- 9. © 2015 IHS 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 MME / MTSO Data Center SDN / SON Controller Real-Time, Ubiquitous, Open Performance Visibility Missing Latency ● Delay Variation ● QoS/E KPIs Utilization ● Available Capacity ● Packet Loss Best Effort Latency Sensitive Bandwidth Hungry The “Network State+” 9
- 10. © 2015 IHS 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 MME / MTSO NFVI Hardware-based µs measurement precision will be required < 500 µs Latency VNF Chaining Performance 10
