# This script evaluates the IOAM insertion for IPv6 by checking the IOAM data
# consistency directly inside packets on the receiver side. Tests are divided
# into three categories: OUTPUT (evaluates the IOAM processing by the sender),
# INPUT (evaluates the IOAM processing by a receiver) and GLOBAL (evaluates
# wider use cases that do not fall into the other two categories). Both OUTPUT
# and INPUT tests only use a two-node topology (alpha and beta), while GLOBAL
# tests use the entire three-node topology (alpha, beta, gamma). Each test is
# documented inside its own handler in the code below.
#
# An IOAM domain is configured from Alpha to Gamma but not on the reverse path.
# When either Beta or Gamma is the destination (depending on the test category),
# Alpha adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop.
