Analyze Assure Accelerate Benchmarking Terminology for Protection Performance Takumi Kimura Jerry Perser 55 th IETF Atlanta, USA
2
Analyze Assure Accelerate 54th IETF - Yokohama Takumi Presented automatic protection system – SONET/SDH rings – RPR Takumi was asked to refine his proposal OADM Light path Protection Protection trigger OADM Sender RouterReceiver Router System Under Test (SUT)
3
Analyze Assure Accelerate 55th IETF - Atlanta Draft submitted – http://www.ietf.org/internet-drafts/draft-kimura- protection-term-00.txt – Draft 00 contains non technology-specific parts. technology-specific parts (SONET/SDH APS, etc.) will be added Still focused on SONET/SDH rings – Should we focus on measuring sub-IP protection schemes on IP performance? – Include MPLS, Spanning Tree, etc…
4
Analyze Assure Accelerate Several Advantages Not limited to SONET/SDH APS – Adopt to MPLS by using a different trigger Measures the effect of failover on IP – Other drafts concentrate on control plane only Observes more than packet loss Dropped packets Induced delay Out-of-order packets Duplicate packets 12 34567 12 3 4 56 4 1267 12 34
5
Analyze Assure Accelerate Motivation Different Protection technologies – Automatic Protection Switching (APS) for SONET/SDH – Resilient Packet Ring (RPR) for Ethernet – Fast Reroute for Multi-Protocol Label Switching (MPLS) Recovery timing in IP-layer is different from that in sub-IP layer. Standard Testing methodology to compare implementation’s performance
6
Analyze Assure Accelerate Goals Set focus on ? – SDH performance, or sub IP technologies Incorporate different topologies Incorporate different protection types Add technology-specific part (especially, SONET/SDH APS) to the draft Move draft from Individual work to BMWG working draft
