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 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 embodiment of the application is provided, a flow probe is connected to a ground switch which is connected between a main server and the ground server and used for audio and video stream transmission, the ground switch mirrors audio and video stream data to the flow probe, the flow probe extracts an audio and video stream data packet from the audio and video stream data, and audio bit rate data and video code rate data carried in the audio and video stream data packet are analyzed to obtain flow information, the flow information is provided with an information identifier corresponding to the ground server, and a display terminal displays the flow information based on the information identifier, so that operation and maintenance personnel can visually know the flow data of the national trunk bandwidth occupied by each ground server on the display terminal.

Example one

Referring to fig. 5, a flow chart of steps of embodiment 1 of a streaming data analysis system according to the present application is shown, where the streaming data analysis system according to the present application may be applied to a video network, the system includes a main server 501, a plurality of floor switches 502 communicatively connected to the main server 501, a floor server 503 and a traffic probe 504 connected to the floor switches 502, and a display terminal 505 simultaneously connected to the plurality of traffic probes 504, where the floor server 503 has a floor server 503 identifier.

In practice, the main server 501 may be understood as a central operator server, each floor server 503 is deployed in each province, one floor server 503 is deployed in each province, a network bandwidth between the main server 501 and each floor server 503 is a trunk bandwidth, audio and video services across provinces all need to occupy the trunk bandwidth, and the main server 501 and the floor servers 503 communicate with each other through the floor switches 502, so that one traffic probe 504 is deployed on each floor switch 502, and stream data targeted by the traffic probe 504 is stream data in the trunk bandwidth. The identifier of the landing server 503 may be a number of the landing server 503, or may be a geographical name of a location where the landing server 503 is located, and in practice, the identifier may be flexibly set according to actual situations.

The floor switch 502 is configured to transmit first audio/video stream data between the main server 501 and the floor server 503, and mirror the first audio/video stream data into second audio/video stream data.

In practice, the floor server 503 is connected to a certain port of the floor switch 502 through a network cable, all audio/video stream data of the floor server 503 can pass through the port, the floor switch 502 mirrors the first audio/video stream data of the port, and the mirrored second audio/video stream data is a copy identical to the first audio/video stream data.

The flow probe 504 is configured to receive the second audio/video stream data sent by the switch 502, extract an audio/video stream data packet from the second audio/video stream data, analyze audio bit rate data and video code rate data in the audio/video stream data packet, and encapsulate the audio bit rate data and the video code rate data into first flow information; wherein, the first traffic information has a first information identifier corresponding to the identifier of the landing server 503.

In practice, the audio/video stream data packet can be captured from the second audio/video stream data by using the existing packet capturing technology on the flow probe 504, and in the specific implementation, the audio/video stream data packet can be captured once every 10 seconds, so that the purpose of monitoring the flow in the bandwidth of the national trunk in real time is achieved. When the audio and video stream data packet is analyzed, the audio stream data and the video stream data are included in the captured audio and video stream data packet, the flow probe 504 can analyze the audio bit rate data by using the existing audio data analysis technology, and can analyze the video code rate data by using the existing video data analysis technology. The audio bit rate data represents the data volume transmitted by the audio stream for one second, and the video code rate data represents the data volume transmitted by the video stream for one second, so that the flow information is obtained by analyzing the audio bit rate data and the video code rate data.

The traffic probe 504 may encapsulate the audio bit rate data and the video bit rate data into first traffic information by using an existing information encapsulation technology, and mark the first information with a first information identifier corresponding to the identifier of the landing server 503, where in practice, the first information identifier may be the same as the identifier of the landing server 503, or may be another identifier having the same meaning as the identifier of the landing server 503, for example, if the server identifier is north-river, then the first information identifier may be a wing.

For example, the traffic probe 504 can analyze that the audio bit rate data of the landing server 503 is 128kbps, the video bitrate data is 600kbps, and the first traffic information can be expressed as Rec128kbps and camera600kbps in Hebei province. Of course, in specific implementations, the first traffic information of the traffic probe 504 may be the sum of the audio bit rate data and the video rate data, for example, 728kbps in north Hebei province, which indicates that the traffic in the national trunk bandwidth of north Hebei province is 728 kbps.

The display terminal 505 is configured to receive the first traffic information sent by the traffic probe 504, and display the first traffic information based on the first information identifier.
