Hotspot 2.0 primer: Another step toward Wi-Fi/cellular integration
This article is part of the December 2011 Vol. 2, No. 6 issue of Network Evolution
When Deutsche Telekom CTO Olivier Baujard took the keynote stage at the Broadband World Forum in September, he proclaimed this to be the prime time for Wi-Fi/cellular integration. His reasoning? Ninety percent of mobile device traffic actually originates from home or work, while only about 10% takes place while users are in transit. So if users are sitting in their offices or a very nearby coffee shop, shouldn't they be able to offload traffic onto optimized Wi-Fi networks? Deutsche Telekom and other carriers seeking congestion relief would like to answer that question with a resounding “yes.” And the same goes for most major enterprises that would like to enable users to walk out of their offices to a local coffee shop and seamlessly roam between cellular and Wi-Fi networks. Yet in most cases, seamless roaming between the two doesn't exist since users have to authenticate every time they log onto a Wi-Fi network. Hotspot 2.0 aims to change all of that. What is Hotspot 2.0? Hotspot 2.0 (HS 2.0) was developed by the Wi-Fi ...

Hotspot 2.0 and the IEEE 802.11u protocol could allow mobile device users to securely roam between Wi-Fi and cellular networks without stopping to authenticate.
Implementing FCoE network convergence is possible considering the move to 10 GbE and the emergence of data center bridging.
FCoE at the edge can be a step toward network convergence, but end-to-end FCoE needs a whole lot more engineering before it can be reliable.
Think VM mobility and follow-the-sun data centers work for high availability and disaster avoidance? Think again. Long-distance migration is still a problem.
