II. Description of work performed during last quarter

A. Activities and findings

Infrastructure deployment continues in two areas: international build-out (GpENI-MMO) continues with new L2TPv3 tunnels and node clusters operational. Project members participated in GEC7 and demonstrated GpENI. Interconnection and federation with other GpENI projects has begun, including MAX, SPP, ProtoGENI, and OpenFlow. Significant progress continues on the enhancement of the three GpENI sub-aggregates and their integration, as described in the following bullet items. Additional details for each one are provided on the GpENI Milestones and Deliverables page.

  • GpENI integration and management: Integrated portal permitting slices to be created across GpENI PlanetLab and VINI nodes is available for testing purposes. Alternative integration strategies continue to be tested and explored in collaboration with Princeton. Discussions continue with MAX toward DCN sub-aggregate integration with PlanetLab. Nagios monitoring installed, configured, and demonstrated at GEC 7, and Cactus monitoring of KU VLAN switch installed and configured; accounts available on request to selected users with a need to monitor.
  • PlanetLab sub-aggregate: A test version of the GpENI PLC was federated with the public PlanetLab, such that GpENI and public PlanetLab slices could share resources with one-another.
  • Routing and topology sub-aggregate: Progress continues to be made on manual and automatic topology creation in a slice using Quagga. Investigation has begun of XORP as a programmable platform within the routing sub-aggregate, and a XORP instance has been manually created in a VINI slice.
  • DCN sub-aggregate: GpENI–ProtoGENI–MAX interconnection successful and demonstrated with MAX project at GEC7.
  • Physical infrastructure: VLAN interconnection has been established with ProtoGENI in the Kansas City Internet2 PoP, enabling connections with a number of other GENI projects, including SPP. Experimentation has begun with OpenFlow in GpENI. The L2TPv3 tunnel has been established to the IU GMOC, which is now operational and part of GpENI. A number of international node clusters are in the process of coming up, including Karlsruhe, Simula, Bern, and Tampare. Large scale tunnel plans have begun with Lancaster, Bern, ETH, and Simula expected to provide termination for multiple GpENI L2 tunnels.
