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.
