End-to-end latency of Addax's interactive auction protocol

How to build

cmake . -B build
cd build
make -j

How to run

  1. Start publisher.
    • Run ./publisher-interactive -a AD_NUM -r ROUND
  2. Start bidders.
    • On each machine of the bidders, run bash simulate-advs-interactive.sh BIDDER_NUM STARTING_PORT BUCKET_NUM PUBLISHER_IP:6668 IDX-OF-STARTING-ADVERTISER ROUND.
      • The script will launch BIDDER_NUM bidders on that machine. These bidders' ports start from STARTING_PORT to STARTING_PORT+BIDDER_NUM-1, each bidder instance listens on one port.
    • If you want to run the bidder programs on different machines, then you can run the script on each machine individually.
      • IDX-OF-STARTING-ADVERTISER is set to 0 when you run the script on the first machine (or if you are only using a single machine). After running the script on the first machine, IDX-OF-STARTING-ADVERTISER should be set to the total number of bidders you have launched.
        • For exmaple, if you have started 48 bidders on the first machine, when you launch another 48 bidders on the second machine, IDX-OF-STARTING-ADVERTISER should be set to 48. And when you launch another 48 bidders on the third machie, IDX-OF-STARTING-ADVERTISER should be set to 96 (48 on the first machine and 48 on the second machine).
  3. Start another auction server.
    • Create a file (FILENAME-OF-ADVS-IP in the parameter when running server-interactive) where each row consists of one bidder's ip address in the format of IP:PORT.
    • Run ./server-interactive -a AD_NUM -p PUBLISHER-IP -r ROUND -f FILENAME-OF-ADVS-IP.
    • The last output of server-interactive is the total end-to-end latency.
  4. After each run, you need to manually kill all advertiser progesses, by running pkill -f -9 advertiser-interactive.

Note

  • If not specified, the unit of outputs related to time is second and the unit for size of materials is byte.
  • By default the program is running second-price auction. If you want to test the end-to-end latency of first-price auction, add -q to when running publisher-interactive and server-interactive.
