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 flowchart of the steps of a method for video networking based configuration distribution is shown, according to one embodiment of the present invention.
In the video network, a plurality of local video networks are distributed, namely, the local video networks are computer communication networks which are formed by connecting various video network terminals, video network servers, peripheral equipment and the like in a local geographic range (such as Beijing area, Xinjiang area and the like) and apply video network protocols.
Each local area video network is provided with a video network storage server, and a certain local area video network is provided with a video network management server.

In addition, the bridge server simultaneously accesses the local area video network where the video network storage server is located and the local area video network where the video network management server is located.
By access, it may be meant a network access operation according to the V2V protocol, obtaining the legal identity of the local area network, so that the bridge server can communicate in both local area networks simultaneously.
For the video network management server, video network load information of the video network storage server in the video network, such as occupation information of bandwidth, the number of connected video network terminals, and the like, can be detected.
If the load information of the video network reaches the preset load condition, the load is high, and in order to reduce the load of the video network, first access information of a video network storage server in an IP network, such as an IP address, a port number and the like, can be inquired.
And distributing the video network storage configuration information to the video network storage server in the IP network according to the first access information.
If the load information of the video network does not reach the preset load condition, the load is low, and in order to ensure the safety of the storage configuration information of the video network, the storage configuration information of the video network can be distributed to a storage server of the video network through a bridge server in the video network.
Further, the bridge server generates a first virtual terminal in the local area video network where the video network storage server is located, and generates a second virtual terminal in the local area video network where the video network management server is located.
In the local area video network where the video network storage server is located, the bridge server uses the first virtual terminal to communicate with the video network storage server, in the local area video network where the video network management server is located, the bridge server uses the second virtual terminal to communicate with the video network management server, and inside the bridge server, data is transmitted between the first virtual terminal and the second virtual terminal, so that the video network storage server and the video network management server can communicate across the local area video network.
After the storage server receives the configuration information, the service of the video network applying the configuration information can be inquired to be updated.
In one example, the video networking storage configuration information includes at least one of:
transcoding configuration information, video networking number, communication strategy (such as speed priority, stability priority and the like) with a video networking service platform and a video networking terminal.
In this example, if the storage configuration information of the video network is transcoding configuration information, it is determined that the video network service corresponding to the storage configuration information of the video network is a media processing service, and the media processing service may apply the transcoding configuration information to perform encoding and decoding processing on video data and audio data.
And if the video networking storage configuration information is a video networking number, determining that the video networking service corresponding to the video networking storage configuration information is an on-demand service, a storage gateway and a conference service, wherein the on-demand service, the storage gateway and the conference service can generate a virtual video networking terminal by using the video networking number.
And if the storage configuration information of the video network is a communication strategy, determining that the video network service corresponding to the storage configuration information of the video network is a storage gateway, and the storage gateway can communicate with a video network service platform and a video network terminal in the video network and the IP network by applying the communication strategy.

In addition, besides the above-mentioned storage configuration information of the video network and the video network service corresponding to the storage configuration information, a person skilled in the art may also adopt other storage configuration information of the video network and the video network service corresponding to the storage configuration information of the video network according to actual needs, which is not limited in this embodiment of the present invention.
The configuration of the video networking service distributed by the video networking management server can be configured in a hot update mode.
In a specific implementation, a first storage area of the video networking service for storing the configuration information in the cache and a second storage area of the video networking service for storing the configuration information in the database can be searched.
And updating the storage configuration information of the video network to a first storage area in the cache so as to replace the old storage configuration information of the video network in the cache.
And updating the storage configuration information of the video network to a second storage area in the database so as to replace the old storage configuration information of the video network in the database.
In the embodiment of the invention, the video networking management server determines the video networking storage configuration information to be distributed, distributes the video networking storage configuration information to the video networking storage server, the video networking storage server inquires the video networking service corresponding to the video networking storage configuration information, the video networking service configures the video networking storage configuration information, the networking management service can be configured in a centralized manner, a user does not need to log in a system one by one or remotely configure the video networking management server, the repeated labor is reduced, the configuration efficiency is improved, and the error probability is reduced.

and a substep S11, acquiring a first content identifier generated by the internet of view management server for the internet of view storage configuration information.
And a substep S12 of generating a second content identification for the video network storage configuration information.
A substep S13, determining whether the first content identifier is the same as the second content identifier; if yes, go to substep S14, otherwise go to substep S15.
Substep S14, determining that the storage configuration of the video network passes the legitimacy check.
Substep S15, determining that the view network storage configuration fails the legitimacy check.
In the embodiment of the invention, the generation modes of the content identification, such as a key, character shift, an encryption algorithm and the like, are negotiated in advance between the video network management server and the video network storage server.
And the video network management server generates a first content identifier according to the video network storage configuration information in the generation mode, and sends the first content identifier and the video network storage configuration information to the video network storage server.
After receiving the storage configuration information of the video network and the first content identification, the storage server of the video network generates a second content identification according to the storage configuration information of the video network in the same generation mode, and compares the first content identification with the second content identification.
If the two are the same, determining that the storage configuration of the video network passes the validity check and is not tampered, otherwise, determining that the storage configuration of the video network does not pass the validity check and is tampered.
Of course, if the storage configuration information of the video network is transmitted between the video network management server and the video network storage server through the video network, the validity of the storage configuration information of the video network may also be checked, which is not limited in the embodiment of the present invention.
And if the storage configuration of the video network passes the validity check, the video network service corresponding to the storage configuration information of the video network can be inquired, and if not, the storage configuration of the video network is discarded.
In one case, the storage server generates a configuration result with successful configuration after the application of the configuration information by the storage server.
In another case, the storage server generates a configuration result with failed configuration after the application of the configuration information by the storage server fails.
In the embodiment of the invention, after the configuration result is generated, the configuration result is fed back to the video network management server by the video network storage server.
In addition, for different network conditions, communication links between different video network storage servers and video network management servers can be established, so that video network load information of the video network storage servers can be detected, the communication link distributed at this time can be determined, and the configuration result can be sent to the video network management server through the communication link.

In addition, the bridge server simultaneously accesses the local area video network where the video network storage server is located and the local area video network where the video network management server is located.
For the video network storage server, video network load information of the video network storage server in the video network, such as occupation information of bandwidth, the number of connected video network terminals, and the like, can be detected.
And if the load information of the video network reaches the preset load condition, the load is higher, and in order to reduce the load of the video network, second access information of the video network management server in the IP network, such as an IP address, a port number and the like, is inquired.

Further, the management server of the video network may send the configuration result of the failed configuration to an account of the administrator, and display the configuration result to the administrator.
When the administrator sends a retransmission instruction to the configuration result of the configuration failure through the account, the storage configuration information of the video network is written into the sending queue to be used as the storage configuration information of the video network to be distributed, and the distribution is carried out again, so that the successful application of the storage configuration information of the video network is ensured.
