| # This script evaluates IOAM for IPv6 by checking local IOAM configurations and |
| # IOAM data inside packets. There are three categories of tests: LOCAL, OUTPUT, |
| # and INPUT. The former (LOCAL) checks all IOAM related configurations locally |
| # without sending packets. OUTPUT tests verify the processing of an IOAM |
| # encapsulating node, while INPUT tests verify the processing of an IOAM transit |
| # node. Both OUTPUT and INPUT tests send packets. Each test is documented inside |
| # its own handler. |
| # |
| # The topology used for OUTPUT and INPUT tests is made of three nodes: |
| # - Alpha (the IOAM encapsulating node) |
| # - Beta (the IOAM transit node) |
| # - Gamma (the receiver) ** |
| # |
| # An IOAM domain is configured from Alpha to Beta, but not on the reverse path. |
| # Alpha adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop. |
| # |
| # ** Gamma is required because ioam6_parser.c uses a packet socket and we need |
| # to see IOAM data inserted by the very last node (Beta), which would happen |
| # _after_ we get a copy of the packet on Beta. Note that using an |
| # IPv6 raw socket with IPV6_RECVHOPOPTS on Beta would not be enough: we also |
| # need to access the IPv6 header to check some fields (e.g., source and |
| # destination addresses), which is not possible in that case. As a |
| # consequence, we need Gamma as a receiver to run ioam6_parser.c which uses a |
| # packet socket. |
