Embodiment
The present invention is further explained below with reference to the drawings and specific embodiments, traditional distributed network management
System is general all containing a total management station and Duo Gezi management stations.Equipment and software regulatory requirement of the invention according to layering
The distribution type network management system of hierarchical structure is established, to the server in antiaircraft firing management system, work station, interchanger, route
The equipment such as device carry out centralized supervisory, and system architecture is as shown in Figure 1.Broadcast polls are exactly supervisory systems by sending SNMP broadcast packets
Mode serially obtain the information of managed devices between the parallel, network segment in the network segment, i.e., often Ge Zi management stations according to being managed
Equipment is divided in different segment by the region of linchpin, is sent a SNMP broadcast packet to each network segment successively and is proposed that data acquisition please
Ask, the reply packet of the sub- parallel receiving device of management station.Because broadcast polls in a network segment only send a packet, phase
The mode of a packet is sent to each equipment to traditional polled, can greatly reduce in network the quantity of polling data bag and
The polling cycle of device polling.
By the equipment and application state that are monitored in network management system are dynamic changes, be likely to occur at any time new registration or
The equipment that person hinders and gone offline for some reason, for all devices and its topology status can be obtained in real time, equipment can be divided by state
For new registration, the online and three types that go offline.When obtaining facility information, some information are metastable, such as factory
Family, device type, configuration information etc., are called static attribute；Some information be it is continually changing, as upstream data flow, under
Row data traffic, lost data packets quantity etc., the referred to as dynamic attribute of equipment.To new registration equipment, it is static that it need to be obtained first
Attribute；To normal online equipment, then need to obtain dynamic attribute in real time, and the acquisition cycle of static attribute can extend.For
The equipment to go offline, if as normal online equipment while poll, bag will cannot be slowly replied, poll thread can then occur
Wait, or even repeat to send polling data bag, cause whole queue poll time long.Therefore, it is not received within a period of time
The equipment that bag is replied to poll specially establishes the device queue that goes offline, by the device polling thread process that goes offline.The equipment that goes offline team
Facility information in row is also the response condition according to equipment and dynamic change.Therefore, algorithm is by distinguishing the state of equipment
Multiple dynamic device lists are established with attribute, by multi-threaded parallel poll with real-time collecting device information.Based on broadcast SNMP
Webmaster parallel polling algorithm before poll starts, initially set up dynamic device list, and in polling procedure, pass through the cycle
Property send SNMP broadcast messages to each network segment and obtain the change of managed devices, dynamic adjusts dynamic device queue；
During poll, by distinguishing equipment state, facility information establishes multiple poll threads and carries out acquisition facility information；Receiving
When, need to receive a large amount of situations for replying packet in a short time for network management system, using the annular based on parallel processing
Cache policy obtains at a high speed data message, matching treatment and reception speed, reduces packet loss when high-speed data receives.
The acquisition of step 1 dynamic device list
To obtain equipment state in real time, current device list RECV (current device shapes are initially set up before poll starts
State table) and global list of devices L (all devices state table).The IP of all devices is preserved in the current network segment in RECV lists
Location and MAC information, and list L is used for IP, the MAC and dynamic state information value for preserving all devices.Poll is then begun to, is passed through
Broadcast obtains the current device information deposit RECV lists of each network segment, and dynamic updates the equipment state in list L.By RECV
Compared with global list of devices L, you can obtain new registration list of devices NEWLIST (latest equipment state table), online equipment
Three dynamic device row of list ONLIST (online equipment state table) and the list of devices OFFLIST that goes offline (go offline device status table)
Table.The dynamic device list and its implication that algorithm is established are as shown in table 1.The acquisition algorithm of dynamic device list is as follows：
1. if the global list of devices L of dynamic is sky, create RECV lists and L lists；
2. network management system sends a broadcast SNMP bag to each network segment successively, obtain and reply equipment in SNMP packets
IP and MAC Address list are simultaneously stored in RECV；
3. dynamic adjusts global list of devices L=L ∪ RECV；
4. by the device IP in the RECV lists got and MAC Address and the device IP in the global list of devices L of dynamic
Compared with MAC Address list, update the state value of each equipment in L, and new registration list of devices is updated according to equipment state
NEWLIST, online equipment list ONLIST and the list of devices OFFLIST that goes offline；
5. empty RECV；
6. turning to next network segment, repeat step 4, each list of devices is dynamically adjusted.
