The AB4Rail project contributes to the work programme S2R-OC-IP2-02-2020 objectives by identifying alternative communication bearers (ABs) and communication protocols. The first study in AB4Rail will review the state of art of the considered alternative bearers to select the most promising ones for the Adaptable Communication System (ACS) technical demonstrator TD 2.1. The second study will investigate the optimal/best usage of the current and future communication protocols at application and transport levels for the ACS architecture.
AB4Rail will be targeting an improvement of the ACS performance leveraging on the relevant background of Radiolabs to:
1. Manage multi communication bearers and heterogeneous connection link (bearer independence concept) to guarantee the best performance of a single (multiple) specific rail application(s), by complementing communication bearers, already taken into account in the Shit2Rail (X2Rail 1-2) project;
2. Adopt a top-down approach for developing and managing rail applications in an end-to-end way to guarantee appropriate levels of Quality of Service (QoS) and Quality of Experience (QoE).
In that way the ACS open platform can be enriched by adding additional bearers with mature technologies, to complement the traditional communication bearers (Workstream 1) and Transport and Application protocols optimised for rail applications (Workstream 2).
