Benchmarking Terminology for Protection
Performance

• Takumi Kimura
• Jerry Perser

55th IETF Atlanta, USA
2
54th IETF - Yokohama

• Takumi Presented automatic protection system
• SONET/SDH rings
• RPR
• Takumi was asked to refine his proposal

55th IETF - Atlanta

• Draft submitted
• http//www.ietf.org/internet-drafts/draft-kimura-p
  rotection-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
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

5
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
  implementations performance

6
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
