Description

Status polling method and system for network equipment in broadcast television network

Technical Field

The present application relates to the field of network technologies, and in particular, to a method and a system for polling a status of a network device in a broadcast television network.

Background

With the development of network technology and the gradual increase of the number of users accessing, the topology structure of the broadcast television network becomes more and more complex, and the network devices included in the broadcast television network become more and more abundant. As shown in fig. 1, the broadcast television network sequentially comprises three major parts, namely a front-end machine room 101, a branch front-end machine room 102 and a film area 103 from the head end to the tail end; the front-end machine room 101 is often connected to a plurality of sub-front-end machine rooms 102, each sub-front-end machine room 102 is connected to a plurality of sub-areas 103, and a large number of users need to be accessed to the sub-areas 103, so that a complex tree topology structure of the broadcast television network is formed. In addition, the broadcast television network includes a large number of network devices, and only the front-end machine room 101 includes a large number of network devices such as a transmitter, an optical switch, an optical amplifier, and a splitter; and each access user needs to add a network device matched with the user in the broadcast television network.

In order to ensure normal service operation of the broadcast television network, fault detection needs to be performed on each network device in the broadcast television network. In the prior art, fault detection of network equipment in a broadcast television network is generally realized in a polling mode. Specifically, by setting a special network management device, the parameter information of each network device is sequentially read from the head-end network device of the front-end computer room in the broadcast television network, and then whether the network device to which the network device belongs has a fault is judged according to the parameter information until the tail-end network device of the slice area is polled. As shown in fig. 2, in a common broadcast network device, only when a complete device link from the front-end machine room 101 to the end user of the segment 103 is polled, it is necessary to poll network devices such as a transmitter, a splitter, an optical switch, and an optical amplifier in the front-end machine room 101, network devices such as an optical switch to a splitter in the front-end machine room 102, and network devices such as a splitter, an optical receiver, and an optical network unit in the segment 103 in sequence.

In the prior art, each network device in a broadcast television network is detected in a sequential polling manner. However, the topology of the broadcast television network is complex, and includes many network devices, and only one device link includes a large number of network devices, and as can be known from the tree topology of the broadcast television network, the broadcast television network includes a plurality of device links. This results in a reduced polling efficiency of the broadcast television network, which in turn makes the discovery of faulty network devices in the broadcast television network slower.

Detailed Description

The status polling scheme for the network equipment in the broadcast television network solves the problems that the polling efficiency introduced in the background technology is low and the network equipment with running status failure is slow to find.

In order to make the technical solutions in the embodiments of the present application better understood and make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions in the embodiments of the present application are described in further detail below with reference to the accompanying drawings.

Referring to fig. 3, fig. 3 is a schematic flowchart illustrating a first method for polling a status of a network device in a broadcast television network according to an embodiment of the present application, where as shown in fig. 3, the method for polling the status of the network device includes:

s110: and calculating a polling weight value of the network equipment in the broadcast television network according to the stability and the attention of the network equipment.

The polling weight value of the network equipment is negatively related to the stability of the network equipment and positively related to the attention degree of the network equipment, and the attention degree of the network equipment in an abnormal network area in the broadcast television network is higher than the attention degree of the network equipment in a normal network area.

The stability of the network equipment can record the change of the state parameter value in real time for the important state parameters of input, output, service control and the like of each type of equipment through a background program of a network management server, and the change is endured into a database to be used as a judgment basis for the stability of the network equipment. The attention degree of the network equipment can be used as a basis for attention degree measurement according to the front and back positions of each type of equipment in the broadcast television network, the abnormal condition of the network area where the network equipment is located, whether the equipment is in the current viewing state and the attention degree weight of the network equipment set by the receiving operation and maintenance personnel through a background program of the gateway server. For example: the network management server receives the change of the attention of the network area triggered by the operation of an operator, and when the network management server receives an event triggering instruction for checking the network area, the attention of the network area is set to be the highest so as to reasonably schedule system resources and perform key polling on network equipment with poor stability in the area. By calculating the polling weight values of the network devices according to the stability and attention of the network devices, the importance of different network devices can be quantified.

As shown in fig. 4 specifically, in step S110, according to the stability and the attention of the network device, a polling weight value of the network device in the broadcast television network is calculated, which specifically includes the following steps:

s111: calculating a difference value between a state parameter value of the network equipment and a preset risk threshold value, and calculating a stability weight value of the network equipment according to the difference value between the state parameter value and the preset risk threshold value, wherein the state parameter value reflects the running state of the network equipment.

