Enterprise networks have become complex. They were designed and deployed to
meet a specific set of business requirements at a specific point in time.
Configuration modifications were rare, and manual or semi-automated processes
together with strict change control procedures were enough to maintain
reliability and consistent service levels across the organization.
Business needs have shifted dramatically. The adoption of cloud services,
business application-focused requirements and evolving security policies

More is being required today of network infrastructure than ever before, due
in part to the changing latency and bandwidth needs of modern applications.
Wide area networks ("WANs") are feeling the pressure, especially those that
use many technologies from different services providers, are geographically
diverse and are stretched to the limit by increased video and cloud app
In view of these challenges, hybrid WAN architectures with advanced
application-level traffic routing are of particular interest. They combine
the reliability of private lines for critical business app... (more)
