| # 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 the 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. |
