Usage:
test_launcher_itg.py [-h] [-l] [-t TOPOLOGY] [-B BANDWIDTH] [-lt] [-ls]
[-d SCENARIOS_DIR] [-H HOSTS] [-dr] [-stp]
[-o LOGS_DIR] [-r REPEAT] [--tool TOOL]
[-T TRAFFIC_TYPE] [--c_min C_MIN] [--c_max C_MAX]
[-g CLIENTS] [-f FLOWS]
Mandatory: [-t TOPOLOGY] [-d SCENARIOS_DIR] [-T TRAFFIC_TYPE] [--c_min C_MIN] [--c_max C_MAX] [-g CLIENTS] [-f FLOWS]
Params:
-h, --help show this help message and exit
-l, --store_logs store logs (default: logs are discarded)
-t TOPOLOGY, --topology TOPOLOGY
name of topology to run
-B BANDWIDTH, --bandwidth BANDWIDTH
Bandwidth of links in Mbit/s (default: 1 Mbit/s)
-lt, --list-topologies
list available topologies
-ls, --list-scenarios
list available scenarios
-d SCENARIOS_DIR, --scenarios-dir SCENARIOS_DIR
directory with scenarios (default: current directory)
-H HOSTS, --hosts HOSTS
Number of hosts in network ('per switch' for uniform
distribution)
-dr, --random-distribution
Random hosts distribution in network (default:
uniform)
-stp, --stp-switch Run with STP switches. Disconnects from controller.
-o LOGS_DIR, --logs-dir LOGS_DIR
directory for storing logs (default: logs/ in scenario
directory). Implies storing logs
-r REPEAT, --repeat REPEAT
number of test case repeats (-1 for infinite).
Warning: Logs will be overridden
--tool TOOL Traffic generation tool: iperf, ditg
-T TRAFFIC_TYPE, --traffic-type TRAFFIC_TYPE
Type of generated traffic
--c_min C_MIN Minimum bitrate of generated traffic ( in Mbit/s )
--c_max C_MAX Maximum bitrate of generated traffic ( in Mbit/s )
-g CLIENTS, --clients CLIENTS
Number of clients generating traffic
-f FLOWS, --flows FLOWS
Number of flows per client
EXAMPLE:
sudo python -t agis -d scenarios -T tcp -H 3 -g 5 -f 3 --c_min 5 --c_max 8
Co powinno być konfigurowalne?
- rozklad hostow: uniform/random
- ilosc hostow per switch
- typ ruchu (tcp/udp/random)
- charakterystyka ruchu (vbr/cbr) ???? // NIEMOŻLIWE W IPERF!
- bitrate (low/medium/high)
- ilość klientów generująca ruch (max=ilość hostów w sieci)
- ilość flowów per klient generujący ruch
- ???

1) Aby zintegrować 'kreator scenariuszy Mininet' z CoSDN proxy należy w /home/user/programs/defnet/other/mn_mods/ podmienić skrypt 'emn.sh' na skrypt znajdujący się z folderze 'emn_script' w tym projekcie.
Zaszły zmiany w sposobie wywoływania aplikacji 'test_launcher.py' - uruchamiany jest teraz w sposób bardziej "generyczny".
EMN parameters:
[topology name]
Format: <zoo-topology-name>-<links_bandwidth>:<host_distribution>-<hosts-per-switch>
[scenario name]
Format: iperf_<traffic_type>-<bitrate_min>:<bitrate_max>-<hosts_generating_traffic>-<flows_per_host>
