Imagine you are the network administrator of University X having 10 campuses in Towson, Maryland. You want to build a connected network of servers (each server is either a regular or a routing one), one at each campus, and want to choose some of them to be the designated routing servers. A routing server will serve regular servers who connect directly to it via high speed cables, and every regular server must connect to at least one routing server. Your goal is to minimize the total length of high speed cable that you must purchase. Given the locations of the 10 campuses, design a plan that requires (1) the shortest length of cable and (2) the least number of routing servers.
ii) Describe the four abstraction levels of TCP and IP.ii) Describe a hypothetical circumstance in which two different computer computers are collaborating to share a video file by means of an unsecured ftp connection with a potentially insecure TCP three-way handshake.
What is the difference between subnetting and a subnet mask?
Which address on a personal computer (PC) does not change, even if the PC is moved to a different network? Justify your answer. Your answer: 2. Which OSI model layer manages communications in simplex, half-duplex, and full-duplex modes? Your answer: 3.How does the OSI reference model guarantee independence of layer functionality?
The benefits and drawbacks of connectionless vs connection-based protocols should be compared and contrasted.

5. The following is one possible layered architecture. State which layer(s) is/are "allowed to use" which layer. A B1 B2 вз
Consider each tier of the TCP/IP protocol stack and assign a priority to each layer based on your assessment of their importance. Is it possible to merge or separate any of these layers? Would the kind of data sent alter your ordering, and if so, how? Justify your ordering decision. Utilize the scale below: 1 represents the most critical factor, while 5 represents the least critical factor.
The goal of this assignment is to explore the network packets associated with several typical online activities. You will have the chance to analyze bit-by-bit the flows associated with these services and evaluate different application and protocol parameters across the entire TCP/IP stack including Data Link Layer/Medium Access Control (L2), Network Layer (a.k.a. IP or L3), Transport Layer and Application Layer. To carry out this analysis, you will use Wireshark. Part of finishing this assignment will be learning how to use Wireshark effectively. While Wireshark allows you to capture packets on a network interface it can also be used to read previously collected packet traces. Make sure to show the full steps and screenshots of capturing network packets on Wireshark.

a) Explain how OSPF routing becomes more scalable in a large network by partitioning it in areas and a backbone area. What is the drawback of breaking a network in smaller areas compared to running OSPF in the original network? b) What is the role of the sequence number in the OSPF LSP?
