| 84 | |
| 85 | |
| 86 | === 2) Obtain slice of GENI resources, install I&M tools and experiment services === |
| 87 | |
| 88 | 2.1) Select target aggregates |
| 89 | |
| 90 | 2.2) Select desired software images/packages for I&M tools and experiment services |
| 91 | |
| 92 | 2.3) Obtain certs, credentials, passwords and keys |
| 93 | |
| 94 | 2.4) Formulate slice topology for experiment, and build request rspec |
| 95 | |
| 96 | 2.5) Acquire resources and load images/packages for I&M tools and experiment services |
| 97 | |
| 98 | 2.6) Start selected software processes |
| 99 | |
| 100 | 2.7) Confirm slice with installed I&M tools and experiment services |
| 101 | |
| 102 | |
| 103 | === 3) Configure I&M tools and experiment services === |
| 104 | |
| 105 | 3.1) Configure selected I&M services |
| 106 | |
| 107 | - objectives: |
| 108 | - binds services together, e.g., between each MP and the MC |
| 109 | - configures baseline services |
| 110 | - verifies that they are ready to run |
| 111 | |
| 112 | - at completion: configured I&M services, ready to run and collect data |
| 113 | |
| 114 | |
| 115 | 3.2) Configure selected experiment services |
| 116 | |
| 117 | - objectives: |
| 118 | - binds services together to realize overall reference/actual experiment |
| 119 | - configures baseline services |
| 120 | - verifies that they are ready to run |
| 121 | |
| 122 | - at completion: configured experiment services, ready to run and process data, which can be observed by I&M services |
| 123 | |
| 124 | |
| 125 | === 4) Run and orchestrate I&M services and experiment services to complete run of experiment === |
| 126 | |
| 127 | |
| 128 | 4.1) Initial setup: start basic host measurements and basic ping active network measurements |
| 129 | |
| 130 | - objectives: |
| 131 | - verify functionality of hosts |
| 132 | - verify topology of slice |
| 133 | |
| 134 | - observe measurements with a real-time presentation service |
| 135 | |
| 136 | - continue measurements throughout duration of the test/tutorial/experiment |
| 137 | |
| 138 | - at completion: |
| 139 | - functionality of hosts and topology of slice has been verified throughout duration of the experiment |
| 140 | |
| 141 | |
| 142 | 4.2) Continuity test: for a limited time, run iperf active network measurements |
| 143 | |
| 144 | - objectives: |
| 145 | - verify ability of slice to carry traffic expected from experiment |
| 146 | |
| 147 | - observe measurements with a real-time presentation service |
| 148 | |
| 149 | - once satisfactory measurements have been observed, stop continuity test |
| 150 | |
| 151 | - at completion: |
| 152 | - capability of slice to carry traffic expected from experiment has been verified |
| 153 | |
| 154 | |
| 155 | 4.3) Instrument and run experiment: |
| 156 | |
| 157 | - objectives: |
| 158 | - gather measurements during experiment that allow experiment goals to be met |
| 159 | |
| 160 | - include desired measurement points within hosts and/or experiment services to instrument test/tutorial/experiment |
| 161 | |
| 162 | - begin to run and orchestrate measurement services |
| 163 | |
| 164 | - begin to run and orchestrate experiment services |
| 165 | |
| 166 | - observe measurements with a real-time presentation service, to verify expected operation of experiment |
| 167 | |
| 168 | - collect all measurements for duration of experiment |
| 169 | |
| 170 | - stop experiment services, when this run of the experiment has been completed |
| 171 | |
| 172 | - stop measurement services |
| 173 | |
| 174 | - at completion: |
| 175 | - one run of experiment has been completed |
| 176 | - real-time look at measurements has verfied expected operation of experiment |
| 177 | - a full set of measurements has been collected, for later analysis and presentation |
| 178 | - collected measurments have been transfered to storage service, so that slice resources can be released (if desired) |
| 179 | |
| 180 | 4.4) Store collected measurements and other artifacts from test/tutorial/experiment in storage service |
| 181 | |
| 182 | - at completion: |
| 183 | - collected measurements and other artifacts have been transfered to storage service |
| 184 | - collected measurements and other artifacts are available for later analysis |
| 185 | - slice resources can then be released at any time, without loss of any measurements or artifacts |
| 186 | |
| 187 | === 5) Analyze and visualize measurement results after completing run of experiment === |
| 188 | |
| 189 | - if necessary, retrieve measurement results from archive service |
| 190 | |
| 191 | - analyze and format results as desired, for visualization with presentation service |
| 192 | |
| 193 | - as appropriate, store analyzed results and/or visualization in storage service |
| 194 | |
| 195 | |
| 196 | === 6) Move selected collected measurements and other artifacts from storage service to long-term archive service === |
| 197 | |
| 198 | - identify archived objects with peristent identifier |
| 199 | |
| 200 | - include policy for sharing with others |
| 201 | |
| 202 | - allow retrieval for further analysis and visualization |
| 203 | |
| 204 | |
| 205 | === 7) Release experiment resources === |
