1. (10%) As shown in the above figure, set up a 2-port Linux PC Router first and then install Linux
open source VoIP (Asterisk) and video streaming server (Darwin) on PC1 and PC2. Use
microphones and MPEG-4 clips to examine whether you have installed Asterisk and Darwin
successfully.
<Note>: you need two Ethernet cards and two crossover UTP cables to form a router network.
2. (40%) Write down P2P client/server programs by using TCP socket. Your P2P client/server
programs must work with Asterisk and Darwin and it must allow two users to send and receive
English/Chinese text messages to each other.
3. (50%) Performance measurements:
<NOTE> Three streams (Asterisk, Darwin, and P2P) must be transmitted simultaneously.
I. On Linux router:
(1) (20%) Write down a backdoor program on router to measure the average packet
forwarding delay for Darwin video streaming. The packet forwarding delay is defined from
the time when sk_buff is constructed for the packet till the time when the packet is
removed from sk_buff.
II. On PC-1/PC-2:.
(2) (20%) Write down a backdoor program on PC-1/PC-2 to measure jitter and average
throughput for Asterisk and Darwin, respectively. Compare their differences.
(3) (10%) Intercept only P2P and count how many IP packets are generated for different
sized of text messages (e.g., 10, 50, 100 English/Chinese words).
