GpENI Project Status Report

Period: 1Q09

I. Major accomplishments

A. Milestones achieved

We have completed the first two milestones, which have been demonstrated at GEC-4:

  • Purchase switch and complete end-to-end connections: in addition to the first Ciena CoreDirector purchased and installed at UNL, KU, KSU, UNL and UMKC node clusters are all operational
  • GpENI: Integrate GpENI with PlanetLab control framework: The KSU PLC is now able to create slices across all GpENI node clusters; dynamic status and demo at

B. Deliverables made

None due.

II. Description of work performed during last quarter

A. Activities and findings

GpENI Node Cluster
This second quarter has been devoted to making the basic GpENI infrastructure operational and meeting our first two milestones. Major activities included:

  • Installation of KSU, UNL, and UMKC node clusters. Full node cluster details, including DNS names, IP addresses, configuration, and operational status is maintained on the Node Cluster wiki page.
  • DNS redirection for GpENI nodes is operational.
  • IP addresses of GpENI nodes in the KanREN address space are now globally routable. Thus all GpENI nodes are visible to the public Internet.
  • UNL are in contact with Chris Tracy of MANFRED group to control the Ciena CoreDirector switch with DRAGON software, and have received instructions and configuration details. UNL is working on modifying DCN 0.5 to include the support for Netgear GSM7224 switch.
  • UNL received two Ethernet cards from Ciena and they are installed successfully in the CoreDirector. There is a 10 GigE SFP installed in one of the modules. The Cisco ONS15327 Multi-service Provisioning Platform (courtesy of UNL funds) has been rack-mounted and it has a 1 GigE SFP and an OC12 optical interface. The Cisco equipment can be used on the client side to interface with CoreDirector in optical domain. In order to connect to the GpENI network we require 1GigE SFPs and we are in communication with Ciena to obtain them.
  • End-to-end connectivity has been established between all of the GpENI node clusters; KanREN has been instrumental this process. UNL connects to Kansas City via DWDM Lambda, and UMKC is connected to Kansas City with an L2TPv3 VPN tunnel. MOREnet fiber connectivity is expected to come online in a few weeks. In Kansas City, UNL and UMKC are connected to the KanREN MPLS domain, where a VPLS exists that connects Kansas City with KU, KSU over fiber, and a gateway to I2 and the public Internet at the IP layer. All four of the nodes communicate with each other over the same broadcast domain, enabling them to operate on the same network-layer segment. This enables L2 connectivity between all nodes, and the ability to create Layer 3 environments within and between the nodes as necessary for experimentation. KU, KSU, UNL, and information technology have been instrumental in local connectivity.
  • The KSU MyPLC is able to create slices across all of the GpENI node clusters. KSU have created a Web-based application that dynamically shows the status of the PlanetLab node and a demonstration slice that allows arbitrary paths to be set up among GpENI nodes.
  • GUSH is running on GpENI

D. Outreach activities

The GEC-4 demo page is publicly accessible.

James P.G. Sterbenz, Abdul Jabbar, and Justin Rohrer (KU), John Sherrell, Nidhi Tare (KSU) attended GEC-3. Sterbenz reported on GpENI deployment status to the Cluster B meeting. Students Sherrel, Tare, Rohrer, and Jabbar demonstrated GpENI.

E. Collaborations

  • GpENI PIs have continued participation with Cluster B coordination led by Jon Turner at Washington University
  • Byrav Ramamurthy at UNL is continuing direct collaboration with Cluster-B partner Chris Tracy (MAX) in the MANFRED project to use DRAGON control plane software
  • KU and KSU have begun working with Jeannie Albrecht to run GUSH on GpENI, have given her early access to create slices on GpENI.
