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 provided, and the data stored in the cloud may be bound to the user, so that for a certain data stored in the cloud, only the user bound to the data has a processing right for the data, and the user not bound to the data does not have a processing right for the data, that is, only the user bound to the data can process the data, and the user not bound to the data cannot process the data, so that the security of the user may be improved.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a data processing method based on a video network according to the present invention is shown, which may specifically include the following steps:

After the video network server receives the data processing request, step S102 is executed.

When a certain data is stored in the cloud, the data to be stored can be stored in a storage space in the cloud, and the data identifier of the data and the space identifier of the storage space form a corresponding table entry and are stored in the corresponding relationship between the preset data identifier of the data and the space identifier of the storage space.
In this way, in this step, the space identifier corresponding to the data identifier may be determined according to the correspondence between the preset data identifier of the data and the space identifier of the storage space; and determining the storage space corresponding to the space identifier as a target storage space in which the data corresponding to the data identifier is stored.
In step S103, determining whether the user corresponding to the user identifier has a processing right for the data stored in the target storage space;
if the user corresponding to the user identifier has processing authority for the data stored in the target storage space, in step S104, the data corresponding to the data identifier stored in the target storage space is processed according to the data processing request.
Further, if the user corresponding to the user identifier has a processing right on the data stored in the target storage space, in order to enable the user to more conveniently process the data stored in the target storage space, in another embodiment of the present invention, the data identifier of the data stored in the target storage space may also be obtained; and generating a first notification message according to the acquired data identifier, wherein the first notification message is used for notifying a user corresponding to the user identifier that the data corresponding to the acquired data identifier has processing authority, and then sending the first notification message to the video network terminal. After receiving the first notification message, the video networking terminal can display the data identifier of the data stored in the target storage space carried by the first notification message, so that a user can know which data stored in the cloud end have the processing permission, and the video networking terminal can directly resend the data processing request for processing other data without manually checking which data stored in the cloud end have the processing permission, so that the video networking server can process other data according to other processing requests.
In the embodiment of the invention, a data processing request sent by a video network terminal is received, wherein the data processing request at least comprises a user identifier and a data identifier of a user, and the data processing request is used for requesting to process data which is stored in a cloud and corresponds to the data identifier; determining a target storage space in which data corresponding to the data identification is stored in a plurality of different storage spaces included in the cloud; judging whether the user corresponding to the user identification has processing authority on the data stored in the target storage space; and if the user corresponding to the user identification has processing authority to the data stored in the target storage space, processing the data corresponding to the data identification stored in the target storage space according to the data processing request.
According to the embodiment of the invention, the data stored in the cloud end can be bound with the users, so that for a certain data stored in the cloud end, only the user bound with the data has the processing authority to the data, and the user not bound with the data does not have the processing authority to the data, that is, only the user bound with the data can process the data, and the user not bound with the data cannot process the data, so that the safety of the user can be improved.
Wherein, referring to fig. 6, step S103 includes:
in step S201, according to a preset correspondence between a user identifier of a user and a space identifier of a storage space, determining a space identifier corresponding to the user identifier;
in the embodiment of the present invention, for any one storage space in the cloud, the user identifiers of users having processing permissions on data stored in the storage space may be counted in advance, then each counted user identifier forms a corresponding table entry with the space identifier of the storage space, and is stored in the preset corresponding relationship between the user identifier of the user and the space identifier of the storage space, and the above operations are performed for each other storage space in the cloud.
In step S202, it is determined whether the determined space identifier includes a space identifier of the target storage space;
if the determined space identifier includes the space identifier of the target storage space, in step S203, it is determined that the user corresponding to the user identifier has a processing right on the data stored in the target storage space.
In order to enable the user to process the data stored in the cloud more conveniently, in another embodiment of the present invention, a second notification message may be generated according to the determined space identifier, where the second notification message is used to notify the user corresponding to the user identifier that the data stored in the storage space corresponding to the determined space identifier has the processing permission, and then the second notification message is sent to the video networking terminal. After receiving the second notification message, the video network terminal can display the space identifier carried by the second notification message, so that the user can know that the user has processing authority for the data stored in the storage space. Therefore, the data processing request for processing other data can be directly sent again without manually checking which storage spaces have processing authority to the data stored in the storage spaces, so that the video network server processes other data according to other processing requests.
And if the determined space identification does not comprise the space identification of the target storage space, determining that the user corresponding to the user identification does not have the processing authority on the data stored in the target storage space. Further, a third notification message may be generated according to the data identifier, where the third notification message is used to notify that the user corresponding to the user identifier does not have a processing right on the data corresponding to the data identifier, and then the third notification message is sent to the video networking terminal, and after receiving the third notification message, the video networking terminal may display the data identifier of the data stored in the target storage space carried by the third notification message, so that the user may know that the user does not have a processing right on the data corresponding to the data identifier.
However, in the foregoing embodiment, if a lawless person steals the user identifier of the user, the data corresponding to the data identifier stored in the cloud may be processed, and further, a loss may be caused to the user, so in order to further improve the security of the data stored in the cloud, in yet another embodiment of the present invention, in addition to binding the user identifier and the target space identifier, the video network terminal used by the user may be bound to the target storage space, for example, a corresponding table entry may be formed by the space identifier of the target storage space and the terminal identifier of the video network terminal used by the user, and stored in the corresponding relationship between the preset space identifier of the storage space and the terminal identifier of the terminal.
