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 present application: 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 networking, one of the core concepts of the application is provided, the video networking number distributed for receiving the video based on the video networking protocol from the video networking protocol transfer server can be released in time according to the protocol of the video networking, so that the video networking number can be used in other occasions, the video networking number is prevented from being wasted, and the utilization rate of the video networking number is improved.

in step S101, in the process of sending the video based on the internet protocol to the internet media server, detecting whether indication information that the number fed back by the internet media server exceeds a preset number is received within a preset time period, where the indication information is used to indicate that a video receiving port of the internet media server is unreachable;
when a user needs to acquire a video stored in the video networking coordination and conversion server, the internet platform can be used for sending a video stream adjusting signaling to the main video networking server, the main video networking server receives the video stream adjusting signaling and sends the video stream adjusting signaling to the video networking media sharing platform, and the video networking media sharing platform receives the video stream adjusting signaling sent by the video networking main server.
Sending the video stream adjusting signaling to a video networking protocol conversion server; the video network coordination and conversion server receives the video stream adjusting signaling and then sends a stream adjusting success response to the video network media sharing platform, and the video network media sharing platform receives the stream adjusting success response returned by the video network coordination and conversion server according to the stream adjusting signaling; and sending a stream-adjusting success response to the video networking main server, receiving the stream-adjusting success response by the video networking main server, sending the stream-adjusting success response to the Internet platform, receiving the stream-adjusting success response by the Internet platform so that a user can acquire a video, sending the stream-adjusting success response to the Internet media server by the Internet platform, and opening a video receiving port by the Internet media server to receive the video.
Secondly, after the video networking protocol conversion server receives a successful response of the stream modulation returned by the video networking protocol conversion server according to the stream modulation signaling, the video networking protocol conversion server can send a video based on a video networking protocol to the video networking media sharing platform, and the video networking media sharing platform can receive the video based on the video networking protocol sent by the video networking protocol conversion server and distributes a video networking number for receiving the video based on the video networking protocol from the video networking protocol conversion server; receiving a video based on a video networking protocol sent by a video networking protocol transfer server according to the video networking number; converting the video based on the video networking protocol into the video based on the Internet protocol; an internet protocol based video is sent to an internet media server.
When receiving a video, the internet media server often needs to open a video receiving port and receive the video through the video receiving port.
In the process of sending the video based on the internet protocol to the internet media server, a user may suddenly no longer need to acquire the video based on the internet protocol, and when the user no longer needs to acquire the video based on the internet protocol, the internet media server may be controlled to close the video receiving port, and then the internet media server no longer receives the video based on the internet protocol.
However, even if the internet media server closes the video receiving port, the video sharing platform of the internet of things can continue to send the video based on the internet protocol to the internet media server, however, because the internet media server closes the video receiving port, when receiving one frame of image in the video, the video sharing platform of the internet of things returns the indication information which is used for indicating that the video receiving port of the internet media server is not reachable; and the video sharing platform of the video network receives the indication information, and further can determine that the video receiving port is closed by the Internet media server.
However, sometimes the internet media server may accidentally shut down the video interface port for some reason and then return to normal: the video receiving port is opened, and in the process of closing the video receiving port, when one frame of image in the video is received, indication information is returned to the video sharing platform of the video network, wherein the indication information is used for indicating that the video receiving port of the internet media server is not accessible; since the internet media server immediately opens the video receiving port, the internet media server cannot be considered to be disconnected.
Therefore, in the present application, if the indication information that the number fed back by the internet media server exceeds the preset number is received within the preset time period, it may be determined that the video receiving port is closed by the internet media server.
The preset time period may be 10 seconds, 11 seconds, 12 seconds, or the like, which is not limited in the embodiment of the present invention.
The predetermined number may be 10 times, 15 times, 20 times, and the like, which is not limited in the embodiment of the present invention.
If the indication information that the number fed back by the internet media server exceeds the preset number is received within the preset time length, in step S102, the video based on the video networking protocol is stopped from being received from the video networking coordination server;
if the indication information that the number fed back by the internet media server exceeds the preset number is received within the preset time length, the internet media server is determined to close the video receiving port, the internet media server which closes the video receiving port does not need to receive the video which is sent by the video networking video sharing platform and is based on the internet protocol, and since the internet media server which closes the video receiving port does not need to receive the video which is sent by the video networking video sharing platform and is based on the internet protocol, in order to save network resources, the video networking video sharing platform does not need to continuously send the video which is based on the internet protocol to the internet media server, and therefore the video networking video sharing platform does not need to continuously receive the video which is based on the video networking protocol from the video networking protocol conversion server; thus, the video sharing platform may stop receiving video based on the video networking protocol from the video networking protocol server.
Specifically, the video networking video sharing platform may send a termination instruction to the video networking protocol conversion server, where the termination instruction is used to instruct the video networking protocol conversion server to stop sending the video based on the video networking protocol to the video networking video sharing platform. After receiving the termination instruction, the video networking protocol conversion server stops sending the video based on the video networking protocol to the video networking video sharing platform.
In step S103, the video network number allocated for receiving the video based on the video network protocol from the video network protocol conversion server is released.
Because no longer receive the video based on the video networking agreement from the video networking protocol transfer server, then can release for receiving the video based on the video networking agreement from the video networking protocol transfer server and the video networking number that distributes to make this video networking number can be used in other occasions, avoid the video networking number to be wasted, improved the utilization ratio of video networking number.
In the embodiment of the invention, in the process of sending the video based on the internet protocol to the internet media server, whether indication information that the number fed back by the internet media server exceeds the preset number is received in the preset time length is detected, and the indication information is used for indicating that a video receiving port of the internet media server is unreachable; if the indication information that the number fed back by the Internet media server exceeds the preset number is received within the preset time length, stopping receiving the video based on the video networking protocol from the video networking protocol conversion server; releasing the video networking number allocated for receiving the video based on the video networking protocol from the video networking protocol conversion server. The embodiment of the invention can determine whether the video receiving port of the internet media server is closed or not through the indication information, if the video receiving port is closed, the video based on the internet protocol sent by the video networking media sharing platform does not need to be received, therefore, the video network media sharing platform does not need to continuously send the video based on the internet protocol to the internet media server and then receive the video based on the internet protocol sent by the video network protocol conversion server, since the video over the video networking protocol is no longer received from the video networking protocol translation server, the video networking number assigned to receive the video over the video networking protocol from the video networking protocol translation server may be released, so that the video networking number can be used in other occasions, the video networking number is prevented from being wasted, and the utilization rate of the video networking number is improved.
