As greater demand is being placed on Railway operators to deliver services that are more bandwidth hungry, many are starting to make the switch away from the SONET/SDH architectures that have traditional run their communications network and move toward the more robust IP/MPLS architecture. In fact, Europe is illustrative of this with rail transportation systems in Milan, Paris and Portugal already enjoying the operational and customer experience benefits of making the move.
There are many reasons why railways are using IP/MPLS for their communications networks but two major ones are:
- IP/MPLS offers high network availability and resiliency through “Non-Stop” technologies such as Non-Stop Routing (NSR), Non-Stop Services (NSS), Link Aggregation Group (LAG) and Fast ReRoute (FRR).
- IP/MPLS enables traffic engineering and isolation, since railway communications cannot afford to fail.

TDM just doesn’t cut it any longer when it comes to rail communications. Railway operations decision-makers the world over are moving from TDM-based rail solutions to a single IP-based communications network that maximizes bandwidth and delivery true multi-tenancy. When it comes to communications, rail solutions in 2013 are all about IP convergence.
“The necessity of an IP network transformation is due to the increasing need to host more services and its ability to converge these onto a single piece of infrastructure to provide a truly multi-service network,” Stefano Pasetti, director of mobile and telecommunications for Milan’s metro rail service provider, Azienda Trasporti Milanese (ATM), said recently in a blog post by Alcatel-Lucent.
