# Traffic Load Uniformity in Optical Packet Switched Networks

## TL;DR

This paper analyzes how traffic load uniformity affects packet loss in optical packet switched networks, revealing that asymmetric traffic patterns can reduce packet loss compared to symmetric ones.

## Contribution

It introduces analytical models based on the Engset traffic model and demonstrates that asymmetric traffic patterns lead to lower packet loss in OPS nodes.

## Key findings

- Asymmetric traffic patterns result in less packet loss.
- Traffic load uniformity significantly influences packet loss.
- Analytical models are developed for OPS network analysis.

## Abstract

A crucial issue in Optical Packet Switched (OPS) networks is packet loss due to contentions. In this paper we study how traffic load uniformity influences the packet loss in a single OPS node. Traffic load uniformity is a measure of the load asymmetry a specific output link in an OPS node receives from its input sources. We develop analytical models based on the Engset traffic model. As a major contribution of this paper, we show that an asymmetric traffic pattern results in less packet loss compared to a symmetric traffic pattern for a single output link in an OPS node.
