| 319 | == Testbed Class == |
| 320 | |
| 321 | This class represents a testbed that has allocated resources or from which an allocation is requested. While it is primarily used internally by the federation system, some other applications include a {{{Testbed}}} as a place to attach attributes that pertain to the whole topology. |
| 322 | |
| 323 | It includes the following members: |
| 324 | |
| 325 | {{{uri}}}:: |
| 326 | A string containing the URI on which the testbed can be contacted. Usually a fedd URI. |
| 327 | {{{type}}:: |
| 328 | A string indicating the underlying type of the testbed. Values include "deter," "emulab," and "protoGENI". |
| 329 | {{{interface}}}:: |
| 330 | A list of [TopdlLibrary#InterfaceClass Interface objects] that describe connections of the Testbed to communications substrates. The list may be empty, meaning that the testbed is not connected to any substrates. |
| 331 | {{{attribute}}}:: |
| 332 | A list of [TopdlLibrary#AttributeClass Attribute objects] that are attached to the Testbed. The list may be empty. |
| 333 | {{{localname}}}:: |
| 334 | A list of strings giving alternative names for the testbed. The list may be empty, meaning no such alternatives exist. |
| 335 | {{{status}}}:: |
| 336 | A string indicating the current status of the Testbed (if any). It may also be None, indicating no status is reported. Valid values are |
| 337 | * "empty" - no allocation of resources has been attempted - generally not applied to Testbeds |
| 338 | * "active" - Testbed is functioning as part of an experiment |
| 339 | * "inactive" - Testbed is allocated, but not functioning |
| 340 | * "starting" - Testbed is transitioning from "inactive" to "active" |
| 341 | * "terminating" - Testbed is transitioning from "active" to "inactive" |
| 342 | * "failed" - an allocation of resources has failed - generally not applied to Testbed |
| 343 | {{{service}}}:: |
| 344 | A list of [TopdlLibrary#ServiceClass Service objects] that describe the services this Testbed uses or supplies. These are generally used by the federation system, and their definition is somewhat in flux. The list may be empty. |
| 345 | {{{operation}}}:: |
| 346 | A list of strings that describe the valid operations on the Testbed. These are generally used by the federation system, and their definition is somewhat in flux.The list may be empty. |
| 347 | |
| 348 | The constructor takes the member names as named parameters. |
| 349 | |
| 350 | == Segment Class == |
| 351 | |
| 352 | This class represents a sub-experiment of a federated experiment about which the details are unknown except for its interfaces. It is primarily used internally by teh federation system. |
| 353 | |
| 354 | It has the following members: |
| 355 | |
| 356 | {{{id}}}:: |
| 357 | An [TopdlLibrary#IDClass ID object] that identifies this segment. |
| 358 | {{{type}}}:: |
| 359 | A string indicating the underlying type of the testbed. Values include "deter," "emulab," and "protoGENI". |
| 360 | {{{interface}}}:: |
| 361 | A list of [TopdlLibrary#InterfaceClass Interface objects] that describe connections of the segment to communications substrates. The list may be empty, meaning that the segment is not connected to any substrates. |
| 362 | {{{attribute}}}:: |
| 363 | A list of [TopdlLibrary#AttributeClass Attribute objects] that are attached to the segment. The list may be empty. |
| 364 | |
| 365 | == ID Class == |
| 366 | |
| 367 | This class represents a polymorphic identifier as used by the federation system. At most one of its members is set. |
| 368 | |
| 369 | Those members are: |
| 370 | |
| 371 | {{{fedid}}}:: |
| 372 | A fedid object, representing the hash of a principal key. This represents a [FeddAbout#GlobalIdentifiers:Fedids fedid]. |
| 373 | {{{uuid}}}:: |
| 374 | A string holding a UUID URI. |
| 375 | {{{uri}}}:: |
| 376 | A string holding a generic URI |
| 377 | {{{localname}}}:: |
| 378 | A string holding a locally scoped name |
| 379 | {{{kerberosUsername}}:: |
| 380 | A kerberos user name. |
| 381 | |
| 382 | The constructor accepts the member names as named parameters. |
| 383 | |
| 384 | == Other Class == |
| 385 | |
| 386 | This class represents a topology element that is not captured above. It is a set of interfaces and a place to hang attributes, for use encoding kinds of elements unknown when topdl was specified. |
| 387 | |
| 388 | The members are: |
| 389 | |
| 390 | {{{interface}}}:: |
| 391 | A list of [TopdlLibrary#InterfaceClass Interface objects] that describe connections of the element to communications substrates. The list may be empty, meaning that the element is not connected to any substrates. |
| 392 | {{{attribute}}}:: |
| 393 | A list of [TopdlLibrary#AttributeClass Attribute objects] that are attached to the element. The list may be empty. |
| 394 | |
| 395 | The constructor accepts the member names as named parameters. |
