COMP536: Secure and Cloud Computing

This repository contains assignments for the Rice COMP536 course on Secure and Cloud Computing.

Repository Structure

• HW1/:
  • part1/: Multithreading experiments with program.c and interleaving analysis.
  • part2/: Performance comparison of version1.c and version2.c with execution time analysis.
• HW2/:
  • Implementation of P4-based load balancers with ECMP load balancing, per-packet load balancing, and flowlet switching.
  • Includes scripts for generating random flows, querying byte counters, and analyzing packet reordering.

Key Files

• HW1/part1/program.c: Multithreaded program for interleaving analysis.
• HW1/part2/version1.c & version2.c: Two versions of a program for performance comparison.
• HW2/multi_lb.p4: P4 program implementing the load balancer.
• HW2/random_flows.py: Script to generate random flows for testing.
• HW2/query_bytes.py: Script to query byte counters from the load balancer.
• HW2/receive_ooo.py: Script to analyze out-of-order packet delivery.

Usage

1. HW1:
   • Compile using the provided Makefile.
   • Run program.sh (part1) or run.sh (part2) for experiments.
2. HW2:
   • Put the folder under ~/tutorials/exercises
   • Run make clean && make run
   • Run ./receive_ooo.py on H2
   • Run ./random_flows.py --mode 1 on H1
   • See report (HW2-hc105.pdf) for more details

Prerequisites

• GCC and make for C programs.
• Python 3 with scapy.
• P4 development environment - setup tutorial
