Chapter 3 Review Questions 1. a) Call this protocol Simple Transport Protocol (STP). At the sender side, STP accepts from the sending process a chunk of data not exceeding 1196 bytes, a destination host address, and a destination port number. STP adds a four-byte header to each chunk

thus be big enough to accommodate 2w sequence numbers. That is, the sequence number space must be at least twice as large as the window size, wk 2t . Problem 24 a) True. Suppose the sender has a window size of 3 and sends packets 1, 2, 3 at 0t. At

Chapter 4 Review Questions 1. A network-layer packet is a datagram. A router forwards a packet based on the packets IP (layer 3) address. A link-layer switch forwards a packet based on the packets MAC (layer 2) address. packets IP (layer 3) address. A link-layer switch forwards

Chapter 6 Review Questions 1. In infrastructure mode of operation, each wireless host is connected to the larger network via a base station (access point). If not operating in infrastructure mode, a network operates in ad-hoc mode. In ad-hoc mode, wireless hosts have no infrastructure with which to

Chapter 8 Review Questions 1. Confidentiality is the property that the original plaintext message can not be determined by an attacker who intercepts the ciphertext-encryption of the original plaintext message. Message integrity is the property that the receiver can detect whether the message sent (whether encrypted or not) was

These two messages concern themselves with the Diffie-Hellman key exchange. Each host independently computes and exponent and a nonce which is then sent to the other host. This is done one after the other in messages 3 and 4. Once both the hosts have these

IPSEC LAB Part 1:IPSec connection with Manual Keying in the same subnet (Transport mode) The goal of this part of the lab is to establish an IPSec connection between M1(192.168.100.2) and M3 (192.168.101.2) within the same (inner) subnet. The topology of the network is shown
