Hi to everybody.
I understand that udpcast guarantees the integrity of the transmitted data
through FEC redundancy code model but how can one be assured , beside
integrity, also of consistency of the transmitted data, defining
consistency as the property the all the hosts being part of the multicast
group have received the data?
I mean, if my multicasting model is composed of N host and I schedule to
send a different file every T minutes, how can I detect the condition of D
hosts not reachable for a time >T (tahr result in data copied only on N-D
Should I check the 'health' of all my N hosts before to run udpcast using
For the application I've in mind it's very important to know what has or
hasn't been delivered to whom so, I would like to encourage everyone who
has had a similar problem or has some idea how to cope with.
Thanks a lot in advance for your suggestions.
