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 networking, in order to solve the technical problems, one of the core technical concepts of the invention is provided, when a monitoring access server receives a monitoring patrol instruction, a monitoring patrol task is started, and the monitoring patrol task is bound with an external control object, so that the external control object controls the monitoring patrol task, and the monitoring patrol task is prevented from being controlled randomly by other threads, thereby ensuring that the monitoring patrol can be carried out normally; the preset sleep time is arranged between every two polling monitoring terminals at intervals, so that the interface can be dormant, the calling performance of the interface is guaranteed, the polling control instruction is not executed in the sleep time, and the problem that the program is crashed due to interface calling failure when the instruction is executed in the sleep period of interface calling is avoided.
Example one
Referring to fig. 5, a diagram of an application environment of a monitoring pricing inquiry control method based on a video network according to an embodiment of the present invention is shown, in fig. 5, the video network includes a monitoring management platform, and a monitoring access server communicatively connected to the monitoring management platform; the monitoring access server is connected with a plurality of monitoring terminals.
The monitoring management platform is also called tangula in the video network, and can be understood as an application system which can be installed on a computer, and the monitoring management platform has the main functions of summarizing all monitoring terminals of the monitoring access server, displaying information of the monitoring terminals, calling monitoring videos of the monitoring terminals and controlling the monitoring terminals.
The monitoring access server may be understood as a server for managing a plurality of monitoring terminals in the internet of view, and in practice, the monitoring access server may acquire monitoring videos of the plurality of monitoring terminals according to an instruction of the monitoring management platform, and may poll monitoring video streams of each monitoring terminal to acquire a current state of the monitoring terminal.
Because the embodiment of the invention is applied to the video network, based on the characteristic that the video network can support the high-definition video conference, the monitoring terminal of the embodiment of the invention can be, but is not limited to, the following equipment: cameras, computers or tablets with cameras, smart phones and the like. When the monitoring terminal is a smart phone, the embodiment of the invention can be applied to a large-scale video conference scene to poll the monitoring video of each smart phone participating in the video conference, and then the host can acquire the participation dynamics of each participant, thereby widening the application range of the embodiment of the invention.
As shown in fig. 6, a flowchart of a monitoring inquiry control method based on a video network according to an embodiment of the present invention is shown, where the method is applied to the monitoring access server, and the monitoring access server may specifically perform the following steps:
in step 601, a monitoring and inspection instruction sent by the monitoring and management platform is received, a monitoring and inspection task is started based on the monitoring and inspection instruction, and the monitoring and inspection task is bound with an external control object.
In this embodiment, the monitoring and inspection instruction may be generated by the monitoring and management platform according to a selection operation of a user on the interface for monitoring and inspection, where the monitoring and inspection instruction is an instruction conforming to a video networking control protocol, and may include a unicast address. The control protocol of the video network can be understood as a protocol used for encapsulating control signaling in the video network protocol; the unicast address is understood to be an interface that uniquely corresponds to a device in the video network, and each device accessing the video network has an interface that can obtain a unicast address that is unique across the entire network. In practice, when the monitoring inspection instruction is transmitted from the monitoring management platform to the monitoring access server, the monitoring management platform and the monitoring access server may be located by using the unicast address.
When the interface corresponding to the unicast address in the monitoring access server receives the monitoring patrol instruction, the monitoring patrol task can be started, wherein the monitoring patrol task can be understood as an operation process of monitoring video streams of a plurality of monitoring terminals which can be accessed in the monitoring access server in sequence. In this embodiment, the monitoring access server may further bind the opened monitoring inspection task with an external control object, where the bound external control object may represent that the monitoring inspection task is specifically controlled by the external control object, and the external control object may be understood as a control thread that may suspend, cancel, interrupt, or resume the monitoring inspection task, and in practice, the external control object may be, but is not limited to, a cancel multithreading object.
By adopting the technical scheme of binding the monitoring inspection task with the external control object, the monitoring inspection task is controlled by the external control object in a targeted manner to pause, cancel, terminate or resume the monitoring inspection, so that the monitoring inspection task is not controlled by other threads at will, and the normal operation of the monitoring inspection is fully ensured.
In step 602, based on the monitoring inspection task, the video streams of the plurality of monitoring terminals are sequentially pulled, and after the video stream of one monitoring terminal is pulled, the video stream of the next monitoring terminal is pulled at a preset sleep time interval.
