Optimizing Multi-Service Performance

  Multiple services with unique needs share the same physical network:

  The “network state” is not enough

• Pathing decisions need to reflect each service’s performance requirements

• Fewest-hop route is rarely the best; consider network and service-wide view

• Counting packets is not enough information to determine link capacity

Virtualized Networks Pose New Problems

‣ Latency-critical network

functions will need to be

“hosted” close to users

‣ Distributed NFV used in service

chains needs deterministic

connectivity

 Performance must be assured between NFVI hosting-related functions to ensure end-to-end QoE is maintained

Virtualization – Following the Path

Virtualizing functions…easy

Tracking instantiation, mapping

service chains, delivering useful data…hard

Service providers need to be able to track and follow

the service across the entire plane…no matter where it goes

Service Provider Experiences with NFV and SDN

‣ Service providers are deploying NFV/SDN: top use case vE-CPE, vCPE

• Service agility for customers: simple ordering, customized services, fast

delivery; accelerate revenue, improve efficiency, lower cost

• ….but many problems to solve – performance in hybrid networks

‣ Deploy instrumentation layer to make performance-aware orchestration/control

decisions – automation, service assurance

‣ Hybrid end-end (physical virtual physical) service assurance to

isolate segments

‣ NFV services rolling out; new solutions available for new problems
