How To Track Performance and Fault in a Multi-layer, Software-Defined Network (SDN) Environment
3 likes1,842 views
This document discusses how to track performance and faults in a multi-layer software-defined network (SDN) environment. It outlines the challenges of assuring SDN/NFV networks due to their complex layering, vulnerability, need for automation/migration, and velocity. It introduces CA's Virtual Network Assurance solution, which provides multi-vendor normalization, relationship mapping between network layers, and an open collector to flexibly monitor SDN environments. Some key features highlighted are overlay-underlay topology visibility, service chain awareness, and integration with CA products like Performance Management and Spectrum. Early adopter use cases are also discussed.

In order to understand monitoring requirements for performance and fault management, you need to have the multi-layer metadata readily available for reconciliation. In this session, we will go through some scenarios and workflows to demonstrate how CA Technologies solutions solves these problems. Timothy Diep CA Technologies Director, Product Management
