Fundamental aspects of network Design and Analysis: – Architecture Layering Topology design – Protocols Pt.-to-Pt. Multiple access End-to-end

Multiple Access Shared Transmission Medium a receiver can hear multiple transmitters a transmitter can be heard by multiple receivers the major problem with multi-access is allocating the channel between the users; the nodes do not know when the other nodes

An interesting property of an M/M/1 queue, which greatly simplifies combining these queues into a network, is the surprising fact that the output of an M/M/1 queue with arrival rate λ is a Poisson process of rate

When the receiver detects errors in a packet, how does it let the transmitter know to re-send the corresponding packet? Systems which automatically request the retransmission of missing

Optimal Routing View routing as a “global” optimization problem Assumptions: – The cost of using a link is a function of the flow on that link
