Consider a home network connected to the Internet through a single home router that supports the Network Address Translation (NAT) protocol. The ISP is only providing a single public IP address to the owner of this network (82.7.30.73). Let us assume that one of the connected home devices with IP address 192.168.0.1 has an open connection from source port 30000 to a web server with IP address 172.217.169.4. The source IP and port of the incoming TCP segments that the web server sees could be: 192.168.0.1, 30000 82.7.30.73, 5555 192.168.0.1, 5555 172.217.169.4, 80

a. Suppose we send into the Internet two IP datagrams, each carrying a different UDP segment. The first datagram has source IP address A1, destination IP address B, source port P1, and destination port T. The second datagram has source IP address A2, destination IP address B, source port P2, and destination port T. Suppose that A1 is different from A2 and that P1 is different from P2. Assuming that both datagrams reach their final destination, will the two UDP datagrams be received by the same socket? Why or why not? b. Suppose Alice, Bob, and Claire want to have an audio conference call using SIP and RTP. For Alice to send and receive RTP packets to and from Bob and Claire, is only one UDP socket sufficient (in addition to the socket needed for the SIP messages)? If yes, then how does Alice's SIP client distinguish between the RTP packets received from Bob and Claire?
Given the following topology of a network, the router Node 3 connects the two subnets together: Nodes 1 and 2 are 'inside' of the subnet neta, Nodes 4 and 5 are 'outside' of neta and Node 3 with a firewall is the gateway of neta. The two networks have the prefix 192.168 as the first two octets in their IP addresses, e.g, Node 1 has IP address 192.168.1.11. eth1: 1.11 eth1: 2.21 1 2 eth1: 1.12 neta eth 1: 1.1 3 eth2: 2.1 netb 4 5 eth1: 2.22 (i) Suppose in the firewall on Node 3 the default policy is ACCEPT. Write packet filtering rules for the following goal. Suppose Node 5 hosts a web server supporting both HTTP and HTTPs. Set rules in Node 3 that prevents Node 2 from browsing any web pages at Node 5. Now change in Node3 the default policy as DROP and write packet filtering rules for the following goal. (ii) Allow all nodes in the subnet neta to browsing HTTP pages hosted at Node 5. (iii) Allow hosts in netb to SSH into Nodel.
In IPV4, consider sending a 4,000 byte datagram (20 bytes of IP header) into a link that has an MTU of 1,500 bytes. The datagram will be allocated to fragments, and the offset value of the third segment is 3, 370 3, 185 4, 185 4, 370
Assume that there are four routers (R1, R2, R3, and R4) and four hosts (H1, H2, H3, and H4) in a network (N1). H1 sends an email to an instructor H3 at SEU.EDU.SA. (192.168.1.1) and the router path is R1, R3, R2, and R4, but the H3 host find a parameter problem and dropped the packet. Explain how ICMP protocol can be used as a debugging tool and draw a diagram to illustrates the traceroute process for this scenario? PART 2 || Characteristics The Transport-layer Protocol It is a simple connectionless protocol with neither flow nor error control. The size of the send window must be less than 2m; the size of the receive window is always 1. Each time a single packet is lost or corrupted, the sender resends all outstanding packets, even though some of these packets may have been received safe and sound but out of order. Both the sender and the receiver use a sliding window of size 1. The sender sends one packet at a time and waits for an acknowledgment…

Assume the maximum transmission unit (or MTU) of an IP packet on 100 Mbps Ethernet is set at 1500 bytes. Also, assume we are sending our file using IPv6 at the Network layer and UDP at the Transport layer. A typical IPv6 header consists of 40 bytes, a UDP header consists of 8 bytes. Answer the following three questions based on the information provided above. For all answers, enter a decimal integer value without formatting (no commas). 1. How many packets do we have to send in order to transfer a file of 24KB over 100 Mbps Ethernet? packets 2. How many bytes do we have to send at the network layer in order to transfer the above file entirely? bytes 3. How many bytes do we have to send at the data link layer in order to transfer the above file entirely? Assume that the Ethernet header is 14 bytes and the frame checksum is 4 bytes. bytes
The maximum packet size (Maximum Transmission Unit or MTU) of an IP packet including IPv4 header on 100 Mbps Ethernet is usually set at 1500 bytes. A typical IPv4 header consists of 20 bytes, and a UDP header consists of 8 bytes. If we split up a file of 20,000,000 bytes so we can send it as a series of UDP payloads, how many IP packets do we have to send in order to transfer the entire file? Enter an integer number without formatting (no commas). Answer:
