Perhaps other mechanisms in a grid fabric might also use multicast to convey information. <AD>IN THEORY YES </AD> What is your opinion on this possibility: When a user submits a job request (via a portal for instance), the job manager would convey the request to other services which trigger the (potential) instantiation of new services. Any new service addresses are returned as part of the instantian process and are conveyed directly to the information services and others. Since the locations (EPRs or WS-Names) of the services are passed around in an event driven model, would it obviated the need for searching (discovery)? <AD>WHERE IS MULTICAST USED HERE, IT CERTAINLY IS APPROPRIATE FOR SERVICES TO ANNOUNCE THEMSELVES WHEN THEY ARE INSTANTIATED. AN INFORMATION SERVICE CAN "LISTEN" TO SUCH ANNOUCEMENTS AND REGISTER SUCH SERVICES DYNAMICALLY. </AD> I thought the naming section was important.

Hi Andreas

Please find revised section on Information services for OGSA 1.5. I have removed Naming, added a small paragraph on INFOD and one on dynamic discovery and made some small edits.

Please read and either accept the changes or comment by Email as it I may not be able to make the normal call.

Thanks
