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.
The types of network tools to empower your network visibility primarily include monitoring and inspection tools that are supported by such components as network taps, packet brokers (NPBs), and bypass switches. Each of these devices has an important function and promotes a comprehensive coverage of all aspects of your network. Depending on the network architectural design – and what works best for your needs – some of the devices are placed in-line or out-of-band, while others are designed to specifically work out-of-band. In some cases, hybrid combinations of the devices are used, that further enhance the visibility.
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.
