Topology Reservation

reserve.py takes a number of arguments, most of which are optional.

--site	Site to deploy topology, as a site name (vts-gpo, etc.)
--slice	Slice name
--project	Project name (typically the geni-lib default)
--with-nf	Build with network function – don’t set to get baseline
--context-path	Path to context JSON, if not default location
--delete	Delete any pre-existing sliver with same slice name
--num-sites	Number of sites to deploy in topology
--num-sensors	Number of sensors to deploy per site
--mgmt-loss	Percentage of loss in network
--mgmt-delay	Delay in ms between every site and mgmt location
--mgmt-reorder	Percent of packets to reorder
--config-path	SSH Config file location for constructed topology
--uhexp-url	URL for uhexp repository
--uhexp-branch	Branch in supplied repository
--nf-url	URL for doe-nf repository
--nf-branch	Branch in supplied repository
--nfbase-url	URL for pynf-base repository
--nfbase-branch	Branch in supplied repository

Only slice is a required argument if you have a properly set up geni-lib context. You can use the URLs and branches to supply your own modification to the experiment. The default values of num-sites is 2 and num-sensors is 3, which you will need to know to provide input to runexp.py. You will have to set reorder and delay parameters in order to get useful results, but they are not required for basic packet delivery to function.

The common execution of reserve.py for an NF deployment will simply be:

$ reserve.py --with-nf --mgmt-delay 1000 --mgmt-reorder 20 --slice slicename
