Runtime Variability and RTT predictors

Performance Predictors Project This repository contains components for managing and evaluating Round-Trip Time (RTT) and variability predictors used in edge computing experiments. The system is modular, with separate containers for managing predictors, running individual prediction services, and post-processing experimental results. Repository Structure prediction_manager Purpose:Hosts the predictor manager responsible for orchestrating both RTT and variability predictors. Container:Runs as a standalone Docker container. Execution:Built using the provided Dockerfile and launches src/main.py. rtt_predictor Purpose:Contains the RTT prediction processes. Container:Runs independently in a Docker container. Execution:Built using the provided Dockerfile and launches src/main.py. variability_predictor Purpose:Contains the variability prediction processes. Container:Runs independently in a Docker container. Execution:Built using the provided Dockerfile and launches src/main.py. postprocessing Purpose:Provides scripts for analyzing predictor performance at the end of experiments. Functionality: Evaluates predictor accuracy, overhead, and configuration changes over the experiment duration. Uses raw data and stores results in the data/ subdirectory. Data The raw experiment data and analysis results are stored in the postprocessing/data/ directory. This directory is structured to separate raw logs from processed results.
