| 392 | Discussion topics: |
| 393 | Are these five services a complete group of I&M services? |
| 394 | |
| 395 | Are these good names for the five I&M services? |
| 396 | |
| 397 | Is this five the right granularity for I&M services? |
| 398 | |
| 399 | Is this a complete and flexible configuration for I&M services? |
| 400 | |
| 401 | Can this configuration accommodate the range from small-scale to large-scale implementations? |
| 402 | |
| 403 | How can we obtain a consensus, so that we can set a firm foundation for the other topics? |
| 404 | |
| 405 | Interfaces, protocols and schema for measurement data: |
| 406 | |
| 407 | Issues: |
| 408 | This topic suggested at GEC6 meeting: Common schema for MD |
| 409 | Can we identify a common set of interfaces, protocols and schema for MD, or at least a limited number of types? |
| 410 | What needs to be included in the MD schema? |
| 411 | |
| 412 | Approach: |
| 413 | Assume all MD after MPs follows this common set of interfaces, protocols and schema |
| 414 | Start with definition of MD schema |
| 415 | Next, understand [8. MD Transport via GENI Measurement Plane] |
| 416 | Then, complete first set of interfaces and protocols |
| 417 | |
| 418 | From GENI I&M Capabilities Catalog (v0.1), these GENI projects (and others) are working on data schema and/or data archives: |
| 419 | |
| 420 | perfSONAR for network measurements (Swany, Univ Delaware, 1788) |
| 421 | IMF project (Dutta, NC State, 1718) |
| 422 | Embedded Real-Time Measurements (Bergman, Columbia, 1631) |
| 423 | GENI Meta-Operations Center (Herron, Indiana Univ, 1604) |
| 424 | netKarma: GENI Provenance Registry (Pale and Small, Indiana Univ, 1706) |
| 425 | DatCat project at http://www.datcat.org/ (Klaffy, CAIDA) |
| 426 | Crawdad project at http://crawdad.cs.dartmouth.edu/ (Kotz, Dartmouth) |
| 427 | Amazon Simple Storage Service |
| 428 | Data-Intensive Cloud Control (Zink and Cecchet, UMass Amherst, 1709 ) |
| 429 | Experiment Mgmt System (Lannom and Manepalli, CNRI, 1663) |
| 430 | others? |
| 431 | |
| 432 | What can we learn from these projects? |
| 433 | |
| 434 | Discussion topics: |
| 435 | |
| 436 | Standardized interfaces between measurement services |
| 437 | Pt-to-pt vs pt-to-multipoint (e.g., pub/sub) |
| 438 | Stream vs bulk transfer |
| 439 | Disconnection operation expected, or not. |
| 440 | |
| 441 | Protocols for moving measurement data |
| 442 | Streaming data |
| 443 | Bulk-transfer of data |
| 444 | |
| 445 | Schema for measurement data |
| 446 | Data record identifier |
| 447 | Annotation, or meta data |
| 448 | Data types and values, with timestamps |
| 449 | |
| 450 | How can we obtain a consensus on first set of intfc’s/protocols/schema for MD? |
| 451 | |
| 452 | What is the process for extending the set? |
| 453 | |
| 454 | |
| 455 | GENI measurement plane: |
| 456 | |
| 457 | Issue: |
| 458 | Need to understand how MD traffic flows are transported by the GENI Measurement Plane before the interfaces and protocols for MD can be fully defined |
| 459 | |
| 460 | Approach: |
| 461 | Understand current view of GENI Control Plane and Experiment Plane |
| 462 | Consider options for GENI Measurement Plane to transport MD flows, using networks that implement GENI Control and Experiment Planes |
