Virtual Switch Supporting Time-Space Partitioning and Dynamic Configuration for Integrated Train Control and Management Systems
Hongjie Fang, Roman Obermaisser · 2018
In the railway domain, an execution environment supporting data flows of mixed-criticality applications is an open research problem towards higher integration of future Train Control and Monitoring Systems (TCMS). Compared to the avionic and automotive domains, train inauguration deals with changes of train composition and configuration and is a specific requirement of the railway domain. The statically configured communication channels of other domains need to be extended, in order to cover the requirement of dynamic configuration for train inauguration. In this paper, we propose a virtual switch that ensures temporal and spatial partitioning between data flows of the TCMS applications hosted on the same computing node. The switch leverages the Software-Defined Networking (SDN) paradigm to be reconfigurable in order to cover the train inauguration requirement.
