How can I verify that a TCP packet has received an ACK in JAVA? -


after sending tcp data method (mine below)

dataoutputstream outtoserver = new dataoutputstream(clientsocket.getoutputstream()); outtoserver.writebytes(string);

if need know whether data has made other end, need implement acks @ application protocol, not @ transport level tcp concerns with.
