Transformation to Enable Opportunity
Service Innovation is
changing in a 5G World
● Agile/DevOps will Create
Services Faster
● Service Composition Needs
will Increase in Variation
● Improve Service Delivery
Times
Optimization Needed to
Improve Bottomline
● Efficiencies
● Commoditize Resources
● Scale in Heterogeneous
Environments
Digital Transformation
Requires Dynamism
● Intent-based
● No Silos
● Reduce Complexity

5G and Future
• 5G architecture adds agility to Telco network to meet the
critical requirements of business needs
• Emerging Business needs can vary depending on the
type of services they offer
• Ultra Reliable Low Latency Communication - Delay/
Jitter sensitive
• Massive IoT - Reliability sensitive
• Enhanced Mobile Broadband - Bandwidth sensitive
• The above requirements call for the network to be
composable based on the intent
• This calls for the software architecture driving 5G to be
cloud-enabled and microservices based

Payloads handled by
NSM
- Derived from Service Mesh pattern
- Why not allow users to choose from named L2 & L3 services the exact same way?
