GEORGIA TECH LORRAINE GEORGIA INSTITUTE OF TECHNOLOGY School of Electrical and Computer Engineering ECE 6543 Fiber Optic Network Spring Semester 2009 Homework #4 Date due: March 9th Problem 1 Consider a two-channel, four-node broadcast-and-select WDM network. Each node is equipped with FT-TR. Design a fixed frame assign- ment schedule for the following traffic matrix. Assume that the tuning time is equal to one time slot. Be sure to indicate which node is tuning its receiver during which slot.
