CHEM 301 Physical Chemistry I Homework 1- Chapters 1-2 1. Calculate the value of CP at 298 K and 1 atm pressure predicted for CH4(g) and C2H4(g) by the classical….

## What are the (P, B) parameters in b/s and bits for each case ?

For a CBR connection, here are some values from an ATM operator:

peak cell rate (cells/s) 100 1000 10000 100000

CDVT (microseconds) 2900 1200 400 135

1. What are the (P, B) parameters in b/s and bits for each case ? How does T compare to τ ?

2. If a connection requires a peak cell rate of 1000 cells per second and a cell delay variation of 1400 microseconds, what can be done ?

3. Assume the operator allocates the peak rate to every connection at one buffer. What is the amount of buffer required to assure absence of loss ? Numerical Application for each of the following cases, where a number N of identical connections with peak cell rate P is multiplexed.

case 1 2 3 4

nb of connnections 3000 300 30 3

peak cell rate (c/s) 100 1000 10000 100000
