It is very well recognized that intelligence at the end of the network is increasing very quickly. It is less recognized that the networks themselves are becoming much more intelligent.

• Operates at line speed up to 40 Gbs

• Uses GSQL for filtering

• Databases in 100s of Terabytes and trillions of records

• Fully indexed

• Compression 5 or 10 to 1

In order to provide high quality of service across many diverse types of service, the network is becoming much more intelligent

Monitor the quality of compressed video inside the network.

Visual Glitch Detector predicts how viewers will perceive quality of video.

Takes into account human perceptual properties.

Decision about visibility of glitches based on low-level information extracted from each video.

Accurate enough to determine the degree to which specific network impairments affect quality of a specific piece of video content.

Converged global communications networks are both very large, and very Complex. Operating them for high reliability, performance, quality, and security is impossible without high levels of automation and sophisticated, scaleable tools.

Automation

Can the IP Network Run Itself?• How to push automation as far as possible?

• Timely, accurate information is essential!!!

• Tools that separate capabilities from policies, since policies can change fast

• Big Guard Rails – extensive monitoring and info correlation/validation

• Huge Operations involvement at every step

Existing stored information is estimated to be O(10s of Exabytes),with new information each year estimated at O(Exabytes) and growing at 10 – 20% a year. Most of the new information, and much of the existing is, in any year, on a network – i.e. in flight
