Mobile Agent-Based Network Management

IP is the primary protocol that establishes the Internet; it is responsible for routing packets across network. IPv4 is the first version of the protocol to be widely deployed. IPv4 uses 4 bytes addresses, which limits the address space to more than 4 billion possible unique addresses. All of network devices construct on the IPv4. While the Internet widely deployed and used. IP addresses are being incrementally delegated to end users, an IPv4 address shortage has been developing. IPv4 addresses were insufficient for the Internet. IPv6 provide 2128 address and provide sufficient IPs for the Internet. But now the software and devices are only supporting IPv4. In this paper, we developed a new UTM appliance. The proposed system considers the integration of IPv4 network and IPv6 network in the Internet.
