Railway operators are preparing for a higher-bandwidth future. To keep pace, the industry is defining what the next-generation of railway transmission networks will look like. So are you ready?

Current railway transmission networks are already at their limits, with no bandwidth left over to support innovations such as voice and data communications and machine learning. Many networks are also going end-of-life, making network evolution a major and pressing priority for operators.

Looking to the all-IP future

With these challenges in mind, railway operators are looking to deploy new, more powerful transmission networks based on IP technology. The key benefits of this approach include:

Bandwidth on demand
enabling operators to deploy innovative new voice and data applications that improve operational efficiency and the passenger experience

  Key_Icon.png  

Lower network costs
with costly legacy infrastructure retired and critical and non-critical applications converged on a single, efficient IP network

Simplified management and support
with a single set of tools to manage the converged network infrastructure

Reduced operational risks
based on infrastructure that will be supported by manufacturers for years to come

 

Barriers to uptake

While the benefits of all-IP transmission are compelling, there are still significant barriers for operators to overcome. These include:

                             Umbrella_Icon.png  

Potential IP network security risks
including data theft, malware, unauthorised network access and denial of service attacks
presented by inter-connected, “open” IP network technologies

Migration risks
which, if not managed correctly, could impact on the availability of mission-critical railway applications and services

 

Three possible ways to IP

Operators are exploring a number of potential future scenarios for migrating to IP transmission networks. These include:

Hybrid TDM and IP packet networks deployed in parallel
This approach supports a smooth migration path from legacy to IP, but running two networks concurrently is complex and costly.

Multi-Protocol Label Switching (MPLS)
MPLS is scalable and protocol-agnostic, but it also has features for prioritising traffic that could downgrade mission-critical applications with disastrous results.

MPLS Transport Profile (MPLS-TP)
this uses the same data plane principle as IP/MPLS, but without the features that could downgrade mission-critical transport services. It also needs significantly less memory and processing power than MPLS, making it a highly efficient protocol for operators, and our recommended migration path to all-IP networking.
