LMTV LIVE | Resilience Within A Security Architecture (with Keith Bromley and Steve McGregory)

LIVE EVENT START TIME : Wednesday, May 30, 2018 - 9:30 AM PST

NetworkVis_Ad_TroubleshootIT_170x200Keith Bromley and Steve McGregory from Keysight Technologies (formerly Ixia) will be talking about a security architecture concept called Network Security Resilience. While this concept is not new, it has received as much attention as typical defensive strategies have. This may change with the new NIST Framework for Improving Critical Infrastructure Cybersecurity that places more effort on breach recovery and mitigation.

Basically, it’s not a question of IF your network will be breached, but WHEN. News broadcasts for the last several years have shown that most enterprise networks will be hacked at some point. In addition, the time it takes for most IT departments to notice the intrusion usually takes months—over six months according to the Ponemon Institute. This gives hackers plenty of time to find what they want and exfiltrate whatever information they want. What if you could reduce that time to 1 month, i.e. cut it to 1/6 of the time? Or maybe reduce it further to one week, or maybe to just one day? What if you could go further? Would that be of interest to you?

LMTV LIVE | Improving Packet Analysis with Synthetic Testing (with Steve Brown and Ward Cobleigh)

LIVE EVENT START TIME : Wednesday, May 16th, 2018 9:30 AM PST

AlterEgoQuiz_LMT200Whether troubleshooting basic user complaints or trying to determine performance in the cloud, the challenges are the same in determining:

  • Where to begin troubleshooting?
  • Is it the network, application, client, server, or now cloud?

We’ll join with experts from Viavi product manager Ward Cobleigh and solutions director Steve Brown to discuss how to use synthetic testing to improve troubleshooting with packet analysis. In this edition of LMTV, we’ll focus on:

  • Extending visibility to the network edge, public cloud, and remote users
  • Confirming issue domain gets to root cause faster

We’ll also run through Viavi’s newest cloud NPM service ObserverLIVE showing troubleshooting examples for the public cloud, distributed architectures, and constant network firefighting scenarios. In the meantime, you can learn about free trials of the service at: www.ObserverLIVE.com


LMTV LIVE | How Tools Must Adapt To NPM Specialists (with Scott Sumner and Boris Rogier)

LIVE Event Start Time: Wednesday, April 25, 2018 - 10:00 AM

We will discuss a number of good technical subjects that relate to troubleshooting tricky scenarios like SaaS applications, SAP and Citrix, and ways that TCP analysis can be used to streamline hybrid-cloud app performance. In particular, we would use this first session under the Accedian brand to discuss more about how we see the future of tools, and what can be done to simplify and accelerate the work of NPM specialists with automation and real-time analysis.

Accedian commits to the future of this space, addressing the emerging challenges that will confront analysts as we move increasingly towards combined legacy /physical and virtual / cloud infrastructure.

Fixing TCP Performance Issues Impacting SaaS and Cloud Applications (by Will Moonen)

In my day-to-day practice as a TCP relationship therapist for cloud services, applications, and networks, more often than not, the not-so healthy beginnings and endings of TCP relationships have a significant impact on the user experience. When TCP doesn’t work efficiently, SaaS and cloud application performance rapidly degrades  – this class of applications, in particular, are highly dependent on consistent, efficient network performance.

So, how can you tell if these critical relationships are healthy? And if not, where do you start fixing things? To what extent is the integrity of your data impacted?

Especially in today’s end-to-end encrypted, turbo-charged, hybrid environments, it’s many times like looking for a needle in a haystack!

There is hope. After hundreds of troubleshooting sessions with the dozens of enterprises I work with, I’ve found that there is a well defined process that helps you isolate SaaS and Cloud application performance issues using TCP analysis. This means looking into the details of each session, to determine where to start.

The way TCP sessions set up and tear down directly impacts SaaS and Cloud performance, and the user experience, especially if there are reasons to believe that hosts are overloaded and messages are dropped. A persistent increase in the number of TCP zero window (0-Win) events and duplicate acknowledgements (DupAck) are typically good indicators that end-users are suffering from degraded performance.

LMTV LIVE | How to Improve Network Performance (with Keith Bromley and Jim Sullivan)

Keith Bromley from Keysight Technologies (formerly Ixia) and Jim Sullivan from ExtraHop will be talking about how to use network visibility to improve network performance. In short, network visibility is what enables you to quickly isolate and resolve performance issues; ultimately ensuring the best possible end-user experience.

Since tactical data loses 70% of its value after 30 minutes, the speed and accuracy of data analysis is critical. A proper visibility architecture addresses the strategic end-to-end monitoring goals of the network, whether they are physical, virtual, out-of-band, or inline security visibility.
