Moreover, a plurality of video networking terminals included in the system inevitably have video networking terminals which cannot modify the information content of the video networking information, and it takes much time to modify the information content of the video networking information, while it only can take less time to add a timestamp to the video networking information without modifying the information content of the video networking information.
If a certain video network terminal modifies the information content of the first video network information after receiving the first video network information to obtain third video network information, if the third video network information is broadcasted in the whole network, the initial broadcasting time of the third video network information is necessarily later than the initial broadcasting time of the first video network information, namely, the receiving time of other video network terminals receiving the third video network information is necessarily later than the first time of receiving the first video network information.
Therefore, the situation that the moment when the total checked times of the second video networking information reach the preset times is later than the moment when the total checked times of the third video networking information reach the preset times is avoided, the whole system can reach the consistency of the second video networking information earlier in the whole system by selecting the earliest time criterion, and can not reach the consistency of the third video networking information earlier, so that the condition that the video networking server receives the uploaded video networking information which is the first video networking information instead of other video networking information obtained after the information content of the first video networking information is tampered is ensured.

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.
Referring to fig. 5, a block diagram of a system for checking video networking information according to the present application is shown, the system including: a video network server 01 and a plurality of video network terminals 02; each video network terminal 02 is in communication connection with a video network server 01. In addition, after any one of the video networking terminals broadcasts the video networking information, other video networking terminals and the video networking server can receive the broadcasted video networking information.
In the application, based on some requirements, the video network terminal may need to upload the first video network information to the video network server, so that the video network server stores the first video network information. The video network terminal can directly send first video network information to the video network server, and the video network server receives the first video network information and then stores the first video network information.
However, in the process of transmitting the first video networking information from the video networking terminal to the video networking server, the first video networking information may be intercepted by a lawbreaker, and then the first video networking information is modified, and then the original first video networking information is not sent to the video networking server, but the modified first video networking information is sent to the video networking server, so that the first video networking information received by the video networking server is different from the video networking information uploaded by the video networking terminal, and the purpose of the video networking terminal cannot be achieved.
Therefore, in the application, it needs to be ensured that the first video network information stored by the video network server is the same as the video network information uploaded by the video network terminal.
When the terminal of the video network uploads the first video network information to the video network server so that the video network server stores the first video network server, the terminal of the video network can broadcast the first video network information in the system shown in fig. 1.
Then, each of the other video network terminals receives the broadcasted first video network information and stores the first video network information, and then each of the video network terminals that receive the broadcasted first video network information updates the receiving time when the first video network information is received in the first video network information to obtain the second video network information, and then broadcasts the obtained second video network information in the system shown in fig. 1.
Then, for any one of the other terminals, it can ensure that the video network server receives the uploaded video network information as the first video network information, rather than other video network information obtained after tampering the information content of the first video network information, according to the method shown in fig. 6.
Specifically, referring to fig. 6, a flowchart illustrating steps of a method for processing video network information according to the present application is shown, where the method may be applied to any one of the video network terminals 02 in the system shown in fig. 5, and the method may specifically include the following steps:
in step S101, receiving broadcasted second video network information generated via at least the first video network information;
in this application, the second video networking information is generated via the first video networking information. For example, assume that the previous video network terminal 1 broadcasts the first video network information in the system shown in fig. 5. The video network terminal 2 receives the broadcasted first video network information, then updates the first video network information according to the receiving time of the received first video network information to obtain second video network information, then broadcasts the second video network information in the system shown in fig. 5, and the video network terminal 3 receives the broadcasted second video network information. As can be seen, the second video networking information received by the video networking terminal 3 is obtained by updating the first video networking information broadcast by the video networking terminal 1 by the video networking terminal 2.
In one embodiment of the application, the second video networking information can be obtained after the first video networking information is updated, and other video networking information is not separated between the first video networking information and the second video networking information in the updating stage.
