The paper outlines how Kurose and Ross discuss the transport layer, and asserts that the authors give a good explanation of the relationship between the transport layer and the application and network layers, providing the reader with a basic understanding of network architecture. The paper looks at how they discuss reliability and whether it is possible to consider networks reliable when data corruption and loss is possible, and how they address congestion. The paper posits that while congestion-related delays and data loss are a risk of today's modern Internet, James and Ross seem overly pessimistic about future reliability.
From the Paper:"Understanding networks can be easy, because one can draw a physical representation of a network. Likewise, understanding applications seems simple, because most people use applications repeatedly as part of their daily lives. However, understanding the transport layer is more complex. Transport layers convert information from application processes into transport-layer packets or segments (James and Ross, p.198). "The transport layer then passes the segment to the network layer at the sending end sys-tem, where the segment is encapsulated within a network- layer packet ( a datagram) and sent to the destination" (James and Ross, p.198). The network layer extracts the transport layer from the datagram and passes the segment to the transport layer, which processes the received data" and makes it available to the application level (James and Ross, p.198). What is even more interesting is that transport layers can add dimensions beyond merely transporting data. For example, the use of a reliable transport system can help address reliability issues within a network (James and Ross, p.201). Networks operate via Internet Protocol (IP), which is a best-effort delivery service without any guarantees for data transmission or the integrity of data that has been transmitted (James and Ross, p.202)."
