NAME

rocketfuel-to-ns

SYNOPSIS

rocketfuel-to-ns --rf-dir=dir

DESCRIPTION

Take RocketFuel topologies and convert them into a set of configuration files appropriate for use on the Deterlab testbed.

OUTPUT

The output of this script includes:

out.ns: the NS configuration file, to be uploaded to DETER

: setup-ospf.pl: to be run on each node allocated by the testbed; sets up OSPF
: setup-bgp.pl: similar to above, except sets up BGP
: setup.sh: main setup script

In addition, the module "ip2device.pm" should be placed in such a manner as to be accessible by the setup-* scripts above.

MECHANICS

When the script is first invoked, it reads the entire contents of the data directory provided. After this, a breadth first search is performed on the graph. The exploration proceeds under options specified below, until one of the criteria is not satisfied, or the entire graph is explored.

OPTIONS

--rf-dir=dir

Set the path to the RocketFuel data files. Defaults to "./maps-n-paths"

--max-nodes=N

Limit the output to N nodes.

--max-degree=N

Limit the output such that no node has degree greater than N; an arbitrary subset, not to exceed N, of edges for large degree nodes will be chosen.

--want-asns=ASN1,ASN2,..

When choosing a topology, select nodes from ASN1, followed by ASN2, so on and so forth. ASNs not specified in the list are ignored.

--multiplex-thres=N

After a given node's degree reaches N, annotate further edges using the tb-set-multiplexed flag. This enables link virtualization for those links.

--path-to-bgpdconf=S

On the testbed nodes, specify the path to the BGP configuration file (bgpd.conf). Defaults to /usr/local/etc/bgpd.conf

--path-to-ospfdconf=S

On the testbed nodes, specify the path to the BGP configuration file (ospfd.conf). Defaults to /usr/local/etc/ospfd.conf

--start-node=S

Specify the start node for the BFS search. A random node will be selected if (a) the node does not exist or (b) this option is not specified. If used in conjunction with the want-asns option, a random node from one of those listed will be preferred.

--path-to-setup=S

Specify the remote directory that will contain the setup scripts. Setup scripts are generated by rocketfuel-to-ns and need to be copied to this directory after the experiment is created.
