Abstract: Address management methods and apparatus are provided for a node serving as peer group leader for a peer group of nodes in one level of the hierarchy of a PNNI hierarchical network, whereby the peer group leader represents the peer group to one or more neighboring nodes in the next level up of the hierarchy. The peer group leader has a memory (2) for storing peer group topology data (4), comprising address data which is supplied to the peer group leader from nodes in the peer group and represents addresses for access by the network, and peer group leader topology data (5), comprising address data which is supplied to said neighboring nodes by the peer group leader and represents addresses accessible via the peer group. The address management method comprises: checking whether addresses represented by said address data are accessible via the peer group; notifying said neighboring nodes of changes in the accessibility of addresses so identified; and updating said peer group leader topology data (5) in accordance with said changes.

Abstract: Un método de gestión de direcciones en un nodo que sirve como líder de grupo paritario para un grupo paritario de nodos en un nivel de la jerarquía de una red jerárquica de PNNI por la que el líder del grupo paritario representa el grupo paritario para uno o más nodos próximos en el siguiente nivel superior de la jerarquía, teniendo el líder del grupo paritario una memoria (2) para almacenar datos de topología de grupo paritario (4), que comprende datos de dirección que son suministrados al líder del grupo paritario desde nodos en el grupo paritario y representan direcciones para acceso a través de la red, y datos de topología (5) de líder del grupo paritario, que comprenden datos de dirección que son suministrados a dichos nodos próximos por el líder del grupo paritario y representan direcciones accesibles a través del grupo paritario, caracterizado el método por: comprobar si las direcciones representadas por dichos datos de dirección son accesibles a través del grupo paritario; notificara dichos nodos próximos los cambios en la accesibilidad de direcciones así identificadas; y actualizar dichos datos de topología (5) de líder del grupo paritario de acuerdo con dichos cambios.
