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?
What is byte?
The byte is a digital data unit consisting of eight bits.The byte was historically the number of bits used to encode a single character of text in a computer, and it is thus the smallest addressable unit of memory in many computer architectures.
By using a network time of 1nsec per bit or a time delay of 512nsec per packet.
If network operates itself in 1gbps means the network delivers 125 MB/sec
To copy 64bytes 4 bytes at a time, 320 nsec are needed on each side, or 640 nsec total(source +destination)
Adding the 512-nsec wire time, we get 1132 nsec total. We get 1792 nsec if we need two more copies.
Relocating 64 bytes in 1792 nsec is equivalent to 35.7 MB/sec.
