Now With 20% More Fiber!

The DataCenterDynamics site has an article I really liked, titled The American Clould's Weakest Link. It covers the sobering speech given by Allied Fiber CEO Hunter Newby at the Seattle DataCenterDynamics conference Thursday. Newby said "Moving apps into the cloud is very dangerous if you don't know your physical fiber route". How very true -- I almost think people take the physical connectivity between data centers for granted some times.

$7.2 Billion of the recent U.S. stimulus money was dedicated to developing the country's broadband infrastructure. Allied Fiber has been applying for stimulus funding and dreams of building one large fiber ring around the country.

I've worked with several places and brokers that know where all of the fiber routes are in America -- what a fun resource that would be to have as public domain. I think much more fiber investment is needed in this country and NOT just in the big / tier 1 cities and markets. I think if the U.S. is to stay competitive, on both the business and home side of things, we must have a more robust fiber infrastructure that reaches everyone. Next to cheap land and cheap power, data center site selection places a strong emphasis on the amount of lit and dark fiber available in the area.

Allied Fiber and TMCnet have built a Dark Fiber Community to bring together optical network providers and the suppliers who help them build. I've also worked with NEF and the vast database of buried and lit services they have. They also have a natural extension of that business in findadatacenter.com Another favorite site and set of research reports I would Love to use if I had money burning a hole in my pocket is TeleGeography.....some pretty cool data here.

Old School Optics

Lightwave magazine has an interesting article that covers an Ovum analyst's thoughts on a generational shift in views on fiber optics and networking technologies.
"The analyst says active optical cables, more holistic approaches to 10/40/100G data rates, and a new focus on size and power exemplify the new outlook. Even consumer markets appear within grasp."

WAN Optimization

Something I have always been simultaneously very interested in and confused by is the wide area network. WAN technologies, optimization and accelerators are creeping up in headlines all over the place. With data centers growing in number and consolidation projects pushing data from geographically disperse locations, the WAN is becoming increasingly important to build and operate. This post is really just to aggregate the information I have run across, help myself understand it better, and with any luck, help someone else interested in the topic as well.

Hardware

  • Matisse Networks has some pretty cool products for what they are calling the "first optical burst switch, purpose-built for scaling metro and campus networks from 10 to 640 Gbps." Their equipment and technology allows you to scale the metro area network beyond 10Gbps while reducing the capital expenditures needed to accomplish it. Optical burst switching combines Ethernet and the enormous bandwidth of DWDM . Matisse is touting it as the next step in the evolution of optical network products ( Fixed wavelength --> Reconfigurable DWDM --> Optical Burst). A whitepaper explaining the technology and products can be found here

"There are four Metro Ethernet scenarios that we see developing.

1. Simple L2 aggregation combined with transport. Limited support for legacy interfaces and no support for TDM. Limited traffic management and service awareness.
2. The God box. Support for TDM grooming, L2 switching and perhaps even MPLS routing.
3. Sophisticated L2 switching and L3 routing. Deep packet classification and traffic management. No support for TDM.
4. The stupid network. Buy dirt cheap commodity transport equipment and manage everything at the wavelength level. Backhaul everything to enormous Cisco and Juniper routers and sort it out there."

  • Here are some Cisco implementation stories of their Wide Area Application Services solution

WAN Optimization/Acceleration

  • Mark Weiner over at the Cisco Data Center Networks blog talks briefly about WAN optimization. He mentions a company that saved 3.2TB (Terabits) of WAN traffic and related expenses within a one month period!
  • An interesting lessons learned story comes from Byte and Switch article about Kansas City based 360 Architecture. Theirs is a story of WAN optimizers and consolidation of SAN resources. The article explains their problem, vendor evaluation and eventual 4X improvement in WAN speeds.

Fiber

Finally - the fiber networks themselves are getting attention as well. The attraction of owning your own private fiber network was underscored by Paetec Holding acquiring Mcleod USA for $492 million in stock. Check out the details and article here
