Received numerous
comments for
additional test cases
and benchmarking
metrics
Karthik and have posted comments to
mailing list for existing terminology and
methodology
Karthik and have expressed interest in
authoring two new methodologies as part of
this work item
Draft methodologies are completed and
approaching readiness for WG review

Scope of Work Item
4
1.
The IP network layer provides route convergence to protect data traffic against
planned and unplanned failures in the internet.

BWMG has work items to address convergence benchmarking.
2.
Technologies that function at sub-IP layers can be enabled to provide protection of IP
traffic
3.
Sub-IP protection mechanisms include High Availability (HA) stateful failover, Virtual
Router Redundancy Protocol (VRRP), Automatic Protection Switching (APS) for
SONET/SDH, Fast Reroute for Multi-Protocol Label Switching (MPLS), and others.
4.
The metrics for benchmarking the performance of sub-IP protection mechanisms can
be measured at the IP layer, so that the results are always measured in reference to IP
and independent of the specific protection mechanism being used.

Enables different protection mechanisms to be benchmarked and compared

Enables different implementations of the same protection mechanism to be
benchmarked and compared
5.
It is intended that there can exist unique methodology documents for each sub-IP
protection mechanism, such as MPLS Fast Reroute.

•
Appears to be significant interest in BMWG to
author *and review* documents for Sub-IP
Protection Mechanisms Benchmarking work item
•
Is there interest to make this a BMWG work item?
