5 Questions
Packet loss occurs when the arrival rate to a link temporarily exceeds the output link capacity.
True
The propagation delay is calculated as dprop = d/s, where d is the length of the physical link and s is the propagation speed.
True
The transmission delay can be calculated as dtrans = L/R, where L is the packet length in bits and R is the link transmission rate in bps.
True
Nodal processing delay typically takes more than a millisecond to check for bit errors and determine the output link.
False
Queueing delay is the time waiting at the input link for transmission and is independent of the congestion level of the router.
False
Test your knowledge about the fundamental concepts of the Internet, including protocols, network structure, performance metrics, security, and packet transmission. This quiz covers topics such as what the Internet is, what protocols are, how packet loss and delay occur, and the different layers of network protocols.
