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:

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.

The resourcepool proxy server 502 may obtain an analysis rule and the like corresponding to the flow adjustment instruction, and the resourcepool proxy server 502 may analyze the flow adjustment instruction based on the corresponding analysis rule to obtain an agent virtual terminal number corresponding to the flow adjustment instruction.

In the embodiment of the present invention, the setting format of the stream adjustment command, the corresponding analysis rule, and the like are not particularly limited.

The actual virtual terminal number may be used to uniquely identify the corotation server. The actual virtual terminal number may be the MAC address of the assistance server, or the like. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the present invention, the resourcepool proxy server 502 serves as a proxy party of eachcoordination server 503, and the resourcepool proxy server 502 stores a corresponding relationship between a proxy virtual terminal number and an actual virtual terminal number of each coordination server, so that a coordination server corresponding to a corresponding actual virtual terminal number can be accurately and conveniently found by using the proxy virtual terminal number, and the coordination server corresponding to the actual virtual terminal number is determined as a target coordination server.

For example, referring to fig. 5, if the proxy virtual terminal number set by the resourcepool proxy server 502 for the collaboration server 1 is: 11, if the actual virtual terminal number of the collaboration server 1 is: 21, the resourcepool proxy server 502 may store the corresponding relationship between the proxy virtual terminal number 11 of the transfer server 1 and the actual virtual terminal number 21, and further, by using the corresponding relationship, the transfer server 1 actually corresponding to the proxy virtual terminal number 11 may be accurately and quickly determined.

For example, referring to fig. 5, if the resourcepool proxy server 502 receives a stream modulation instruction sent by the video subscriber terminal 1, if the stream modulation instruction includes a proxy virtual terminal number: and 11, the proxy virtual terminal number 11 is the proxy virtual terminal number.

In this embodiment of the present invention, the target coordination server may obtain the target video corresponding to the stream adjustment instruction from at least onevideo capture terminal 504 bound to the target coordination server based on a video network or an internet.

For example, for the above example, the target coordination server 1 may obtain the target video corresponding to the stream modulation instruction from at least one video capture terminal among the video capture terminals 1 to n bound to the target coordination server 1 through a video network.

In the embodiment of the present invention, optionally, the target coordination server may obtain the target video corresponding to the stream adjustment instruction from at least onevideo acquisition terminal 504 bound to the target coordination server based on the video network, and by virtue of the advantage of the large bandwidth of the video network, thecoordination server 503 may further obtain the target video quickly.

Step 607: and the target coordination server sends the target video to the resource pool proxy server through the video transmission channel corresponding to the channel identifier.

In this embodiment of the present invention, thecoordination server 503 may send the target video to the resourcepool proxy server 502 through a video transmission channel corresponding to the channel identifier.

In the embodiment of the invention, the video transmission channel is specially used for transmitting videos, and the videos are distinguished from other video networking resources, instructions and the like by the video transmission channel and are specially transmitted, so that the real-time performance of target video transmission can be improved.

For example, for the above example, the target collaboration server 1 may send the above target video to the resourcepool proxy server 502 through the video transmission channel corresponding to the channel identifier.

In this embodiment of the present invention, optionally, if a video transmission channel corresponding to the channel identifier already has a video transmission task, thecooperative conversion server 503 may add the target video to the video transmission queue, manage the video transmission queue using a first-in first-out mode or according to a certain priority, and send the target video to the resourcepool proxy server 502.

Referring to fig. 7, it is a flowchart of steps of another video acquisition method according to the present invention, where the method may be applied to the video network, and for the related description of the video network, reference may be made to the related description above and fig. 5, etc., and details are not repeated here to avoid repetition. Specifically, the method may include steps 701-710:

step 701: the video subscription terminal sends a stream adjusting instruction to the resource pool proxy server; the flow adjusting instruction comprises: proxy virtual terminal number; the flow adjusting instruction further comprises: identifying a video acquisition terminal; and the proxy virtual terminal number is used for identifying each coordination server in the video subscription terminal and the resource pool proxy server.

In this embodiment of the present invention, thestep 701 may refer to thestep 601, and it should be noted that the stream adjustment instruction may further include a video capture terminal identifier, where the video capture terminal identifier is used to identify or distinguish different video capture terminals, and the video capture terminal identifier may be a MAC address of the video capture terminal, and this is not particularly limited in this embodiment of the present invention.

