1. A UDP segment is sent from port 4096 on host 10.0.0.1 to port 8192 on host 10.0.0.2. The application data field is three 32-bit word that consist of the repeated octet 10101010. What is the size, in bytes, of the UDP segment?

2. Consider a 2000-km link with a rate of 40 x 10⁶ bps in both directions and a propagation velocity of 2 x 10⁵ km/s, over which the HTTP protocol is used. Suppose that the initial downloaded object contains 20 referenced objects from the same server and that each of the 21 objects is 5,000 bytes in length. Packets that contain control information only are negligibly small. Ignoring any DNS lookup time,

(a) compute the Page Load Time (PLT). Assume non-persistent HTTP with no parallel connections and no pipelining.

(b) compute the Page Load Time (PLT). Assume persistent HTTP with no parallel connections and no pipelining.
