A Checklist for Interconnecting Data Centers
Whether interconnecting facilities in support of high-frequency trading, high-performance computing, business continuity, disaster recovery, migration of virtual machines among physical servers or some other demanding application, there are certain networking requirements that tend to be shared among enterprise data-center managers. Optical networking is not a commodity technology space, and data-center managers must investigate at least seven primary areas of technological differentiation in doing their due diligence to deploy the right solution for their given organization’s specific interconnection requirements:
- Latency—Critically important in electronic trading and a growing range of industries, network latency varies substantially from fiber path to fiber path and multiplexing platform to multiplexing platform. Reducing the fiber path by one physical kilometer of fiber translates into five microseconds of one-way latency that is eliminated, and Time Division Multiplexing (TDM) introduces significantly more packet delay than does Wavelength Division Multiplexing (WDM).

Ultra-low Latency for Linking Data Centers
Certain local and storage area network (LAN and SAN) applications have such severe intolerance of packet delay that even deploying the latest and greatest network interface cards, high-capacity core network switches and multi-core servers will not necessarily ensure that required performance characteristics are achieved. Delivering ultra-low latency in connecting data centers demands its own targeted strategy.
How long does it take for a packet of data to make its way from one point in a network to another? That measurement of time is defined as the latency of a path, and it can be influenced by a tremendous range of factors. Data-center managers in the most latency-sensitive markets must steep themselves in an understanding of all of those factors if they are to give their companies optimal competitive advantage.

Speed of Light in Fiber – The First Building Block of a Low-Latency Trading Infrastructure
Speed has always been crucial to successful trading. However, for firms engaged in electronic and algorithmic trading, the speed of the trading infrastructure is almost as important as the trading algorithm itself. Most discussions involving latency optimization revolve around various equipment such as feed handlers or servers that process market data, order management, analytics and risk.
We are going to focus on optimizing the optical transport portion of the trading infrastructure, which deals with the speed of the physical communication connection between geographically separated execution venues and data feeds.
The Challenge of Big Data
One of the many things that excite me about working in the tech sector is collaboration. Working collectively on new ideas and new technologies with people spread across the globe continues to inspire me on a daily basis. While on vacation a few weeks ago, I was able to watch such collaboration in action at a conference held by Om Malik on the topic of big data.
With a global delegate list and many people remotely interacting through social media channels, the Structure Big Data conference explored all aspects of managing today’s enormous data demands. However, there was one particular discussion that caught my attention. Focused on the challenges of moving big data around the world, this particular dialogue dived deep into the hurdles both business and domestic users face when trying to access data when they need it, where they need it.

Network encryption made easy
Why bring encryption to the transport network? To paraphrase bank robber William “Willie” Sutton: “Because that’s where the data is.”
To date, most data center security efforts have focused on physical security and protecting against Internet threats. However, IT departments can no longer ignore data theft through interception. Despite a reputation for being more secure than standard wiring or airwaves, the truth is that fiber cabling is just as vulnerable to technical hacks. Several years ago, three main Deutsche Telekom trunk lines were breached at Frankfurt Airport in Germany. In the United States, an illegal eavesdropping device was discovered hooked into Verizon’s optical network. Other international incidents include optical taps found on police networks in the Netherlands and Germany, and on the networks of pharmaceutical giants in the U.K. and France. Reports on these high-profile fiber intrusions offered few details. For the most part, hacks typically go unreported, and often undetected.
