Point-to-Point and Shared-Medium: examples and advantages of each

Shared medium link: turn-around overhead

how many bits is the distance d worth?

Link utilization for varying link throughput, link length, packet size

When the use of the shared link is demand-driven (packet switching), rather than pre-scheduled (circuit switching), an additional complexity to be handled is arbitration --who will transmit next:

Arbitration Overhead

Single versus multiple parallel transmissions

In this course... only switches with point-to-point links