S112: determining an attention weight value of the network equipment according to the front and back positions of the network equipment in the broadcast television network and the abnormal condition of the network area where the network equipment is located, wherein the more the position of the network equipment in the broadcast television network is, the higher the attention weight value of the network equipment is, the higher the abnormal degree of the abnormal network area where the network equipment is located is, and the higher the attention weight value of the network equipment is.

In general, the closer to the network equipment at the front end of the broadcast television network, the higher the attention, the wider the influence surface; conversely, the lower the attention of network devices closer to the back end of the broadcast television network, the smaller the impact area. For example: the network equipment of the front-end machine room in the broadcast television network has a wide influence range, and all area signals are influenced once a problem occurs. It is important to ensure the processing efficiency of the failure, so the attention weight of the network device of the front-end owner is the highest.

S113: and superposing the stability weight value and the attention weight value of the network equipment by using a weight weighting method, and calculating to obtain a polling weight value of the network equipment.

The stability weight value and the attention weight value of each network device are calculated, and the weight weighting method is used for superposing each subentry weight value, so that the polling weight value of the network device is obtained, the importance degree of the device can be more reasonably considered from multiple aspects such as the stability and the attention of the device, and reference and basis can be provided for polling the network devices with different weight values according to corresponding frequencies.

S120: and determining the network management type of each network device according to the polling weight value of the network device.

Firstly, the network management types can be divided according to the polling weight values of the network equipment. If the network equipment is divided into a normal type and an alarm type according to the stability degree of the network equipment; the network devices are classified into a hosted device type and a VIP device type according to the degree of interest of the network devices. Different network management types correspond to different polling weight ranges, so that the network management types of each network device are correspondingly set. Wherein, the managed equipment is generally old equipment and has low attention; the VIP equipment is core equipment and has higher attention. The running state of the network equipment in the normal type is normal, and under the normal condition, frequent attention of operation and maintenance personnel is not needed, so that the attention degree is low; the network device in the alarm type is a network device with poor stability, real-time attention is needed, the attention degree is high, and fault processing is needed for the fault network device in the alarm type.

Wherein, different network management types correspond to different polling weight ranges. For example: the stability weight value of the network equipment is mainly considered, the attention weight value of the network equipment is secondarily considered, the normal polling weight range is set to be 1-6 minutes, and the alarm polling weight range is set to be 7-9 minutes; considering the attention weight value of the network device mainly and the stability weight value of the network device secondarily, the polling weight range of the hosting device type can be set to be 1-6 points, and the polling weight range of the VIP device type can be set to be 10-12 points.

After the network management types of the network equipment are divided, the network management type where the network equipment is located is determined according to the polling weight value of the network equipment, namely the stability weight value and the attention weight value of the network equipment, so that the network equipment with the same polling weight range is added into the same polling queue. Because the network devices corresponding to the same network management type have the same weight value range, the network management type of the network device corresponds to the importance degree of the device, namely the attention degree and the stability of the device, so that the network devices in different network management types have essential differences in importance.

S130: and respectively adding each network device with the same network management type to the corresponding polling queue, wherein the network management types correspond to the polling queues one to one.

Each network device with the same network management type is added into the same polling queue, namely, the polling weight ranges of the network devices of different polling queues are different, so that when the network devices are polled according to the polling queues, the polling weight ranges can be combined with a polling strategy to poll the network devices.

S140: and starting the polling threads corresponding to the polling queues in parallel, and performing state polling on the network equipment contained in each polling queue according to different polling frequencies to detect the fault network equipment with running state faults, wherein the larger the weight value range of the network management type corresponding to the polling queue is, the higher the polling frequency of the polling queue is.

By starting the polling threads corresponding to the polling queues in parallel and performing state polling on the network equipment contained in each polling queue according to different polling frequencies, the polling frequency of the network equipment can be associated with the polling weight range where the network equipment is located, and then the high-frequency polling can be performed on the network equipment with poor stability and high attention, so that the network equipment with faults can be searched out in a focused and rapid manner.

In addition, the polling weight values of the network devices in the polling queue are all set according to the device importance and the attention, although the network devices in the polling queue are in the same weight value range, the polling weight values are different in size, and the polling sequence may be different during polling. In order to solve the above problem, fig. 5 shows a flowchart of a polling sequence setting method of a network device, as shown in fig. 5, step S140: the method for respectively polling the network equipment contained in each polling queue according to different polling frequencies comprises the following steps:

s141: and sequentially polling each network device in the polling queue according to the sequence of the polling weight values of the network devices in the polling queue from large to small.

