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…
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

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
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
