Abstract This paper explores in detail the aspects of service level fault detection. We present the design and implementation of service level fault detection mechanism with SLA in WBEM-based inter-AS traffic engineering (TE). We extended the Service Location Protocol (SLP) based service discovery mechanism with the Universal Plug and Play (UPnP), and included the WBEM providers for UPnP devices. We also designed the DMTF MOF (Managed Object Format) for service discovery and SLA management in order to handle service violation. The UPnP Event Notification mechanism, service violation handling, and C++ based provider implementation on OpenPegasus WBEM are explained in detail. From the performance analysis of experimental implementation, the UPnP-based SLA violation detection can be processed almost 3 times faster in inter-domain networks compared with the SNMP-based fault notification.
