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 data packets, and is 64 bytes if the data packet is a variety of protocol packets, and is 32+1024 or 1056 bytes if the data packet is a unicast data 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.

The terminal of the video network needs to be registered on the video network server to carry out normal service.

The firmware upgrade notification may include an identification of the end of the video network (e.g., a user number), a MAC address of the end of the video network, a name of the firmware, version information of the firmware, etc. Optionally, the video network server may send the firmware upgrade notification to the video network terminal according to a downlink communication link configured for the video network terminal through the video network.
In one specific implementation, the video network server may encapsulate the firmware upgrade notification into a first video network protocol data packet based on a first video network protocol, and achieve the purpose of sending the firmware upgrade notification by sending the first video network protocol data packet.
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.

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.

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.

The firmware upgrade request may include an identification of the end of the video network (e.g., a user number), a MAC address of the end of the video network, a name of the firmware, etc. And the video network server analyzes the second video network protocol data packet after receiving the second video network protocol data packet, acquires corresponding firmware aiming at the firmware upgrading request, packages the acquired firmware into a third video network protocol data packet based on a third video network protocol, and sends the third video network protocol data packet to the video network terminal through the video network.
After downloading the firmware from the video network server, the video network terminal modifies the name of the firmware into a format including version information. For example, for the firmware corresponding to the camera, after the firmware is downloaded from the video network server, the name of the firmware is the original name CAM0_ v0.mrg, and the original name does not include the version information corresponding to the firmware, the name may be modified to CAM0_ v2.3.8.mrg, where 2.3.8 represents the version information of the firmware. For the firmware corresponding to the HDMI device, if the name of the firmware is the original name CAM1_ v1.mrg after being downloaded from the video network server, the name can be modified to CAM1_ v2.3.7.mrg, where 2.3.7 represents the version information of the firmware.
And after the firmware name is modified, the video network terminal stores the downloaded firmware into a preset directory according to the modified name. The preset directory is a preset directory for storing files downloaded from the video network server by the video network terminal. For example, the preset directory may be setting/data/vv/uvc/. The downloaded file may include firmware corresponding to an external device of the video network terminal, a file corresponding to the video network terminal itself, and the like.
The terminal of the video network can start the firmware upgrading program after downloading the firmware, for example, the firmware upgrading program can be an update _3516 program. The firmware upgrade program may be stored in the preset directory, or may be stored in another directory, which is not limited in this embodiment of the present invention.
After the firmware upgrading program is started, the downloaded firmware can be searched from the preset directory. In a specific implementation, the names of different types of files correspond to different suffixes, so that the preset directory can be traversed, a file indicated as firmware by the suffix is searched, and the searched file is the downloaded firmware. For example, the suffix corresponding to the firmware name is mrg, so that the preset directory/data/vv/uvc/, from which a file with the suffix mrg is searched, can be traversed, and the searched file with the suffix mrg is the downloaded firmware.
After the downloaded firmware is found, because the names of the firmware are modified after the downloaded firmware is downloaded, whether the firmware currently used by the external equipment corresponding to the downloaded firmware needs to be updated can be determined according to the names of the downloaded firmware.
In a specific implementation, the step of determining whether the firmware currently used by the external device corresponding to the downloaded firmware needs to be updated according to the name of the downloaded firmware may include: the video network terminal extracts the version information of the downloaded firmware from the name of the downloaded firmware and reads the version information of the firmware currently used by the external equipment corresponding to the downloaded firmware; comparing the extracted version information with the read version information; and if the extracted version information is higher than the read version information, determining that the firmware currently used by the external equipment corresponding to the downloaded firmware needs to be upgraded.
For example, if the name of the firmware corresponding to a certain downloaded camera is found to be CAM0_ v2.3.8.mrg, the version information of the firmware can be extracted from the firmware by the video network terminal to be 2.3.8; the terminal of the video network can also read version information of the firmware currently used by the camera through an IO (Input/Output) command, for example, 2.3.7; the terminal of the video network compares the extracted version information 2.3.8 with the read version information 2.3.7, and it can be known that the version information 2.3.8 is higher than the version information 2.3.7, so that it can be determined that the firmware currently used by the camera needs to be upgraded, that is, upgraded to the 2.3.8 version.
If the name of the firmware corresponding to a certain downloaded HDMI device is found to be CAM1_ V2.3.7.mrg, the video network terminal can extract the version information of the firmware from the firmware to be 2.3.7; the video network terminal can also read the version information of the firmware currently used by the HDMI device through an IO command, such as 2.3.6; the video network terminal compares the extracted version information 2.3.7 with the read version information 2.3.6, and it can be known that the version information 2.3.7 is higher than the version information 2.3.6, so that it can be determined that the firmware currently used by the HDMI device needs to be upgraded, that is, upgraded to the 2.3.7 version.
And if the video network terminal determines that the firmware currently used by a certain external device needs to be upgraded, storing the downloaded firmware corresponding to the external device stored in the preset directory under an upgrade path corresponding to the external device, and creating a configuration file corresponding to the downloaded firmware under the upgrade path. The configuration file is used to record the name of the downloaded firmware, that is, the name of the downloaded firmware is written into the created configuration file.
