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 characteristics of the video network, one of the core concepts of the embodiment of the invention is provided, the set top box of the local terminal requests the server to control the camera connected with the set top box of the opposite terminal, and the server commands the set top box of the opposite terminal to receive and adjust the camera according to the request, according to the protocol of the video network.

Referring to fig. 5, a flowchart of steps of a concurrent on-demand processing method based on a video network according to the present invention is shown, where the method may be applied to a video network, where the video network includes a video network monitoring and networking management and scheduling platform, and the video network monitoring and networking management and scheduling platform includes a video network device access server and a multi-stage monitoring platform communicatively connected to the video network device access server, and specifically includes the following steps:

step 510, when receiving the on-demand request sent by the user, the monitoring platform sends a request for obtaining resources of the video network to the access server of the video network device.

The monitoring platform and the access server of the video networking equipment are in communication connection through heartbeat, so that the monitoring platform and the access server of the video networking equipment can be in real-time communication, the monitoring platform detects the current resource availability of the access server of the video networking equipment through the heartbeat and compares the current resource availability with a preset threshold value, and the on-demand service of a user can be controlled in real time.

In step 520, the access server of the video networking device receives the video networking resource obtaining requests respectively sent by the multi-stage monitoring platform.

The video network equipment access server can communicate with the multistage monitoring platform, and when the multistage monitoring platform communicates with the video network equipment access server, the video network equipment access server can receive video network resource acquisition requests respectively sent by the multistage monitoring platform.

The multi-level monitoring platform refers to a multi-level monitoring platform, and includes a plurality of monitoring platforms, and the monitoring platforms may be in a relationship between upper and lower levels. In addition, the video networking resource in the embodiment of the invention can be a video networking virtual number.

Step 530, the access server of the video network device detects the current available video network resource amount and sends feedback information to the monitoring platform.

Wherein the feedback information comprises the amount of available video networking resources.

When the access server of the video networking equipment receives video networking resource acquisition requests respectively sent by multiple levels of monitoring platforms, in order to distribute video networking resources in a balanced manner and avoid the problem that if the video networking resources are excessively seized by the multiple levels of monitoring platforms when monitoring the same cooperative monitoring is carried out under the condition of large monitoring concurrency, the video networking equipment access server may have the problem of on-demand failure and further influence the monitoring service of the monitoring platforms, in the embodiment of the invention, the access server of the video networking equipment needs to detect the current available video networking resource amount and send feedback information to the monitoring platforms. The amount of available video network resources refers to the amount of video network resources that can be currently allocated and utilized, such as the total number of currently available video network virtual numbers.

Specifically, as shown in fig. 6, step S530 may specifically include the following steps:

step 531, the access server of the video networking device obtains the total number of the current video networking virtual numbers and the used total number of the video networking virtual numbers.

Step 532, the access server of the video networking device differentiates the total number of the current video networking virtual numbers from the used total number of the video networking virtual numbers to obtain the available video networking virtual numbers, and the available video networking virtual numbers are used as the available video networking resource amount.

The embodiment of the invention takes the video networking resources as the video networking virtual numbers as an example for explanation, and the video networking equipment calculates the available video networking virtual numbers by acquiring the total number of the current video networking virtual numbers and the used total number of the video networking virtual numbers, and takes the available video networking virtual numbers as the amount of the available video networking resources.

And 540, the monitoring platform receives feedback information sent by the access server of the video networking equipment.

And step 550, the monitoring platform performs on-demand control on the on-demand request sent by the user according to the amount of available video networking resources.

The embodiment of the invention can effectively control the on-demand request sent by the user according to the amount of the available video networking resources. For example, an alarm may be raised when the amount of available video networking resources is insufficient.

Specifically, as shown in fig. 7, the step may include the following steps:

step S551, the monitoring platform judges whether the quantity of the available video networking resources is less than a preset threshold value;

in step S552, the monitoring platform sends out an alarm prompt message when determining that the amount of the available video networking resource is less than the preset threshold.

The available video networking resource quantity is compared with a preset threshold value, whether the current available video networking resource quantity can meet the on-demand requirement of the current user can be effectively judged, and when the available video networking resource quantity is not enough, warning information is timely sent out, so that the video networking resource is prevented from being excessively occupied.

The concurrent on-demand processing method based on the video networking provided by the embodiment of the invention carries out real-time communication between the monitoring platform and the video networking equipment access server, when the monitoring platform receives an on-demand request sent by a user, the monitoring platform sends a video networking resource acquisition request to the video networking equipment access server, and the video networking equipment access server sends feedback information to the monitoring platform by detecting the current available video networking resource amount, so that the monitoring platform carries out on-demand control on the on-demand request sent by the user by receiving the feedback information sent by the video networking equipment access server. Therefore, under the condition of large monitoring concurrency, when the multi-stage monitoring platform monitors the same video networking equipment to be accessed to the server for monitoring, the problem of possible video-on-demand failure caused by excessive occupation of available video networking resources is avoided, and further the monitoring business of the monitoring platform can be prevented from being influenced.

It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.
