English abstract:
For today´s Traffic Management Systems (TMS),
availability is a key concern. Failures in the system limit
its availability and have direct impact on the total cost of
ownership (TCO) through additional maintenance costs. Therefore,
availability parameters are often subject of contracts (so
called Service Level Agreements (SLAs)) between system owners,
maintenance contractors, and component vendors. With the
growing complexity of such systems by means of multi-vendor
environments consisting of various subsystems and components
interconnected over numerous levels of hierarchy, enforcement
of these agreements is getting a complex task. Therefore, advanced
SLA enactment strategies are necessary, which include
appropriate concepts that support the mapping of low-level
resource metrics like the up- and down-time of a particular
component to high-level application specific SLA-parameters
(such as system availability).
In this paper, we show the application of the LoM2HiS framework
as an example technology for the automatic enforcement
of availability SLAs in the field of TMS. We discuss possible
SLAs for TMS and the required adoptions to the framework in
order to meet the application-specific needs. Finally, we present
first simulation results.
