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, the monitoring video processing scheme provided by the embodiment of the invention follows the protocol of the video network, can check the monitoring video more conveniently and ensure the safety of the monitoring video.

The monitoring video processing method of the embodiment of the invention can be applied to the video network. The video network comprises a streaming media server, a video network server (which can be the node server) and a collaboration server, and the internet comprises a browser and a plurality of monitoring devices. The browser can be installed on a PC (personal computer), a mobile phone, a tablet computer and the like. The monitoring device can be various network cameras and other devices.

The streaming media server can be understood as a gateway, and can realize the interaction between the internet and the video network. The streaming media server may include two network cards, one network card facing the internet side for communication connection with the browser, and the other network card facing the video networking side for communication connection with the video networking server. The streaming media server can be registered on the video network server in a terminal mode, and the streaming media server can be networked to perform normal services when being accessible after the registration. The successfully registered rear view network server may allocate information such as a view network number, a view network Address, and a Media Access Control (MAC) Address to the streaming Media server. The streaming media server can be distinguished in the video network by the video network number of the streaming media server and the like.

The protocol conversion server can be understood as a gateway, and the protocol conversion server can be connected with a plurality of external monitoring devices and is responsible for accessing the monitoring devices on the internet into the video network. The protocol conversion server can comprise two network cards, one network card faces to the internet side and is used for being in communication connection with the monitoring equipment, and the other network card faces to the video networking side and is used for being in communication connection with the video networking server. The protocol conversion server can be registered on the video network server in a terminal mode, and the network is connected to perform normal service when the protocol conversion server can be accessed after the protocol conversion server is registered. After the successful registration, the video networking server can allocate information such as a video networking number, a video networking address, an MAC address and the like for the protocol conversion server. The protocol conversion server can be distinguished in the video network through the video network number of the protocol conversion server and the like.

Referring to fig. 5, a flowchart illustrating steps of a surveillance video processing method according to an embodiment of the present invention is shown.

The monitoring video processing method of the embodiment of the invention can comprise the following steps:

step 501, a streaming media server receives an internet protocol request packet sent by the browser through the internet, where the internet protocol request packet includes a monitoring identifier to be checked.

Background services and databases may also be included in the internet. The background service may be Mserver. The browser may be communicatively coupled with a background service.

The coordination server may store information of each connected monitoring device, for example, may store a monitoring device list, where the monitoring device list may include a device identifier and a group identifier to which the device belongs, and may also include information such as a device name, a monitoring number, and a geographic location (e.g., longitude and latitude).

The background service can be in communication connection with the collaboration server. The background service can acquire the monitoring equipment list from the cooperative server through the internet and store the monitoring equipment list into the database. Because the monitoring devices may change, such as whether to delete the monitoring devices, whether to add new monitoring devices, and the like, and the corresponding monitoring device list also changes, the background service may periodically synchronize the monitoring device list in the collaboration server so as to update in time.

Therefore, the method of the embodiment of the present invention may further include: the background service periodically sends a list synchronization request to the co-rotation server; after receiving the list synchronization request, the protocol conversion server acquires a monitoring equipment list aiming at the list synchronization request and returns the monitoring equipment list to the background service; and the background service receives a monitoring equipment list returned by the protocol conversion server aiming at the list synchronization request, and synchronously updates the monitoring equipment list to the database. The periodic time may be set to any suitable value, such as 1 day, 1 week, etc., and the embodiment of the present invention is not limited thereto.

When a user wants to view a monitoring video collected by monitoring equipment on a browser, a monitoring equipment list can be obtained through the browser. Therefore, the method of the embodiment of the present invention may further include: the browser sends a list acquisition request to a background service; after receiving the list acquisition request, the background service acquires a monitoring equipment list from the database according to the list acquisition request and returns the monitoring equipment list to the browser; and the browser receives the monitoring equipment list returned by the background service aiming at the list acquisition request and displays the monitoring equipment list.

