Ringing suppression in CAN FD networks
... In CAN FD networks with more than two nodes, a ringing is generated by the reflections of communication voltage wave, which occur because of impedance mismatches in a network at the signal transition frequencies. The impedance mismatches occur mainly at not-terminated nodes and the junction. When a ...

... Example: Circuit vs. Packet Switching • Suppose host A sends data to host B in a bursty manner such that 1/10th of the time A actively generates 100Kbps and 9/10th of the time A sleeps – Under circuit switching, given a 1Mbps link, how many users can be supported? • Answer: 10 with no delays for an ...
