Consider a Token Bucket filled at a rate r $=5000$ bytes$/$sec$.$ The Token Bucket has

a capacity of $5000$ bytes. Assume that the bucket is full when the first packet arrives.

Packet arrivals are indicated with upward arrows in Fig. $7.$ Packets arrive at the times

indicated $0,\mathrm{.}2,\mathrm{.}5,\mathrm{.}75$ and $1$ seconds. The packet sizes are indicated at the foot of each

arrow, e$.$g$.4000,2500,2400,2800,2500$ bytes. Assume the Token Bucket drops noncompliant packets. Establish which packets will be forwarded.
