A notification service for TINA

The paper presents Alcatel's Notification Service which has been designed in the context of TINA. It has been partly developed in the framework of the TINA auxiliary ACTS projects: ReTINA (AC048) and VITAL (AC003). A first prototype was issued in mid 1996. Based on the users' feedback, a second version has been designed and will be delivered by the end of 1997. The paper presents the rationales for such a service and its main features: generic and typed notification, push and pull communication models, filtering subscription, federation fault tolerance, and quality of service. For each feature, a comparison is done with the four actual OMG proposals for a notification service and the rationale for our choices in the light of the TINA use of the service is stressed.
