1. Seamless On-The-Fly Compression with OpenFlow By Benjamin Ujcich and Derek O'Neill

2. Goals Reduce bandwidth usage on link Files leave source and arrive at destination decompressed No configuration by users

3. Resources Source node on GPO (bain) Destination node on Clemson (planetlab4)  OpenFlow controller Agent on GPO (pc5) Connecting OpenFlow resources

4. Strategy Traffic sent from source to destination is redirected to agent via OpenFlow, compressed, and sent to destination with headers rewritten Agent at destination network intercepts packets via OpenFlow, decompresses, and sends to destination with headers rewritten

5. Results

7. Concerns Moving Forward Only one agent, no decompression Added latency Instability due to volatile FlowMods Packet-based vs. File-based
