CN Leaky bucket

Question

Assume the following configuration:-

Bucket capacity = 1Mbps

O/p Rate:- 8 Mbps

Token rate:- 6 Mbps

Now by using C+PS=MS formulae i can see that the burst of .5 can be handled by this. But can some one show me mathematically what will happen if a burst of 1 sec will come?

Comments

it can never transfer burst of 1s..

B.T means burst time.

B.T= c/(8-6), where 'c' is stored tokens in token bucket at some instant., now

c <=1MB (max capacity of bucket)

therfore,

B.T <= 1/(8-6)

B.T <=0.5

sir can you explain some more concept of token bucket to solve numerical like
using this, can you compute the number of bits transmitted before the flow depeletes its token

Let me explain according to question bucket capacity is 1Mbps and we want a output rate of 8 Mbps and token rate(at which token is to be place in bucket) is 6 Mbps.we have the formula

Capacity+Token rate=Output rate   for maximum data transfered to another network
1+6t=8t  

this t wil give u how long u can send 8 Mbps.and u are asking for burst time for 1 sec

just put t=1(1+6!=8) means for 1 sec it cannot send data at 8Mbps

whereas if u put t=0.5 (1+6*0.5=8*0.5)

(1+3==4) can send 8 Mbps for 0.5 sec max.

I hope it will help u ):
