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.

In the embodiment of the present invention, this is not particularly limited.

Step 602: the protocol conversion server acquires a target video from a target video acquisition terminal corresponding to the video acquisition terminal identification and sets an identity identification for the target video; the identity mark comprises: the first virtual terminal number of the protocol conversion server and the video acquisition terminal identification.

In this embodiment of the present invention, after the coordination conversion server 502 receives the stream tuning instruction, the coordination conversion server 502 may obtain a target video from a target video acquisition terminal corresponding to the video acquisition terminal identifier, and set an identity identifier for the target video; the above identity may include: the first virtual terminal number of the protocol conversion server and the video acquisition terminal identification.

Specifically, in order to accurately indicate the source of the target video through the target video, the cooperative conversion server 502 may set, after acquiring the target video, an identity including the first virtual terminal number of the cooperative conversion server and the video capture terminal identifier for the target video. For example, a configuration file of the target video may be obtained, and the first virtual terminal number of the protocol conversion server and the video capture terminal identifier are inserted into a set position of the configuration file, which is not particularly limited in the embodiment of the present invention.

For example, referring to fig. 5, if the protocol conversion server 1 receives a stream modulation instruction sent by the resource protocol conversion server 501, if a video capture terminal identifier included in the stream modulation instruction is: and A, if the video acquisition terminal identifier corresponding to the video acquisition terminal 1 is A. Then, the target video capture terminal that video capture terminal identification a corresponds is video capture terminal 1 promptly, and the server 1 that helps changes obtains the target video from video capture terminal 1, helps changes server 1 and sets up the identification for above-mentioned target video, and this identification can include: the first virtual terminal number 21 of the collaboration server 1 and the identifier a corresponding to the video capture terminal 1.

In an embodiment of the present invention, the collaboration server 502 may collect a terminal or a target video from a target video based on a video networking protocol or an internet protocol. In the embodiment of the present invention, this is not particularly limited.

In this embodiment of the present invention, optionally, the acquiring, by the collaboration server, the target video from the target video capturing terminal corresponding to the video capturing terminal identifier may include: and the protocol conversion server acquires a target video from a target video acquisition terminal corresponding to the video acquisition terminal identification through a video network.

Specifically, the cooperative conversion server 502 may acquire the target video from the target video acquisition terminal 503 corresponding to the video acquisition terminal identifier through the video network, and by virtue of the advantage of the large bandwidth of the video network, the cooperative conversion server 502 may acquire the target video quickly.

Step 603: the protocol conversion server judges whether a video transmission channel exists between the protocol conversion server and the resource pool proxy server;

in the embodiment of the present invention, the video transmission channel may be a channel dedicated to transmitting video between the video networking devices, or the video transmission channel may be a channel dedicated to transmitting video between the video networking devices.

In the embodiment of the present invention, the coordination server 502 may determine whether a video transmission channel exists between the coordination server and the resource pool proxy server 501.

Specifically, the protocol conversion server 502 may store a channel identifier of an existing video transmission channel, where the channel identifier may include a first virtual terminal number of the protocol conversion server and a second virtual terminal number of the resource pool proxy server. The collaboration server 502 may find out, in the stored channel identifier, whether a video transmission channel exists between the collaboration server and the resource pool proxy server 501 according to the second virtual terminal number of the resource pool proxy server 501. In the embodiment of the present invention, this is not particularly limited.

For the above example, referring to fig. 5, the channel identifier of the existing video transmission channel is stored in the collaboration server 1, and the channel identifier may include the first virtual terminal number 21 of the collaboration server and the second virtual terminal number of the resource pool proxy server. The collaboration server 502 may find out, in the stored channel identifier, whether a video transmission channel exists between the collaboration server and the resource pool proxy server 501 according to the second virtual terminal number of the resource pool proxy server 501.

Step 604: and under the condition that a video channel exists, the coordination server sends the target video with the identity mark to the resource pool proxy server through the existing video transmission channel.

In the embodiment of the present invention, in the case that a video channel exists, the collaboration server 502 sends the target video with the identifier to the resource pool proxy server through the existing video transmission channel.

For example, in the above example, if the collaboration server 1 determines that a video transmission channel exists between the collaboration server and the resource pool proxy server 501, the collaboration server 1 sends the target video with the identity identifier to the resource pool proxy server 501 through the existing video transmission channel. The identity may include: the first virtual terminal number 21 of the collaboration server 1 and the identifier a corresponding to the video capture terminal 1. Therefore, virtual terminal numbers do not need to be set for all the video acquisition terminals, the target video can be accurately and quickly judged to be acquired by the video acquisition terminal corresponding to the coordination server through the identity, and the expense on the limited virtual terminal numbers is saved.

