Experiment Setup

To enable reproducible results and help in understanding our approach we have open-sourced our full experiment setup including our proof-of-concept implementation of CRDT Web Caching.

The experiment setup can be found [here] or directly via Git:

git clone git@github.com:tumi8/crdt-web-caching.git

The experiment was automated via [pos] framework. If you do not have access to something similar, try the following:

1. set up a fresh debian-bullseye VM or baremetal server
2. clone the repository
3. run the ./setup.sh script (warning: running it on you own PC might install unwanted dependencies, better use a VM). The setup script will install mininet and other dependencies (npm, node, typescript, mininet, etc.)

4. Run the experiment with ./experiment.sh $OUT_DIR $SCENARIO $CACHING_STRATEGY.

   OUT_DIR is the directory where the results are saved
   SCENARIO is either flights or forums (details in the paper)
   CACHING_STRATEGY is on of:

argument	Caching Strategy
crdt	CRDT Web Caching
cache	Invalidation-based Caching
ttl	TTL-based Caching
proxy	No Caching

Note: On our server, the CPULimitedHost feature of mininet did not work and we had to switch to the 2.3.1b4 development branch.
