Tests are divided 8# into three categories: OUTPUT (evaluates the IOAM processing by the sender), 9# INPUT (evaluates the IOAM processing by the receiver) and GLOBAL (evaluates 10# wider use cases that do not fall into the other two categories). Both OUTPUT 11# and INPUT tests only use a two-node topology (alpha and beta), while GLOBAL 12# tests use the entire three-node topology (alpha, beta, gamma). Each test is 13# documented inside its own handler in the code below. 14# 15# An IOAM domain is configured from Alpha to Gamma but not on the reverse path. 16# When either Beta or Gamma is the destination (depending on the test category), 17# Alpha adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop. 18# 19# 20# +-------------------+ +-------------------+ 21# | | | | 22# | Alpha netns | | Gamma netns | 23# | | | | 24# | +-------------+ | | +-------------+ | 25# | | veth0 | | | | veth0 | | 26# | | db01::2/64 | | | | db02::2/64 | | 27# | +-------------+ | | +-------------+ | 28# | . | | . | 29# +-------------------+ +-------------------+ 30# . . 31# . . 32# . . 33# +----------------------------------------------------+ 34# | . . | 35# | +-------------+ +-------------+ | 36# | | veth0 | | veth1 | | 37# | | db01::1/64 | ................ | db02::1/64 | | 38# | +-------------+ +-------------+ | 39# | | 40# | Beta netns | 41# | | 42# +----------------------------------------------------+ 43# 44# 45# 46# ============================================================= 47# | Alpha - IOAM configuration | 48# +===========================================================+ 49# | Node ID | 1 | 50# +-----------------------------------------------------------+ 51# | Node Wide ID | 11111111 | 52# +-----------------------------------------------------------+ 53# | Ingress ID | 0xffff (default value) | 54# +-----------------------------------------------------------+ 55# | Ingress Wide ID | 0xffffffff (default value) | 56# +-----------------------------------------------------------+ 57# | Egress ID | 101 | 58# +-----------------------------------------------------------+ 59# | Egress Wide ID | 101101 | 60# +-----------------------------------------------------------+ 61# | Namespace Data | 0xdeadbee0 | 62# +-----------------------------------------------------------+ 63# | Namespace Wide Data | 0xcafec0caf00dc0de | 64# +-----------------------------------------------------------+ 65# | Schema ID | 777 | 66# +-----------------------------------------------------------+ 67# | Schema Data | something that will be 4n-aligned | 68# +-----------------------------------------------------------+ 69# 70# 71# ============================================================= 72# | Beta - IOAM configuration | 73# +===========================================================+ 74# | Node ID | 2 | 75# +-----------------------------------------------------------+ 76# | Node Wide ID | 22222222 | 77# +-----------------------------------------------------------+ 78# | Ingress ID | 201 | 79# +-----------------------------------------------------------+ 80# | Ingress Wide ID | 201201 | 81# +-----------------------------------------------------------+ 82# | Egress ID | 202 | 83# +-----------------------------------------------------------+ 84# | Egress Wide ID | 202202 | 85# +-----------------------------------------------------------+ 86# | Namespace Data | 0xdeadbee1 | 87# +-----------------------------------------------------------+ 88# | Namespace Wide Data | 0xcafec0caf11dc0de | 89# +-----------------------------------------------------------+ 90# | Schema ID | 666 | 91# +-----------------------------------------------------------+ 92# | Schema Data | Hello there -Obi | 93# +-----------------------------------------------------------+ 94# 95# 96# ============================================================= 97# | Gamma - IOAM configuration | 98# +===========================================================+ 99# | Node ID | 3 | 100# +-----------------------------------------------------------+ 101# | Node Wide ID | 33333333 | 102# +-----------------------------------------------------------+ 103# | Ingress ID | 301 | 104# +-----------------------------------------------------------+ 105# | Ingress Wide ID | 301301 | 106# +-----------------------------------------------------------+ 107# | Egress ID | 0xffff (default value) | 108# +-----------------------------------------------------------+ 109# | Egress Wide ID | 0xffffffff (default value) | 110# +-----------------------------------------------------------+ 111# | Namespace Data | 0xdeadbee2 | 112# +-----------------------------------------------------------+ 113# | Namespace Wide Data | 0xcafec0caf22dc0de | 114# +-----------------------------------------------------------+ 115# | Schema ID | 0xffffff (= None) | 116# +-----------------------------------------------------------+ 117# | Schema Data | | 118# +-----------------------------------------------------------+ 119 120 121################################################################################ 122# #
