IPv4 depleted

The Number Resource Organization (NRO) announced today that the free pool of available IPv4 addresses is now fully depleted…

“This is an historic day in the history of the Internet, and one we have been anticipating for quite some time,” states Raúl Echeberría, Chairman of the Number Resource Organization (NRO), the official representative of the five RIRs. “The future of the Internet is in IPv6. All Internet stakeholders must now take definitive action to deploy IPv6.”

Jet-Stream’s VDO-X CDN technology is fully IPv6 compliant. How about your CDN?

T-Mobile tests dynamic data access blocking

T-Mobile is testing partial blocking of data access to smart phones during peak traffic.

Source: AD (Google Translate)

T-Mobile (an exclusive iPhone carrier similar to AT&T) suffered from network outages in crowded areas due to video usage on smart phones. T-Mobile wants to block access to popular services like YouTube during peak hours to guarantee that users at least can still call and send text messages.

T-Mobile doubled their network capacity, but network traffic increased faster. FYI the data load of T-Mobile’s network overhere is just approx 1-2Gbps, which is really nothing compared to what streaming CDNs can pump out of their 3G / mobile platforms.

IMHO this approach is completely wrong. T-Mobile (and other carriers) have been promoting 3G as ‘the wireless broadband’ for many years. They created great expectations which they cannot live up to. Instead of looking for a sustainable model, T-Mobile looks at their partners (content services providers) and their customers as their enemies they should limit and frustrate.

The only sustainable approach is to look at the entire costs and revenue structure. Costs have to go down: logistical offloading. Revenues have to go up: bigger, more flexible broadband plans and even more importantly: content delivery revenue streams.
