The Network Fault Management In The IPv6 Network

With the booming of the internet technology, traditional IPv4 network has been hardly satisfying people's demands for the massive network applications. The introduction of IPv6 has raised us questions such as the exhausting IP address, but there is no perfect network management system which can be used on management with the new protocol. Thus the paper not only researches the fault which may be occurred and puts on a new method to locate the fault in detail through analyzing the IPv6 MIBs related to the specific fault, but also tries to introduce a new architecture about the fault management in the IPv6 network.The new architecture consists of four modules: alarms module; links module; interfaces module; analysis and separating module; The alarms module proposes an extensible request of alarm-processing in the fault management. The links module and interfaces module introduce the method to locate the fault in detail through analyzing the IPv6 MIBs related to the specific fault. The analysis and separating module analyzes any kind of fault which may be occurred and show the construction of the fault system and how every module works with each other.In the same time, the thesis accomplishes a module of the architecture with Java.It focuses on the research of the implementation for a software system in an IPv6 network. Making use of the security policies of both UNIX operation systems' (such as Linux, Solaris, FreeBSD) and the Java Virtual Machine's, it is sure that the architecture is effective and workable through comparing the accomplished module with current fault management on the cost of network communication.In addition, an IPv6 simulator is introduced to make the network more really.However, the problems requiring further studies are discussed.
