Class problem

A 4-MByte file is transferred between two computers linked by a router. Each link is 100 Mbps and 100 meters long. Signal propagates at 85% the speed of light. TCP is used for the transfer with MSS=1460 bytes and Receive window is 2048 bytes. How long does it take for the transfer to complete?

Assume only data and TCP headers are transmitted. Assume TCP acknowledgments transmission and queuing delay are negligible. Assume TCP uses delayed acknowledgments. Assume no transmission errors happen and no congestion control is used. Assume TCP connection already established.

No thanks, I prefer to shot myself on the foot than to use OpenOffice.