By sequentially polling the network devices according to the sequence of the polling weight values of the network devices in the polling queue from large to small, the network devices with poor stability or high attention can be polled firstly. Because the network equipment is poorer in stability and higher in attention degree, and the influence of the network equipment on the broadcast television network is larger, the network equipment is polled firstly, and the fault of the network equipment can be detected and eliminated quickly, so that the normal operation of the broadcast television network is guaranteed.

S142: judging whether two or more network devices with the same polling weight values exist in the polling queue; when the polling queue has two or more network devices with the same polling weight value, step S143 is executed; when the polling queue does not have two or more network devices with the same polling weight value, the process returns to step S141 or ends.

S143: and sequentially polling the network equipment according to the front-to-back position sequence of the network equipment in the broadcast network.

In general, the closer to the network equipment at the front end of the broadcast television network, the higher the attention, the wider the influence surface; conversely, the lower the attention of network devices closer to the back end of the broadcast television network, the smaller the impact area. For example: since the area of influence is wider at the front end, the area signal is affected entirely when a problem occurs. It is important to ensure the processing efficiency of the failure, and therefore, the attention of the network device of the front end machine room in the broadcast television network is usually weighted most. The network equipment is sequentially polled according to the position sequence from front to back, so that the fault of the front-end network equipment can be quickly detected and repaired according to the importance of the network equipment to the broadcast network, and the broadcast network can keep normal operation as far as possible. When there are no two or more network devices with the same polling weight value, the polling can be performed in the order of the original polling weight values from large to small.

According to the state polling method for the network equipment in the broadcast television network, the polling weight value of the network equipment is calculated according to the stability and attention degree of the network equipment, the network management type of each network equipment is determined according to the polling weight value of the network equipment, so that each network equipment with the same network management type is added into the corresponding polling queue, and when the polling thread corresponding to each polling queue is started, the state polling can be respectively carried out on the network equipment contained in each polling queue according to different polling frequencies. The polling frequency of the polling queue is higher if the polling weight range of the polling queue corresponding to the network management type is larger. Through the process, the technical scheme of the application calculates the polling weight value of the network equipment according to the stability and attention of the network equipment, and further realizes the association of the polling frequency and the equipment stability and attention through the association of the network management type of the network equipment and the polling queue, so that the network equipment with a larger polling weight value, namely the network equipment with poorer stability and higher attention can be polled quickly, and the network equipment with running state faults can be searched quickly and accurately. And each network device with the same network management type is added into the corresponding polling queue, so that the polling weight value of the network device is associated with the polling frequency, and the purpose of adjusting the polling speed of the network devices with different stability and attention is achieved. Compared with an undifferentiated sequential polling scheme in the background art, the method can improve the polling efficiency, and further detect the failed network device emphatically and quickly.

When the network equipment in the broadcast television network is subjected to state polling, the polling weight value of the network equipment in a normal type is increased due to the fact that the network equipment possibly has abnormal state parameters, and at the moment, the equipment needs to be focused, the attention of the network equipment is improved, and therefore the polling efficiency is improved; the network device in the alarm type may cause the data of the state parameter to be normal due to the fault repair and the like, and at this time, the attention of the network device may be reduced, thereby improving the polling efficiency. Therefore, as an alternative embodiment, as shown in fig. 6, the network device polling method provided in the embodiment shown in fig. 3 further includes the following steps:

s210: and adding each network device of the normal type into the polling queue corresponding to the normal type.

S220: and when the network equipment corresponding to the normal type is polled, judging whether the state parameters of the network equipment are abnormal or not.

S230: if the state parameters of the network equipment are abnormal, the network equipment is marked as an alarm type, the polling weight value of the network equipment is increased, and then the network equipment with the increased polling weight value is distributed to a polling queue corresponding to the alarm type. Or,

s240: and adding each network device of the alarm type into a polling queue corresponding to the alarm type.

S250: and when the network equipment corresponding to the polling alarm type is used, judging whether the state parameters of the network equipment are normal or not.

S260: if the state parameters of the network equipment are normal, the network equipment is marked as a normal type, the polling weight value of the network equipment is reduced, and then the network equipment with the reduced polling weight value is distributed to a polling queue corresponding to the normal type. And the polling frequency of the polling queue corresponding to the alarm type is higher than that of the polling queue corresponding to the normal type.

Whether the state parameter of the network device is abnormal or not can be obtained by calculating a difference value between the state parameter value of the network device and a preset risk threshold value, for example, when the difference value is less than or equal to 0, it is determined that the network device has a fault and is a faulty network device; when the difference value is greater than 0 and smaller than a preset first threshold value, judging that the state parameter of the network equipment is abnormal, and adding the network equipment to a polling queue corresponding to the alarm type; when the difference is greater than or equal to the preset first threshold and smaller than the preset second threshold, the state parameter of the network device is determined to be normal, and at this time, the network device may be added to the polling queue corresponding to the normal type.

