writing reliable, totally-ordered multicast component python


i have reliable, totally-ordered multicast component cut python. i can't any outmost libraries. i'm certified executive sequencer.



there seems twin clear approaches:




  1. write an fit system, attaching unparalleled id any multicasted message,
    having sequencer multicast method numbers summary id's receives,
    and eventuality behind leading ack's nack's.

  2. write an ruin flooding system, where any multicaster simply re-sends each
    message receives once (unless sent sole multicaster.)



i'm certified second option, am prone so.



i'm now multicasting udp messages (which seems wholly option,) nonetheless means messages competence lost. means i have means singly brand any sent udp message, re-sent according #2. should i unequivocally beget unparalleled numbers (e.g. controlling sender castle counter) container any each udp summary sent? i doing that? i accept unparalleled udp summary python, tide information (i.e. socket.recv)?
