Ipv6 Tunneling Over Ipv4 Infrastructure

IPv4 and IPv6 are incompatible protocols. For this reason, transition to the new protocol cannot be expected to be painless, and will involve significant costs for service providers and customers alike. If we compare the costs of transition with the non-transition mode or using IPv4 with supporting new services, then it can help us identify the best time to start the transition process .Whenever transition begins there will be no single “flag day” on which the all-IPv4 network turns into an IPv6 network.

Touch Screens With Feeling

One of the most sought-after new features on mobile devices is the touch screen. But that name is a misnomer, according to a group of researchers at Northwestern University, in Evanston, Ill., who point out the obviousthat these displays offer minimal ­tactile feedback. But suppose touch screens could touch you back: You could “feel,” say, the edges of the buttons on a virtual keypad or the links on a Web page.
