The Web, Statistics and Predicting the Future with Big Data

The web is becoming almost human – we can use the same types of algorithms for web page analysis, medical research and social science. 


Big Data for everyone

by Juniper Employee on ‎09-21-2012 10:42 AM

You may be using big data applications and not know it.


Big Data is being used to proactively find health problems.  Large statistically accurate samples are good for your health.


Knowledge is power.  Big data offers the potential to make more by knowing more.


If “big data” is comprised of your data, do you have rights on its usage?


Here is an application that did not wait for the network to adjust to it.  Is this a new trend?


Planned and unplanned tests of business continuity programs.  Are you ready for the next heat wave?


Are you struggling to manage all the smart phones and tablets invading your campus?  Overwhelmed by the sheer number of requirements for dealing with devices, applications and security?  There is a way to manage all this.  Juniper calls it being “Simply Connected.” And we have products to help you to get there.



At a large industry conference last fall, I had the opportunity to talk to my neighbors about what was new and interesting in their worlds and in their networks.  Interestingly, the answer was some variation of the following: “My boss wants to use his new iPad at work.  We have to change/fix/install new network policies to make this happen.”  When I asked what had to change in order to make this easy, the same three themes emerged:


  • They need a better way to provision tablets.  While they can support the boss as a one-off, they can’t fix everyone’s tablets to make them compatible and secure in the workplace.
  • They need more 802.11n wireless solutions in place—their current coverage is insufficient.
  • They need to figure out what to do if everyone wants tablets and smart devices.

How to Really Read Latency Reports

My very favorite quote on speed and measurement comes from Alice in Wonderland:


"Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run at least twice as fast as that!"

(Through the Looking Glass)

Interestingly, this passage actually relates very nicely to how vendors measure latency in their networking devices.   When we read latency figures, we logically assume that the number represents the length of time it takes for a packet to enter the switch and come out the other side.  True enough, as far as it goes.  But there are lots of ways to measure the speed of a packet as it traverses a switch.  And there are lots of questions that should be asked in order to really understand what was measured and how.  An interesting new white paper that details these questions and provides additional insight into what “latency measurements” really mean can be found here. 


Who is fastest switch in the west?

So why settle for microseconds when you can have nanoseconds?


The more work you can get done in each second, the more productive you are—especially if you are in the financial services or high-performance computing industries.  Switches that deliver transactions in terms of nanoseconds are 10 times more productive than their microsecond counterparts.


If speed in nanoseconds is the goal, how do you find the fastest switch in this category?  There are several dimensions that should be taken into consideration:  latency, jitter, and multicast. 


Latency considerations include packet size and throughput.  How fast can a switch transmit each packet size at wire speed and not drop anything?  To really understand how a switch behaves under stress, you need to test all ports at the same time using 100% unicast traffic throughput in a fully meshed pattern using RFC 2544 and RFC 1242 (for cut through switches).


It is very easy to go fast on the freeway when there are no other cars.  So you need to look at how fast a switch transmits at wire speed through all ports with full traffic load.  Anything less than less than 100% line rate traffic and full mesh to all ports is wimpy.


I’ve pointed out that production data centers have five different variations, and I’ve covered four of them in previous blogs. Today, I’ll talk about the fifth—hosting data centers.


Hosting production data centers come from the classical hosting services market.  These providers started by hosting servers for customers who did not want to maintain their own server farms.  Unlike having your content in a cloud, you know exactly where your content is—it is in the servers that the hosting provider manages for you.
