The Open Systems Interconnection (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 Transmission Control Protocol/Internet Protocol (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.

Describe in detail how packets are segmented by the Host-to-host layer (Transport Layer) Internet Layer of the TCP/IP model.

• Do all packets arrive at their destination in the order in which they were segmented and transmitted? Why or why not?
• Describe how segmented packets are rearranged or reassembled at the packets' destination to ensure that received segmented packets match the order in which they were segmented and transmitted.
• How are errors handled during transmission of segmented packets?
• What is the difference between a TCP segment and an IP packet?

Please answer the following questions and requirements to write your paper of 4-5 pages.

(Part B Short Answer discussion)

An organization has a number of tools available when determining how best to address performance issues on its network. The organization can use subnetting, or it can use segmentation. Discuss the following:

• Discuss the pros and cons of each.
• Provide examples of when each would be appropriate.
