Linked Prepare: Simplifying the onboard community

Within the first weblog on this weblog collection I shared that passenger volumes for city railways, automated individuals movers (APMs), and different types of mass transit proceed to develop. To fulfill growing demand whereas assembly security, passenger expertise, and operational effectivity targets, rail operators are ramping up investments in revolutionary know-how options.


Probably the most vital is Communications-Primarily based Prepare Management (CBTC). Within the easiest of phrases, CBTC places passenger rail on “auto-pilot.” This excessive degree of automation provides important advantages for rail operators and their passengers. However CBTC additionally introduces new networking challenges, together with the necessity for an easier but extra highly effective community on board every practice automotive.

With the transfer to CBTC, rail operators are taking a contemporary have a look at their onboard practice community, implementing a multiservice basis that shifts from disjointed proprietary networks to a standard IP community.

At Cisco, we’ve constructed a community structure that each strengthens and simplifies the onboard practice community. As a part of Cisco’s Linked Prepare answer, we offer a resilient infrastructure able to supporting quite a few providers and use instances. Whether or not supporting important functions akin to CBTC, or non-vital functions akin to passenger WiFi, CCTV, infotainment, digital signage and point-of-sale programs, the Cisco Linked Prepare onboard community offers the wanted bandwidth, reliability, and safety.

A linchpin of our structure is the Cisco Catalyst IE3400 Rugged Sequence. This next-generation, IP67-rated switching platform is designed to supply enhanced network-based safety, segmentation, and visibility in probably the most demanding environments. It could actually stand as much as the tough situations rail operators typically face akin to heavy vibration, excessive climate, publicity to water and dirt. Moreover, it’s compliant with the stringent onboard rail business requirements.

Along with bodily sturdiness, cyber safety is one other space of power for the IE3400 switches. As a result of they’re powered by Cisco IOS XE, a next-generation working system, safety, and belief are inbuilt through Safe Boot, picture signing, and the Cisco Belief Anchor module.

The Cisco Catalyst IW9167 Sequence entry level is one other key participant in our onboard community structure. This entry level offers dependable wi-fi connectivity for mission-critical functions on board rail automobiles. It could actually function as Wi-Fi 6 or Cisco Extremely-Dependable Wi-fi Backhaul – providing flexibility and mobility to accommodate evolving wants.

When working in Wi-Fi mode, it offers Wi-Fi connectivity to rail personnel and passengers inside the practice. When connectivity supplied from Cisco IW9167E (CURWB) or Cisco FM4500 wi-fi radio, it delivers fiber-like train-to-ground communication for each important and nonvital functions. In both mode, it delivers the excessive degree of bandwidth that fashionable rail programs – and their Wi-Fi-dependent passengers – require.

A easy and dependable onboard community is crucial to the success of CBTC programs. One other vital element is resilient and secured trackside infrastructure – a subject I’ll dive into in my subsequent submit.
