US Ignite InstaGENI Aggregate

University of Vermont

This US Ignite InstaGENI aggregate supports the GENI Aggregate Provider Agreement (05/11/2017).

InstaGENI Aggregate Overview

Aggregate Manager URL https://instageni.uvm.edu:12369/protogeni/xmlrpc/am
Aggregate Manager URN urn:publicid:IDN+instageni.uvm.edu+authority+cm
Aggregate Manager Common Name uvm-ig
Aggregate Resources An US Ignite InstaGENI aggregate includes 5 Hosts (3 VM Servers and 2 dedicated PCs) that can load experimenter specified OS images. Racks also support OpenFlow 1.3 topologies, usually including extensions onto campus OpenFlow networks. Rack servers are HP ProLiant DL380p Gen9.
Typical Experiments InstaGENI provides a controllable, predictable, and repeatable network environment. Experimenters can get virtual machines or dedicated PCs on which they have full "root" access, run available operating systems of their choice, and connect nodes in an arbitrary topology that can support OpenFlow 1.3.

OpenFlow over GENI Network Stitching

This rack supports running hardware OpenFlow experiments over stitched GENI network connections. Please be advised that the following restrictions apply:

  • Network stitching on the InstaGENI rack allocates and enforces link bandwidth, which cannot be modified by OpenFlow.
  • VLANs allocated to stitched connections on the rack cannot be modified, because InstaGENI rack switches operate in hybrid mode, preventing VLAN tag rewriting.

This rack supports OpenFlow 1.3 protocol experiments.

The following is the layout of OpenFlow switch connections for the InstaGENI Aggregate. Shown are the OpenFlow Switches:

  • InstaGENI Switch procurve2: Model: HP J9850A Switch 5406Rzl2
