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

Service times M/G/1 General independent Poisson arrivals at rate λ Service time has arbitrary distribution with given E[X] and E[X2] – Service times are independent and identically

• Why need networks • History of Networks • Network Classification • Layered Network Model

• Problem • System Modeling – Vacation model – Power efficiency – P-K formula of Mean delay • Performance Tradeoff • Conclusion

Carrier Sense Multiple Access (CSMA) In certain situations nodes can hear each other by listening to the channel “Carrier Sensing” CSMA: Polite version of Aloha

Queueing Systems Used for analyzing network performance In packet networks, events are random Random packet arrivals
