GENI MAX Project Status Report

Period: March 19 2011 - August 20, 2011

The reporting period covers the time period March 19, 2011 - August 20, 2011. For Spiral 3, Project Status Reports are due after each GEC. This is the status report following GEC 11.

I. Major accomplishments

A. Milestones achieved

The milestones due during this reporting period are listed below:

MAX.S3.d: MAX is an operational aggregate

  • Transition MAX GENI to an operational aggregate status. This should include:
    • Implementation of the latest GENI AM API
    • Trust at least two GENI clearinghouses
    • Export status information to GMOC
    • Operations support to GMOC as it relates to MAX GENI aggregate


The MAX GENI Aggregate has now transitioned to operational aggregate status. This includes the following capabilities and features:

A high level diagram of the MAX Aggregate Manager architecture is show below.

MAX.S3.e: Demonstration and outreach at GEC11

  • Demonstrate updated MAX Aggregate Manager design, functions, and user interface. This should include demonstration of an operational workflow showing how a GENI researcher goes from initial request, to experiment topology instantiation, to operational support functions, to experiment termination.
  • Demonstrate trust of all four GENI clearinghouses
  • Organize workshop on network stitching (if the community feels a need for such a workshop). This workshop would be similar in focus and objectives to the GEC10 workshop.

We updated our extensive documentation on stitching in general and on a specific GENI Stitching Architecture. This included the following documents:

  • GENI Stitching Description and Examples
  • GENI Network Stitching Architecture - Overview
    • This document provides an overview of a proposed stitching architecture.
  • GENI Network Stitching Architecture - Example
    • This document provides an example of the proposed architecture base on Use Cases.
  • GENI Network Stitching Component Design - Example
    • This document provides an example of a specific design for each of the architecture components. The intent is to convince ourselves that a detailed design can be develop to support the proposed architecture, not necessarily to define the final design details.
  • GENI Network Stitching Schema Example
    • This is an xsd file of an example Common Stitching Topology Schema.
  • GENI Network Stitching RSPEC Instance Example
    • The is an example instantiation of a Stitching Resource Element (Stitching RSPEC info) that an Aggregate would use to describe an external link to another aggregate. In this example, the MAX Aggregate is describing an external link to the ProtoGENI Aggregate. This Stitching RSPEC is in accordance with the above schema.
    • The same Stitching RSPEC instance as above was also formatted in accordance with the ProtoGENI RSPEC v2 schema.

We also organized multiple teleconferences and worked with with various organizations and groups including ProtoGENI, PlanetLab, GPO, OpenFlow, and ORCA/BEN.

B. Deliverables made

Stitching paper development, Stitching Workshop, and GEC11 Demonstration an Outreach. These are documented at the following web sites:

  • Network Stitching Documents:

  • GENI Network Stitching Architecture - Overview
  • GENI Network Stitching Architecture - Example
  • GENI Network Stitching Component Design - Example
  • GENI Network Stitching AM Extension Design Proposal
  • GENI Network Stitching Schema Example
  • GENI Network Stitching RSPEC Instance Example
  • Network Stitching Workshop:

  • GEC11 Demonstration and Outreach: ===> GEC11

II Description of work performed during last quarter

A. Activities and findings

As a result of our initial stitching implementation in the MAX Aggregate Manager users now have the ability to include stitching across ProtoGENI and Internet2 ION infrastructures as part of MAX GENI Slices. We leveraged this work to develop a proposed GENI Stitching Architecture and held multiple conversations with interested parties. Our key finding is that the proposed stitching architecture provides a point from which we can move forward on the development of the general GENI stitching capability.

C. Publications (individual and organizational)

We have produced several internal documents as part of our stitching work:

  • Network Stitching Papers:

D. Outreach activities

We are continuing to reach out to potential GENI users as part of our collaborations with other GENI community members as described in our milestone status above and collaborations section below

E. Collaborations

As part of the activities and milestones described here, we have had extensive collaborations with many in the GENI community. This includes ProtoGENI, PlanetLab, and GPO developers. A large focus of our milestones during this reporting period revolved around network stitching architecture, design, and software development. These activities required collaborations with other GENI aggregate manager developers.
