One-way/Two-way Active Measurement Protocol Extensions for Performance
Measurement on LAG
draft-li-ippm-otwamp-on-lag-00
Abstract
This document defines extensions to One-way Active Measurement
Protocol (OWAMP), and Two-way Active Measurement Protocol (TWAMP) to
implement performance measurement on every member link of a Link
Aggregation Group (LAG). Knowing the measured metrics of each member
link of a LAG enables operators to enforce a performance metric-based
traffic steering policy across the member links.

1. Problem Statement
Link Aggregation Group (LAG), as defined in [IEEE802.1AX], provides
mechanisms to combine multiple physical links into a single logical
link. This logical link offers higher bandwidth and better
resiliency, because if one of the physical member links fails, the
aggregate logical link can continue to forward traffic over the
remaining operational physical member links.
Usually, when forwarding traffic over a LAG, a hash-based or similar
mechanism is used to load balance the traffic across the LAG member