In this embodiment, the monitoring access server may use the opened monitoring polling task to call an interface for calling a video stream of the monitoring terminal in the monitoring access server, so as to sequentially obtain video streams of all the accessed monitoring terminals, characterize that the monitoring terminal normally works after determining that the video stream of the monitoring terminal is obtained, and characterize that the monitoring terminal does not normally work after determining that the video stream of the monitoring terminal is not obtained. In practice, when the monitoring access server pulls a video stream of one monitoring terminal, the video stream of the next monitoring terminal can be continuously pulled at preset sleep time intervals no matter whether the video stream is pulled. In practice, the video stream may be a monitoring video stream collected by a monitoring terminal, and the sleep time may be understood as a time length for the monitoring server to release a link with the monitoring terminal and sleep after pulling a video stream of the monitoring terminal, where the time length of the sleep time may be set in advance by a user as required.
The technical scheme that the video stream of the next monitoring terminal is pulled at preset sleep time intervals is adopted, and the interface for calling the video stream of the monitoring terminal has the time for releasing the communication link and sleeping of the monitoring terminal after the video stream of the monitoring terminal is called, so that the communication connection with the next monitoring terminal can be successfully established when the interface for calling the video stream of the monitoring terminal calls the video stream of the next monitoring terminal. And due to the preset time of dormancy, the interface is in an initial state when the video stream of one monitoring terminal is pulled, so that the interface has better performance when the video stream of one monitoring terminal is pulled. Therefore, the technical scheme can ensure that the video stream of each monitoring terminal can be successfully patrolled.
In step 603, when an inspection control instruction sent by the monitoring management platform is received, whether the current time is in the sleep time is judged.
In this embodiment, the inspection control instruction may be generated by the monitoring management platform according to a control selection of the user for monitoring inspection, where the control selection may include, but is not limited to, the following: suspending the inspection, terminating the inspection, canceling the inspection and the like. The patrol control instruction is an instruction which comprises a unicast address and conforms to a video networking control protocol.
When receiving the inspection control instruction, the monitoring access server can firstly judge whether the current monitoring inspection task is in the preset dormancy time. If yes, it is indicated that the monitoring inspection task is in the process of releasing the link with the previous monitoring terminal and sleeping, and in this case, step 604 is executed. If not, the monitoring inspection task is not in the process of releasing the link with the last monitoring terminal and sleeping, and in this case, step 605 is executed.
In step 604, after the sleep time, the monitoring inspection task is controlled by the external control object according to the inspection control instruction.
When the task is patrolling and examining in the process of releasing the link with the last monitor terminal and sleeping, if other control operations are carried out at this moment, the interface call can fail, and then the whole process of patrolling and examining is influenced. After the preset sleep time, the interface can be called in establishing a link with the next monitoring terminal and pulling the video stream, and at the moment, the control initiated by the monitoring inspection task can be normally carried out. Specifically, because the external control object is bound with the monitoring inspection task, the monitoring inspection task can be correspondingly controlled by the external control object, so that the monitoring inspection task is in a state aimed at by the inspection control instruction.
If the inspection control instruction is a pause inspection instruction, the monitoring inspection task is paused through an external control object after a preset sleep time of the monitoring access server and the like, namely, the external control object controls the monitoring inspection task to pause according to the pause inspection instruction.
And 605, controlling the monitoring inspection task by the external control object according to the inspection control instruction.
In this embodiment, when the monitoring and inspection task is not in the process of releasing the link with the previous monitoring terminal and sleeping, the interface for calling the video stream of the monitoring terminal is being linked with the monitoring terminal, and the interface is being called, so that the monitoring and inspection task can be controlled. In this case, the monitoring access server may perform corresponding control on the monitoring patrol task through the external control object.
In the embodiment, when receiving the monitoring and inspection instruction, the monitoring access server can start the monitoring and inspection task and bind the monitoring and inspection task with an external control object; when the video streams of the plurality of monitoring terminals are sequentially pulled, the video stream time of every two adjacent monitoring terminals is pulled at intervals of preset sleep time, and when the inspection control instruction is received, if the inspection control instruction is judged to be in the preset sleep time, the inspection control instruction is executed through an external control object after the preset sleep time.
In the embodiment, the monitoring and inspection task is bound with the external control object, so that the monitoring and inspection task cannot be randomly controlled by other threads, and the normal operation of monitoring and inspection is ensured; because the dormancy time is set between every two adjacent monitoring terminals, the called interface has the time for releasing the link and dormancy, thereby ensuring the performance of the interface, further ensuring that the interface can be successfully called when the video stream of one monitoring terminal is pulled, and ensuring the normal monitoring and inspection; because the patrol control instruction is not executed in the sleep time, the problem that the interface in the link release and sleep state is failed to be called to cause the program crash is avoided.
