• GpENI

The Great Plains Environment for Network Innovation – GpENI (pronounced [dʒɛ’pi ni] with accent on the middle

syllable and rhyming with GENI) is an international programmable network testbed centered on a regional optical network between The University of Kansas (KU), Kansas State University (KSU), University of Nebraska – Lincoln (UNL), and University of Missouri – Kansas City within the Great Plains Network (GPN), supported with optical switches from Ciena interconnected by Qwest fiber infrastructure, in collaboration with the Kansas Research and Education Network (KanREN) and Missouri Research and Education Network (MOREnet). GpENI is funded in part by National Science Foundation GENI (Global Environment for Network Innovations) program as part of Cluster B. International expansion has begun anchored on Lancaster University in the UK and ETH Zürich in Switzerland.

• GpENI Topology and Network Infrastructure

GpENI is built upon a multi-wavelength fiber interconnection between four principal GpENI universities within the GPN, with direct connection to the Internet 2 backbone. Administration of Midwest GpENI infrastructure is assisted by GPN, KanREN and MOREnet.

Each university has a GpENI node cluster interconnected to one-another and the rest of GENI by Ethernet VLAN. Additionally, each university is obtaining its own Ciena optical switch for layer-1 and -2 programmable interconnection among GpENI institutions.

GpENI is undergoing significant regional and international expansion, with institutions providing node clusters tunneled (L2TPv3 or IP) into the Midwest optical backbone. We are beginning to explore optical interconnection to some of the international nodes.

I. OVERVIEW

GpENI institutions participate in research projects that benefit from GpENI and GENI experimental capabilities:

• PoMo: Postmodern Internet Architecture (NSF FIND) KU, University of Kentucky, University of Maryland

• MiMANSaS: Matrix, Models and Analysis of Network Security and Survivability (NSF CyberTrust) UMKC, Duke University, University of Pittsburgh

• High Bandwidth Multimedia Applications (NSF CCF) UMKC

• ResumeNet: (EU FP7 FIRE) Resilience and Survivability for Future Networking KU, Lancaster U., ETH Zürich, Techniche Universität München (TUM), Techniche Universiteit Delft, Université de Liège (ULg), Universität Passau, Uppsala Universitet (UU), NEC Labs Heidelberg, France Telecom – Orange Labs.

• G-Lab: German BMBF: TU-Kaiserslautern

• NorNet: Norway INFRASTURKTUR: Simula Research Labs

V. RELATED PROJECTS

• GpENI Node Clusters

38 node clusters are coming up in 17 nations, shown in Figure 1. Each GpENI node cluster consists of several components, physically interconnected by a Gigabit Ethernet switch to allow arbitrary and flexible experiments. GpENI uses KanREN /21 IP address space within the gpeni.net domain. The node cluster is designed to be as flexible as possible at every layer of the protocol stack, and consists of the following components, as shown in Figure 2:

III. GpENI ARCHITECTURE AND INFRASTRUCTURE IV. GpENI PRINCIPAL PARTICIPANTS

• Build a collaborative research infrastructure in the Great Plains region

• Provide programmable network infrastructure enabling GpENI member institutions to conduct experiments in future Internet architecture

• Provide flexible infrastructure to support the GENI program as part of control framework B

• Provide open environment on which the networking research community can run experiments

II. PROJECT GOALS

• GENI Cluster B

GpENI is part of GENI control framework Cluster B. GpENI is one of two network infrastructure projects (along with Mid-Atlantic Crossroads) that will run the PlanetLab control framework and interface with other Cluster B participants, running GUSH experiment control and Raven code deployment.

• GpENI Physical Topology and Infrastructure

The Midwest optical backbone physical topology consists of fiber interconnection between the four GpENI universities, and is currently being deployed, as shown in Figure 3 as white blocks. GpENI-specific infrastructure is depicted by grey blocks; deployment and operational status is described in a subsection below.

Each of the four university node clusters will interface into the GpENI backbone via a Ciena CN4200 or CoreDirector switch. The rest of the GpENI node infrastructure for each site is labeled "GpENI node cluster" The main fiber run between KSU, KU, and Kansas City is Qwest Fiber IRUed (leased) to KU, proceeding to the Internet2 POP, which will provide access to GpENI from Internet2. A chunk of C-band spectrum is planned providing multiple wavelengths at KU and KSU. UMKC is connected over MOREnet (Missouri Research and Education Network) fiber to the Internet2 POP, with four wavelengths anticipated. UNL is also connected to the Intenet2 POP over fiber IRUed from Level3 with two wavelengths committed. Local fiber in Manhattan and Lawrence is leased from Wamego Telephone (WTC) and

Sunflower Broadband (SFBB), respectively. There is abundant dark fiber

already in place on the KU, KSU, UMKC, and UNL campuses to connect the

GpENI nodes to the switches (existing or under deployment) on the GPN fiber

backbone. For reference, the UNL link is terminated by Ekinops switches, the

UMKC link is terminated by ADVA switches, and the KU/KSU link is

terminated by Ciena switches. The current layer 2 connectivity is shown in

Figure 3; note that this is constantly evolving as optical infrastructure is

deployed.

The arrow overlaid on the Figure 2 shows a conceptual flow of an experiment in which the GENI experiment controls the configuration of the PlanetLab, which in turn configures a custom routing protocol, which in turn configures the optical switch configuration.
