InstaGENI Aggregate

Case Western Reserve University InstaGENI

This InstaGENI aggregate supports the GENI Aggregate Provider Agreement (09/08/2014).

InstaGENI Aggregate Overview

Aggregate Manager URL https://geni.case.edu:12369/protogeni/xmlrpc/am
Aggregate Manager URN urn:publicid:IDN+geni.case.edu+authority+cm
Aggregate Manager Common Name cwru-ig
Aggregate Resources An InstaGENI aggregate includes 5 Hosts (3 VM Servers and 2 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.

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.

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