Low-Latency Trading via Fractional/Dim Services

Posted on June 3, 2011 by Brian Quigley

“Fractional,” “dim,” “passive,” “colors,” “lambdas” … there are a lot of names for this flavor of available service for supporting low-latency trading, and there are a lot of reasons why a trading firm or investment bank might choose to take this approach.

In a fractional/dim service, a trading firm or investment bank contracts with a network operator for a specific “color” of light across a fiber-optic network that links locations in a metro application that are strategically important to the customer. The Service Provider essentially places an optical multiplexer on a pair of fibers that has inputs for multiple colors and combines them for transport across a pair of fiber. On the other end, they place a demultiplexer to break out individual client handoffs. Generally, a coarse wavelength division multiplexing (CWDM) multiplexer allows four, eight or 16 colors, and a dense WDM (DWDM) multiplexer allows anywhere from four to 120 colors. Read more →

Are We Entering the Age of WiFi?

Posted on June 2, 2011 by Gareth Spence

There are few reports in the networking industry that illicit as much dialogue and debate as Cisco’s annual Visual Networking Index (VNI). This year’s report proves no different. Released yesterday, the report has already garnered significant media coverage and a brief glance through some of the figures reveals why. There are some incredible predictions here, but one in particular has caught my attention.

Cisco forecasts that by 2015, there will be a significant shift in global IP traffic, with WiFi devices consuming more bandwidth than wired devices. The report highlights that WiFi traffic (including mobile devices) will rise to a commanding 54% of all IP data consumed, while wired traffic will decrease from 63% in 2010 to 46%. This is the first time that such a swing has occurred and there’s no indication that this trend will stop any time soon. Indeed, many analysts believe that wired traffic will only diminish as the proliferation of WiFi-enabled devices continues to grow. Read more →

Could Broadband be the Shining Light of US Infrastructure?

Posted on May 26, 2011 by Gareth Spence

As the political gears in the United States’ electoral machine begin to pick up speed, it’s fascinating to see the topics that are driving discussion. As you would expect, economic growth, employment and social welfare are some of the hot issues being bandied around by potential candidates. Yet one topic that has been largely absent from this early round of dialogue is the state of the country’s transport and communications infrastructure. Looking at some of the latest figures, this may be something that is about to change.

A recent Economist article highlights the critical condition of the country’s heavily overburdened air, rail and road systems. According to research from the World Economic Forum, the country’s infrastructure has actually deteriorated in recent years. In a global 2010 poll, the US was ranked 23rd for its transport systems. With much of the country travelling on antiquated air and rail networks or using roads that have fallen into disrepair, it isn’t surprising to find that this is impacting upon journey times.
