I wrote new failure detection algorithm based on heartbeat signal for ng_one2many node. Features: - automatic detection of failures; - all subnet containing failed element marked as failed. Therefore packets sended from other hosts to host, holding failed element, wouldn't lost; - automatic detection of recoveries; - detection of point of failure (see diagnostics in man page); - configurable timing parameters of failure and recovery detection; - you can create your own heartbeat packet or use default; - you can set your rules for detecting that incoming packet is hearbeat packet; - heartbeat algorithm can be used for different network layers (not only ethernet layer). Patches for src and man page at http://www.watson.org/~ilmar/download/ng_one2many.tgz These patches for CURRENT, but you can compile patched files in 5.3.
