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, the video network resource release method applied to the video network is provided in the embodiment of the invention.
Example one
Referring to fig. 5, a flowchart illustrating steps of a method for releasing resources of a video network according to a first embodiment of the present invention is shown, where the method may be applied to a video network, and specifically may include the following steps:
step 501: and the video networking sharing platform server receives a monitoring viewing request sent by a third-party platform.
And the third-party platform sends a monitoring viewing request to the video networking sharing platform server through the Internet so as to view a monitoring video in a certain specific scene. The monitoring viewing request can carry identification information of a third-party platform, identification information of a monitoring resource end of a monitoring video and the like.
And the third-party platform sends a monitoring and viewing request through an internet data channel established between the third-party platform and the monitoring and co-transformation server.
Step 502: and transmitting the monitoring checking request to a monitoring coordination and conversion server after carrying out transmission protocol conversion.
The video networking sharing platform server and the monitoring protocol conversion server are in data transmission through a video networking protocol, and the monitoring protocol conversion server can be accessed to a monitoring resource end through an internet protocol. And the monitoring protocol conversion server monitors the video code stream from the monitoring resource end and sends the monitoring video code stream to the third-party platform so as to allow the video networking user to check the monitoring video through the third-party platform.
Step 503: and receiving a monitoring video code stream sent by the monitoring co-transfer server.
After receiving a monitoring viewing request sent by a video network platform server, a monitoring protocol conversion server determines a target monitoring resource end required to be requested to view by the monitoring viewing request, acquires a monitoring video code stream from the target monitoring resource end and then sends the monitoring video code stream to a video network sharing platform server through a video network.
Step 504: and actively establishing TCP connection with the third-party platform.
The video networking sharing platform server starts a TCP (Transmission Control Protocol) service, provides an IP port for the service, and actively establishes TCP connection with a third-party platform through the IP port.
Step 505: and sending the monitoring video code stream to a third-party platform through TCP connection.
And successfully establishing TCP connection between the video networking sharing platform server and the third-party platform, and sending the monitoring video code stream to the third-party platform based on the established TCP connection. In the specific implementation process, the monitoring resource terminal collects video pictures in a monitoring area in real time, converts the collected video pictures into monitoring video code streams and sends the monitoring video code streams to the monitoring transfer server after receiving a monitoring video acquisition request sent by the monitoring transfer server, and the monitoring transfer server sends the monitoring video code streams to the video network sharing platform server through the video network.

Example two
Referring to fig. 6, a flowchart illustrating steps of a method for releasing resources of a video network according to a second embodiment of the present invention is shown, where the method may be applied to a video network, and specifically may include the following steps:
step 601: and the video networking sharing platform server receives a monitoring viewing request sent by a third-party platform.
And the third-party platform sends a monitoring and viewing request through an internet data channel established between the third-party platform and the monitoring and co-transformation server. Namely, the third party platform sends a monitoring and viewing request to the video networking sharing platform server through the IP protocol.
Step 602: and converting the monitoring viewing request from the Internet protocol request into a video Internet protocol request, and then sending the video Internet protocol request to the monitoring coordination and conversion server.
The video network sharing platform server and the monitoring protocol conversion server are communicated through the video network, so that the monitoring viewing request needs to be converted from an internet protocol request into a video network protocol and then sent to the monitoring protocol conversion server.
Step 603: and receiving a monitoring video code stream sent by the monitoring co-transfer server.
And after receiving the monitoring viewing request sent by the video networking sharing platform server, the monitoring protocol conversion server responds to the request to acquire a monitoring video code stream and then sends the monitoring video code stream to the video networking sharing platform server.
A mode for optionally sending a monitoring video code stream to a video networking sharing platform server by a monitoring co-transformation server is as follows:
the monitoring coordination server judges whether the monitoring check request is effective or not; if the video data is valid, converting the video data requested to be checked by the monitoring check request into a monitoring video code stream through a video network data channel between the video network sharing platform server and the video network sharing platform server, and sending the monitoring video code stream to the video network sharing platform server.
When determining whether the monitoring viewing request is valid, the identification information of the third-party platform can be extracted from the monitoring video viewing request, and whether the extracted identification information of the third-party platform is in a platform identification list which can apply for the monitoring video is judged, if yes, the monitoring viewing request is determined to be valid, otherwise, the monitoring viewing request is determined to be invalid.
In the optional mode, the monitoring video code stream is sent to the video networking sharing platform server after the monitoring viewing request is determined to be valid, so that the monitoring video can be prevented from being maliciously stolen by some third-party platforms.
Step 604: and actively establishing TCP connection with the third-party platform.
One way to optionally actively establish a TCP connection with a third party platform for a shared platform server over the internet of view is as follows: the video network sharing platform server starts TCP service; actively linking to a third-party platform through a TCP service, and establishing a TCP connection with a third-party sharing platform.
Step 605: and sending the monitoring video code stream to a third-party platform through TCP connection.
And successfully establishing TCP connection between the video networking sharing platform server and the third-party platform, and sending the monitoring video code stream to the third-party platform based on the established TCP connection. In the specific implementation process, the monitoring resource terminal collects video pictures in a monitoring area in real time, converts the collected video pictures into monitoring video code streams and sends the monitoring video code streams to the monitoring transfer server after receiving a monitoring video acquisition request sent by the monitoring transfer server, and the monitoring transfer server sends the monitoring video code streams to the video network sharing platform server through the video network.
Step 606: and monitoring whether the TCP connection is interrupted or not in the process of sending the monitoring video code stream to the third-party platform through the TCP connection.
And after the third-party platform successfully receives the monitoring video code stream sent by the video networking sharing platform server, decoding the monitoring video code stream to obtain a video picture, and displaying the video picture on the third-party platform. After the TCP connection between the video networking sharing platform server and the third-party platform is successfully established, the video networking sharing platform server detects whether the TCP connection is interrupted or not in a timing or real-time mode, and therefore whether the third-party platform exits abnormally or whether the network is interrupted or not is determined.
Step 607: and when the TCP connection is interrupted, releasing the channel resources distributed for the TCP connection by the video networking shared platform server.
Specifically, if the TCP connection is not interrupted, it may be determined that the third party platform is not abnormally exited and the network is not interrupted; otherwise, if the TCP connection is interrupted, the third-party platform can be determined to be abnormally quitted or the network is interrupted.
Step 608: and sending a monitoring stop instruction to the monitoring co-rotation server, and releasing resources occupied by a video network data channel between the monitoring co-rotation server and the monitoring co-rotation server.
In the video monitoring process, video networking network resources distributed by the video networking sharing platform server for the third party platform and video networking resources occupied by the video networking data channel distributed by the video networking sharing platform server for the monitoring protocol conversion server are mainly occupied. The method not only releases the channel resources distributed by the video network sharing platform server for TCP connection, but also releases the resources occupied by the video network data channel between the video network sharing platform server and the monitoring co-transformation server.
It should be noted that step 608 is not limited to be executed after step 607, and may be executed in parallel with step 607 or before step 607, which is not specifically limited in the embodiment of the present invention.
