2. GENI in your Classroom GENI NICE: GENI Based Course Modules Develop curricular modules for teaching core networking concepts in an undergraduate networking class Modules based on concepts from two widely used textbooks (Kurose and Ross, Tanenbaum and Wetherall) Example topics: TCP congestion control, TCP throughput, traffic generation, IP routing and forwarding, router buffering http://geni.web.unc.edu 11/10/20152

3. Example 1: TCP Congestion Control GENI NICE: GENI Based Course Modules 11/10/20153 cwnd: TCP sender congestion window size additively increase window size … …. until loss occurs (then cut window in half) time TCP congestion control: AIMD (Additive Increase Multiplicative Decrease)
