Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
Because the enforcement of common carrier 4A system, directly caused the logical network between office terminal and the network element device to be interrupted, the SNMP(Simple NetworkManagement Protocol that uses between them, Simple Network Management Protocol) agreement can't work.Well-known SNMP is application layer protocol, is the part of TCP/IP protocol suite, and it is normally operated on the User Datagram Protoco (UDP) (UDP); SOCKS 5 agreements are the 5th editions of SOCKS, and it is operated between TCP/IP model application layer and the transport layer, transmit transport layer network packet (TCP/UDP), have the very strong transparency for the agreement of application layer.Analysis-by-synthesis SOCKS 5 and snmp protocol characteristic separately and being associated property can be utilized SOCKS 5 agreements to act as agent and transmit snmp protocol UDP bag.
Fig. 1 is the network topology schematic diagram between office terminal and the network element device, as shown in Figure 1, the management area of the corresponding 4A platform in M zone wherein, internal network in the 4A platform management arranges a station server 200, simultaneously this server 200 has interconnectivity with external network, can realize " indirectly " that by this kind mode office terminal 100 is by the audit checking of 4A platform with to the management maintenance of network element device 300.
Adopt scheme shown in Figure 1, office terminal 100 had both met the requirement of 4A platform safety, can effectively carry out assigning of maintenance command to network element device 300 by snmp protocol simultaneously.The introduction that Fig. 2 is detailed snmp protocol under the assistance of SOCKS5 agreement, finish the transmitting-receiving instruction process, its logic flow is as follows:
1) office terminal is set up and is connected with the TCP of server.
2) office terminal initiates to set up penetration channel after UDP penetrates request through behind the safety verification of server.
3) transmit the SNMP instruction issuing to network element device through server the office terminal.
4) network element device sends to the office terminal through server replying.
In the such scheme, office terminal and server can only create snmp protocol Get/Set order UDP bag forwarding channel by Socks 5 agreements, but the alarm event of network element device can't be monitored by Socks 5 servers at this moment, also can't be managed terminal monitoring.For the problems referred to above, the method and system of the application's monitoring network element device alarm event are proposed.
