Cornered!
Cornered! is a blog devoted, most of the time anyway, to telecommunications: local and global issues, technology, people and trends from the perspective of someone who's been reporting, analysing and commenting on the industry since the dark ages (BC - before competition). Sometimes serious, sometimes flippant, sometimes frivolous. Controversial, analytical, informative, amusing, but never boring; a vehicle for examinations of important issues and observations on my encounters and experiences in an industry where polarised views and hyperbole are the norm.

Cisco riding high on a flood of terabytes E-mail

Cisco attributes burgeoning sales of its high end carrier router to carriers having to cater for massive increases in video traffic on the Internet, but how do carries generate additional revenues to recoup their investments?

When Cisco launched its flagship core network router product, the CRS-1, in mid 2004 it lobbed onto the market with a massive maximum throughput of 92Tbps. The CEO of Cisco Australia, Ross Fowler said at the time that "I think this has caught the industry by surprise...nobody expected a 92 terabit router...The benchmark today is 940Gbps and they can be daisy-chained to achieve about 10Tbps. This is a major leap forward."

Cisco pointed out that a single fully configured CRS-1 pumping through 92Tbps would be able to support a 850kbps broadband connection to every household in the USA, or handle three billion telephone calls per second.

Cisco hasn't said if it has yet sold a fully configured CRS-1 (very unlikely) but it has just announced total sales of 1800 units, and significantly that half this total was sold in just the last nine months, to the end or March 2008.

It's flagged the driver of this growth as being the increase in video traffic on the web, quoting Michael Howard, principal analyst at Infonetics Research, saying: "Exponential traffic growth on the Internet - driven largely by increased deployment of video services - is causing more and more providers to rethink their core architectures...as business and residential consumers demand more video content in increasingly personalised bundles."

Cisco has available a couple of very comprehensive white papers setting out its methodology and forecasts for traffic growth: Global IP Traffic Forecast and Methodology, 2006–2011 and The Exabyte Era.
