Railways See the Benefits of IP Convergence - Customer and Network Operator Perspectives

By Mae Kowalke, TMCnet Contributor

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.

IP Convergence Delivers for Railway Operators

Rail communications have not been immune from the information technology revolution, but any new rail solutions need to be rock-solid since safety is on the line. Rail communications failure is just not an option.

Moving from separate network services to a converged IP/MPLS multi-service network is helping railway operations make a step-change in flexibility and efficiency while reducing total cost of ownership.

IP convergence--and IP/MPLS in particular—bring safety-related train control communications under a single unified architecture while delivering new railway communications flexibility.

One railway operations pioneer, Portugal’s REFER Telecom (the telecommunications subsidiary of Portuguese railway infrastructure manager, REFER E.P.E), has been using a fixed IP communications network since 2004. Since 2008 it has been running on IP/MPLS technology provided by Alcatel-Lucent.
