Some of this was discussed elsewhere. There are two cases to look at: 1) Client sends a packet and the server doesn't receive it This is the simple case. If the client doesn't get a response from the server it can reissue the same request and hope that the server gets it the second time. Open issue is how many retries should there be before it gives up? 2) The client sends the packet and the server receives it and responds but the client doesn't get the response. If the client now resends the request, what should the server do? Resend? Ignore? Does it need to remember what it last sent? This is a much harder case to resolve.