Or, in another embodiment of the present application, one piece of second networking information obtained by updating the first networking information is updated to obtain another piece of second networking information, or the one piece of second networking information is updated to obtain another piece of second networking information, and the another piece of second networking information is updated to obtain another piece of second networking information, that is, another piece of second networking information. At the updating stage, at least one piece of video network information is not separated between the first video network information and the received second video network information.
In step S102, first video network information of a broadcast that has been received before the second video network information is received is acquired; the information identification of the first video networking information is the same as the information identification of the second video networking information;
in the application, one piece of video networking information is updated to obtain the other piece of video networking information, and then the two pieces of video networking information belong to the same family of video networking information.
The video networking information in the application at least comprises information identification, information content and the like, and the information identification in the video networking information belonging to the same family is the same.
Before the broadcasted second video networking information is received, the broadcasted first video networking information is received and stored locally, so that the information identification of the second video networking information can be obtained; the information identifier can be located in a preset field in the second video network information, and then the receiving time when the second video network information is received is obtained; and then searching the video networking information which corresponds to the information identification and comprises a timestamp earlier than the receiving time in the video networking information of the broadcast received in advance, and using the video networking information as the first video networking information.
In the application, after receiving one piece of video networking information, the receiving time of the video networking information can be acquired, and the receiving time is used as a time stamp to be added into the video networking information.
In the application, after the broadcasted second video network information is received, the receiving time when the second video network information is received can be acquired, and the receiving time is added to the second video network information as a timestamp.
In step S103, checking whether the information content of the first video network information is the same as the information content of the second video network information;
in an embodiment of the present application, the first video networking information may be encrypted video networking information, for example, the first video networking information is obtained by encrypting original video networking information using a private key of a video networking terminal that broadcasts the first video networking information, and in the present application, the public key corresponding to the private key may be used to decrypt the first video networking information to obtain the original video networking information, and then obtain information content in the original video networking information. Similarly, the information content of the second video network information can also be acquired in the above manner; the information content of the first video network information and the information content of the second video network information can be checked whether the information content of the first video network information is the same or not.
For example, the information content of the first internet-of-view information may be hashed to obtain a first hash value, the information content of the second internet-of-view information may be hashed to obtain a second hash value, whether the first hash value is the same as the second hash value is compared, if the first hash value is the same as the second hash value, it may be determined that the information content of the first internet-of-view information is the same as the information content of the second internet-of-view information, and if the first hash value is different from the second hash value, it may be determined that the information content of the first internet-of-view information is different from the information content of the second internet-of-view information.
Under the condition that the information content of the first video network information is the same as that of the second video network information, in step S104, counting the total times of checking the second video network information;
in the application, each time the information content of the second video network information obtained by directly or indirectly updating the first video network information and the information content of the first video network information are verified, the total number of times of verification of the second video network information is increased in the second video network information.
Thus, in this step, the recorded total number of times of verification can be obtained in the second network of vision information.
The total number of times that the second video networking information is verified in the present application includes: the total number of checks involved in updating from the first to the second video networking information.
For example, assume that the second video network information 5 received at this time, the second video network information 5 is obtained by checking the first video network information and the second video network information 4 by a video network terminal, the second video network information 4 is obtained by updating the second video network information 4, the first video network information and the second video network information 3 are checked by a video network terminal, the second video network information 3 is obtained by updating the second video network information 3, the second video network information 2 is obtained by updating the second video network information 2 after checking the first video network information and the second video network information 2by a video network terminal, and the second video network information 1 is obtained by updating the second video network information 1 after checking the first video network information and the second video network information 1 by a video network terminal.
Thus, the total number of times the second video network information 5 is verified is 4.
In step S105, in a case that the total number of times reaches the preset number of times, sending first prompt information to the video network server, where the first prompt information is used to indicate that the total number of times that the second video network information is verified reaches the preset number of times.
The preset times comprise 6, 8 or 10 and the like, in the application, under the condition that the total times reaches the preset times, the fact that a plurality of pieces of video networking equipment verify the second video networking information is described, and the information content of the two pieces of video networking information is the same in each verification process, so that the fact that the first video networking information is effective can be described, the video networking information which is originally uploaded to the video networking server by the video networking equipment broadcasting the first video networking information is required, therefore, the first prompt information can be sent to the video networking server, and the first prompt information is used for indicating that the total times of the second video networking information which is verified reaches the preset times.
