InstaGENI Aggregate

Virginia Tech

This InstaGENI aggregate supports the GENI Aggregate Provider Agreement (05/12/2015).

InstaGENI Aggregate Overview

Aggregate Manager URL https://foam.instageni.arc.vt.edu:3626/foam/gapi/2
Aggregate Manager URN urn:publicid:IDN+openflow:foam:foam.instageni.arc.vt.edu+authority+am
Aggregate Manager Common Name vt-ig-of
Aggregate Resources An InstaGENI aggregate includes 12 Hosts (3 VM Servers and 9 dedicated PCs) that can load experimenter specified OS images. Racks also support OpenFlow topologies, usually including extensions onto campus OpenFlow networks. Rack servers are HP ProLiant DL380p Gen8.
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.
Sample RSpecs Link to RSpecs used successfully for rack site confirmation tests.
Aggregate Status Restricted access to monitoring at http://genimon.uky.edu and GMOC
Slice Authorities Recognized GENI Portal (https://portal.geni.net), ProtoGENI (http://www.emulab.net)
Usage Policies A GENI Recommended Use Policy is available. Site should also add links here to their own usage policies.
Layer 2 Connectivity Internet2 AL2S network via Mid-Atlantic Research and Education Exchange (MREX). This site does not support GENI Meso-scale VLANs.

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.

If you require some other type of dataplane connections for your OpenFlow experiment, please contact geni-users@googlegroups.com.
