Exchange System for mobile communication operator is very important for providing continuous services to customers. However traditional solution is too expensive for choosing in the real environment. In this paper, we suggest cost-effective auto backup monitoring solution, which is robust for system failure. And this suggested solution will also can be adopted to the $4^{th}$ generation of IP core network.

In this dissertation, in the light of the above situations, we intend to use new approach for stable and fast backup system. The approach that we propose network and software infrastructure has three different ways by comparison with existing network backup systems. First of all, we use a socket communication so that resolve the shortcoming of weakness of securities; second, TBD utility for minimizing target system loads in the way of instant operating; and third, time division and bandwidth division backup method considered transfer data size(byte) might be useful more stable and fast comparing with FTP Transfer.

In this paper, we propose protective coordination and automatic setting method using agents for distribution system with loop. The proposed protection scheme adopts an agent technology assuming communication among protection agents and auto-switch agents. Having exchanged fault-related information with each other, protection agents and auto-switch agents perform the primary and backup protection and fault section isolation, respectively. this proposed scheme using agents for distribution system with loop is implemented by matlab. Because of the various configuration of distribution system, It's difficult to find cooperative agents for each agent. This paper develops a program to automatically set the cooperative route for the agents.
