PeerSim vs NeuroGrid: Statistics

According to this HOWTO, PeerSim generates the following statistics about query packets:

  • queryID
  • message TTL
  • number of times the packets has been seen
  • number of successful packet hits
  • total number of messages sent for this query

The NeuroGrid advanced simulation produces the following log files containing statistics:
  • MAIN_LOG_FILE - loop, No matches, TTL, message transfers, Nodes reached, possible matches
  • SUMMARY_LOG_FILE - loop, No matches (ave,stdev), TTL (ave,stdev), message transfers (ave,stdev), Nodes reached (ave,stdev), proportion matches (ave,stdev), efficiency (ave,stdev)
  • ARCHITECTURE_LOG_FILE - loop, total nodes, total conns, total knowledge, total knowledge links, message transfers
  • PROBE_LOG_FILE - loop, total nodes, ttl (ave,stdev,max,min)
