Waffle

NOTE: Although Waffle is intended & recommended to run on 3 different machines, we can still run all the three processes on the same machine.

Waffle is the first system to hide data access patterns adaptively, without requiring to known the input data access distribution, under a passive persistent adversary. Waffle incurs a constant bandwidth and client-side storage overhead, both of which can be configured by an application owner.

Requirements

• cmake-3.5+
• redis-server (https://redis.io/docs/getting-started/installation/install-redis-on-linux/ )

Building

After installing the requirements, run

sh build.sh

inside waffleClient folder

Running

Running Waffle requires atleast 3 machines:

1. Client with a CLIENT_IP and CLIENT_PORT
2. Proxy with a PROXY_IP
3. Redis backing storage server with STORAGE_SERVER_IP and STORAGE_PORT

First start the storage server

Then start the proxy:

./bin/proxy_server  -l <WORKLOAD_FILE> -b <BATCH_SIZE> -r <SYSTEM_PARAMETER> -f <FAKE_QUERIES_FOR_DUMMY_OBJECTS> -d <NUMBER_OF_DUMMY_OBJECTS> -c <CACHE_SIZE> -n <NUM_CORES> -h <STORAGE_SERVER_IP> -p <STORAGE_PORT>

(Example: ./bin/proxy_server  -l tracefiles/proxy_server_command_line_input.txt -b 1200 -r 800 -f 100 -d 100000 -c 2 -n 1 -h 192.168.252.110 -p 6379 )

Waffle will now initialize. After the proxy says it's reachable launch the benchmark code:

./bin/proxy_benchmark -t <TRACE_FILE> -h <PROXY_IP> -p <PROXY_PORT> -n <NUM_CLIENTS>

(Example: ./bin/proxy_benchmark -t tracefiles/proxy_benchmark_command_line_input.txt -h 192.168.252.109 -p 9090 )

After completion the benchmark will display the throughput during the run. There will be a new folder in the data folder that contains one file for each client displaying the latency of each operation in nanoseconds.

Note that although it is expected that each of these processes run on different machine, they can all be run on a single machine on different ports using the localhost ip.