In the embodiment of the present invention, optionally, thevideo subscriber terminal 501 may send the stream adjustment instruction to the resourcepool proxy server 502 based on the video network, and because the video network has the advantage of a large bandwidth, thevideo subscriber terminal 501 may further send the stream adjustment instruction to the resourcepool proxy server 502 quickly.

Step 702: and the resource pool proxy server analyzes the flow adjusting instruction and acquires a proxy virtual terminal number corresponding to the flow adjusting instruction.

Step 703: and the resource pool proxy server determines a video transmission channel corresponding to the stream adjusting instruction according to the proxy virtual terminal number and acquires a channel identifier corresponding to the video transmission channel.

Step 704: and the resource pool proxy server determines an actual virtual terminal number corresponding to the proxy virtual terminal number according to the corresponding relation between the proxy virtual terminal number and the actual virtual terminal number, and determines a transfer server corresponding to the actual virtual terminal number as a target transfer server.

Step 705: and the resource pool proxy server forwards the flow adjusting instruction and the channel identifier to the target coordination server.

In the embodiment of the present invention, thesteps 702 to 705 may refer to the related descriptions of thesteps 602 to 705, respectively, and are not described herein again to avoid repetition.

Step 706: and the target coordination and conversion server acquires a target video corresponding to the stream adjusting instruction from a target video acquisition terminal corresponding to the video acquisition terminal identification.

In the embodiment of the invention, the stream adjusting instruction further comprises the video acquisition terminal identification, so that the stream adjusting instruction accurately indicates which videos acquired by the video acquisition terminals are acquired, and the target transfer server only needs to acquire the target video from the target video acquisition terminal corresponding to the video acquisition terminal identification.

In this embodiment of the present invention, under the condition that the stream modulation instruction further includes a video capture terminal identifier, thetarget coordination server 503 may obtain a target video corresponding to the stream modulation instruction from a target video capture terminal corresponding to the video capture terminal identifier.

For example, as shown in fig. 5, if the determined target cooperative transmission server is the cooperative transmission server 1, and if the stream tuning instruction only includes the identifier of the video capture terminal 1, the cooperative transmission server 1 only needs to obtain the target video from the video capture terminal 1, and does not need to obtain the video from the video capture terminal 2 to the video capture terminal n, so that the efficiency of obtaining the target video is high, and the efficiency of obtaining the target video can be further improved.

Step 707: and the target coordination server adds the target video to a video list to be sent corresponding to the channel identifier.

In the embodiment of the present invention, eachcoordination server 503 may be provided with a to-be-sent video list corresponding to the channel identifier, and all video names or video identifiers that need to be sent through the video transmission channel are recorded in the to-be-sent list in real time.

In the embodiment of the present invention, after the target video is obtained, the target coordination server may add the target video to the video list to be sent corresponding to the channel identifier, and specifically, the target coordination server may record or add a name or an identifier of the target video to the video list to be sent corresponding to the channel identifier.

For example, for the above example, if the target corotation server is the corotation server 1, after the corotation server 1 acquires the target video, the corotation server 1 may record the name or the identifier of the target video into a to-be-transmitted video list that needs to be transmitted by a video transmission channel corresponding to the channel identifier.

Step 708: and the target co-rotation server determines the to-be-sent sequence of the target video in the to-be-sent video list according to a preset rule.

In the embodiment of the present invention, the preset rule may be determined according to actual needs, for example, the preset rule may determine the order of the target video to be sent in the video list to be sent in real time by setting corresponding weights according to the importance degree or priority degree of the video subscriber terminal corresponding to the target video, or according to the size of the target video, the waiting time of the target video, and the like, or by setting corresponding weights for the importance degree or priority degree of the video subscriber terminal corresponding to the target video, the size of the target video, the waiting time of the target video, and the like, and determining the weighted sum of each factor. In the embodiment of the present invention, the preset rule is not particularly limited.

In this embodiment of the present invention, beforestep 708, optionally, the method may further include: the target collaboration server acquires the priority level of the video subscription terminal; the target cooperative conversion server acquires the size of the target video; the target cooperative conversion server acquires the sending waiting time of the target video; the target cooperative conversion server determines a sending score of the target video based on the priority level, the size of the target video and the sending waiting time of the target video; the target corotation server determines a to-be-sent sequence of the target video in the to-be-sent video list according to a preset rule, and the method comprises the following steps: the target cooperative conversion server sorts the sending scores of all videos in the video list to be sent according to a sequence from high to low to obtain the position sequence of the target videos in the video list; and the target coordination server determines the position sequence of the target video in the video list as the sequence of the target video to be sent in the video list to be sent.