The monitoring device list includes device identifications and group identifications to which the devices belong. The method includes the steps that a user can select a device to be checked from a monitoring device list, a browser obtains a device identifier to be checked and a group identifier to which the device to be checked belongs according to the selection of the user, and the device identifier to be checked and the group identifier to which the device to be checked belongs serve as the monitoring identifier to be checked. The browser obtains an internet protocol request packet based on internet protocol encapsulation, and the internet protocol request packet can include a monitoring identifier to be viewed. The IP request packet includes an internet packet header, which may include information such as an IP address of a browser (source terminal), an IP address of a relay server (destination terminal), and the like.

The browser sends the internet protocol request packet to the streaming media server through the internet. The internet protocol request packet is transmitted based on the internet protocol.

Step 502, the streaming media server converts the internet protocol request packet into an internet protocol request packet.

And after receiving the Internet protocol request packet, the streaming media server converts the Internet protocol request packet into an Internet protocol request packet.

In an implementation, the step of converting the internet protocol request packet into the video internet protocol request packet by the streaming media server may include: the streaming media server adds a first video network packet header based on a video network protocol to an Internet protocol request packet to obtain the video network protocol request packet.

The first video network packet header of the video network protocol request packet comprises transmission path information of the video network protocol request packet in the video network. The transmission path information may include information such as a video network address of a streaming server (source terminal), a MAC address of the streaming server, a video network address of a protocol server (destination terminal), and a MAC address of the protocol server. Of course, the first video network header may further include information such as a video network number of the streaming media server, a video network number of the protocol server, and related information of the video network protocol, such as information such as an internal operation code of the video network protocol.

Step 503, the streaming media server sends the video networking protocol request packet to the protocol conversion server through the video networking via the video networking server.

The streaming media server sends the converted video networking protocol request packet to the video networking server through the video networking, and then the video networking server forwards the video networking protocol request packet to the protocol conversion server.

In an alternative embodiment, the video networking server may send the video networking protocol request packet to the protocol conversion server over a downlink communication link configured to the protocol conversion server.

In practical applications, the video network is a network with a centralized control function, and includes a master control server and a lower level network device, where the lower level network device includes a terminal, and one of the core concepts of the video network is to configure a table for a downlink communication link of a current service by notifying a switching device by the master control server, and then transmit a data packet based on the configured table.

Namely, the communication method in the video network includes:

and the master control server configures the downlink communication link of the current service.

And transmitting the data packet of the current service sent by the source terminal to the target terminal according to the downlink communication link.

In the embodiment of the present invention, configuring the downlink communication link of the current service includes: and informing the switching equipment related to the downlink communication link of the current service to allocate the table.

Further, transmitting according to the downlink communication link includes: the configured table is consulted, and the switching equipment transmits the received data packet through the corresponding port.

In particular implementations, the services include unicast communication services and multicast communication services. Namely, whether multicast communication or unicast communication, the core concept of the table matching-table can be adopted to realize communication in the video network.

As mentioned above, the video network includes an access network portion, in which the master server is a node server and the lower-level network devices include an access switch and a terminal.

For the unicast communication service in the access network, the step of configuring the downlink communication link of the current service by the master server may include the following steps:

and a substep S11, the main control server obtains the downlink communication link information of the current service according to the service request protocol packet initiated by the source terminal, wherein the downlink communication link information includes the downlink communication port information of the main control server and the access switch participating in the current service.

In the substep S12, the main control server sets a downlink port to which a packet of the current service is directed in a packet address table inside the main control server according to the downlink communication port information of the main control server; and sending a port configuration command to the corresponding access switch according to the downlink communication port information of the access switch.

In sub-step S13, the access switch sets the downstream port to which the packet of the current service is directed in its internal packet address table according to the port configuration command.

For a multicast communication service (e.g., video conference) in the access network, the step of the master server obtaining downlink information of the current service may include the following sub-steps:

in sub-step S21, the main control server obtains a service request protocol packet initiated by the target terminal and applying for the multicast communication service, where the service request protocol packet includes service type information, service content information, and an access network address of the target terminal.

Wherein, the service content information includes a service number.

