Well, it’s that time of year again. The snow is finally off the ground in most of the New England area, opening day of Major League Baseball has come around, but most importantly, it’s Interop time in Las Vegas. This year’s Interop is about a month earlier than Interop of years past, but the activity from the show seems just as high. One of the more interesting announcements I saw from the first couple of days is Gigamon’s Multi Purpose Visibility Fabric Node.

Gigamon, the market leader in traffic visibility, announced the upcoming release of the GigaVUE-HC2 modular fabric node for the Services Layer of the company’s Visibility Fabric. The modularity of the product makes pervasive visibility easier to achieve. Today, visibility requires a number of different components, such as TAPs, packet modification, high-density ports, and intelligent packet modification.

Gigamon’s new GigaVUE-HC2 solves this problem with a modular product that can make it easier to deploy a visibility fabric in a highly complex network environment. The product is a compact 2RU, rack-mountable appliance, so it can be deployed in even the densest environments.

Big data and analytics are hot topics of conversation for almost anyone in IT today, including network operations. This is one of the reasons Gigamon has been on a tear over the past couple of years, especially since its IPO last year.

Last week, Gigamon announced an upcoming application to generate and export NetFlow records from its visibility fabric. The NetFlow Generation application will create NetFlow records and then send that information to one of the many NetFlow collectors and analyzers available on the market today.

Historically, Gigamon has traditionally focused on developing features and applications to help optimize the performance of network tools. This application, though, will help optimize the performance of network infrastructure, such as routers and switches. Generating NetFlow traffic can be very processor-intensive and offloading this to the visibility fabric can reduce the burden on network hardware.

This week, traffic visibility solution provider Gigamon announced its Unified Visibility Fabric, which provides Traffic Intelligence to help enterprises and services providers get a better handle on what traffic is flowing across the network. Gigamon has beefed up the application and services layer of its visibility fabric with new applications and features that offer advanced filter capabilities, such as stateful correction, user-level awareness and deep packet visibility. The Traffic Intelligence provides more granular filtering and forwarding to make sure the tools and applications network managers use to manage and secure the network receive only the data that it needs to operate.

Gigamon’s focus is to provide fabric-wide, integrated applications that send the correct data to the correct tools so organizations can optimize the performance of the tools, including network and application performance.

There’s no question that the trends of video, virtualization, software defined networks, BYOD, 40 Gig and 100 Gig have all added significantly more traffic to networks today. The challenge created from the increased volumes of traffic, combined with increased network speeds, is that the management, performance, and security tools customers use can’t capture the volume of data being pushed to it. Think of network traffic having to pass through a tollbooth and when it gets through, it’s directed to the right tool(s). If there’s too much traffic, then the cars get backed up and the things on the other side of the toll plaza won’t operate as well.

During last week’s VMworld event, traffic visibility leader Gigamon debuted what it is calling “Visibility as a Service,” or VaaS. Network visibility was a big theme at VMworld this year as VMware launched its NSX network virtualization product.

During his keynote, VMware CEO Pat Gelsinger stated that the network is the next IT domain to be impacted by virtualization and, in fact, it’s the limitations of the network that hold organizations back from being able to migrate to a software defined data center (SDDC) or IT-as-a-service.

This sounds great during a keynote, but, practically speaking, virtualizing the network has its risks and complications. I’ve heard many people use the benefits of server virtualization to describe how the network can be transformed and what the impact will be. While I don’t fully agree with this analogy, I do believe that some of the risks are similar. While many companies enjoy the fruits of virtualization today, remember that this technology went through some significant growing pains to get to this point.

All eyes are on Orlando, Florida, this week as Cisco Live gets underway. With all due respect to Interop, the show formerly known as Networkers has become the place to be if you want to learn what’s going on in networking, with over 20,000 in attendances this year. I don’t think anyone would deny the fact that virtualization has become a huge issue for not just server managers but also network managers. In fact, in last year’s ZK Research/Tech Target network purchase intention survey, we asked what technology product was consuming more time and resources compared to the year prior. Server virtualization was the No. 1 response, with over 31% of respondents showing just how big an impact virtualization is having with network managers.

Just a few short years ago, network managers couldn’t have cared less about server virtualization, as it was a technology that was used to improve the utilization of servers and had little impact on the network. Obviously, things have changed significantly over the past few years as the use of virtualization technology has expanded past consolidation.

There’s a Katy Perry Song called “Waking Up in Vegas” in which the young Miss Perry sings “Shut up and put your money where your mouth is / that’s what you get for waking up in Vegas.” That first line, “Shut up and put your money where your mouth is,” should be the theme for Interop. Vendors all across the network market come to Mandalay Bay to show off their latest products and impress buyers, channel partners, media and Wall Street. The following is a list of vendors that I thought did indeed put their money where their mouth is (listed alphabetically):

Arista: Putting your money where your mouth is can be difficult most of the time, but it’s even more difficult when the mouth belongs to the enigmatic Doug Gourlay. For those of you who aren’t familiar with Doug, he’s the marketing equivalent of Terrell Owens. He talks a lot, but normally delivers. Arista and Doug are constantly yapping about performance and the new 7500E Data Center switch certainly didn’t disappoint. This is one monster of a switch with off-the-charts high-speed port density. In a quarter rack, the 7500E has a port density of 1,152 10 Gig-E ports, 288 40 Gig-E ports, or 96 100 Gig-E ports. Remember, these densities are in a quarter rack. The product is also optimized for the virtual data center with VXLAN termination and a bunch of other features.

Most of the focus of software-defined networks (SDNs) has been on how it impacts the layer 2/3 switch vendors. The industry seems to have moved off of this notion that it commoditizes the underlying infrastructure, but recently another question has come up. Big Switch recently launched the company and related products, one of which is called “Big Tap,” that provide traffic visibility functionality similar to what one might get from vendors such as Gigamon and VSS. This has raised a question: are SDNs a death knell to the traffic visibility vendors?

I looked at this and then talked to a number of customers, including Big Switch, and I believe the information that one can get out of an SDN-led product to be very much complementary to the traffic visibility market, not competitive. Think of “Big Tap” as being traffic visibility light where they provide a very basic level of information. The level of information that one gets from the dedicated vendors is much richer and more granular than what one would get from Big Tap.
