This course explores key concepts of packet-switching networks from two perspectives. First, it examines the external view, focusing on the network services provided to the transport layer in end systems. Second, it investigates the internal workings of the network, including data routing, addressing, and congestion control methods. By covering both perspectives, the course thoroughly explains how packet networks support higher-layer protocols and maintain efficient, reliable data transmission.
