English abstract:
Business-to-Business (B2B) workflow/service
interoperation across Virtual Organisations (VOs) brings
about novel business scenarios. In these scenarios, parts of
workflows (or services) corresponding to different partners
can be aggregated in a producer-consumer manner, leading to
hierarchical structures of added value interpreted as service
value chains. Service Level Agreements (SLAs), which are
contracts between service providers and service consumers,
guarantee the expected quality of service (QoS) to different
stakeholders at various levels of a service value chain. The
essential requirements for such an SLA-based choreography of
services include agile component-based infrastructure to support
the corresponding choreography of their SLAs; proactive
validation of SLAs to prevent violations; reactive validation of
SLAs for penalty enforcement and breach management; and
business enabling requirements such as trust, privacy, security
and automation. In this paper we highlight the significance of
these issues and propose their solutions. We then proceed to
weave these solution components together into a comprehensive
SLA validation framework that blends together two major
systems: a rule based distributed system for SLA validation and
a service monitoring system for the prevention of SLA violations.