The dynamic device list of table 1 and its implication
Step 2 multi-threaded parallel poll
All devices attribute information is all stored in MIB storehouses, according to the difference of object property in MIB storehouses, can be divided into quiet
State information and multidate information.The static information one of equipment, which is configured, to be kept essentially constant, therefore is not necessarily in each number
According to necessary access all to its poll, is only carried out in gatherer process when static information changes to ensure having for information
Effect, therefore a static information poll thread JT-Thread poll new registration equipment can be established to obtain the quiet of new registration equipment
State information.Multidate information is then as the running situation of equipment constantly changes to reflect the state of equipment or performance in real time.In order to
The change of all online equipment performance parameters is monitored in real time and reflects the running status of equipment in time, it is necessary to managed object
Constantly carry out real-time poll, it is therefore desirable to create the poll thread DT- of all online equipment multidate informations of a poll
Thread.In addition, the renewal of dynamic device list is realized by broadcasting thread BR-Thread.Therefore, this algorithm passes through more
The multiple dynamic device lists of thread parallel poll, gather the static state and Dynamic attribute values of distinct device.The poll line that algorithm is established
Journey, as shown in table 2.
The multithreading list of table 2
| Sequence number | Thread name | Effect |
| 1 | BR-Thread | Broadcast polls network simultaneously updates dynamic device list |
| 2 | JT-Thread | Poll NEWLIST equipment static attribute |
| 3 | DT-Thread | Poll ONLIST equipment dynamic attribute |
Step 3 reception mechanism
When number of devices is more in the network segment, one will necessarily be caused to need to receive in a short time by the way of broadcast
The problem of reply packet a large amount of with processing, therefore, this algorithm is improved to traditional high speed order caching strategy, using one
The adaptive parallel processing cache policy of kind realizes the reception of data, that is, passes through adaptively dynamic adjustment and handle number of threads
Method dynamically adjusts processing speed, to cause processing speed to reach optimum state, improves and data high-speed is received and in time located
Manage the ability of speed.
Fig. 2 show adaptive parallel processing Circular buffer strategy.Due to packet reception rate and processing speed not
Matching, particularly in the case that receiving velocity is far longer than processing speed, can use a receiving thread and multiple processing
Thread parallel is handled to reach the matching received with processing speed.Thread Count N size is handled as poll is carried out periodically
Adaptive adjustment, avoid as far as possible because receive that speed is fast and processing speed slowly caused cache overflow, data-bag lost the problems such as.
The content of the invention of this part is a kind of network management in antiaircraft firing management system, can be achieved to set system
The polling algorithm that standby running status is gathered and monitored in real time, its net involved by primarily directed to antiaircraft firing management system
The features such as network scale is big, distribution is wide, equipment is more, using the parallel polling algorithm based on SNMP, by sending poll in the network segment
Dynamic access equipment real time information is instructed, establishes more poll threads, to solve in legacy network management using the side of poll successively
Formula and the problems such as the existing cycle is long, real-time is low and transmitted data amount is excessive, handled and cached using multithreading self-adaptive parallel
Technology, the mismatch received with processing speed is avoided, improves network management efficiency.
In antiaircraft firing management project, in face of network size is big, distribution is wide, the actual demand more than equipment, legacy network
Management system carries out data acquisition by polling device successively and has that polling cycle is long, real-time is low, lacks more than polling data amount etc.
