Practical Network-Wide Configuration Synthesis with Autocompletion

Install

1. Install Z3 from master, see https://github.com/Z3Prover/z3

2. Install network graph library dependency first

pip install -e git+git@github.com:nsg-ethz/tekton.git#egg=Tekton
# Or from a local clone
pip install -e .

3. Install python dependencies

pip install -r requirements.txt

An Example use of NetComplete

The example at synet/examples/bgp_peers.py shows how to use NetComplete to synthesize Provider/Customer peering policies.

Running

python synet/examples/bgp_peers.py outdir

Running NSDI Experiements

Running BGP experiements

# BGP
 ./eval_scripts/run-ebgp-experiments.sh
# OSPF
 ./eval_scripts/run-ospf-experiments.sh

Running OSPF

python synet/drivers/ospf_driver.py --help

Example

python synet/drivers/ospf_driver.py  -p [NUMBER OF PATHs generated per iteration] -r [NUMBER OF REQS] -f [TOPO FILE NAME.graphml]

python synet/drivers/ospf_driver.py -r 20 -p 100 -f topos/topozoo/AttMpls.graphml

Running Tests

Commonly used nosetests options:

• Timing each test case: --with-timer
• Running specific tests with tags -a tag=value
• Running specific test case nosetests FILE_PATH:TESTCLASS or nosetests FILE_PATH:TESTCLASS.TESTCASE

Running fast tests: nosetests --with-timer -a speed=fast test/

Running slow tests: nosetests --with-timer -a speed=slow test/

Running all tests (fast and slow) nosetests --with-timer test
