Response time under packet loss

I am experiencing a problem where under a dial condition I am experiencing packet loss, which is failrly normal, but the response to the packet loss is taking bewteen 6 and 10 seconds. Could someone please advise what the industry standard is on the response time under a packet loss senario.

It depends.

There is an industry standard algorithm for TCP packet retranmission. But it must adapt to the measured round trip time for the connection. UDP will not attempt to detect or retransmit datagrams. If a packet is lost for a UDP program, the program itself must detect this and decide what to do.