Specifically, after determining the network management type of each network device according to the polling weight value of the network device, the method further includes the following steps:

network equipment corresponding to the normal type and the managed equipment type is arranged into a polling queue A, network equipment corresponding to the alarm type is arranged into a polling queue B, and network equipment corresponding to the VIP equipment type is arranged into a polling queue C;

starting a thread corresponding to the polling queue A, and polling network equipment corresponding to the normal equipment and the managed equipment according to the polling frequency corresponding to the polling queue A;

starting a thread corresponding to the polling queue B, and polling network equipment corresponding to the alarm type according to the polling frequency corresponding to the polling queue B;

starting a thread corresponding to the polling queue C, and polling network equipment corresponding to the VIP equipment type according to the polling frequency corresponding to the polling queue C;

if the service parameter of the network equipment corresponding to the normal type is abnormal, the network equipment is marked as an alarm type, and the weight value of the network equipment is reset; returning to the step of executing the step of arranging the network equipment corresponding to the alarm type into the polling queue B;

if the service parameter of the network equipment corresponding to the alarm type is normal, the network equipment is marked as a normal type, and the weight value of the network equipment is reset.

When the network device corresponding to the normal type is abnormal in service parameter, the network device needs to pay attention to the network device, the polling frequency of the network device is increased, the weight value of the network device is reset, the network device is distributed to the polling queue corresponding to the alarm type, and the network device is monitored in a focused mode.

When the service parameters of the network equipment corresponding to the alarm type are normal, the network equipment does not need to pay attention, so that the polling weight value of the network equipment is reset and is distributed to the polling queue corresponding to the normal type, the polling frequency of the network equipment is reduced, and hardware resources are saved.

The status polling method for network devices in the foregoing embodiment is not only applicable to polling a broadcast television network entirely, but also capable of detecting a network device with a fault by mainly polling a network area related to a user when it is found that a network of a part of users in the broadcast television network has an operation status fault, specifically, as shown in fig. 7, the status polling method for network devices provided in this embodiment includes, in addition to the steps shown in fig. 3:

s310: and determining a network area where a fault network device with operation state faults exists in the broadcast television network as an abnormal network area.

The network management server side can obtain an abnormal network area through receiving fault analysis reported by a user, or judge whether a connected network, a region, a parcel or a machine room normally judges the abnormal network area. The abnormal network region can include device links associated with only abnormal users. As from the front end of the broadcast network to user a, there is in turn a main link L1 and an end link L2, while from the front end of the broadcast network to user B there is a main link L1 and an end link L3, where user a and user B share an L1 link. If only the user a has abnormal service, it can be determined that no fault network device exists in the links L1 and L3, and a fault network device exists in the link L2, and at this time, the L2 link can be specially polled, thereby saving polling time and improving polling efficiency.

S320: increasing the attention weight value of each network device in the abnormal network area so as to increase the polling weight value of each network device in the abnormal network area;

by increasing the attention weighted value of each network device in the abnormal network area to increase the polling weighted value of each network device, the level of the polling frequency in the abnormal network area can be improved, and the fault network device with the running state fault can be quickly searched.

S330: and adding each network device in the abnormal network area into a polling queue corresponding to the alarm type, and performing state polling on each network device in the abnormal network area according to the polling frequency of the polling queue corresponding to the alarm type so as to detect the fault network device with the running state fault.

By adding each network device in the abnormal network area to the polling queue corresponding to the alarm type, the state polling is carried out on the network devices according to the polling frequency of the polling queue corresponding to the alarm type, the network devices can be polled at a higher polling frequency, and the fault network devices with running state faults can be discovered in time. And for the devices in other network areas, polling can be carried out or not according to the polling frequency of the polling queue corresponding to the normal type, so that the hardware resource is saved.

Preferably, as shown in fig. 8 and fig. 9, the status polling method for network devices provided in this embodiment further includes the following steps in addition to the steps shown in fig. 3:

s410: and calculating the availability of each network device according to the average fault interval time and the average fault repair time of each network device in the device link in the abnormal network area.

The Mean Time Between Failures (MTBF) is the mean time between failures of the network equipment every time and the unit is year; the average fault repairing time is the average time spent on repairing the network equipment, and the unit is hour;

the availability A of the network equipment is opposite to the unavailability U, and A is 1-U;

the unavailability U of the network device is mean time to fail repair MTTR/(24 is 365 is mean time between failures MTBF); according to the calculation formula of the unavailability, in the broadcast television network architecture shown in fig. 9, the availability a and the unavailability U of each network device are as follows:

s420: and building a standby link of the equipment link according to the availability and the front and back positions of each network equipment.

