Abstract

Link information is obtained about new or changes links in a communications system having a plurality of domains. The link information concerning a link between a first and a second domain comprises at least four pieces of information, domain identity of the first domain, domain identity of the second domain, link end identifier for a first end of the link, and link end identifier for a second end of the link. The link information is cascaded through the communications system by providing the link information stepwise from one domain to an adjacent domain. This is achieved by spreading the obtained link information to adjacent domains and by distributing link information received from adjacent domains to further adjacent domains. Preferably, the link information is compiled and access to the compiled link information is provided for creation of a system link map.

Method for providing topological map information of a communications system having a plurality of domains, comprising the steps of:

obtaining, in a first domain, information about a first link, a first end of which being connected to said first domain;
spreading link information about said first link from said first domain to a domain adjacent to said first domain;
said link information about said first link comprising:
domain identity of said first domain;
link end identifier for said first end of said first link;
domain identity of a second domain to which a second end of said first link being connected;
and link end identifier for said second end of said first link;
receiving, in said first domain, link information about a second link from a domain adjacent to said first domain;
and distributing said link information about said second link to a domain adjacent to said first domain.
