I need help creating a thesis and an outline on User-Level Packet Capture. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. Principal differentiation among the two is that whereas intermediate routers can fragment a unit datagram or fragment further a datagram that is a fragment already, intermediate devices do not perform reassembly. This can be accomplished only by the critical target of the IP message. An intermediate router on one side of a physical network of a datagram with an MTU of 1,300, if it fragments 3,300-byte datagram, the router on the other end of 1,300 MTU link will not return the 3,000-byte datagram to its initial state. It will mail all the 1,300-byte fragments down on the internet.

Wright and Stephens (1995) argue that the decision to implement IP reassembly this way is carried out to avoid certain problems. First, fragments can acquire diverse routes to obtain, from the source to target so any given router may not see a message in all the fragments. Secondly, having routers need to concern about reassembling fragments would increase their difficulty. Last, message reassembly requires that all fragments are waited for before sending on the message reassembled. Allowing routers to perform this would slow routing down. Since routers do not reassemble, they can forward immediately all fragments on to the ultimate recipient.

Some of the drawbacks include according to Henderson (2009) are: First, it results in smaller fragments traveling longer routes than if intermediate reassembly occurred. This increases the likelihood of a fragment getting lost and thus discarding the entire message. Secondly, there is a probable inefficiency in the data utilization of link-layer frame capacity. For example, the 3,300-byte datagram at the end of the 1,000-MTU link would not be reassembled back by 1,300-byte fragments. If the link after that one also had an MTU of 3, 300, and then it would have to be sent in frames of three, every encapsulating a 1,300-byte fragment, instead of a larger single frame.
