Unformatted text preview: Node 2 choose the same value is: P 1,2 = 2 c1 / (2 c1 x 2 c2 ) = 1/2 c2 Similarly, P 1,3 = 2 c1 / (2 c1 x 2 c3 ) = 1/2 c3 And P 2,3 = 2 c2 / (2 c2 x 2 c3 ) = 1/2 c3 So, the probability that a collision occurs next is: P 1,2 + P 1,3 + P 2,3 = 1/2 c2 + 1/2 c3 + 1/2 c3 = 1/2 c2 + 2/2 c3 Quiz #7 Question: How many different multicast IP addresses at most can share the same MAC address? Answer: 2 5 = 32 . Because of the five bits in pink in slide 64 (of Chapter 5) about Mapping of Multicast IP Addresses to IEEE 802 Multicast MAC Addresses Quiz #8 Plain text = 010 110 001 111 Ciphertext = 101 000 111 001...
