  1. \[ d_{\text{prop}} = \frac{m}{s} \]

  2. \[ d_{\text{trans}} = \frac{L}{R} \]

  3. \[ d_{e2e} = d_{prop} + d_{trans} \]

  4. Leaving host A?

  5. Still in wire.

  6. Inside host B.

  7. Just solve lol..

2

First solve \(d_{trans} = \dfrac{1500\cdot8}{2\cdot1024\cdot1024}\)

  1. \[d_q = 4.5 \times d_{trans}\]

  2. \[d_q = \left( n + \frac{L-x}{L} \right) d_{trans}\]

3

I sian to calculate

4

  1. \(N+1\)

  2. \(\dfrac{N(N-1)}2\)

  3. part a saves money and part b is very fault-tolerant
