SDN Transport API Interoperability Demo with OIF and ONF

2016 SDN Transport APIInteroperability Demonstration

Jonathan Sadler (Coriant)Interop Working Group Chair

OIF Technical CommitteeOpenNetworkingFoundation

Agenda

MotivationObjectivesOverview of TestsDeep 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 use50ms protection all the time

300% Capacity use50ms 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

Test Case tracking

12

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 isnecessary in NFV deploymentsinvolving the transport layer• Best technology for carrying service• Support multiple provider networks

T-API provides interface requiredby WAN Infrastructure Manager• Integrates Transport into MANO

FINDINGS

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