After the video networking server receives the first prompt message, the video networking server can know that the total times of the second video networking message being checked reaches the preset times, and then can determine that the first video networking message is effective, so that the first video networking message can be stored in the video networking server, and therefore the video networking message which is uploaded to the video networking server by the video networking terminal is the same as the video networking message which is actually received and stored by the video networking server.
In another embodiment of the present application, under the condition that the information content of the first video networking information is different from the information content of the second video networking information, it indicates that the second video networking information is obtained after tampering the information content of the first video networking information, and is not the video networking information that the video networking terminal originally needs to upload to the video networking server, so that the second prompt information is not continuously broadcast any more, and the second prompt information can be broadcast, where the second prompt information is used to prompt that the information content of the first video networking information is different from the information content of the second video networking information. Therefore, the technical staff can be prompted, so that the technical staff can focus on the second video network information and the video network terminal broadcasting the second video network information, and whether the video network terminal is penetrated by lawbreakers or not is mainly checked, and potential safety hazards are eliminated in time.
Further, the second video network information can be deleted for the storage space of the video network terminal.
Under the condition that the information content of the first video networking information is the same as that of the second video networking information and the total frequency does not reach the preset frequency, it is indicated that the second video networking information is not obtained after the information content of the first video networking information is tampered, but because the total frequency does not reach the preset frequency, the second video networking information needs to be continuously broadcast to enable other video networking terminals in the system shown in fig. 5 to continuously verify the second video networking information, wherein the total frequency of verified second video networking information can be updated in the second video networking information, and then the updated second video networking information is broadcast.
Through the application, when the video network terminal needs to upload the first video network information to the video network server, the first video network information can be broadcasted to a plurality of video network terminals in the system, the first video network information broadcasted can be received by the plurality of video network terminals respectively, each video network terminal receiving the first video network information broadcasted can store the first video network information respectively, then the first video network information is updated, the receiving time when the first video network information is received is added to the first video network information, the second video network information is obtained, and then the second video network information obtained by each other is broadcasted in the system respectively. Then, for any one of the other terminals, it can be ensured that the video networking server receives the uploaded video networking information as the first video networking information according to the method of the present application, instead of the other video networking information obtained after tampering the information content of the first video networking information.
For example, under the mechanism of the present application, after a certain video network terminal in the system receives broadcasted first video network information, if the information content in the first video network information is modified to obtain second video network information, and then the second video network information is broadcasted, each other video network terminal in the system receives the second video network information, and then it is verified whether the information content of the first video network information is the same as the information content of the second video network information, and at this time it is determined that the information content is different from the second video network information, the second video network information is not processed any more, and the second video network information is not broadcasted in the system any more, so the number of times of verifying the second video network information does not increase any more, and then the preset number of times is not reached, and therefore, the first prompt information is not sent to the video network server.
Moreover, a plurality of video networking terminals included in the system inevitably have video networking terminals which cannot modify the information content of the video networking information, and it takes much time to modify the information content of the video networking information, while it only can take less time to add a timestamp to the video networking information without modifying the information content of the video networking information.
If a certain video network terminal modifies the information content of the first video network information after receiving the first video network information to obtain third video network information, if the third video network information is broadcasted in the whole network, the initial broadcasting time of the third video network information is necessarily later than the initial broadcasting time of the first video network information, namely, the receiving time of other video network terminals receiving the third video network information is necessarily later than the first time of receiving the first video network information.
Therefore, the situation that the moment when the total checked times of the second video networking information reach the preset times is later than the moment when the total checked times of the third video networking information reach the preset times is avoided, the whole system can reach the consistency of the second video networking information earlier in the whole system by selecting the earliest time criterion, and can not reach the consistency of the third video networking information earlier, so that the condition that the video networking server receives the uploaded video networking information which is the first video networking information instead of other video networking information obtained after the information content of the first video networking information is tampered is ensured.
