Abstract

See full text

User defined routing rules are managed within a primary/backup architecture through continuous replication between home servers and their corresponding presence servers in an automatic manner. User set-up rules are stored and published by a designated presence server to home servers on which the user can register including the user's home registrar and any backup registrars. Changes to the rules may be disseminated and synchronized through comparison of versions and exchange of batches between the presence server and registrars.
