Consider a multicomputer in which the network interface is in user mode, so only three copies are needed from source RAM to destination RAM.

Assume that moving a 32-bit word to or from the network interface board takes 20 nsec and that the network itself operates at 1 Gbps. What would the delay be for a 64-byte packet being sent from source to destination if we could ignore the copying time?

What is it with the copying time?

Now consider the case where two extra copies are needed, to the kernel on the sending side and from the kernel on the receiving side.

What is the delay in this case?
