Creating and sharing knowledge for telecommunications

Project: Dimensioning of Multi-Layer Optical Networks

Main Objective: Modern transport networks make use of transmission in the optical domain and perform the routing in the electric domain. The emergence of devices with routing capabilities in the optical domain creates a new paradigm.

In principle, this new paradigm can increase the networks throughput and reduce the infra-structure costs. The present challenge is to understand how these optical routing modules should be integrated in the networks to obtain more flexible telecommunication infra-structures, with minimum cost of installation, maintenance and management.

These optical routing modules also induce transient effects in the network that is essential to understand and control.

We intend to treat the dimensioning problem with probabilistic/statistics models in detriment of the deterministic models approaches. We intend to obtain simple causal relationships between critical aspects in the dimensioning problem and to obtain results with a high degree of confidence with less computational time.

We are going to focus our research on Multi-Layer Survivable Optical Networks with optical and electric routing, supported by multiple wavelengths (WDM) optical transmission systems and optimized for IP traffic.
