The Network Management And Performance Optimizing Based On SNMPV3 Protocol

Along with technical development in Internet with scale that make widely available, the network is more and more big, the network equipments is too increasingly complicated, hence the importance of network management is increasingly convex now.For a long period of developing and its actually application, simple network management protocol SNMP has become in data network that according to TCP/ IP commerce network management in fact of standard/There are there edition till now from it, especially the SNMPV3 puts forward to the network management to explains newly from the safe angle.Aim at now increasingly network virus attacking,and the safe hidden trouble , the SNMPV3 puts forward a set of total solutions to manage to the safe characteristic that enhance the network.It is pity that the work of this aspect still not enough.This articles bases on the above background discussing and studying to the concrete technique of SNMPV3 network management .First,a general introduction is made to the concept and system structure of SNMP, main contents contain the cause of the network management, the network management evolves standardly, SNMP system frame, basic composing element in SNMP, the concept of MIB,the SNMP protocol data unit etc. And so far the edition of SNMPV2 edition to the improvement of the previous edition After that, we generally discuuss the SNMPV3 theories system and constitute main factor of it, at the same time putforwording solution to the shortcoming that previous edition don't do enough to network safty. The third, do the concrete discussion to that the attestation involved in system technique and the method that encrypt, detailed discuss symmetry type password DBS in the system and single directions spread the row encrypts the MD5 in the system encrypts the method.On the sufficient understanding to the SNMPV3 protocol,we put forward to act for the need analysis of the system and design the way of thinking to the safe network management.This design accordings to the specification of SNMPV3 completely, is divided into distribute the machine( Dispatcher) mold, news handling sub- system, safe sub-system based on User- Based model, access and control sub- system based on View-Based model and its MIBs realization, agent initialization sub-system etc. and realize all at last.As an application of safe network management agent ,we discuss concept of network performance and its parameters choose, and design a simple network management solution based on WEB. Thought it to withdraw the performance parameter from system that run the manage agent we designed above. From but usefulness and rationalities of the above design in verificationFinally, proceed the sub-footing to this text and to safe network the management proceeded the outlook.
