Linux based implementation and performance measurements of dual stack mobile IPv6

The very idea of IP Mobility is to allow anyone from outside to call anyone inside the network. So, in such cases Network Address Translation/Firewall traversal is required selectively. | ISSN:2249-5789 Chaman Singh et al, International Journal of Computer Science & Communication Networks,Vol 2(2), 240-255 Linux Based Implementation and Performance Measurements of Dual Stack Mobile IPv6 CHAMAN SINGH1 K.L.BANSAL2 1 2 Assistant Professor Associate Professor chaman83mca@gmail.com kishorilalbansal@yahoo.co.in 1 Department of Computer Application, Govt.

It is observed that current technology cannot provide the proper way of communication. Peoples are used mobile phones, other connected and wireless devices for communication. Whenever they go from one network to other packets are not transfer properly between home agents and mobile nodes so the solution is required for that. If we are calling to someone and if at the same time cross the home network, call ends so for the better network connection and continues flow of messages, problem should be executed. If any mobile node (MN) goes from Internet Protocol Version 4.0 (IPv4) Network to Internet Protocol Version 6.0 (IPv6) Network there is no problem for the communication with its home agent. What when an IPv6 MN goes from IPv6 network to IPv4 network there is problem for communication with home agent. So Network Address Translation is required at the link of IPv4 foreign Network so that there is no delay for the packets that are transmitting between MN and Home Agent (HA). There should be regular and uniform communications. Some firewalls block traffic based on the direction of their flow. They do not allow packets from outside the network to come inside, without any of the internal systems requesting for the same. But the very idea of IP Mobility is to allow anyone from outside to call anyone inside the network. So, in such cases Network Address Translation/Firewall traversal is required selectively.