Thus, the data processing request also needs to carry the terminal identifier of the video network terminal.
Therefore, when determining whether the user corresponding to the user identifier has processing right for the data stored in the target storage space, if the determined space identifier includes the space identifier of the target storage space, the terminal identifier corresponding to the space identifier of the target storage space is further determined according to the preset correspondence between the space identifier of the storage space and the terminal identifier of the terminal; judging whether the determined terminal identification comprises the terminal identification carried by the data processing request; and if the determined terminal identification comprises the terminal identification carried by the data processing request, determining that the user corresponding to the user identification has the processing authority for the data stored in the target storage space.
Therefore, even if a lawbreaker steals the user identification of the user, if the lawbreaker does not steal the terminal used by the user, the lawbreaker cannot process the data corresponding to the data identification stored in the cloud.
However, in the foregoing embodiment, if the user identifier of the user is stolen by a lawless person, the data corresponding to the data identifier stored in the cloud may be processed, and further a loss may be caused to the user, so in order to further improve the security of the data stored in the cloud, in yet another embodiment of the present invention, in addition to binding the user identifier with the target space identifier, a location area of the user may be set when the data stored in the target storage space has a processing right, that is, when the user is located in the location area, the user only has a processing right to the data stored in the target storage space, when the user is not located in the location area, the user does not have a processing right to the data stored in the target storage space, and further the location area may be bound with the target storage space, for example, the space identifier of the target storage space and the location area constitute a corresponding table entry, and storing the data in the corresponding relation between the space identifier and the position area of the preset storage space. For example, the location area is an area where the user's home is located, or is an area where the user's office is located, or the like, which is not a public area.
Thus, the data processing request also needs to carry the current location information of the user. The current position information of the user can be the current position information of the video network terminal used by the user, and the like.
Therefore, when determining whether the user corresponding to the user identifier has processing right for the data stored in the target storage space, if the determined space identifier includes the space identifier of the target storage space, the location area corresponding to the space identifier of the target storage space is determined according to the preset correspondence between the space identifier of the storage space and the location area; judging whether the current position area of the user is located in the position area; and if the current position area of the user is positioned in the position area, determining that the user corresponding to the user identification has processing authority on the data stored in the target storage space.
For example, the location area is a non-public area that a lawbreaker typically cannot enter, e.g., cannot enter the user's home or the user's office. Even if a lawbreaker steals the user identification of the user, the lawbreaker cannot go to the location area generally, and if the lawbreaker is not located in the location area, the data corresponding to the data identification stored in the cloud cannot be processed.
For example, assuming that the data corresponding to the data identifier stored in the target storage space is confidential data of a certain company, and the user identifier is a user identifier of a certain employee of the company, in order to avoid that a lawless person can steal the data corresponding to the data identifier stored in the cloud after stealing the user identifier, a location area when the data corresponding to the data identifier stored in the target storage space has a processing right can be set, for example, the location area is set as an area where the company is located, that is, when the user is located in the location area, the user can only have a processing right on the data stored in the target storage space. Lawbreakers often cannot enter the area where the company is located, and therefore, the data corresponding to the data identifier stored in the cloud cannot be processed only through the stolen user identifier. Even if a lawbreaker accidentally enters the area where the company is located, the lawbreaker can be found and driven out of the area where the company is located by the personnel of the company, and further the data corresponding to the data identification stored in the cloud cannot be processed through the stolen user identification, so that the safety of the data stored in the cloud is improved.
In the embodiment of the present invention, the processing manner for processing the data stored in the cloud includes multiple manners, for example, accessing the data stored in the cloud, deleting the data stored in the cloud, updating the data stored in the cloud, and the like. When a user has a processing right for data stored in a certain storage space, in order to further improve the security of the data, the processing mode of the user for the data stored in the storage space may be further limited.
For example, for a low-level user, the processing manner of the user on the data stored in the storage space may be set as follows: data stored in the storage space is accessed without deleting the data stored in the storage space or without updating the data stored in the storage space.
For another example, for a user at a high level, the processing manner of the user on the data stored in the storage space may be set as follows: accessing data stored in the storage space, deleting data stored in the storage space, and updating data stored in the storage space.
Therefore, in the embodiment of the present invention, the data processing request further carries a processing mode, and the data processing request is used for requesting to process the data corresponding to the data identifier, which is stored in the cloud, according to the processing mode;
therefore, step S103 may be: and judging whether the user corresponding to the user identification has the processing authority for processing the data stored in the target storage space according to the processing mode.
For any storage space in the cloud, when a user has a processing right for processing data stored in the storage space according to a certain processing mode, a corresponding table entry can be formed by the user identifier of the user, the space identifier of the storage space and the processing mode and stored in a corresponding relation among the preset user identifier, the space identifier of the storage space and the processing mode, so that when the user corresponding to the user identifier judges whether the processing right for processing the data stored in the target storage space according to the processing mode exists, whether the space identifier of the storage space and the corresponding table entry of the processing mode exist or not can be searched in the corresponding relation among the preset user identifier, the space identifier of the storage space and the processing mode, and if the space identifier of the storage space, the space identifier of the target storage space and the corresponding table entry of the processing mode exist, the corresponding table entry of the processing mode includes the user identifier, And if the space identifier of the target storage space and the corresponding table entry of the processing mode do not exist, the user corresponding to the user identifier does not have the processing authority for processing the data stored in the target storage space according to the processing mode.