In this embodiment of the present invention, optionally, if the existing video transmission channel has a video transmission task, the collaboration server 501 may add the target video into the video transmission queue, manage the video transmission queue in a first-in first-out mode or according to a certain priority, and send the target video to the resource pool proxy server 501. In the embodiment of the present invention, this is not particularly limited.

Step 605: and under the condition that no video channel exists, the cooperative conversion server generates a video transmission channel between the cooperative conversion server and the resource pool proxy server, and sends the target video provided with the identity identifier to the resource pool proxy server through the generated video transmission channel.

In the embodiment of the present invention, in the case that there is no video channel, the coordination server 502 generates a video transmission channel between the coordination server and the resource pool proxy server 501, and sends the target video with the identity identifier to the resource pool proxy server 501 through the generated video transmission channel.

Specifically, in the case that no video channel exists, the coordination server 502 and the resource pool proxy server 501 cannot transmit a video or a video network between them, and then the coordination server 502 may generate a video transmission channel between it and the resource pool proxy server 501, and send the target video with the identification to the resource pool proxy server 501 through the generated video transmission channel.

For example, for the above example, if the collaboration server 1 determines that there is no video transmission channel between the collaboration server 1 and the resource pool proxy server 501, the collaboration server 1 may generate a video transmission channel between the collaboration server 1 and the resource pool proxy server 501, and send the target video with the identity identifier to the resource pool proxy server 501 through the generated video transmission channel. The identity may include: the first virtual terminal number 21 of the collaboration server 1 and the identifier a corresponding to the video capture terminal 1. Therefore, virtual terminal numbers do not need to be set for all the video acquisition terminals, the target video can be accurately and quickly judged to be acquired by the video acquisition terminal corresponding to the coordination server through the identity, and the expense on the limited virtual terminal numbers is saved. In the embodiment of the present invention, the above-mentioned step 604 and step 605 are alternatively executed.

Specifically, the method may include steps 701-711:

step 701: the resource pool proxy server sends a flow adjusting instruction to the protocol conversion server through a video network; the flow adjusting instruction comprises: and identifying the video acquisition terminal.

In this embodiment of the present invention, the step 701 may refer to the step 601, and it should be noted that the resource pool proxy server 501 sends the flow adjustment instruction to the coordination transfer server 502 through the video network, and since the video network has the advantage of large bandwidth, the resource pool proxy server 501 can quickly send the flow adjustment instruction to the coordination transfer server 502.

Step 702: and the cooperative conversion server acquires a target video from a target video acquisition terminal corresponding to the video acquisition terminal identification.

In the embodiment of the present invention, the step 702 may refer to the related description of the step 602, and is not described herein again to avoid repetition.

Step 703: and the cooperative conversion server inserts a first virtual terminal number of the cooperative conversion server into a first preset position of the target video.

In this embodiment of the present invention, the cooperative server 502 may insert a first virtual terminal number of the cooperative server into a first preset position of the target video.

Specifically, the coordination server 502 may insert the first virtual terminal number of the coordination server 502 at a first preset position at the head or a first preset position at the tail of the target video. Alternatively, the cooperative server 502 may obtain the configuration file of the target video, and insert the first virtual terminal number of the cooperative server 502 into the first preset position at the head or the first preset position at the tail of the configuration file, which is not specifically limited in the embodiment of the present invention.

For example, for the above example, the collaboration server 1 may set the first 8 bits of the profile header of the target video as the identification bits, may determine the first 4 bits of the profile header as the first preset position, and inserts the first virtual terminal number 21 of the collaboration server 1 in the first 4 bits of the profile header.

Step 704: and the coordination server is inserted into the video acquisition terminal identification at a second preset position of the target video.

In an embodiment of the present invention, the coordination server 502 may insert the video capture terminal identifier into a second preset position of the target video.

Specifically, the collaboration server 502 may insert the identifier of the video capture terminal 503 into a second preset position at the head or a second preset position at the tail of the target video. Alternatively, the collaboration server 502 may obtain a configuration file of the target video, and insert the identifier of the video capture terminal 503 into a first preset position at the head or a first preset position at the tail of the configuration file, which is not specifically limited in this embodiment of the present invention.

For example, for the above example, the collaboration server 1 may set the first 8 bits of the profile header of the target video as the identification bits, may determine the 5 th to 8 th bits of the profile header as the second preset positions, and insert the identification a of the video capture terminal 1 in the 5 th to 8 th bits of the profile header.