With reference to the foregoing embodiment, in an implementation manner, the external control object further includes an internal control gate, and the monitoring access server may further perform the following steps:
in step s1, the state of the monitoring inspection task is set to a locked state by the internal control gate and a switching signal of the control gate is set to a non-terminated state during the sleep time.
The internal control gate can be understood as a thread which is used for monitoring and monitoring the current state of the routing inspection task in the external control object and can signal the external control object to inform the current state.
In the preset dormancy time, the interface called in the monitoring inspection task is in the state of releasing the link with the monitoring terminal and dormancy, at the moment, the monitoring access server can set the state of the monitoring inspection task into a locking state through an internal control door, after the locking state is set, a switch signal of the internal control door is automatically set into a non-termination state, and the non-termination state can be understood as a signal sent by the internal control door to other threads to represent that the monitoring inspection task is currently in the dormancy period.
In step s2, outside the sleep time, the state of the monitoring inspection task is set to a non-locked state by the internal control gate, and a switching signal of the control gate is set to a termination state.
Outside the preset dormancy time, the interface called in the monitoring inspection task is in the link with the monitoring terminal, at the moment, the monitoring access server can set the state of the monitoring inspection task to be a non-locking state through the internal control door, after the non-locking state is set, the switch signal of the internal control door is automatically set to be a termination state, the termination state can be understood as a signal sent by the internal control door to other threads, and the monitoring inspection task is represented to be not in the dormancy period currently.
Correspondingly, in step 603, the monitoring access server may detect the switch signal of the internal control door, and if the switch signal of the internal control door is in a non-terminated state, it is determined that the monitoring inspection task is in the sleep time.
When the technical scheme is adopted, the monitoring access server can judge whether the monitoring inspection task is in the dormant time or not through the switch signal of the internal control door when receiving the inspection control command, and if the switch signal of the internal control door is in the non-termination state, the monitoring inspection task is determined to be in the dormant time.
According to the embodiment of the invention, the internal control door is arranged in the external control object, so that the monitoring access server can judge whether the monitoring access server is in the dormant time or not according to the switching signal of the internal control door, and the internal control door sets the state of the monitoring inspection task to be in the locking state in the dormant time, so that the monitoring inspection task cannot be controlled by the outside, and the calling performance of the interface and the monitoring inspection performance of the monitoring access server are further ensured.
With reference to the foregoing embodiment, in an implementation manner, the step of performing, by the external control object, control on the monitoring inspection task corresponding to the inspection control instruction may include the following steps:
and if the inspection control instruction is an inspection stopping command, controlling the monitoring inspection task to interrupt the current polling through the external control object.
In practice, the external control object can analyze the inspection stopping command, and then control the interface called by the monitoring inspection task to be disconnected with the current monitoring terminal according to the analyzed result, so that the monitoring inspection task is suspended to run, and then the monitoring inspection is stopped.
And if the monitoring and inspection control instruction is an inspection canceling instruction, the monitoring and inspection task is controlled by the external control object to terminate the current polling, and the binding relationship between the external control object and the monitoring and inspection task is released.
In practice, the external control object can analyze the cancel polling command, and then, according to the analyzed result, on one hand, the external control object controls the interface called by the monitoring polling task to break the link with the current monitoring terminal, and the monitoring polling task is suspended, on the other hand, the monitoring access server removes the binding relation between the external control object and the monitoring polling task, so that the user can manually cancel the monitoring polling task, or the monitoring access server automatically closes the monitoring polling task after removing the binding relation.
In the embodiment, the monitoring access server can perform different controls on the monitoring inspection task through the external control object according to different inspection control instructions, and further removes the binding relationship between the external control object and the monitoring inspection task when the inspection control instruction is the inspection canceling command, so that the monitoring inspection task can be considered to be cancelled or automatically closed. Because different patrol inspection control instructions are provided, different control strategies are provided, and the flexibility of controlling the monitoring patrol inspection is improved.
With reference to the foregoing embodiment, in an implementation manner, the monitoring access server may further perform the following steps:
when polling one monitoring terminal, determining a polling progress according to the number of the polled monitoring terminals and the total number of the monitoring terminals, and generating a first progress report when the polling progress reaches a preset threshold value.
In this embodiment, the monitoring access server may record the polling progress of the monitoring polling task, and specifically, after each video stream of one monitoring terminal is pulled, the percentage between the number of the polled monitoring terminals and the total number of the plurality of monitoring terminals is calculated, and the percentage is determined as the polling progress. And a preset threshold is set, e.g., five percent, a first progress report including the polling progress is generated when the polling progress reaches or exceeds five percent.
