IP Addressing in Train Consists with ROQSTAR Managed Ethernet Switches

For dynamic coupling of train consists to work, a solution for IP device communication is required. For this purpose we consider a network architecture based on the VDV301-2-14 script, where an encapsulation of the wagons is achieved by establishing one wagon-internal and one train-wide IP network each. An introduction to the topic can be found here: Use Case: Dynamic Coupling of Trams.

Network Address Translation (NAT) with ROQSTAR Managed Gigabit Ethernet Switches

In IP networks with a deliberate network segmentation by VLAN and IP subnets oftentimes there are devices which need to communicate across these borders. Usually this is the case for internet or backbone connections or with overarching networks that are used to connect multiple local ones. One common technique used to enable communication from one IP subnet to another is Network Address Translation (NAT), of which there are different variants.
The following application note describes the NAT functionality offered by ROQSTAR Managed Gigabit Ethernet Switches.

Using port-based DHCP with ROQSTAR Managed Ethernet Switches

DHCP allows for a centralized assignment of IP addresses, which dispenses with the need to configure IP addresses statically in every single network device. However, with standard pool-based DHCP the addresses are assigned dynamically, which means that a device will not always have the same address. Compared to a static assignment this makes communication between devices more difficult. Especially in fixed network topologies having a fixed addressing scheme to ensure that a certain device always has the same, known IP address is desirable. This goal can be realized by using port-based DHCP: A device connected to a certain port will always receive the same IP. The following application note describes how to set up port-based DHCP with ROQSTAR Managed Gigabit Ethernet Switches.

Using the OpenAPI of ROQSTAR Managed Gigabit Ethernet Switches

ROQSTAR devices support an API (Application Programming Interface) for applications where automated deployment or monitoring is needed. Using this API the device’s configuration can be managed and status data can be queried. Compliance with OpenAPI specification 3 gives access to numerous tools for code generation and documentation. You can get an overview of the OpenAPI here: Remote Network Management via OpenAPI
