During a bust of S seconds, a total of MS octets are transmitted. A burst empties the bucket (b octets) and, during the burst, tokens for an additional rS octets are generated, for a total burst size of (b + rS). Thus, € b + rS = MS S = b/(M – r) b. S = (250 × 103 )/(23 × 106 ) ≈ 11 msec 15.6 a. b 2 (n) = a1 (n); b 1 (n) = a0 (n) ⊕ a0 (n – 2); b 0 (n) = a0 (n – 1) b. a0 (n – 2) a0 (n – 1) a0 (n) a1 (n) b 2 (n) 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 -68- 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 b 1 (n) b 0 (n) 0 0 1 1 0 0 1 1 1 1 0 0 1 1 0 0 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 ...
