    Abstract

    Novel business scenarios such as Business Value Networks and Extended
    Enterprizes pose new challenges to enable service value chains across
    heterogeneous organizational boundaries. In these business scenarios,
    service choreographies result into hierarchical structures of added
    value. Service Level Agreements (SLAs), which are contracts between
    consumers and providers, guarantee the expected quality of service
    (QoS) to different stake holders at various levels in this hierarchy.
    So far, the aggregation of SLAs has been treated as a single layer
    composition. Therefore, we address the strong requirement of describing,
    modeling and maintaining this hierarchical SLA aggregation associated
    with service value chains. In this paper we propose a framework to
    enable hierarchical SLA choreography, aggregation, and validation
    for business value networks.
