Protect Your High-Speed Network this Holiday Season

If you’re a retailer that has upgraded to a 10G—or faster—network in anticipation of the holiday season, congratulations are in order because you’ve made a wise decision. Between streaming videos on your website, offering multichannel service in your contact center and running your company’s usual slew of bandwidth-intensive applications, high-speed networks are rapidly becoming a priority for retailers.

But although a faster network will certainly increase your capacity, it also makes monitoring more difficult. After all, a higher rate of data transfer can make it more complex to troubleshoot network issues, and if the network suffers an extended outage or subpar performance, the speed you added speed is essentially useless.

The holiday season can make or break an entire fiscal year for a retailer, so the last thing your company can afford is downtime between now and the New Year. So, to ensure your high-speed system runs smoothly as temperatures get colder and business heats, you need a solution that increases network visibility and ensures optimal high speed network performance.

Best-in-class high-speed network analysis solutions offer end-to-end monitoring and data capture for common applications like Web, Email, IM, and VoIP. Our products ensure that data packets don’t go missing and that your network engineers can quickly view all the relevant information they need to analyze any section of the network. Armed with this data, these engineers can:United States

Data Visibility Challenges at 10G and What You Can Do about It

It’s no secret that networks are becoming faster and much more complex. As network speeds surge to 10G, 40G, and even 100G, it’s impossible to properly troubleshoot network traffic with traditional, “on demand” techniques. Faster-speed networks demand full visibility and 24×7 uptime assurance, which often requires companies to adopt new approaches to network monitoring and analysis.

According to a recent survey by TRAC Research, 41% of respondents say that current network analysis solutions are unable to support 10G networks. As a result, these companies are finding it harder and harder to accurately assess the data traversing their company networks. Our own recent survey found that 43 percent of companies cite limited or no network visibility as the biggest challenge in transitioning to faster speed networks.

So, how do companies meet these challenges head-on, and how do they address the perceived lack of data visibility at 10G+ network speeds? We’ve outlined several ways companies can make the transition while ensuring they’ll have data visibility, and detailed troubleshooting, that’s compatible with today’s high-speed networks.

New Approaches to Network Monitoring and Analysis at 10G
Many companies have attempted to transition to 10G network analysis by simply applying the same technologies that have proven successful in 1G environments. What network engineers and IT directors fail to realize is that 1G monitoring and analysis solutions do not scale adequately to address the high performance of 10G networks, and this often leads to loss of data for analysis at critical moments and delayed inspection time.

New network monitoring and analysis solutions require more powerful platforms, with dedicated interfaces for high-speed data capture. Driven by the massive increase in transactions and data traversing the network, they must be capable of capturing and archiving data in real-time, while also providing real-time feedback on overall network performance, so the data is always available for detailed, packet-based analysis.

Addressing the Data Visibility Challenge
Maintaining network performance in a 10G environment means monitoring more points in the network, and at greater speeds, for more detailed information. Traditional network analysis at 1G collects data through traditional SPAN ports, mirror ports, or taps. Should a problem occur on your network, you simply connect your network analyzer, start a trace, and determine the problem. And if a problem occurred in the past, you either attempt to replicate the problem and solve the issue, or wait for it to happen again.

However, at 10G, it’s a different story. Organizations generate large sets of data on the network at faster speeds, and it’s highly impractical to recreate problems. Instead, organizations must identify key analysis points, install a solution that can monitor the network 24×7, and record all data so that in the event of a network glitch, you can rewind your analysis to properly identify the issue.

Capturing and Storing Every Single Packet with no Packet Loss
This bring us to our last point – being able to capture all of your 10G network data isn’t sufficient; you also need to store the data so that it’s available when you begin identifying issues on the network.

On 1G networks, traditional analysis required a lot of overhead to store network packets, typically using the underlying file system to create and save files, limiting the performance and storage capacity of the appliances.

At 10G+ speeds, organizations must take full advantage of disk space and should even consider connecting their network recorders to a SAN for additional data storage. In return, you’re able to look back at data overnight, and even over a weekend.

Now that we’ve discussed our thoughts on how to better gain visibility into the data traversing your network at 10G+ speeds, we’d love to hear your thoughts on challenges with data visibility at 10G+. And be sure to check out our upcoming webinar for tips on dealing with the transition to faster-speed networks.

Survey Says: We Need More Network Forensics and Real-Time Visibility at 10G!

We launched our 2013 State of Faster Networks survey back in July of this year with the goal of determining exactly how widespread companies’ migration to 10G is and what kinds of problems are being seen along the way.

Over the past few months we compiled your responses and are excited to share them with you. We thank all of you who participated in helping us better understand the footprint of 10G, and we hope the below results help shed some light on how you can fully utilize, and transition to, faster networks.

Who Took the Survey?
We received responses from more than 100 network engineers and IT directors, and as you will see below, the majority of respondents are already supporting 10G networks.

Key Findings
Our survey questions addressed two central topics in relation to faster speed networks: network analysis and network forensics.

The survey found that while many companies support 10G networks (72 percent), network engineers are facing a myriad of challenges in migrating to 10G. For example, 43 percent of respondents cited limited or no network visibility as the biggest challenge in transitioning to faster speed networks. Other challenges respondents cited include:

  • Limitation of security monitoring (21 percent)
  • Lack of real-time network analysis (20 percent)
  • Lack of smart tap compatibility with an existing solution (16 percent)

When it came to network forensics, we found only 31 percent of respondents are implementing some type of network forensics solution in their network, even though 85 percent stated it was essential. What is the reason for such a large discrepancy? Cost is a huge inhibiting factor, with nearly half of respondents identifying cost as the biggest factor in enabling network forensics on high-speed networks.

The below graph details additional challenges with network forensics at 10G: netforensics_graph As we stated before, network forensics is the only solution at 10G. It allows you to quickly solve everything from intermittent network failures to major security risks. Attempting to recreate a network problem is like trying to find a needle in a haystack at 10G! Out of all of our statistics, we were shocked to learn this practice wasn’t more pervasive.

What Does it all Mean?
Now that we’ve seen the results and determined what companies need in order to make the switch to faster networks, what are the next steps? Survey respondents made it clear they need more real-time statistics and faster forensic search times in order to migrate to 10G, yet several factors are stepping in their way.
