CA 2216337

Apparatus and method for using an access level portion of an address to control the level of access for subscribers in a metropolitan area network. The address is assigned to the subscriber terminal either dynamically by the network head-end, or is permanently assigned. The network head-end controls which of various services are offered tosubscribers based on the access level portion of the address. If a subscriber's identity mandates a different level of access than dictated by the access level portion, an address filter is installed by the network head-end. The invention lends itself to use in an internet protocol based metropolitan area network of the type that makes use of the cable TV system.

L'adresse est affectée au terminal d'abonné soit de façon dynamique par la tête de ligne du réseau, soit en permanence. La tête de ligne du réseau détermine lesquels des divers services sont offerts aux abonnés en fonction de la partie niveau d'accès de l'adresse. Si l'identité d'un abonné demande un niveau différent d'accès que celui qui est dicté par la partie niveau d'accès, la tête de ligne installe un filtre d'accès. L'invention convient pour un réseau métropolitain conforme à un protocole internet, du genre de ceux qui utilisent le système de télédistribution.
