IP traffic to 'double' every two years

Web traffic volumes will almost double every two years from 2007 to 2012, driven by video and web 2.0 applications, according to a report from Cisco Systems. Increased use of video and social networking has created what Cisco calls 'visual networking', which is raising traffic volumes at a compound annual growth rate of 46 per cent.

Cisco's Visual Networking Index (PDF) predicts that visual networking will account for 90 per cent of the traffic coursing through the world's IP networks by 2012. The upward trend is not only driven by consumer demand for YouTube clips and IPTV, according to the report, as business use of video conferencing will grow at 35 per cent CAGR over the same period.

This is the reason why we need to move to ipv6

I dont think ipv6 is going to improve this. Sure, it will help, because technically ipv6 was planned to relive the routers from some "processing stress", but apart from that..

I'm pretty sure it will solve the problem for centuries to come. IPv4 supports up to 4.3 billion addresses, whereas with IPv6, you could distribute 50 octillion addresses for every single human on Earth!!!

well, either ipv6 will help or it will not.
And ipv6 should technically help. Which means it will improve this somewhat.

IPV6 has nothing to do with traffic volume, only addressing.

ipv6 has everything to do with it; ipv6 has better management of bandwidth and so forth; I've only had a brief over view of the specs, but it is alot more than just 'more addresses'.

ipv6 is more "hierarchycal" when it comes to addresses in order to simplify the routers' routing tables. It also has a mostly fixed header size (40 bytes, instead of the variable header of 20 bytes + something). It also drops the CRC checksum of the header, so now routers don't have to re-calculate the CRC for every datagram they forward (since forwarding a datagram means decreasing the max-hops, formerly known as TTL, field). These things can result in a more efficient routing and faster.. "processor-wise", but I doubt it's automatically going to be amazingly fast just because of that.

Will multicast get any better with IPv6? It seems that some problems could be solved with it...

IPv6 is better than IPv4 in many ways, but the bottom line and point of this article is that there is more IP traffic going around the internet. IPv6 might reduce some overhead but that is only an extremely tiny fraction of IP traffic today.
