Two great guys Narendra Popat and Anil Singhal started together in 1984 and have grown their company into a world leader in the Unified Service Delivery Management arena.
Anil and Narendra are both not only technologists, technology leaders but leaders in their community and educations community.
Their specialty is simply great diagnostic and monitoring systems and the highest customer care philosophy. They have proven successful products, technology solutions with a very long and large customer following.
I was fortunate to meet and work with these two gentlemen back in the early 1990’s when their company was Frontier Development and they had developed the highest quality RMON technology and I was trying to get them as a technology partner with Network General. Ironically, they now own Network General and have taken the technology way beyond what we had ever dreamed possible.
In the late 1990’s they changed their name to NetScout Systems and with the introduction of a ground breaking nGenius technology series which today includes the versatile and powerful Adaptive Session Intelligence technology.
The internet is a great tool but before the internet there was the Public Library. The older generation had to go to the Public Library to do report’s and research. We were not afforded the ease of use of the internet. Which brings me to the point, how in the world did we find what we needed with all the books all over the place? We had the “Dewey Decimal System”! We were able to find a book anywhere in the largest of libraries.

The new IEEE 802.11ac standard is changing the rules when it comes to WLAN troubleshooting based on packet capture and analysis. No one disagrees that packet-based analysis is the most complete and most accurate when it comes to WLAN troubleshooting, but the software, equipment, and processes required to perform packet-based analysis are being challenged by 802.11ac.
Data rates can now exceed 1Gbps – Can your analysis software keep up?
Access points are already at 3-stream – Is your monitoring system equally capable?
You now have WLANs deployed across the enterprise – How do you deal with problems that are thousands of miles away?
This week +Jay Botelho of +WildPackets will discuss a solution to address these and many other concerns with the migration to 802.11ac.
+Jay Botelho is the Director of Product Management at +WildPackets, a leading network analysis solutions provider for networks of all sizes and topologies. Jay holds an MSEE, and is a network-industry veteran with over 25 years of experience in product management, product marketing, and complex analysis. Today, Jay leads the wireless strategy at +WildPackets, working with Fortune 1000 customers, network equipment providers and wireless LAN consulting professionals and partners.
After my last appearance on LMTV, I was inspired to share some network nightmares.
I have done many WiFi site surveys and troubleshooting jobs in the past 10 years. On the inside, I’ve been crawling around factories, offices and up in ceilings. On the outside, I’ve been on roofs, poles, towers, ladders and driving around.
One thing I expect to see is the unexpected. I’ll jump to the punch line; planning a wireless deployment by only looking at a floor plan or topography map, is doomed to fail.
The planner, installer and support staff, or team needs to constantly be in communication.
The following examples are from real jobs this year that I thought you would benefit from.
While troubleshooting at a warehouse, I noticed the access point was installed above the HVAC unit and a cable tray that was covered in metal about 15 feet in the air. When I asked to the onsite IT person, “Why was that Access Point installed there?”, he answered, “That’s where the contractor mounted it”. OK I’ll bite, then I asked, “Who asked the contractor to mount it there?”. The reply was, “That’s where the planners at corporate told him to install it”. I then asked if the planners have visited this site or asked for his input to validate the implementation and the answer sadly was, “No”. The moral of this story is to involve the onsite staff with the implementation plan to place the access points in the most optimal position. In this day of smartphones, a photo or video could easily be taken by onsite staff and sent to the planners.
When Network Performance Management Systems started out, they largely depended on SNMP and active ping testing to monitor infrastructure uptime and performance. These two data sets allowed them to monitor the up/down status of devices, as well as link usage and errors over time.
This data was great stuff, but it didn’t take long for network problems to outpace this level of visibility.
Before long, when a link would spike with utilization, it wasn’t enough to know that there was a bunch of traffic on a link – we needed to know what that traffic was, and whether it was expected usage or not. To help us, NetFlow entered the scene, which added the “What is that traffic” to the “How Much” in network monitoring.
Active ping tests, SNMP scans, and NetFlow is slick set of data to have, especially when troubleshooting live problems. But today, many application issues have found a way to duck and hide around these visibility methods, evading detection from the tools using them. This creates a situation where the Network Performance Management System may show green lights for network uptime and health, but the application continues to suffer poor performance.
