Data Center Network Monitoring with TAPs
by Mitch Howards 29 Jun '15

29 Jun '15

Hello All, Was wondering what folks are using to monitor traffic on their networks. Looking into Ixia and APCON devices for dedup and other filtering features as well as passive fiber TAPs to capture the traffic. How are folks handling TAP'ing large data center networks? TAPs at the "distribution layer" would be the best fit for my network but that would require a ton of passive fiber TAPs for the incoming fibers to the distribution switches. The end goal is to not only capture the north-south traffic on the network but also east-west traffic. It seems more efficient to just use SPANs but there are many limitations using SPANs. Thanks in advance for any suggestions. Mitch

Hello there, Does anybody recommend a CDN to work beside GGC and AKAMAI? and if you have a real life deployment, do you have any figures about how much this recommended CDN save from the Internet BW? (currently both of GGC and AKAMAI saves about 40% of our Internet BW) Thanks, Ramy

The university that fired me for being too old some years ago had three Token Rings--one of them Thicknet. And scads and wads of IPX-speaking machines. That HAS been 10 years ago, so maybe..... -- sed quis custodiet ipsos custodes? (Juvenal)

I didn't realise that there was a relevant picture in the museum set -- http://museumofcommunications.org/wp-content/uploads/2012/06/DSC_7116-1024x… shows severak of those cards on shelves, and in the near fore-ground is the bins used for sorting cards for further investigation (one of the "investigation" steps was to take a deck of cards for a similar failure and hold the deck up to the light to see if a single piece of equipment had been involved in every failure (hole goes through the deck). > > -- sed quis custodiet ipsos custodes?
