GENI Network Core subnet reservations

The GENI OpenFlow-controlled network core is often sliced by IP subnet, so this page tracks which subnets are reserved for what purposes.

A set of these subnets ( below) is attached to a number of MyPLC-controlled PlanetLab testbeds. Each node in these testbeds is configured with IP addresses (see below for a table of those addresses) on each of several pre-provisioned dataplane IP subnets. This configuration allows experimenters to reserve slivers on each of these testbeds, reserve OpenFlow resources, and perform OpenFlow-based experiments.

The HelloGENI page describes a very simple experiment which you can do by reserving one of these subnets.

These subnets aren't provided by an aggregate, and thus can't be reserved via the GENI AM API. To reserve one for your experiment, contact, and let us know when you'd like to start using the subnet (if not "immediately"), and when you expect to be done with it (if you're not sure, give us a date after which we should check back with you to see if you're done).

Please DO NOT use an IP subnet that you haven't reserved. Thanks!

Current reservations

These sections describe the subnets that are currently reserved. -

This range of addresses is reserved for VLAN-based connectivity testing (e.g. connectivity test subnets).

The subnets of are typically used by MyPLC plnodes on an alias subinterface of a VLAN-based sub-interface, e.g. eth1.1750:42101 for on VLAN 1750. They could theoretically be put on other interfaces, but given the large size of the space, we'd prefer to use them only in this fashion.

WiMax dataplane

These subnets are reserved for the WiMax dataplane connections. See the Orbit lab wiki for the authoritative listing for this address range.

The subnets of outside of the WiMax range are typically used by MyPLC plnodes in some other (probably unusual) fashion. ("They're like .42, but odd.") Because each one might be different from all the others, we haven't pre-provisioned any that aren't currently in use, so if you'd like one, just contact, and we can help figure out the best way to set it up.

Subnet Reserved by/for Reserved until Aaron Rosen for his research 2011-11-28

This subnet is reserved by the GPO as a connectivity test subnet for regionals and campuses connected to the GENI network core.

This subnet is reserved by the GPO for testing OpenFlow datapath health monitoring.

This subnet is reserved by Nick Bastin for testing Virtual Dynamic Datapaths.

This subnet is reserved by the GPO for FOAM testing.

IP addresses

Within the subnets above, we've allocated IP addresses to various mesoscale nodes, giving each a consistent fourth octet across the subnets (e.g. is,, etc).

The MyPLC plnodes are pre-configured to use these, and MyPLC doesn't allow experimenters to change that configuration.

The ProtoGENI pgnodes and wapgnodes are not preconfigured to use these, since experimenters control those configurations. You can also use addresses other than the ones below for pgnodes and wapgnodes if you want, as long as you don't use an address that's live on a plnode.

Here are the addresses:
