Abstract overlay networks have been considered enablers of efficient management for decentralized, large scale service deployments. A Content Delivery Network (CDN) is an example of service falling within this category. The result of our research is WebDMF, a management framework for distributed services based on the Web-Based Enterprise Management (WBEM) family of specifications. Abstract design, combined with a middleware layer of entities called "Representatives", makes WebDMF suitable for the management of a variety of services. Details related to the management of each particular service are detached from the representative logic. This paper discusses how WebDMF can be used for the management of CDNs. A WBEM provider resides on each host participating in the service deployment and implements CDN-specific operations. WebDMF representatives decentralize, unify and coordinate those on a deployment scale. Preliminary measurements on an emulated network topology are also presented as an indication of the solution's viability and scalability.

This paper presents WebDMF, a Web-based Framework for the Management of Distributed services. It is based on the Web-based Enterprise Management (WBEM) family of standards and introduces a middleware layer of entities called "Representatives". WebDMF can be integrated with existing WBEM infrastructures and is not limited to monitoring. On the contrary, it is capable of actively modifying the run-time parameters of the managed application. Its design is abstract and suitable for a variety of distributed services, such as grids and content delivery networks. The paper includes a discussion on WebDMF's design, implementation and advantages. We also present experiments on an emulated network topology as an indication of the framework's viability.

WebDMF is a Web-based Framework for the Management of Distributed services. It is based on the Web-based Enterprise Management (WBEM) standards family and introduces a middleware layer of entities called "Representatives". Details related to the managed application are detached from the representative logic, making the framework suitable for a variety of services. WebDMF can be integrated with existing WBEM infrastructures and is complementary to web service-based management efforts. This paper describes how the framework can be used to manage grids without modifications to existing installations. It compares the proposed solution with other research initiatives. Experiments on an emulated network topology indicate its viability.
