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.
