Versatility and Breadth of Network Insight is Key for Assuring Digital Experience

Deeper network visibility is just the beginning. Network managers need versatile analyses to solve a broad range of challenges for digital transformation.

Versatility and Breadth of Network Insight is Key for Assuring Digital ExperienceBy Jasmine Noel    November 9, 2018      Thinking

A fundamental aspect of network management is visibility because you can’t analyze what you can’t see. Network teams are finding that depending on maps showing where traffic is flowing is not enough to assure and optimize performance of their increasingly digital businesses. They need more detail to shine a light on complex problems, determine the impact of issues, to understand where to invest for greatest return on optimization, and to enable pinpointing and resolving issues.

According to a recent networking survey, users are looking for solutions that not only find problems but can tell them what the solution is (with some root-cause analysis insight), and in some cases, automate the repair. The problem for operations teams is that most of those problems start as user experience issues:

To paraphrase Scott Perebolte, Sales Engineering Director, unless your network monitoring solution has the breadth of capabilities to help network managers rapidly identify specific application transactions from the beginning, then root cause analysis can be a circuitous journey.

Corvil provides a more direct path to root cause because traffic is analyzed from an application and transaction perspective. Network managers obtain immediate visibility into individual application transactions and see everything associated with it -- database queries, packet sizes, device performance metrics, retransmission requests, etc.. Everything needed to find the root cause is at their fingertips. In the examples listed above, network managers filtered and compared characteristics of individual transactions to discover that:

  • Users only experienced intermittent performance issues because a software bug only affected particularly large data queries from the application to the desktop
  • A bug in the anti-replay DMZ feature, some odd infrastructure configurations and application data being sent between 10GB and 1 GB ports had combined to wreak havoc on application workloads
  • Looping issues were caused by audio codec incompatibilities with one of their voice systems

Corvil's continuous packet capture and L2-L7 network analysis creates a rich source of information for network, IT, security, devops, and business teams. Making that information readily useable in multiple use cases, incorporated into multiple workflows and integrated with multiple other IT and business tools and processes is where the real business value gets created.


In part because of the reduction of capital cost and operating expense of managing multiple, similar network-based tools, savings can be achieved. For example, one firm reduced the physical footprint of its network analytics by 71% by using Corvil to consolidate multiple network monitoring and analysis tools.

The future of networking configuration, orchestration, and automation depends on having excellent insight into how business applications and transactions are interacting with the technology infrastructure. Can one really have “intent based networking” or “software defined networking” without solid analytics capabilities and skills? That’s a topic for another time and blog...

When it comes to assuring service across complex network environments, effective solutions are the ones that network managers find indispensable. A solution’s success or failure will depend on user adoption, determined by the relevance and effectiveness of the capabilities at people’s fingertips, how much insight they receive and the time they save.

But don’t just take my word for it, check out what this recent analyst’s network monitoring report has to say.
