Method Detail

retransmit

void retransmit(long first_seqno,
                long last_seqno,
                Address sender)

Get the missing messages between sequence numbers first_seqno and last_seqno. This can either be done by sending a retransmit message to destination sender (nak-based scheme), or by retransmitting the missing message(s) to sender (ack-based scheme).

Parameters:

first_seqno - The sequence number of the first missing message

last_seqno - The sequence number of the last missing message

sender - The destination of the member to which the retransmit request will be sent (nak-based scheme), or to which the message will be retransmitted (ack-based scheme).
