Description / paper instructions
IP Fragmentation is a major issue.
Consider delivering an 8000-byte datagram over a network with a 1000-byte MTU.
a) What is the total number of fragments produced?
b) What are their characteristics (i.e., what flags and offset values do they have for each)? (Assume that the DF flag was not set : )
Assume that the IP header’s optional fields aren’t being used (i.e. IP header is 20 bytes)
c) Where are smaller datagrams reconstructed when a large datagram is split into many smaller datagrams?
d) Describe the operation of traceroute. Include a traceroute to a site that is at least 9 hops away from your current location.
Problem 2: CIDR -A router’s routing table has the following (CIDR) entries:
Gateway to the final destination The following hop is
Interface 0: 197.46.56.0/21
Interface 1: 197.46.60.0/21
196.53.40.0/22 Router 1 is the default route; Router 2 is the alternate route.
1. What does the router do if packets with the following addresses arrive at each of the following IP addresses?
(a) 197.46.63.10/21 (b) 197.46.67.14/21 (c) 135.46.52.2 /22 (d) 196.53.40.7 /24 (e) 196.53.56.7/24 (f) 196.53.56.7/24
2. What is the connection between the fields “gateway” and “interface”?
3rd Layer Network Problem
1. How is an IP address assigned to a host? What method does a network use to obtain the subnet portion of an IP address? How can a provider obtain an IP address block? What is the underlying premise of these procedures?
2. There are five interfaces on a router. What is the number of IP addresses it will have?
3. What problem is Network Address Translation (NAT) designed to solve? Please give a brief description of what NAT performs.
Problem #4: Data Link Layer: Assume that nodes A, B, and C are all connected to the same broadcast LAN (through their adapters). Will C’s adapter process tens of thousands of IP datagrams sent by A, each encapsulating frame sent to B’s MAC address? Will C’s adapter deliver the IP datagrams in these frames to network layer C if this is the case? What if A sends frames with the MAC broadcast address? How would your answers change?
b) What is the size of the MAC address space? What about the IPv4 address space? What about the IPv6 address space?
c) What is the purpose of sending an ARP inquiry in a broadcast frame? When a response is sent within a frame with a specific MAC address as the destination?
d) In CSMA/CD, what is the likelihood that a node chooses K=10 after the sixth collision? If the answer is K=4, how many seconds of delay does this translate to on a 10Mbps Ethernet?
e) Assume you’re moving a PC from one department to another. Is it necessary to alter the physical address? Is it necessary to update the IP address? Is it important whether the computer is a desktop or a laptop?

The answer is complete. |
50 points: The essay illustrates exemplary understanding of the relevant material by thoroughly and correctly addressing the relevant content; identifying and explaining all of the key concepts/ideas; using correct terminology explaining the reasoning behind key points/claims and substantiating, as necessary/useful, points with several accurate and illuminating examples. No aspects of the required answer are missing. |
Use of Sources (worth a maximum of 20% of the total points). |
Zero points: Student failed to include citations and/or references. Or the student failed to submit a final paper. |
5 out 20 points: Sources are seldom cited to support statements and/or format of citations are not recognizable as APA 6th Edition format. There are major errors in the formation of the references and citations. And/or there is a major reliance on highly questionable. The Student fails to provide an adequate synthesis of research collected for the paper. |
10 out 20 points: References to scholarly sources are occasionally given; many statements seem unsubstantiated. Frequent errors in APA 6th Edition format, leaving the reader confused about the source of the information. There are significant errors of the formation in the references and citations. And/or there is a significant use of highly questionable sources. |
15 out 20 points: Credible Scholarly sources are used effectively support claims and are, for the most part, clear and fairly represented. APA 6th Edition is used with only a few minor errors. There are minor errors in reference and/or citations. And/or there is some use of questionable sources. |
20 points: Credible scholarly sources are used to give compelling evidence to support claims and are clearly and fairly represented. APA 6th Edition format is used accurately and consistently. The student uses above the maximum required references in the development of the assignment. |
Grammar (worth maximum of 20% of total points) |
Zero points: Student failed to submit the final paper. |
5 points out of 20: The paper does not communicate ideas/points clearly due to inappropriate use of terminology and vague language; thoughts and sentences are disjointed or incomprehensible; organization lacking; and/or numerous grammatical, spelling/punctuation errors |
