# A Heuristic Algorithm for Network Optimization of OTN over DWDM Network

## TL;DR

This paper investigates the convergence of OTN and DWDM layers in optical networks, demonstrating that multilayer planning reduces costs at higher traffic volumes, which could improve network efficiency and profitability.

## Contribution

It provides a comparative analysis of network planning costs with and without convergence, highlighting the benefits of multilayer planning for high traffic scenarios.

## Key findings

- Multilayer planning reduces costs at higher traffic volumes.
- Convergence of OTN and DWDM layers offers cost efficiency.
- Network planning with convergence is more effective for high traffic volumes.

## Abstract

While the network traffic has seen exponential increase, the revenues have not maintained the same pace. New methods have to be explored to reduce this gap between traffic and revenue. One such method is convergence in networking layers. In this work, we study the convergence of OTN and DWDM layer from a network planning perspective. We compare the costs of planning networks without and with convergence and show that the multilayer planning offers least cost for higher traffic volumes.
