I&M WG meeting at GEC7

Agenda and Notes

Wednesday, March 17, 2010, 3:30pm - 5:30pm
Room: Presidents 2

3:30pm All
Introductions (5min)

3:35pm Paul Barford (University of Wisconsin)
​Major WG issues and goals (15min)

Goals:

+ An infrastructure for gathering, analyzing and archiving measurements in GENI

• Support for broad range of experiments
  
• Tight integration with control framework(s)
  
• Efficient, easy to use, broadly deployed, diverse capabilities, secure, privacy-aware, etc.
  

+ WG facilitates communication and coordination between I & M projects

• Toward reaching overall goals quickly and effectively
  
• Includes architectures, specifications, partnerships
  

Issues:

+ Architectural (v0.1 on wiki)

• Use cases
  
• Schema
  
• Sensors, components and protocols
  
• UI and integration
  
• Authentication and privacy
  
• torage and analysis
  

+ Practical

• Test and evaluation
  
• Deployment, configuration and support
  

Each of the following speakers was asked to include in their talk a review of how they address the following GENI I&M architecture priority topics:

+ Common terminology; best granularity of functions
+ Measurement data schema; common after MPs, before and within MCs, MDAs; what is included in meta-data?
+ Measurement plane; options; expect nodes with 3 or 2 NICs

3:50pm Jim Griffioen (University of Kentucky)
Instrumentation Tools Project (1642) (15min)

​INSTOOLS: Instrumentation Tools for a ProtoGENI Prototype

Goals:
+ Integrate Univ of Kentucky Emulab into ProtoGENI (completed in year 1)
+ Reimplement Univ of Kentucky Edulab instrumentation and measurement tools to work in the ProtoGENI environment.
+ Support automatic generation of instrumentation and measurement infrastructure on a per-slice basis.

Structure:
+ Measurement Points
+ Measurement Controller

Functional Components

1. Setup: deploy and initialize topology-specific software and services
   
2. Capture: capture measurement data
   
3. Collection: move data to processing/storage environments
   
4. Storage: store data on a temporary, short term, long term, and archival basis
   
5. Processing: filter, convert, aggregate, summarize, etc., data
   
6. Presentation: present data to users in meaningful ways
   
7. Access Protection: protect resources and data
   
8. Measurement Control: Dynamically control the above components
   

Note: Conventional network management solutions exist for 2. through 8.

Mapping functions to proposed services:

1. Setup – MO?
   
2. Capture - MP
   
3. Control – MO?
   
4. Collection - MC
   
5. Storage - MDA
   
6. Processing - MAP
   
7. Access Control – MO?
   
8. Presentation - MAP
   

Measurement data schema:
+ Data-specific formats will exist at multiple times and places but should be invisible to the generic measurement infrastructure
+ Should leverage expertise of those with experience in this area (DatCat, PerfSONAR, etc).

Measurement plane:
+ Virtual interfaces abound in GENI.

• Unknown how virtual interfaces map to physical NICs.
  

+ Shared paths are OK, but require QoS.

• Setting up QoS planes is challenging; particularly if planes are per-slice.