Specifically, the target coordination transfer server may obtain the priority level of the video subscription terminal corresponding to the target video, the size of the target video, the sending waiting time of the target video, and the like, and the target coordination transfer server may obtain the subscription terminal identifier corresponding to the target video and the like from the stream tuning instruction, and find the priority level of the subscription terminal corresponding to the target video in the correspondence between the subscription terminal identifier and the priority level according to the subscription terminal identifier corresponding to the target video and the like. The target collaboration server may obtain the size of the target video from a configuration file of the target video, and the like. The target coordination server can record the acquisition time of the target video while acquiring the target video from the video acquisition terminal, and determine the sending waiting time of the target video in real time by taking the acquisition time of the target video as a starting point. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the invention, the sending score of the target video can be determined according to the priority level of the video subscription terminal corresponding to the acquired target video, the size of the target video, the sending waiting time of the target video and the like. Specifically, the respective weights may be set for the respective factors, a weighted sum of the three factors, and the like may be calculated, and the weighted sum and the like may be used as the transmission score.

For example, if it is to be ensured that the subscribing terminal with the high priority receives the target video in time as much as possible, the weight of the factor of the priority of the video subscribing terminal corresponding to the target video may be set to be larger, so as to ensure that the subscribing terminal with the high priority receives the target video in time.

In the embodiment of the present invention, the target cooperative transmission server may obtain, by analogy, the transmission score of each video in the to-be-transmitted video list corresponding to the channel identifier according to the manner described above, where the transmission score of each video may represent the urgency degree that each video needs to be transmitted in time, and the like, for example, if the transmission score of the video a is high, the urgency degree that the video a needs to be transmitted in time may be represented as high. The target corotation server may rank the sending scores of the videos according to a sequence from high to low, so as to obtain a position sequence of the target video in the to-be-sent video list corresponding to the channel identifier, and the target corotation server may determine the position sequence of the target video in the to-be-sent video list corresponding to the channel identifier as the to-be-sent sequence of the target video in the to-be-sent video list.

For example, the channel identifier included in the stream tuning instruction is B1, if there are 5 videos to be sent in the video transmission channel corresponding to the channel identifier B1, the target collaboration server calculates the sending scores of the 5 videos according to the above manner, sorts the 5 videos according to the order of sending scores from high to low, and the position order of the target video in the 5 videos may be the order of sending the target video in the video list to be sent. If the position sequence of the target video in the 5 videos is the third, the sequence of the target video to be sent in the video list to be sent may be the third.

In the embodiment of the invention, a target cooperative conversion server acquires the priority level of a video subscription terminal, the target cooperative conversion server acquires the size of a target video, the target cooperative conversion server acquires the sending waiting time of the target video, and the target cooperative conversion server determines the sending value of the target video based on the priority level, the size of the target video and the sending waiting time of the target video; the target cooperation server sorts the sending scores of all videos in the video list to be sent according to a sequence from high to low to obtain the position sequence of the target videos in the video list; the target cooperation server determines the position sequence of the target video in the video list as the to-be-sent sequence of the target video in the to-be-sent video list, so that the to-be-sent video in each video transmission channel can be efficiently and accurately managed, meanwhile, the sending sequence of the to-be-sent video in each video transmission channel is managed in a personalized mode, not only can actual requirements be met, but also the load balance of the video transmission channels can be achieved.

Step 709: and the target coordination server sends the target video to the resource pool proxy server through the video transmission channel corresponding to the channel identifier based on the sequence to be sent.

In this embodiment of the present invention, step 709 may refer to the related description ofstep 607, and it should be noted that, based on the to-be-sent sequence, the target collaboration server may send the target video to the resource pool proxy server through the video transmission channel corresponding to the channel identifier.

For example, for the above example, if the order of the target video to be sent in the video list to be sent is third, the target coordination server may use the target video as the third video to be sent, and send the target video to the resource pool proxy server through the video transmission channel corresponding to the channel identifier.

Step 710: and the resource pool proxy server forwards the target video to the video subscription terminal.

In the embodiment of the present invention, step 710 may refer to the description related to step 608, and is not described herein again to avoid repetition.

In the embodiment of the present invention, optionally, the video subscription terminal and the resource pool proxy server, the resource pool proxy server and the target transfer server, and the target transfer server and the video capture terminal are all in communication through a video network.
