Goals for this Project

GEC22 -- 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
