# How long delays impact TCP performance for a connectivity from Reunion Island ?

## TL;DR

This paper investigates how the long delays inherent in Reunion Island's internet connection, due to its geographical distance from France, affect TCP performance by analyzing collected TCP traces.

## Contribution

It identifies key metrics to evaluate the impact of high latency on TCP performance in a unique geographical and network context.

## Key findings

- Delay significantly affects TCP throughput and reliability
- Long delays increase retransmission times
- Metrics for delay impact assessment are proposed

## Abstract

TCP is the protocol of transport the most used in the Internet and have a heavy-dependence on delay. Reunion Island have a specific Internet connection, based on main links to France, located 10.000 km away. As a result, the minimal delay between Reunion Island and France is around 180 ms. In this paper, we will study TCP traces collected in Reunion Island University. The goal is to determine the metrics to study the impacts of long delays on TCP performance.
