data access request and acquires the second identifier from the preset configuration database in step 601 and step 602, which are both performed in the internet. Because the data to be accessed is located in the network disk server and the network disk server is located in the video network, the data access request and the second identifier need to be sent to the video network server first. Specifically, the data access request and the second identifier may be both encapsulated in a data packet of an internet of view protocol, and sent to the internet of view server through a service transparent transmission instruction of the internet of view.

After receiving the data packet, the video networking server analyzes a second identifier from the data packet and locates a certain network disk server according to the second identifier.
