High Availability With Cisco Active Network Abstraction

Overview

The high-availability characteristics of the Cisco Active Network Abstraction (ANA) system are based on distributed software architecture with internal process monitoring and interunit active-passive clustering and failover. The high-availability solution scales in capacity and performance with the Cisco ANA system, with no performance bottleneck or single point of failure. The high-availability solutions presented herein address local-level high availability for continuous day-to-day operations. Enabling the network management system for disaster recovery is beyond the scope of this discussion.
