Ejercicio 1 - 2017

Paquete	A	A-R1	R1	R1-R2	R2	R2-B	B
1	0s	2s	2s + 5us	6s + 5us	6s + 10us	7s + 10us	7s + 15us
2	2s	4s	4s + 5us	10s + 5us	10s + 10us	11s + 10us	11s + 15us
3	4s	6s	6s + 5us	14s + 5us	14s + 10us	15s + 10us	15s + 15us
4	6s	8s	8s + 5us	18s + 5us	18s + 10us	19s + 10us	19s + 15us

a) El primer bit de A tarda 6s + 15,25us en llegar a B

6s + 10us + 0,25us + 5us = 6s + 15,25us

b) Tardan 19s + 15us en llegar los 4 paquetes de A a su destino B

c1) Tasa Enlace A-R1 = 0,421

8s / 19s + 15us = 0,421

c2) Tasa Enlace R1-R2 = 0,8421

[(18s + 5us) - (2s + 5us)] / 19s + 15us = 0,8421

c3) Tasa Enlace R2-B = 0,21

[ [( 7s + 15us) - ( 6s + 10us)] + [(11s + 15us) - (10s + 10us)] + [(15s + 15us) - (14s + 10us)] + [(19s + 15us) - (18s + 10us)] ] / 19s + 19s + 15us = 0,21 // [4 x (1s + 5us)] / 19s + 15us = 0,21