In the embodiment of the invention, the first virtual terminal number of the transfer server is inserted into the first preset position of the target video, and the video acquisition terminal identification is inserted into the second preset position of the target video, so that the first virtual terminal number of the transfer server and the video acquisition terminal identification can be quickly and accurately obtained from the first preset position and the second preset position of the target video through analysis.

Step 705: the protocol conversion server stores a channel identifier of a video transmission channel; the channel identifier includes: the first virtual terminal number of the protocol conversion server and the second virtual terminal number of the resource pool proxy server.

In this embodiment of the present invention, if there is a video transmission channel, the protocol conversion server 502 may store a channel identifier of the video transmission channel, where the channel identifier may include: the first virtual terminal number of the protocol conversion server and the second virtual terminal number of the resource pool proxy server.

In this embodiment of the present invention, the second virtual terminal number of the resource pool proxy server 501 is used to identify the resource pool proxy server 501, and the second virtual terminal number of the resource pool proxy server 501 may be a MAC address of the resource pool proxy server 501, which is not specifically limited in this embodiment of the present invention.

Step 706: and the protocol conversion server acquires a second virtual terminal number of the resource pool proxy server.

In this embodiment of the present invention, the coordination server 502 may obtain the second virtual terminal number of the resource pool proxy server 501.

Specifically, the resource pool proxy server 501 may send the second virtual terminal number to the coordination server 501, and the like. In the embodiment of the present invention, this is not particularly limited.

Step 707: and the protocol conversion server searches whether a channel identifier matched with the second virtual terminal number exists in the stored channel identifiers.

In this embodiment of the present invention, the protocol conversion server 502 may search whether a channel identifier matching the second virtual terminal number exists in the stored channel identifiers.

For example, for the above example, if the second virtual terminal number corresponding to the resource pool proxy server 501 is 01, the protocol translation server 1 may search whether a channel identifier matching the second virtual terminal number 01 exists in the stored channel identifiers.

Step 708: and under the condition that the matched channel identification exists, the cooperative conversion server determines that a video transmission channel exists between the cooperative conversion server and the resource pool proxy server.

In the embodiment of the present invention, in the case that there is a matching channel identifier, the coordination server 502 determines that there is a video transmission channel between the coordination server and the resource pool proxy server.

For example, for the above example, if the second virtual terminal number corresponding to the resource pool proxy server 501 is 01, and if the coordination server 1 finds the channel identifier matching with the second virtual terminal number 01 in the stored channel identifiers, the coordination server 1 determines that a video transmission channel exists between the coordination server and the resource pool proxy server.

Step 709: and under the condition that the matched channel identification does not exist, the cooperative conversion server determines that a video transmission channel does not exist between the cooperative conversion server and the resource pool proxy server.

In the embodiment of the present invention, in the case that there is no matching channel identifier, the coordination server 502 determines that there is no video transmission channel between it and the resource pool proxy server 501.

For example, for the above example, if the second virtual terminal number corresponding to the resource pool proxy server 501 is 01, if the channel identifier matching the second virtual terminal number 01 is not found in the stored channel identifiers by the cooperative transfer server 1, the cooperative transfer server 1 determines that no video transmission channel exists between the cooperative transfer server and the resource pool proxy server.

In the embodiment of the invention, the channel identifier is set for the existing video transmission channel, so that whether the video transmission channel exists can be quickly judged through the channel identifier.

In this embodiment of the present invention, optionally, after the cooperative server generates a video transmission channel between the cooperative server and the resource pool proxy server in the case that no video channel exists, the method may further include: the protocol conversion server sets a channel identifier for the generated video transmission channel; the channel identifier includes: a first virtual terminal number of the protocol conversion server and a second virtual terminal number of the resource pool proxy server; and the cooperative conversion server stores the channel identifier.

Specifically, in the absence of a video channel, after the cooperative conversion server 502 generates a video transmission channel between the cooperative conversion server 502 and the resource pool proxy server 501, the cooperative conversion server 502 may set a channel identifier for the generated video transmission channel, and the channel identifier may also include: the first virtual terminal number of the protocol conversion server 502 and the second virtual terminal number of the resource pool proxy server 501, the protocol conversion server 502 may store the channel identifier, which is equivalent to updating the channel identifier of the existing video transmission channel in the protocol conversion server 502, and further in subsequent applications, the generated video transmission channel may be used as the existing video transmission channel, which is convenient for searching and determining.

Step 710: and under the condition that a video channel exists, the coordination server sends the target video with the identity mark to the resource pool proxy server through the existing video transmission channel.

Step 711: and under the condition that no video channel exists, the cooperative conversion server generates a video transmission channel between the cooperative conversion server and the resource pool proxy server, and sends the target video provided with the identity identifier to the resource pool proxy server through the generated video transmission channel.