And a substep S22, the main control server extracts the access network address of the source terminal in a preset content-address mapping table according to the service number.

In the substep of S23, the main control server obtains the multicast address corresponding to the source terminal and distributes the multicast address to the target terminal; and acquiring the communication link information of the current multicast service according to the service type information and the access network addresses of the source terminal and the target terminal.

Step 504, the streaming media server receives a video networking protocol data packet returned by the protocol conversion server through the video networking, wherein the video networking protocol data packet includes a monitoring video acquired by the monitoring device corresponding to the monitoring identifier to be checked.

The monitoring equipment and the protocol conversion server can perform bidirectional interaction based on an internet protocol. The monitoring equipment collects monitoring videos and packages the monitoring videos based on the Internet protocol to obtain Internet protocol data packets. The protocol conversion server can obtain the internet protocol data packet obtained by the encapsulation of the monitoring equipment.

After receiving the video networking protocol request packet, the protocol conversion server analyzes the video networking protocol request packet to obtain a monitoring identifier to be checked, namely an equipment identifier to be checked and a group identifier to which the equipment to be checked belongs. The protocol conversion server obtains an internet protocol data packet obtained by packaging the collected monitoring video by the monitoring equipment corresponding to the monitoring identifier to be checked, and sets information such as an IP address of the protocol conversion server (source terminal) and an IP address of a browser (destination terminal) in an internet packet header of the internet protocol data packet. And the protocol conversion server adds a second video network packet header to the Internet protocol data packet corresponding to the monitoring identifier to be checked to obtain a corresponding video network protocol data packet.

And the second video network packet header of the video network protocol data packet comprises transmission path information of the video network protocol data packet in the video network. The transmission path information may include information such as a video network address of a protocol conversion server (source terminal), a MAC address of the protocol conversion server, a video network address of a streaming server (destination terminal), and a MAC address of the streaming server. Of course, the second video network packet header may further include information such as a video network number of the streaming media server, a video network number of the protocol server, and related information of the video network protocol, such as information such as an internal operation code of the video network protocol.

The protocol data packet of the video networking is sent to the video networking server by the protocol conversion server through the video networking, and then the video networking server forwards the protocol data packet of the video networking to the streaming media server.

In an alternative embodiment, the video networking server may send the video networking protocol data packet to the streaming media server according to a downstream communication link configured for the streaming media server.

Step 505, the streaming media server converts the video networking protocol data packet into an internet protocol data packet.

The streaming media server receives a video networking protocol data packet returned by the protocol conversion server through the video networking, and converts the video networking protocol data packet into an internet protocol data packet.

In an implementation, the step of converting the video networking protocol data packet into the internet protocol data packet by the streaming media server may include: and the streaming media server deletes the second video network packet header in the video network protocol data packet to obtain the internet protocol data packet.

Step 506, the streaming media server returns the internet protocol data packet to the browser through the internet, so as to play the monitoring video in the browser.

The streaming media server returns the internet protocol data packet to the browser through the internet, the browser can call a decoder to analyze the internet protocol data packet to obtain a monitoring video acquired by monitoring equipment corresponding to the monitoring identifier to be checked, and call a player to play the monitoring video through an H5 page.

In an implementation, the Streaming server may return the internet protocol packets to the browser in the form of HLS (HTTP Live Streaming) slices. HLS is a streaming media network transport Protocol based on HTTP (Hyper Text Transfer Protocol), and its working principle is to divide the whole stream into small HTTP-based files for downloading, only a few of them at a time. While the media stream is playing, the client may choose to download the same resource from many different alternate sources at different rates, allowing the streaming media session to accommodate different data rates.

According to the embodiment of the invention, the monitoring video collected by the monitoring equipment can be checked through the browser, so that the checking and monitoring are more convenient and fast, and the monitoring is not limited by the faults of the equipment such as a display and the like; and the monitoring video is transmitted in the video network, the protocol conversion between the video network and the internet is carried out through the streaming media server, the video network belongs to a special network, and equipment which is not registered and authorized in the video network cannot access the video network, so that the safety of the monitoring video can be ensured.
