Priority based LDAP service publication mechanism
View Patent ↗A method and system are provided for directing a client to a preferred service instance. At creation of a service instance, the service binding attribute of the created instance is extended to include assigned domains and associated priorities. There are then two phases to directing a client to the preferred service instance. The first phase is compilation of a list of domains and priorities for the service in response to a query. Upon completion of the first phase, a second phase is executed to determine a preferred service for the client by comparing fully qualified domain name entries and assigned priority entries.
1. A method for directing a client to a preferred service instance, comprising:
storing data in a service binding attribute of a service connection point, said data including adaptive domain data for domains served by said service instance and adaptive priority data associated with said domains, said priority data indicating quality of a match of an associated service instance to domain data;
querying a directory of compiled assigned domain and priority data to each service attribute for all instances of a service;
receiving a list of domain data associated with said priority data for each service instance in response to said query; and
scanning said list for a match for a client machine to a preferred service instance, including determining a preferred service instance for said client based upon: a comparison of a domain data entry in said list with a domain data assignment to said client, and a comparison of a priority entry in said list with a priority assignment to said client responsive to a comparison of said domain data entries resulting in maintaining a current client assignment.
2. The method of claim 1 , further comprising compiling a directory of assigned domain data and priority data associated with each service instance, including each item in said directory having a fully qualified domain name and an associated priority.
3. The method of claim 2 , wherein said list includes one item per pair of fully qualified domain name and an associated priority.
4. The method of claim 1 , wherein said priority data identifies closeness of said service instance to said domain.
