An Efficient Method for Private Network Management Using IP Address Translation

Constructions of networks with the private IP addresses, i.e., private networks, become very popular. In general, private addresses may overlap each other. When we manage network equipment in private networks by a remote network manager using network management protocols, each private network requires its own network manager because the manager can not be shared by overlapping private networks. This leads to problems of cost and inefficiency. In this paper, we discuss an efficient method for network management of private networks using the concept of IP address translations. In this method, a new mechanism will be proposed, in which, the globally unique address mapping of SNMP data in address translation will be guaranteed. We will also discuss a trial implementation of the proposed method. By evaluation of network management system models, we will show that the proposed method is effective to reduce the cost and space of equipment in case of a large system including many private networks.
