In this paper, we propose a self fault-managed and self reconfigurable peer-to-peer architecture for increasing the availability of the network management system (NMS). We intend to achieve such a goal through increasing fault tolerance property of the NMS by applying redundancy. However the architecture we proposed does not impose any hardware redundancy but software redundancy. This is mainly because we use some peers in several roles and thus add some software redundancy which is easily tolerable by advance processors of NMSpsilas peers. We conduct extensive simulation study to examine the performance of the proposed architecture in presence of nodes' failure. We also investigate effect of failure in different nodes and sensitiveness of the architecture to those failures. The results show that the proposed architecture offers higher availability in comparison to a non-fault tolerant Peer-to-Peer NMS.
