Shown in upper table, although the network element IP that the source IP of the data returned and webmaster are extracting version information is inconsistent,
But the snmp stack of webmaster is matched according to request-id, will be considered that the reply data for having received these network elements.
Fig. 4 is this specification preferred embodiment network element simulated technological process schematic diagram 1, as shown in figure 4, webmaster is soft in the above process
5000 network elements are configured in part, webmaster is sent to the SNMP messages of network element all by the processing of extensive net element simulation system.It should
Extensive net element simulation system is made of an IP mapping block and a network element simulator.IP mapping blocks are by every 250 IP
It is mapped as an IP.Network element simulator software can start 20 threads at runtime, and per thread has its independent SNMP transmitting-receiving
Module and MIB processing modules, each SNMP transceiver modules bind an IP address.Webmaster is sent to 5000 network elements in this way
SNMP messages will be received by 20 SNMP transceiver modules respectively after IP maps, and be handled by respective snmp stack
Afterwards, it transfers to respective MIB processing modules to handle and response message is sent to webmaster by SNMP transceiver modules again.Namely network element mould
The per thread of quasi- device is responsible for handling the message of 250 network elements, for example webmaster is directed to 192.168.1.1~192.168.1.250
Network element send message can all be handled by thread 1, webmaster be directed to 192.168.2.1~192.168.2.250 network elements message
The message of transmission can all be handled by thread 2, and so on, network element simulator is opened by a process, the very little of 20 threads
Pin provides for 5000 analogue network elements in conjunction with IP mappings, and hardware resource requirements are few, efficient, and the process of data configuration is simple,
Human cost is low.
Embodiment two
Network management system needs to carry out the pressure test of 5000 network element scales, can synchronize the configuration file of 5000 network elements
(network element instructs according to the SNMP of webmaster and uploads files to ftp server by FTP), since the operation is very time-consuming behaviour
Make, therefore webmaster can also periodically send status inquiry command after issuing and uploading file command success, inquiry file upload into
It spends and whether finally uploads successfully.
Fig. 5 is this specification preferred embodiment network element simulator schematic diagram 2, selects internal structure chart as schemed, net shown in 5
First simulator.Each process of the simulator software includes several threads.Per thread have independent SNMP transceiver modules and
Distribution module, each simulator simulate a group NEs.One IP address of each SNMP transceiver modules binding terminal.Network element is simulated
Device can hand to distribution module when receiving special SNMP messages (i.e. file upload command and status inquiry command).Distribution
Module determines to be distributed to existing interim thread or starts a new interim thread then according to the community of message
Message is distributed to this thread again.Each interim thread only handles the identical messages of community.Interim thread is receiving file
When upload command, FTP operations can be carried out according to the FTP relevant parameters that the message carries, upload files to specified FTP service
Device, and during this period, the progress report that ftp file transmits is transmitted by responsive state querying command to webmaster, and in file
Auto-destruct afterwards.
Configure the IP address of network element simulator binding：
20 IP of configurating terminal in the terminal of network element simulator operation：192.168.1.1~192.168.20.1, and
Start webmaster.
Configuration of IP maps on the server of network management system, and by 192.168.1.0/24, this 255 IP are mapped as
192.168.1.1；192.168.2.0/24 this 255 IP are mapped as 192.168.2.1, and so on, 192.168.20.0/24
This 255 IP are mapped as 192.168.20.1, and IP is activated to map.
| IP before mapping | IP after mapping |
| 192.168.1.0/24 | 192.168.1.1 |
| 192.168.2.0/24 | 192.168.2.1 |
| 192.168.3.0/24 | 192.168.3.1 |
| ... | ... |
| 192.168.20.0/24 | 192.168.20.1 |
Increase by 5000 network elements in network management system, IP address is respectively：
| 192.168.1.1 | 192.168.2.1 | ... | 192.168.19.1 | 192.168.20.1 |
| 192.168.1.2 | 192.168.2.2 | ... | 192.168.19.2 | 192.168.20.2 |
| 192.168.1.3 | 192.168.2.3 | ... | 192.168.19.3 | 192.168.20.3 |

These messages can be received by the SNMP transceiver modules of different threads according to the difference of its destination IP and be transferred to point
Resume module is sent out, distribution module is distributed to different interim threads according to the difference of the community of message again.It is each interim
Thread is responsible for primary complete ftp file upload and SNMP status inquiries response, auto-destruct after task.
The message that webmaster receives is as follows：
Shown in upper table, although the source IP of the data returned and webmaster are just inconsistent in the network element IP of synchrodata, net
The snmp stack of pipe is matched according to request-id, will be considered that the reply data for having received these network elements.The same source
The value of the identical OID of IP and different, repeatedly inquires the same OID, value is changed according to actual conditions, i.e.,
This value is stateful.
Fig. 6 is this specification preferred embodiment network element simulated technological process schematic diagram 2, as shown in fig. 6, being configured in webmastering software
5000 network elements, webmaster are sent to the SNMP messages of network element all by the processing of extensive net element simulation system.The extensive network element
Analogue system is made of an IP mapping block and a network element simulator.Every 250 IP are mapped as one by IP mapping blocks
IP.Network element simulator software can start 20 threads at runtime, and per thread has its independent SNMP transceiver module and distribution
Module, each SNMP transceiver modules bind an IP address.The SNMP messages that webmaster is sent to 5000 network elements are mapped by IP
After will be received respectively by 20 SNMP transceiver modules, and hand over distribution module, distribution module is according to the information after parsing
Community information checks for corresponding interim thread, and the information is delivered interim thread if thread exists,
An interim thread is created if thread is not present, then information is delivered.Interim thread is in the letter for receiving distribution module distribution
After breath, action is made according to the particular content of information：It, then will be specific according to the parameter in information if it is FTP uploading instructions
File uploads ftp server；If it is status query instruction, then corresponding state value is returned to according to the progress actually uploaded.Net
The per thread of first simulator be responsible for handle 250 network elements message, such as webmaster for 192.168.1.1~
192.168.1.250 the message that network element is sent can all be handled by thread 1, webmaster for 192.168.2.1~
192.168.2.250 the message that the message of network element is sent can all be handled by thread 2, and so on.Network element simulator passes through one
The expense combination IP mappings of process, the very little of 20 interim threads of thread+30 just easily provide 5000 analogue network elements, and
Each analogue network element is able to carry out the state of the respective FTP operations of FTP operation and maintenances.
