QoS in The Internet: Scheduling Algorithms and Active Queue Management

QoS in The Internet: Scheduling Algorithms and Active Queue Management. Principles for QOS Guarantees. Consider a phone application at 1Mbps and an FTP application sharing a 1.5 Mbps link. bursts of FTP can congest the router and cause audio packets to be dropped.

Queueing and Scheduling

Queueing and Scheduling. Traffic is moved by connecting end-systems to switches, and switches to each other Switches: packet switches v/s circuit switches and connectionless v/s connection oriented Data arriving to an input port of a switch have to be moved to one or more of the output ports.
