CSCD58-Assignment-4

• Programming portion for Computer Networks (CSCD58) Assignment 4 done by Jacky Chen. Please see below for a breif description for each question. This repository only contains Q3 and Q4. For more information on CSCD58, please click here.

• Each question is documented with a README.md and results.md file, the latter being in the form of an informal written analysis to hands on questions with regards to the problems investigated.

• DISCLAMER: this mini-project was made for the programming portion of my assignment, but the testcases and additional documentaion are entirely done by my own discretion.

Q3 - Simulating Ethernet Capture Effect

• This question focuses on doing a hands on experiment with the ethernet capture effect, which can be found here.

• The testcases folder has different testcases for Q3, feel free to add any as you see fit. There are also additional resources to see the results in matplotlib for Python (TODO).

• There is also an additional file called Handsimulation.md that is a hands on activity for actually conducting host colisions when attempting to transmit data.

Q4 - Simulating Intervals of Transmission

• This question focuses on simulating ethernet transmissions, where the interval between consecutive attempts can be defined using the following random variable:

  $$X = -\lambda log(u)$$ $$\text{Where u is in the interval } 0 \leq u \leq 1$$

• The current attempt will collide with another attempt if it is close to its slot time.

• Again, the testcases folder has different testcases for Q4, plus additional resources to see the results in matplotlib for Python (TODO).
