Distributed service creation and distribution
First Claim
1. A method of coordinating access to a data network service comprising:
- maintaining a registry of a plurality of service providers;
receiving a query for a requested data network service from a source, said query including required attributes of said requested data network service;
searching said registry to determine whether a given one of said plurality of service providers in said registry can provide said requested data network service having said required attributes; and
if said given one of said plurality of service providers in said registry can provide said requested data network service having said required attributes, sending information identifying said given one of said plurality of service providers to said source of said query.

Abstract
A service provider is enabled to easily create and distribute data network services over a wide area data network such as the Internet. Powerful distributed computing technology and popular standards like Domain Name Service (DNS) and Extensible Markup Language (XML) may be leveraged to provide a scalable and secure service infrastructure. A directory service utility maintains a registry of service providers of data network services. In response to receiving a query for a particular service, the directory service utility identifies a provider of the particular service to the network connected device. The network connected device may then contact the service provider directly and receive an application (i.e., an executable file) for accessing the particular data network service. Distributed computing features are used to reduce the need for widespread distribution of additional protocols when new services are created. This increases service creation, reduces time-to-market of new services and minimizes services management and maintenance requirements.

12. At a first directory service utility situated in a local service cluster, a method of coordinating access to a data network service comprising:
-
maintaining a registry of a plurality of service providers;
receiving a propagated query for a requested data network service from a second directory service utility situated in a remote service cluster, where said propagated query includes a source of an initial query and required attributes of said requested data network service;
searching said registry to determine whether a given one of said plurality of service providers in said registry can provide said requested data network service having said required attributes; and
if said given one of said plurality of service providers in said registry can provide said requested data network service having said required attributes, extracting said source of said initial query from said propagated query; and
sending information identifying said given service provider to said source of said initial query.