Point, data acquisition is carried out using the parallel polling algorithm based on SNMP.The algorithm is in poll, by being sent to each network segment
The mode parallel polling managed devices of SNMP packets are broadcasted, reduce the quantity of polling data bag, mitigate the burden of management station,
Shorten polling cycle；When receiving device replys packet, for reception and the unmatched situation of processing speed, using multithreading
The method of self-adaptive parallel processing ring caching, reach the purpose of high-speed data reception.System test result shows, passes through broadcaster
The poll of formula can effectively shorten polling cycle, reduce polling data amount, and be adapted to the reception under high velocity environment to data,
Avoid replying the loss of data, the algorithm can greatly improve the real-time and operating efficiency of catenet network management system.
Parallel polling algorithm based on SNMP can realize the real-time data acquisition of the network equipment, and this method passes through in the network segment
Send broadcast packet and carry out the actual facility information of dynamic access；By distinguishing equipment and facility information, establishing more poll threads, use
Serial manner shortens polling cycle between parallel polling equipment, the network segment in the network segment, reduces the data volume of poll, improves data and connects
The efficiency of receipts, meet that the high-speed data under broadcast conditional receives, improve network management system efficiency.The polling algorithm is highly suitable for
Data acquisition is carried out in the network that equipment amount is big, requirement of real-time is high.
It is located in a cycle T, the size of each packet is a, and a receiving thread, which receives a packet and reached, to be delayed
The average time for depositing area is tr (n), and each average time for handling one packet of thread process is tp (n).Buffer size
For length=a × count, wherein, count is the sum of all devices.
In the case of having a receiving thread and a processing thread in traditional cache policy, as tr (n)=tp (n)
When, the reception speed and processing speed of packet just match, will not occur because of the idle of buffer area or full thread etc.
Treat.As tr (n) ＞ tp (n), the processing speed of packet, which is more than, receives speed, then buffering area has residue.As tr (n) ＜ tp
(n) when, the reception speed of packet is fast and processing speed is slow, can produce because of the situation that buffer area is full and waits.In fact, by
It is related to the sequence of operations such as access of the analyzing and processing to data, database, the processing of a packet in the processing of packet
Time receives the time much larger than it.This algorithm is handled by establishing multiple processing threads, and according to the adjustment of processing speed periodicity
Number of threads is received and the matching of processing speed with realizing.
If system latency time is t (n), processing Thread Count is N, and N=1 is put in algorithm initialization, then t (n) calculating
Formula is：
As t (n)≤0, then a processing thread is only needed；As 0 ＜ t≤tr (n), now tr (n) ＜ tp (n), with
The carry out buffer area of poll can gradually increase, and will influence buffer area handling capacity, therefore it is slow to handle to establish two processing threads
Deposit area's data so that processing thread speed exceedes receiving thread speed；As t (n) ＞ tr (n), then need to be further added by handling line
Number of passes.Processing Thread Count adjustment formula be：
Polling algorithm handles Thread Count by periodically adjust automatically so that the processing speed and receiving velocity of packet
Matching, ensures that the polling efficiency of data acquisition is always at optimum state.
In the network management system of antiaircraft firing management system, the parallel polling algorithm based on broadcast SNMP is used to set in real time
Standby data acquisition.Algorithm initially sets up dynamic device list, and updates these row by broadcast polls thread BR-Thread dynamics
Table.Then, static information poll thread JT-Thread, multidate information poll thread DT-Thread, data receiver thread are created
JS-Thread and data processing threads CL-Thread.After poll starts, each poll thread is from respective queue
NEWLIST, ONLIST obtain information to be polled, and according to broadcast in parallel in the network segment, the mode of serial polling starts extensively between the network segment
Broadcast poll.When receiving device replys packet, the average received time tr (n) of a packet is calculated, is handling the data
Bao Shi, calculate the average handling time tp (n) of a packet.After cycle T, the stand-by period is calculated by formula (1), then
Again by formula (2) adaptively dynamic adjust N size, by main thread create or termination thread, realize processing thread from
Adapt to adjustment.
The detailed process of parallel polling algorithm based on broadcast SNMP is as follows：
