Network (In)Visibility Leads to IT Blame Game

Original Entry by : Mike Heumann

Significant changes in the structure and use of IT, including such seismic trends as Bring Your Own Device (BYOD), virtualization and cloud computing, have introduced new challenges to IT administrators and staff. Added layers of complexity require new skill sets and knowledge bases as well as tools to effectively run a modern enterprise network. This raises a few questions about how IT teams are coping with the changes.

The World Cup is Upon Us – But Are We Prepared?

Original Entry by : Mike Heumann

It seems as if the Sochi Winter Olympics and March Madness happened just yesterday, but the month of June is here, and with it, one of the most highly anticipated sporting events of any four year period. It could be argued that the FIFA World Cup is the most popular sporting event in the world, and with a soccer powerhouse country like Brazil hosting the tournament this year – across 12 venues – sports fans are getting the eye drops ready so they can watch every moment of the action between June 12 and July 13. ESPN will present all 64 matches across three networks (ESPN, ESPN2 and ABC).

Dynatrace-Endace Partnership Enhances AA-NPM with EndaceProbe

Original Entry by : Mike Heumann

While at Cisco Live today, I was struck by the traffic patterns on the show floor.  Wherever there was a traffic jam, it seemed as though it was caused by a few people walking slower than everyone else, or by a momentary obstruction that halted traffic.  Enterprise networks share many of the same attributes (and problems) that show floors do in that respect.  The part that makes it worse for enterprise networks (vs. show floors) is that there are mission-critical applications that run on top of these networks.  When networks have performance issues (even momentary ones), the impact on these applications can be catastrophic.

Make Sure March Madness Doesn’t Live Up to its Name

Original Entry by : Mike Heumann

Last month, we talked about how to keep the Winter Olympics from clogging up your networks as employees raced to stream live events during the workday.  Well, in the U.S., today and tomorrow are two of the biggest sports streaming days of the year.  Although we’ve already seen some play-in games this week, when Ohio State and Dayton tip-off this afternoon in the NCAA Men’s Basketball Tournament, the annual “madness” repeats itself all over again. This is because this next slate of games will run almost continually over the coming 36 hours, mostly during regular business hours.  And let’s be honest, most of us want to sneak a peek at the scores and witness some of the thrilling upsets that happen every year.

Endace Packets – Laser Surgery for the Data Center!

Original Entry by : Mike Heumann

Medical procedures today are characterized by precision.  Thirty years ago, most cancer surgeries involved general anesthetic, “opening up” the patient, invasive and radical procedures, extended hospital stays for recovery, and in many cases. significant side effects.  Today, a surgeon can make a small incision, insert a laser probe, and “zap” the tumor, in many cases under no more than a local anesthetic.  The benefits are faster recoveries and little to no side effects.

Today marks the launch of Endace Packets, a protocol analyzer for EndaceProbes, which brings the same level of “laser precision” to the Network Operations (NetOps) and Security Operations (SecOps) process.  Many of you are familiar with Wireshark, the open source network analysis tool.  Wireshark has been the de facto standard for packet analysis in the Ethernet world for nearly a decade, and is used extensively by both NetOps and SecOps personnel.  However, the file sizes of traces produced from 10Gb Ethernet (10GbE) networks is a challenge for Wireshark, as anyone who has used Wireshark on such a trace can attest.  Like surgeries of old, you need to “open up” the patient to find the particular data of interest, which slows issue resolution
