The Open Systems Interconnection (OSI) Layer 3 (Network Layer)
is one of the layers that performs packet segmentation.
The OSI Layer 3 is roughly equivalent to the Internet
Layer of the Transmission Control Protocol/Internet
Protocol (TCP/IP) model, and 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) and 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 above questions to write your paper of 4–5
