Spiral Development The GENI project evolves through a well-structured, adaptive process

•  An achievable Spiral 1 Rev 1 control frameworks, federation of multiple substrates (clusters, wireless, regional / national optical net with early GENI ‘routers’, perhaps some existing testbeds), Rev 1 user interface and instrumentation.

•  Envisioned ultimate goal Example: Planning Group’s desired GENI facility suite, probably trimmed some ways and expanded others. Incorporates large-scale distributed computing resources, high-speed backbone nodes, nationwide optical networks, wireless & sensor nets, etc.

•  Spiral Development Process Re-evaluate goals and technologies yearly by a systematic process, decide what to prototype and build next.

Create my slice

Goal #1 Fund multiple, competing teams to develop GENI Clearinghouse technology, encourage strong competition within the first few spirals

Goal #2 Demonstrate end-to-end slices across representative samples of the major substrates / technologies envisioned in GENI; Spiral 1 employs VLANs as “low hanging fruit”


GENI Spiral 1 creates an early, nation-wide “native mode” GENI prototype suite as the framework for later spirals of integration and refinement.

Spiral 1 extensively leverages existing infrastructure and NSF-funded efforts


A caveat GENI Spiral 1 will be very early prototyping!

•  We are not trying to build a “real GENI” with these D&P efforts!

•  We are trying to build a series of exploratory prototypes that will help the GPO, and the community as a whole, better understand the design space, risks, and potential research benefits of such facilities.

•  We are attempting to gain insight and perform first explorations – not construct a production system.






•  Summary


GENI Spiral 1Overview

•  Competing approaches to the GENI control framework •  Prototypes of cutting-edge technology to implement slices, GENI’s

key virtualization feature, including sliceable switches, Ethernets, computing and server, optical equipment, wireless nodes, sensors, and the beginnings of sliceable FPGAs

•  Interconnected national backbones, regional networks, and campus networks that can try out “native mode GENI” in Ethernet frames, thus allowing non-IP experimentation across wide-area slices

•  Tools and techniques for user opt-in •  GPO system engineering and integration

GENI System Decomposition Overview






•  Summary


CREATE GENI SPIRAL 1—Integrate Across Projects and Technologies

•  Integrate end-to-end data (experiment), control, measurement, and basic O&M functions at most sites.

•  Integrate programmable GENI nodes in multiple substrate types including at least 2 major backbones, regional optical networks, campus networks, and wireless infrastructures.

•  Integrate connections from campus/subscriber sites to programmable nodes in different substrates, enabling GENI "native mode" parts of Spiral 1. ("Native mode" won't extend to arbitrary Internet end users in Spiral 1)

•  Integrate IP connectivity to/from GENI infrastructure. •  Support users and traffic for live experiments in Spiral 1.

Spiral 1 Integration Priority Goals


Spiral 1 Integration Priority Goals (cont)

STIMULATE BROAD COMMUNITY PARTICIPATION—Build Control Plane and Tools

•  Integrate 27 projects in 5 prototype control frameworks. Show basic control functions operating between group members. We expect multiple users for each reference Clearinghouse and Component/Aggregate Manager software implementation.

•  Operate multiple prototype Clearinghouses. (Operations between clearinghouses, is desirable, but not a priority for Spiral 1.)

•  Develop Spiral 1 security design, security policies, and O&M policies for all deployed GENI infrastructure

•  Provide researcher helper tools and measurement tools

BUILD A STRONG INDUSTRIAL/ACADEMIC BASE—Encourage Active Use

•  Support active research experiment(s) in each clearinghouse. Spiral 1 researchers will be early adopters from outside the developer community.

•  Integrate academic and commercial infrastructures in projects •  Plan for large-scale commercial and academic environments

Internet2 Backbone Node Connection

•  Internet2 will provide GENI a 10Gbps wave over the full Internet2 network footprint

–  Infinera transport equipment interfaces the network line side using the Optical Transport Network (OTN) standard at the OTU-2 level (10Gbps)

–  Infinera transport equipment interfaces the client line side with either GbE or 10GbE interfaces (among others e.g. SONET OC-n)

–  Indiana GRNOC demarcation at Ethernet IF to Infinera transport

•  Internet2 access (Infinera Transport) doesn’t allow optical experimentation •  GENI node/subnet connections through additional Ethernet switch

Spiral 1 Integration Status

October 6, 2008






•  Summary


GENI Spiral 1 •  Provides the very first, national-scale prototype of an interoperable

facility suite for Network Science and Engineering experiments

•  Creates an end-to-end GENI prototype in 6-12 months with broad academic and industrial participation, while encouraging strong competition in the design and implementation of GENI’s control framework and clearinghouse

•  Includes multiple national backbones and regional optical networks, campuses, compute and storage clusters, metropolitan wireless and sensor networks, instrumentation and measurement, and user opt-in

•  Early Spiral 1 “native mode” GENI prototype suite will support early live experiments, and provide the framework for later spirals of integration and refinement.

Nothing like GENI has ever existed; the integrated, end-to-end, virtualized, and sliceable set of facilities created in Spiral 1 will be entirely novel.
