Web Services Management Network: an overlay network for federated service management

TLDR

WSMN targets management of Web services that interact across administrative domains, involving multiple stakeholders such as business-to-business, service provider interconnections, and help desks. The paper introduces the architecture, object model, components, and protocols of the Web Services Management Network (WSMN) for federated service management. WSMN’s architecture is based on implicit SLAs, employs a network of proxy intermediaries between services and the outside world, and exchanges control information to agree on monitoring scope and visibility.

Abstract

We introduce the architecture, object model, components, and protocols of a management overlay for federated service management, called Web Services Management Network (WSMN). WSMN targets management of Web services that interact across administrative domains, and therefore typically involves multiple stakeholders (examples are business-to-business, service provider interconnections, help desks). The architecture is based on (implicit) SLA to formalize relations across domains. It relies on a network of communicating service intermediaries, each such intermediary being a proxy positioned between the service and the outside world. WSMN also exchanges control information to agree on what to monitor, where to monitor, and whom to provide visibility.
