If the next packet arrives 0.40 seconds later, 400 bytes are added to the token buckets ((.40 * 8000)/8).
Therefore, the conform token bucket now has 1000 bytes (the maximum number of tokens available in the
conform bucket) and 200 bytes overflow the conform token bucket (because it only 200 bytes were needed
to fill the conform token bucket to capacity). These overflow bytes are placed in the exceed token bucket,
giving the exceed token bucket 300 bytes.
If the arriving packet is 1000 bytes, the packet conforms because enough bytes are available in the conform
token bucket. The conform action (transmit) is taken by the packet, and 1000 bytes are removed from the
conform token bucket (leaving 0 bytes).
If the next packet arrives 0.20 seconds later, 200 bytes are added to the token bucket ((.20 * 8000)/8). Therefore,
the conform bucket now has 200 bytes. If the arriving packet is 400 bytes, the packet does not conform because
only 200 bytes are available in the conform bucket. Similarly, the packet does not exceed because only 300
bytes are available in the exceed bucket. Therefore, the packet violates and the violate action (drop) is taken.
