----------------------------------------------------------------------

1. Compute the required length for fiber delay line, assuming
    - a relatively long buffer of 250 packets
    - bit rate of 10 Gb/s
    - buffered cells are ATM cells (packet size 53 octets)

----------------------------------------------------------------------

2. Conclude that fiber transmission losses may be neglected, when
designing optical buffers.
    - use the result of Exercise 1.
    - you may consult Stern&Bala, Chapter 4.

----------------------------------------------------------------------

3. Explain how to produce a delay of 249 packets using the
cascaded switch architecture given below.
    - assume k=3 and m=10.
