Virtual Time: a GPS example

connection ?i {(aik, Lik)}

1 1/3 {(0,1), (4,2)}

2 1/3 {(0,2)}

3 1/3 {(0,2)}

Estimated finish time for p11 = 0 + 1/(1/3) = 3

Estimated finish time for p21 = 0 + 2/(1/3) = 6

Estimated finish time for p31 = 0 + 2/(1/3) = 6

But another packet arrives on connection 1: a12 = 4; L12 = 2
