5. [reliability] [stop-and-wait] [pipelining/sliding window] consider a link with speed 100mbps, one way propagation delay 10 msec, and packet size 1,000 bits. a. what is the goodput achieved if the alternating bit (also known as stop and wait) protocol is used over this link? you can count the packet header as part of the goodput. b. how large does the window size need to be for a pipelining reliability protocol to make maximum use of the link?
