Scope

This project will develop and deploy the GIMI instrumentation and measurement framework, capable of supporting the needs of both GENI experimenters and GENI infrastructure operators. It uses the ORBIT Measurement Library (OML) and integrated Rule Oriented Data System (iRODS) as its basis. It will provide libraries to instrument resources, to filter and process measurement flows, and to consume measurement flows. It will use the iRODS data grid for archiving and further processing. It will include access control based on accepted GENI policy and authorization mechanisms.

Strategy and Goals

Its first goal is to provide easy-to-use I&M services for experimenters, who are deploying slices in GENI on selected types of servers, VMs and racks, interconnected by various types of network paths.
Its second goal is to provide comprehensive infrastructure measurement services for infrastructure operators, who are deploying measurement slices on selected types of servers, VMs and racks, interconnected by a various types of network paths. In addition, slices established by other infrastructure operators, or by experimenters, can be authorized to gather data from the measurement slices.

This project will build and operate two persistent services: the GENI Measurement Data Archive service (i.e., iRODs)and the GENI Experimenter Portal Service. These can be utilized by all types of GENI I&M services, including those developed in the GEMINI project. The GENI Experimenter Portal Service will be developed in cooperation with the GEMINI project, to support both GIMI and GEMINI tools. This project will use the GENI Measurement Data Object Descriptor (MDOD) schema, defined for use by all GENI I&M services.

It may utilize two persistent services provided by the GEMINI project: the GENI Global I&M Registry (i.e., UNIS), and the GENI Event Messaging Service.

The GIMI project will use the configuration shown in the diagram below.

Operational Capabilities

Milestones

a) Define MeasurementDataObjectDescriptor (MDOD) schema, plus naming of objects and object registry, in collaboration with I&M teams and the GPO. (March 2012, GEC13)

b) Define v0.5 I&M use cases for experiments and infrastructure monitoring, in collaboration with I&M teams, the GPO, experimenters and operators/GMOC. (February 2012)

c) Develop reference v1.0 experiment control tools based on OMF and Gush (including OMNI) and document the interfaces, protocols, and APIs of these tools, in collaboration with I&M teams and the GPO. (March 2012, GEC13)

d) Description of ontology extensions to cover measurement point resources (software and hardware). This will be integrated into ORCA per the ORCA-AUG SOW. (February 2012)

e) Identify use cases and concept of operations for GENI messaging services, in cooperation with the IMF and GEMINI projects. (March 2012, GEC13)

f) Deliver v0.5 definition of GIMI architecture and software modules for year 1, documented on GIMI web page. (February 2012)

g) OML Release 2.7.0: (February 2012)

  1. Fixing of current bugs affecting client apps or user's interpretation of data
  1. Fixing of current deployment and user development issues
  1. New features to improve measurement reporting and future analysis
  1. New features to ease current usage and enable future features
  1. Improved documentation

h) Agree on v1.0 I&M use cases for experiments and infrastructure monitoring, in collaboration with I&M teams and the GPO, and document, including: (March 2012, GEC13)

  1. WiMax
  1. LEARN/BEN layer 0,1 or 2 real-time measurements
  1. Sensor network (radars, power monitors)
  1. Measure DiCloud workflow

i) Compare available technology and prototypes for GENI messaging services, in cooperation with the IMF and GEMINI projects. (March 2012, GEC13)

  1. Decide whether GENI Event Messaging Service being developed for GEMINI project could be used by GIMI tools.

j) Agree on v1.0 definition of GIMI architecture and software modules for year 1 with the GPO, and document on GIMI web page. (March 2012, GEC13)

k) Identify necessary mappings between iRods metadata catalog information and MDOD. (March 2012, GEC13)

  1. MDOD will be created and edited as part of measurement orchestration, to be completed in Year 2 (Spiral 5).

l) Agree on v1.0 target GENI environment for GIMI tools with I&M teams and the GPO (March 2012, GEC13)

  1. Nominal v1.0 target aggregate is ORCA and ExoGENI racks; both servers and VMs; when VMs have private IP addresses, make use of RENCI’s proxy mechanism, which basically works like an automated NAT.
  1. GIMI tools will come with an image; create template images with a basic configuration of tools which can be used and modified by other experimenters.
  1. GIMI tools will be configured via OMF.

m) Deliver Beta 1.0 of GIMI software (June 2012)

  1. Utilize XML messaging service based on XMPP
  1. Utilize OML servers that are part of the software release, and are run as part of the slice.

  1. Visualization is provided by a standalone tool, that is run as part of the slice.

  1. Demonstrate GIMI working on target aggregates, including ORCA and ExoGENI racks (if available), both servers and VMs.
  2. Demonstrate some WiMAX measurement capabilities.
  3. Demonstrate Layer 0,1 or 2 measurement capabilities (potentially a combined LEARN/CASA measurement depending on radar deployment in DFW)
  4. If installed, demonstrate initial capabilities to monitor racks.
