CHALLENGES IN TRANSITIONING TO SDN

How to measure the performance of SDN

network?

How to benchmark SDN components?

Will this new architecture be stable

and reliable?

Will the new architecture meet the

scalability requirements?

How to troubleshoot and monitor the SDN

network?

Will there be interoperability issues

with existing networks?


SDN Applications

Business Applications

Southbound Interface (OpenFlow, NetConf, BGP, SNMP, etc.)

Northbound Interface (REST, SOAP, etc.)

SDN TEST METHODOLOGIES

OpenFlow Conformance

OpenFlow Controller Benchmarking

ONF Conformance Test Specification OpenFlow-1.0.1

IETF Draft - draft-bhuvan-bmwg-of-controller-benchmarking-00

Performance

• Flow set-up rate

• Flow set-up delay

• End-to-End flow set-up duration

Scalability

• OpenFlow connections capability

• Switch scalable limit

• Flow scalable limit

Reliability

• Erroneous OF connection handling

• Denial of service handling

• Controller failover time

• Datapath re-covergence time
