HOWTO

Setup desvirt

Run ./setup.py build install to build and install desvirt on your machine.

In case you want to use desvirt with RIOT nodes: ./topology_creator --node-type riot_native --binary-file ../projects/ccn-lite-client/bin/ccn-lite-client.elf --size 9

Create topology

To create a topology run ./topology_creator which creates a 2x2 grid w/o loss .desvirt/grid2x2.xml (default).

./topology_creator -h
Usage: topology_creator [options]

Options:
  -h, --help            show this help message and exit
  -s TOPO_SIZE, --size=TOPO_SIZE
                        the size of the network
  -t TOPO_TYPE, --type=TOPO_TYPE
                        select type of topology
  -f XMLFILENAME, --file=XMLFILENAME
                        write xml output to FILE
  -d DESCRIPTION, --description=DESCRIPTION
                        a short description of the network
  -l DEF_LOSS_RATE, --loss-rate=DEF_LOSS_RATE
                        set the (default) loss rate for a unicast link in
                        percent
  -g HIGH_LOSS_RATE, --high-loss-rate=HIGH_LOSS_RATE
                        set the loss rate for a diagonal unicast link (only
                        meaningfull for grid topologies) in percent
  -b BCAST_LOSS_RATE, --bcast-loss-rate=BCAST_LOSS_RATE
                        set the loss rate for a broadcast link in percent
  -n NODE_DESC, --node-type=NODE_DESC
                        defines the node type (meshrouter or riot_native)
  -r RADIO_NIC, --radio-interface=RADIO_NIC
                        the name and type of the radio interface (wlan or
                        ieee802154)
  -e BINARY, --binary-file=BINARY
                        the binary file for RIOT native

Setup topology

./vnet --define --name "grid3x3"

To run a topology run ./vnet --start --name "grid3x3" which starts the grid.

./vnet -h
Usage: vnet [options]

Options:
  -h, --help            show this help message and exit
  -d, --define          set up persistent configuration
  -s, --start           set up virtual network, start all virtual machines
  -q, --stop            stop virtual network, shut down all virtual machines
  -u, --undefine        remove persistent configuration
  -n TOPOLOGY_NAME, --name=TOPOLOGY_NAME
  -l, --list-defined    list all defined networks
  -v, --verbose         increase verbosity
