The complexity in IP networks is staggering: massive volume, multi-step paths from start to end, and applications and services with strict demands and no tolerance for delay.
These new services add immeasurable complexity to the job of network management while requiring ultra-reliable networks.
AT&T's solution is to drive problems and glitches from the network, and AT&T Research is supplying the innovations to do it.
Year 2 of the Netflix contest began with some believing BellKor was closing on the 10% goal. In a single year, the team achieved 8.43%.

The information comes most alive, often beautifully, when incorporated into visualizations.
Overlaid on maps, the patterns of movement, and the reasons for it, become apparent.
A new book, Guide to Reliable Internet Services and Applications, describes some of the innovative approaches needed to deliver services reliably. The first chapter is available for downloading.
Chuck Kalmanek, one of the book's editors and vice president of network management research at AT&T Labs Research, talks about why the book is needed.
