Why this session?
We face many network challanges like Keep systems and services running
High to continous availability
High reliability and reduced complexity
Security, multitenancy, extensibility
Cannot keep throwing money at it (CAPEX) Network virtualization, QoS, bandwidth management
Performance (latency, throughput, scalability)
Control Operational cost (OPEX) Reduce complexity