And sending the first progress report to the monitoring management platform.
In this embodiment, the first progress report may be a report conforming to an internet of view data protocol, which may be understood as a protocol for encapsulating data in an internet of view. The first progress report may include a multicast address, the multicast address in the video network corresponds to a data stream, and since the data plane of the video network supports point-to-multipoint communication, the data stream may only come from the same data sender but may be sent to multiple data receivers at the same time. That is, in this embodiment, when the first progress report is sent by using the multicast address, the first progress report may be sent to a server, a platform, or a device other than the monitoring management platform. For example, the first progress report may be transmitted to a pamier platform in the video network, where the pamier platform is a platform for performing video conference management in the video network, and when the first progress report may also be sent to the pamier platform, the present embodiment may be applied to polling of a video conference, so as to inform a conference host of a progress of polling a monitoring video of a participant.
By adopting the embodiment, when monitoring and routing inspection, the monitoring access server can determine the polling progress and send the progress report to the monitoring management platform, so that the monitoring management platform can acquire the actual condition of monitoring and routing inspection according to the progress report, and the user experience is optimized.
With reference to the foregoing embodiment, in an implementation manner, the monitoring access server may further perform the following steps:
and when the monitoring inspection task is cancelled at the time preset by the external control object interval, judging whether the external control object is in the dormant time.
In this embodiment, the monitoring access server can regularly cancel the monitoring inspection task through the external control object, specifically, the external control object can be used for canceling the monitoring inspection task at intervals of preset time, wherein the preset time can be set according to the number of the accessed monitoring terminals, for example, the number of the monitoring terminals is 100, and then the preset time can be set to be 2 hours, so that when two hours arrive after the inspection is started, the external control object can cancel the monitoring inspection task, and before the monitoring inspection task, the external control object can first judge whether to be in the dormancy time.
Specifically, the external control target may determine whether or not the internal control gate is in the sleep time based on the opening/closing information of the internal control gate.
And if so, after the dormancy time, canceling the monitoring inspection task through the external control object.
And if not, the monitoring inspection task is cancelled through the external control object.
In this embodiment, when the external control object determines that the monitoring system is in the sleep time, the monitoring and inspection task can be directly cancelled by the external control object after the sleep time. When the system is specifically implemented, the external control object suspends and closes the monitoring inspection task, and the binding relationship between the external control object and the monitoring inspection task can be released.
By adopting the embodiment, the monitoring inspection task can be cancelled at regular time by the external control object, and the binding relation with the monitoring inspection task is automatically cancelled, so that the monitoring inspection task can be cancelled without manual work, and the user experience is optimized; and when the timing is cancelled, if the timing cancellation is just within the sleeping time, the task of the timing cancellation is executed after the sleeping time, so that the service of the timing cancellation is carried out on the premise of not influencing the performance of the interface called by the monitoring inspection task, the performance of the interface is further ensured, and the program crash is avoided.
In combination with the above embodiment, in an implementation manner, before step 603, the monitoring access server may further perform the following steps:
and recording the polling times of all the monitoring terminals which have polled.
In this embodiment, the monitoring access server may record the polling frequency of the current polling complete monitoring terminal in the process of monitoring and polling, for example, if the monitoring and polling task is currently performing round 4 polling, it indicates that it has completed polling all the monitoring terminals for 3 times, and the recorded polling frequency is 3.
Accordingly, after step 604 or step 605, the monitoring access server may further perform the steps of:
and generating a second progress report according to the currently determined polling progress and the recorded polling times.
And sending the second progress report to the monitoring management platform.
The second progress report comprises the current recorded polling progress and the current recorded polling times, wherein the polling progress represents the progress of the current round of monitoring and polling, and the polling times represents the number of rounds of completed monitoring and polling. If the polling progress is twenty percent and the polling times is 3, the monitoring access server is characterized to finish 3 monitoring patrols, and in the currently performed 4 th monitoring patrols, the video stream pulling of the twenty percent monitoring terminal is finished.
The process of sending the second progress report is similar to the process of sending the first progress report, and is not described herein again.
By adopting the embodiment, after the patrol inspection control instruction is executed, the progress report comprising the current recorded polling progress and polling times can be sent to the monitoring management platform, so that the monitoring management platform can know the current patrol inspection result when the monitoring patrol inspection is controlled to be suspended or cancelled, a user can master the patrol inspection efficiency of the monitoring patrol inspection according to the progress report, the dormancy time in the patrol inspection can be adjusted, the optimal monitoring patrol inspection efficiency is achieved, and the user experience is optimized.
