This document summarizes a panel discussion on orchestrating the lifecycle of network services. It outlines the challenges of automating service design and deployment across test and production networks. Historically, engineering and operations teams have worked independently, but there is now a need for greater collaboration and new tools to support their workflows through the complete lifecycle from design to retirement. The panel explores this topic and diagrams show different frameworks for orchestration layers, architectures, taxonomies, and the DevOps lifecycle for network functions virtualization. Audience polling gauges views on the future of orchestration approaches.

Outline
• Automating service design and deployment across test and
production networks brings new challenges for engineers and
operations staff.
• While these teams have historically acted independently, there is a
need for greater collaboration going forward and a need for new tools
to support their workflows.
• This panel will explore the challenges and opportunities of
orchestrating the complete lifecycle of network services from design to
retirement.

Existing OSS
NFVO
e.g. E2E service like VoLTE
NS is built from interconnected VNFs and PNFs
NSO and RO are resource-oriented, application
agnostic, management functions and are not
intended to be implemented separately.

Orchestration, Automation & DevOps
Orchestrators & Controllers:
•Service lifecycle management (moves, adds, changes,
disconnects)
•Large-scale, dynamic changes enabled by model-based
approach
•Device agnostic management of services across the network
Orchestration
Automation System:
• Consolidation of scripting tools, orchestrators, & controllers into
single management plane
• Network Intent API capabilities for upstream services such as
CRM & IT Service Management
• Closed-loop automation leveraging monitoring, inventory,
telemetry, and analytics data within automation workflows
Automation
Scripts & DevOps Platforms:
• Large-scale changes, but rigid in the scope of each change
• Transition of scripts to DevOps platforms to increase reusability
• Standardized approach leveraging run books and vendor
specific modules
DevOps Tools

Audience Question Poll
Which of the following best fits your view?
• I foresee a multi-layered approach to
orchestration with one end-to-end orchestrator
overseeing a number of domain specific
orchestrators
• I foresee a zoo of orchestrators from multiple
suppliers that require significant manual effort
to work in tandem and/or custom integration
• Too soon to say, too hard to tell
