Please give one example protocol with handshaking at the application layer and one example protocol without handshaking at the application layer.

PIO. Consider a short, 10-meter link, over which a sender can transmit at a rate of 150 bits/sec in both directions. Suppose that packets containing data are CHAPTER 2 . APPLICATION LAYER 100,000 bits long, and packets containing only control (e.g., ACK or hand- shaking) are 200 bits long. Assume that I parallel connections each get 1/N of the link bandwidth. Now consider the HTTP protocol, and suppose that each downloaded object is 100 Kbits long, and that the initial downloaded object contains 10 referenced objects from the same sender. Would parallel downloads via parallel instances of non-persistent HTTP make sense in this case? Now consider persistent HTTP. Do you expect significant gains over the non-persistent case?
