The OSI Layer 3 (Network Layer) is one of the layers that perform packet segmentation. The OSI Layer 3 is roughly equivalent to the Internet Layer of the TCP/IP model and the Layer 4 (Transport Layer) of the OSI model is roughly equivalent to the Host-to-Host layer of the TCP/IP model. The above two layers perform network segmentation. Based on the above information, answer the following questions.
(a) Describe in detail how packets are segmented by the Host-to-host layer (Transport Layer) Internet Layer of the TCP/IP model.
(b) Do all packets arrive at their destination in the order in which they were segmented and transmitted? Why or why not?
(c) Describe how segmented packets are re-arranged or reassembled at the packets’ destination to ensure that received segmented packets match the order in which they were segmented and transmitted.
(d) How are errors handled during transmission of segmented packets?
(e) What's the difference between a TCP segment and a TCP packet?

The following is a case study about a design company.
You are a senior network administrator for a networking solutions firm. Years ago, you installed a small LAN at a design company. It is growing fast and needs your networking solutions firm to upgrade its network. You assigned Liz to the job. That afternoon, while preparing to work on a lab assignment from her class in Cisco routing, Liz mentions that she would use a router to increase the performance of the design company's network because routers are better than bridges. Explain to Liz when and where a router would be the best choice. Under what circumstances would a router not be the best choice? Provide examples to clarify your points.
Another technician, Janis, overhears the discussion as she sits down to examine the lab materials on Liz's desk. Janis thinks the design company should use a bridge to solve the problem. She reminds you that the design company has a relatively small network and that a router would be more equipment than necessary. The design company's network is using nonroutable protocols. What do you tell Janis? Provide examples in your explanation and recommendations.
Luke also takes classes in Cisco routing, and he enjoys the hands-on exercises in his class. As he reviews his notes for that night's class, he is unsure of the concept of routing tables. Explain to Luke what kind of information is kept in a router's routing table and what it is used for. What 2 methods can be used to build these tables? Provide examples in your explanation to clarify and accentuate your explanation.
Be sure to cite all references using APA style.

Networks use different routing protocols to select the best routing path to reach other networks. A distance-vector routing uses a set of protocols (IPX, SPX, IP, or DECnet) and a distance calculation through an outgoing network interface to select the most efficient path to a network destination.
Link-state routing protocols track the connection status and type to each link that comes from a network. The criteria for selection are links with greater hops and faster mediums. Those are considered the most efficient links that will be used by the routing protocols.
Do you think that most network administrators understand and use both distance-vector and link-state protocols? Why?
In your opinion, are there other options that can perform the tasks of these protocols? What is the future for routing through these protocols? Explain.
In your own words, please post a response to the Discussion Board and comment on other postings. You will be graded on the quality of your postings.

This is Mark's first time configuring routers and switches. Mark thought it was simply a matter of installing them, and they would just work. However, now you are reading a manual on configuring routers and switches. The first thing you notice is that you are configuring different elements. For example, in routers, you must configure the router’s hostname and BRI interface. For switches, the configuration must occur on the switch's host name, system name, and switching mode, just to name a few of the configurations. Mark might need some help.
Please post an answer to the following questions. Also, support your answers with academic or real IT examples to accentuate your point. Also, you must provide at least 1 feedback post to one of your classmates.
Do you think that one day, routers and switches will not be needed? Why?
In your opinion, do you think the configuration process of routers and switches can be made easier, especially for nonexperts who want to play around with routers and switches? How? Provide an example if you feel that it can be accomplished. If you do not think it can be accomplished, then provide a reason as to why not.

A company wants to create 4 separate offices across the globe. The managers want to be able to connect these offices over the Internet, and they want to make sure that each network is available to each other. That is, they want the routing information of all 4 networks to be available at each site so that any employee can go to any site and work from it, but they are worried about passing traffic over the Internet and how to monitor the traffic for security and compliance reasons.
Please answer the following questions and requirements to write your 3–5 page paper. As you answer each question, you must provide support or evidence that will enhance and empirically prove your answers. Academic IT articles or real-life IT findings that are not found in journals or other academic sources must be used in supporting your answers. Please use APA style for all cited sources, including your reference page.
Discuss the latest implementations of routing protocols that would be used in the company's wide area network and the Internet.
Where is each protocol used in a wide area network (WAN)? How does each protocol work in a WAN?
How would the routers help in monitoring passing traffic over the networks and Internet under safe and secure conditions? Provide examples of how it would be done and why it would be done in this fashion.
If you were able to recommend another way to build this network from the idea and requirements of the company, what would be your recommendation? Why would you recommend this alternative?

Todd, a junior network administrator, is given the task of providing feedback on routing, specifically the routed, nonroutable and routing protocols. It should also address routing congestion. Todd knows that nonroutable protocols cannot go across local area network (LAN) boundaries and that routed ones can transport data across networks. Todd needs help, however, to make a complete feedback report. .
Do you think the term routing congestion can be replaced by network congestion? Why?
In your opinion, what is the purpose of nonroutable protocols? Is there a legitimate reason for having nonroutable protocols? Do you think they can be replaced and with another type of protocol or innovative system?
Be sure to explain differences between routed, nonroutable and routing protocols. Provide examples.
