This strategy works by opening multiple network connections to distribute the traffics equally but we have to mention that this can be accomplished as long as the data links in the subnet are able to handle the capacity. 7. Suppose we design a reliable transport protocol that use only NAKs as feedback from receiver to sender: • If the data rate is low (sender sends packets infrequently), is a NAK-only protocol better than an ACK-based protocol? Why? o In this case a NAK-only protocol will not be better because such protocol only detects lost of packet when a following packet is correctly received, consequently this can represent long error recovery time. • if the data rate is high and the network drops only a small number of packets is a NAK-only protocol better than a ACK-based protocol? Why? o When the rate is high an ACK-based protocol is not appropriate because of the high overhead. If data rate is high NAK’s are sent occasionally oppose to ACKs never sent representing a significant reduction of feedback. So recovery under NAK could be faster. 8. What are the 3 transport layer services? These services…
