An organization has a number of tools available when determining how best to address performance issues on their network. The organization can use subnetting or they can use segmentation.

ï‚·
Discuss the pros and cons of each.

ï‚·
Provide examples of when each would be appropriate.

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.

ï‚·
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.

ï‚·
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.

ï‚·
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.

ï‚·
Do you think that most network administrators understand and use both distance-vector and link-state protocols? Why?

ï‚·
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.

For assistance with your assignment, please use your text, Web resources, and all course materials.
