osmo-remsim End-to-end testbed

Description

There is a testbed designed for CI and longterm tests of the whole suite of components(server, bankd, clients). Contrary to the integration tests in TTCN3, this is a setup with real hardware.

It is a small but not minimal configuration:
  • 1x host with 2 x virtual machines, all running debian 10 buster (virtualization is provided by kvm and libvirt)
  • 1x sysmoQMOD board with 4 modems connected via usb
  • 1x SIM card reader with 5 slots using USB CCID
  • bankd vm:
    • runs osmo-remsim-bankd
    • has a forwarded usb device (5slot cardreader)
  • server vm:
    • runs osmo-remsim-server
    • has a netem script in the network sending path - limiting the delay/latency/jitter/bandwith to 'good' VSAT values
  • hostsystem:
    • runs 4 instances of osmo-remsim-client-st2
    • this cannot be done inside a kvm vm due to bugs/limitations forwarding complex usb devices/hubs (sysmoQMOD is a hub with multiple devices behind)

QMOD

The Qmod has four modems of type "Ericsson F5521gw" installed.