As can be seen from the broadcast television network architecture shown in fig. 9, in the device link, although the network device located at the front end of the device link is more available, the importance and attention of the network device are higher, and once the network device fails, more users will be affected; and the network equipment at the back end of the equipment link has lower availability and lower importance, and users affected by the fault are fewer. And a standby link is built for the front-section part of the equipment link according to the front-back position and the availability of the network equipment, so that the influence caused by the fault of the equipment link can be reduced.

S430: and judging whether the network equipment in the equipment link has abnormal service.

S440: when the network equipment in the equipment link has abnormal service, the equipment link is switched to a standby link to transmit broadcast and television network data. During this time, the device link may be status polled and the failed network device in the device link repaired as per the method in the embodiment shown in fig. 7; and after the fault of the original equipment link is eliminated, switching to the original equipment link to transmit the broadcast television network data.

By setting the standby link, the condition that the network signal is interrupted by the terminal user can be reduced. As shown in fig. 9, once the traffic abnormality occurs in the main channel part (devices 1-6) of the device link, the device can switch to the backup link (devices 7-12), so that there is enough time to poll and locate the failed network device and process the failure under the condition that the signal transmission is still normal.

With reference to the broadcast television network architecture shown in fig. 9 and the availability a and the unavailability U of each network device in the above table, it can be known that:

availability of the device 1 (optical transmitter): a (1) ═ 1-U1 ═ U7 ═ 0.999999999;

unavailability of devices 1-6: u (1-6) ═ 1- (a (1) × a2 × A3 × a4 × a5 × a6) ═ 0.00005001;

unavailability of devices 7-12: u (7-12) ═ 1-a (7-12) ═ 1- (a (1) × A8 × a9 × a10 × a11 × a12) ═ 0.00005001;

availability of devices 1-12: a (1-12) ═ 1-U (1-6) ═ U (7-12) ═ 0.999999997;

availability of devices 13-17: a (13-17) ═ a13 × a14 × a15 × a16 × a17 ═ 0.999913028;

availability of devices 1-17: a (1-17) ═ a (1-12) ═ a (13-17) ═ 0.999913025.

The time of year break of the system (devices 1-17) of the backup link and device link: t (1-17) ═ U (1-17) × 60 × 24 × 365, for about 46 minutes; when the standby link is not built, the annual interruption time T (1-6, 13-17) ═ U (1-6, 13-17) × 60 × 24 × 365 of the original equipment link is about 71 minutes. From the above, after the backup link is built, the annual outage time is shortened by about 25 minutes, thereby reducing the outage of the user receiving the network signal.

In addition, there are a large number of network devices (such as off-network devices) that cannot return status parameters and thus cannot perform polling, and such network devices belong to the managed device. If the device is forcibly polled, network congestion may occur. In order to solve the above problem and reduce network congestion caused by polling the devices, as shown in fig. 10, the status polling method shown in fig. 10 further includes the following steps:

s510: and sending response detection packets to each network device in parallel, wherein the response detection packets are used for enabling each network device to return response data.

S520: it is determined whether response data is received within a predetermined time period, and if no response data is received within the predetermined time period, step S530 is performed.

S530: and determining that the network device which does not return the response data is the managed device.

S540: the status poll to the managed device is cancelled.

The response detection packet may be a simple network management protocol (snmpping packet), the hosting device may be obtained through online heartbeat detection, specifically, the snmpping packet may be periodically sent to each network device through a background thread of the network management server, a thread in the network management server responsible for testing online heartbeat monitors online conditions of all network devices in the entire network all the time, and when it is monitored that a network device that does not respond to the snmpping packet is defined as a hosting device. When a managed device is discovered, the status poll of the managed device needs to be cancelled in order to avoid network congestion caused by forced polling of the managed device. Through online heartbeat detection + stability + attention weight, polling blocking points can be effectively and quickly eliminated, and the efficiency of network operation and maintenance and the flexibility of operation and maintenance are improved.

Through the process of sending the response detection packet in parallel, a network area with poor network performance or a network device with normal network but poor simple network management protocol snmp performance can be detected quickly. In a conventional polling manner, a network management server needs to serially transmit a response detection packet to sequentially poll each network device. The time spent by each polling is the timeout time of one snmp query, the conventional timeout of one snmp query is 6 seconds, the time spent by a network management server polling a blocked machine room with a bad network is about 10 minutes by calculating with 100 devices in a small machine room, and the analysis of the stability weight is directly influenced. The introduction of heartbeat weight can directly exclude such blocking so as to ensure the fluency of the stability weight thread.
