For this week in my computer networking course, we explored the transport layer and its protocols, UDP and TCP. UDP operates without establishing a connection, allowing independent handling of its segments. It lacks reliability, as lost or out-of-order segments are not resent or acknowledged. On the other hand, TCP ensures reliable data transfer through sequences and acknowledgments. It also incorporates congestion control mechanisms to manage network congestion. We discussed various concepts, such as multiplexing, demultiplexing, and the implications of pipelining on reliable data transfer protocols. Additionally, we also we delved into calculations like EstimateRTT, DeviationRTT, and Timeout-interval, applying them in assignments, labs, and problem sets.