In a preferred embodiment, before saving the downloaded firmware to the upgrade path corresponding to the external device in step 503, the method may further include: and the video network terminal starts an interface of the external equipment of which the currently used firmware needs to be upgraded and converts the running path corresponding to the external equipment into the upgrading path corresponding to the external equipment. The method comprises the steps that firstly, an interface of the external equipment can be started to store downloaded firmware and configuration files corresponding to the external equipment into an upgrading path, and the external equipment enters a running path corresponding to the external equipment after the interface is started by default, wherein the running path represents a path corresponding to the external equipment in a running state; then, since the file related to the firmware upgrade needs to be saved, the operating path corresponding to the external device may be converted into an upgrade path corresponding to the external device, where the upgrade path represents a path corresponding to the external device in the firmware upgrade state, and the upgrade path may be an absolute path in a USB flash disk (english name "USB flash disk") format.
After the path is switched, the video network terminal can store the currently used external equipment of which the firmware needs to be upgraded, the corresponding downloaded firmware to the upgrading path corresponding to the external equipment, and create the configuration file corresponding to the downloaded firmware in the upgrading path. After the downloaded firmware is saved and the configuration file is created, the file required by the subsequent firmware upgrade is saved under the upgrade path corresponding to the external device, and the video network terminal can close the interface of the external device.
For example, according to the above example, when the video networking terminal determines that the firmware currently used by the camera needs to be upgraded, the video networking terminal opens the interface of the camera, defaults to enter the operation path/dev/video 0 corresponding to the camera, and the video networking terminal converts the operation path/dev/video 0 corresponding to the camera into the upgrade path/mnt/sda/sda 0 corresponding to the camera. The terminal of the converted rear view network saves the downloaded firmware CAM0_ V2.3.8.mrg corresponding to the camera to the upgrade path/mnt/sda/sda 0, creates a configuration file with the name of filename0.txt corresponding to the firmware CAM0_ V2.3.8.mrg under the upgrade path/mnt/sda/sda 0, and writes the firmware name CAM0_ V2.3.8.mrg into the file of filename 0.txt. Therefore, the upgrade path/mnt/sda/sda 0 corresponding to the camera includes a firmware with a name CAM0_ v2.3.8.mrg and a configuration file with a name filename0.txt, where the configuration file with the name filename0.txt records the firmware name CAM0_ v2.3.8.mrg, so as to satisfy the condition required for firmware upgrade. And then the video network terminal can close the interface of the camera.
And if the video networking terminal further determines that the firmware currently used by the HDMI device needs to be upgraded, the video networking terminal starts an interface of the HDMI device, the operating path/dev/video 1 corresponding to the HDMI device is entered by default, and the video networking terminal is converted into the upgrading path/mnt/sda/sda 1 corresponding to the HDMI device from the operating path/dev/video 1 corresponding to the HDMI device. The conversion rear view networking terminal saves the downloaded firmware CAM1_ V2.3.7.mrg corresponding to the HDMI device to the upgrade path/mnt/sda/sda 1, creates a configuration file with the name of filename1.txt corresponding to the firmware CAM1_ V2.3.7.mrg under the upgrade path/mnt/sda/sda 1, and writes the firmware name CAM1_ V2.3.7.mrg into the filename1.txt file. Therefore, the HDMI device includes a firmware with a name CAM1_ v2.3.7.mrg and a configuration file with a name filename1.txt under the upgrade path/mnt/sda/sda 1 corresponding to the HDMI device, and the configuration file with the filename CAM1_ v2.3.7.mrg records the firmware name CAM1_ v2.3.7.mrg, so as to satisfy the condition required for firmware upgrade. The video network terminal can then close the interface of the HDMI device.
And step 504, after the video network terminal is restarted, upgrading according to the downloaded firmware and the corresponding configuration file stored in the upgrading path.
The terminal of the video network can automatically execute the reboot command after the above steps are executed, and then restart the terminal. The video network terminal can also pop up a prompt box for the user to select whether to restart, and execute a reboot command after the user selects to restart, and restart. The embodiments of the present invention are not limited in this regard.
After the video network terminal is restarted, for the external device needing firmware upgrading, the external device can enter an upgrading path corresponding to the external device, and the firmware of the external device is upgraded according to the downloaded firmware and configuration files corresponding to the external device stored in the upgrading path. In a specific implementation, the firmware to be written in the upgrading process can be determined through the stored configuration file, then the firmware to be written in, namely the stored downloaded firmware, namely the firmware corresponding to the firmware name recorded in the configuration file is obtained, and the downloaded firmware is written in the corresponding external device, so that the upgrading of the firmware is completed.
For example, for an external device such as a camera, after being restarted, the terminal of the video network enters an upgrade path/mnt/sda/sda 0 corresponding to the camera, and the firmware CAM0_ v2.3.8.mrg and the configuration file 0.txt stored in the upgrade path are used to complete upgrading of the firmware corresponding to the camera.
For the external device, HDMI equipment, the video network terminal enters the upgrade path/mnt/sda/sda 1 corresponding to the HDMI equipment after being restarted, and the firmware corresponding to the HDMI equipment can be upgraded by using the firmware CAM1_ v2.3.7.mrg and the configuration file 1.txt stored in the upgrade path.
In the embodiment of the invention, the method is carried out by traversing the directory and dynamically upgrading. Mainly utilizing the principle of firmware upgrading, wherein one condition is that a firmware program file and a corresponding configuration file are simultaneously provided; the problem of multiple configuration is solved by dynamically creating a configuration file; and dynamically acquiring the version information of the currently used firmware and the version information of the downloaded latest firmware in a code form for comparison. The embodiment of the invention can only modify the name of the firmware into a format comprising version information, does not need to record the version information of the firmware by using an independent file, and does not need to store the configuration file corresponding to the firmware in the directory for storing the firmware, so that only the downloaded firmware is stored in the preset directory, whether the firmware is upgraded is judged according to the name of the firmware, the configuration file corresponding to the firmware is created when the downloaded firmware is stored to the upgrading path, and whether the firmware is upgraded is judged and the upgrading process is simpler. Moreover, the defect that the firmware can only be upgraded independently before the video network terminal is solved, the firmware of a plurality of different external devices can be upgraded simultaneously by adopting the latest firmware upgrading program, and the workload of the staff for upgrading is reduced.
