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.
