Add Network Monitoring Deployment to Your New Year’s Resolutions

With 2015 coming quickly, most businesses are carefully re-examining their goals and objectives in light of new technologies that have proven successful in their industry during the past year or two. If for your company this includes upgrading network speed to support more complex applications—or if you’ve made the change already—deploying network monitoring and network forensics should top your list of New Year’s resolutions.

Moving to 10G or 40G network speed significantly improves your ability to support video, web browsing, email, instant messaging, and other internal and end-user applications. At the same time, however, increasing bandwidth and allowing more traffic to traverse your network makes it more difficult for your network engineer to keep an eye on all activity 24/7.

Best-in-class network monitoring solutions like WildPackets’ OmniPeek Network Analyzer help you tackle this visibility issue with features such as a network traffic dashboard, which allows IT to quickly drill down to the details of any single node. With OmniPeek, your IT team has access to Interactive real-time monitoring of key network statistics, can easily view application vs. network latency, and can instantly drill down to packets.

Additionally, OmniPeek offers sophisticated notifications that alert your IT team when performance drops below a predetermined level. These warnings ensure your engineers can quickly address a small network issue (e.g., like an occasional dropped packet) before it becomes a bigger problem (e.g., significant latency or even a full-fledged outage).

Last but not least, network forensics functions help you avoid or quickly detect and deal with data breaches, cyber attacks, HR violations and other network security issues. Network forensics can capture days or even weeks worth of traffic and give your team 24/7/365 access to all this information for review. These solutions go a long way toward ensuring your organization doesn’t become the next JP Morgan, Target, Home Depot or P.F. Chang’s by providing capabilities such as:

  • Comprehensive data collection: Hours or even days of network traffic—anything that crosses the network, whether email, IM, VoIP, FTP, HTML, or some other application or protocol
  • Flexible data collection: All data gathered on a network segment for future inspection or focus on a specific user or server
  • High-level analysis: Expert analysis, graphical reports, and application performance scoring

Perhaps the best thing about putting network monitoring adoption on your list of resolutions is that you don’t have to rely on your willpower to get it done. Instead, you can put top-notch security measures in place and rest easy all year knowing your network is secure.

Improving Visibility in Virtual Networks

Over the past decade, as networks became increasingly complex and crucial for businesses across all verticals, the IT industry developed new ideas about network design. Virtualization was born out of that process, as businesses—particularly data centers and enterprises maintaining large networks—sought to curb ever-growing hardware-related expenses. Cloud services, built on visualization technology, gradually made their way into the mainstream during that time as well.

Indeed, using virtualization to separate control plane from data plane functions and allowing managers to maintain networks from one or just a few screens can help businesses reduce IT expenses by limiting the space, power and cooling requirements for hardware. But virtualization also limits network visibility, making it nearly impossible to monitor new kinds of traffic, which include:

  • Invisible—remains in the rack and never travels across the physical network, making it difficult to capture
  • Intrahost—involves one physical host and several virtual machines
  • Interhost—where multiple virtual hosts are connected on a virtual fabric, resulting in a collection of virtual systems with only one physical connection to the network

So what can businesses do? Continuing to scale hardware is financially unsustainable, but operating without network visibility is too risky. For businesses stuck between these two undesirable options, WildPackets virtual network analysis solutions can bring back the real-time troubleshooting capability that technicians need to do their jobs effectively. Such bleeding-edge technology continuously monitors critical applications running in virtual environments and notifies IT immediately if a problem arises. The solution also records all network traffic, which can be reviewed at any time.

Virtualization presents new difficulties for network professionals, but these problems do have solutions.

Is Your Wireless Network Feeling Neglected?

During the past several years, businesses have increasingly transitioned from traditional landlines to wireless systems as their primary communications medium. Enterprises and SMBs alike are embracing the 802.11ac standard, which expands wireless network capacity and reliability.

But in much the same way that faster wired networks are proving challenging to manage, wireless networks are presenting engineers with new security and performance problems of their own.

Along with the ability run more complex, intricate business applications on wireless networks than ever before comes the need for real-time troubleshooting. In particular, businesses transferring more data at faster speeds for BYOD, video or voice over Wireless (VoFi) need a wireless network analyzer to help IT departments keep these mission-critical services up and running. When an application experiences even short-lived latency, let alone significant downtime, productivity falls right along with network speed.

WildPackets’ wireless network monitoring solutions provide engineers the high-level visibility they need to snuff out any potential issues—from security vulnerabilities to traffic overload—before they become catastrophes. WildPackets can help companies reduce downtime or other network disturbances by providing:

  • 24/7 real-time analysis of everything on the network
  • Capture of network traffic from multiple channels simultaneously
  • The ability to track mobile users as they move to new channels and access points
  • The capability to track wireless conversations, authentications and other events to ensure only authorized users gain access
  • Sophisticated alerts and notifications to potential problems
  • Pinpointing of the precise source of any problem
