Virtualizing telconetwork functions› Improving time-to-market
– minimizing the typical network operator cycle of innovation.
› Optimizing resource utilization– reduce equipment cost, space, and power
consumption.
› Improving operational efficiency – automation and intelligent platforms.
› Elasticity and scalability– Dynamic demands imposed in a multi-tenant
environment.
› Encouraging openness– Enable multi-vendor interoperability of hardware and
software.

Telco Cloud Execution EnvironmentRationale
1. Stringent performance requirements– Network throughput, latency– Real-time scheduling in the
hypervisor– Load balancing
2. High availability– High availability for the execution
environment – High availability for the
applications3. Fault and performance
management 4. Security and isolation
– Including performance isolation– Specific firewall rules and
configurations5. SLA guarantees and fulfillment
