What is Network Visibility?

Network visibility is becoming more and more important as organizations face the challenges of deploying increasingly complex network services (such as security, performance management, and monitoring) on an ever-evolving and expanding network and data center architecture. 

In an ideal world, you would cover every link to prevent blind spots in your network visibility layer. However, due to issues like budget constraints or port limitations, this may not be possible. So you should prioritize visibility on the high capacity links and other critical points on your network. A central visibility controller management system can serve as a force multiplier on the links that you have covered.

What is network visibility adaptation layer?
It is the set of network elements and management system that allows network administrators to achieve pervasive visibility into every part of their network.

Achieving Pervasiveness of
your network visibility

The key to ensuring proper network visibility is creating a network visibility layer that comprises strategically placed network Taps, network bypasses, and packet brokers. This kind of comprehensive visibility is called “Pervasive”.
A pervasive visibility layer not only increases network security, but also holds key advantages in reducing downtime in maintenance periods, improving network service recovery time, and increasing your overall ROI. If your network visibility layer is not pervasive, you risk blind spots, potentially compromising your security and network efficiency.
For pervasive network visibility, it is vital that you approach the visibility layer with a cohesive strategy that takes into account the current status of your network, and areas where your network may grow or the topology may change.
