For a host machine that uses the token bucket algorithm for congestion...
Given
Maximum burst rate, M = 20 MB
Token arrival rate, P = 10 MB
Constant rate(bucket o/p), P = 10 MB
Bucket capacity, C = 1 MB
Time for 1 MB, S = C/(M-P)
=1/(20-10) = 0.1 sec
For the total message of 12 MB is 1.2 sec

For a host machine that uses the token bucket algorithm for congestion...
To determine the minimum time required to transmit 12 megabytes of data using the token bucket algorithm for congestion control, we need to consider the capacity of the token bucket, the maximum output rate, and the rate at which tokens arrive.

Given information:
- Token bucket capacity: 1 megabyte
- Maximum output rate: 20 megabytes per second
- Tokens arrive at a rate to sustain output at a rate of 10 megabytes per second
- Data to be transmitted: 12 megabytes

Let's break down the steps to calculate the minimum time required:

1. Determine the time required to transmit the 1-megabyte token bucket capacity:
- Time = Capacity / Output rate
- Time = 1 megabyte / 20 megabytes per second
- Time = 0.05 seconds

2. Calculate the time required to refill the token bucket:
- Tokens arrive at a rate of 10 megabytes per second
- Time to refill = Capacity / Arrival rate
- Time to refill = 1 megabyte / 10 megabytes per second
- Time to refill = 0.1 seconds

3. Calculate the effective output rate taking into account the token arrival rate:
- Effective output rate = Maximum output rate - Arrival rate
- Effective output rate = 20 megabytes per second - 10 megabytes per second
- Effective output rate = 10 megabytes per second

4. Calculate the time required to transmit the 12 megabytes of data:
- Time = Data size / Effective output rate
- Time = 12 megabytes / 10 megabytes per second
- Time = 1.2 seconds

Therefore, the minimum time required to transmit the 12 megabytes of data using the token bucket algorithm is approximately 1.2 seconds.
