Agenda
Motivation
Objectives
Overview of Tests
Deep Dive into API messaging
• Topology
• Connection Setup
• Hierarchical Abstraction
Findings and Summary

SDN improves Transport Control
Eliminate “One-size-fits-all” solutions
• NE-behaviors may not match
carrier requirements
• Example
• Combined Reroute and Protection
Programmability enables carrier requirements to be met
400% Capacity use
50ms protection all the time
300% Capacity use
50ms protection switch first fault
~300ms switch second and subsequent
2

Open APIs between SDN Components
How can programmability be provided?

Evaluate current state of SDN in Transport industry
• Validate APIs in SDN Framework
• Useful:
• Do the defined API solve a business problem?
• Is the API consistent with business structural boundaries?
• Perform well:
• Would a different API improve performance?
• Can be implemented

Use Case: MultiDomain Orchestration
Service provider equipment is in different domains
• Different Geographies
• Different Vendors
• Different Technologies
Services cross domain boundaries
• Orchestration across domains is necessary
13

NFV POC
Multi-domain Orchestration is
necessary in NFV deployments
involving the transport layer
• Best technology for carrying service
• Support multiple provider networks
T-API provides interface required
by WAN Infrastructure Manager
• Integrates Transport into MANO

Findings
ONF’s T-API provides functions necessary for multi-domain orchestration
• Topology view
• Connection establishment
• Topology abstraction
ONF’s T-API localizes interoperability to Orchestrator/Controller interface
• GMPLS requires NEs in a sequence to have a consistent behavior in order to
achieve interoperability
ONF’s T-API supports multiple technologies
• Ethernet
• OTN
• DWDM44

Findings
Controllers abstract the network in different ways
• E.g. Unidirectional vs Bidirectional links
Controllers provide/report different capabilities
• E.g. Connectivity restrictions
Division of responsibility between controllers unclear
• E.g. Multi-domain Path Computation
Maintaining RPC and REST styles is confusing
• Not all implementations supported both styles
45

Findings
T-API needs to be validated for additional use cases
• Use of topology interface for Path Computation
• Service Management interface
T-API evolution is needed to meet current Transport Network uses
• Protected Services
• Generalized Notification Service
Based on demo feedback, ONF will align T-API with YANG Best Practices
• Object ID format and lifecycle
• Separation of Configuration, Operational Data
46

Summary
Demonstration shows:
• Cooperation between 17 companies
• 7 Carriers (5 Host, 2 Consulting)
• 10 Vendors
• 2 Research Institutions
• Transport SDN is becoming real
• ONF T-API Specification published, implemented and tested
• Testing is a success
• Identified strengths and areas for further activity
Next step:
• T-API 2.0
