Patent number: 8724514Abstract: A method for controlling advertising of routing data to neighbor routers is presented. A list of prefixes is maintained (301) and each prefix is associated (302) with an own indicator vector that contains a data item for each of the neighbor routers so that the data item indicates (304) whether the prefix concerned is to be advertised to the neighbor router concerned. For each neighbor router there is (303) a handling pointer pointing to the prefix that is relevant to the status of an advertising process related to this neighbor router, and the handling pointer is moved forward on the list of prefixes according as the prefixes are advertised to this neighbor router. As there is no need to maintain an own list of prefixes for each neighbor router separately, but only neighbor router-specific entries in the indicator vectors, savings can be achieved in the required memory space.Type: GrantFiled: August 1, 2011Date of Patent: May 13, 2014Assignee: Tellabs OyInventor: Ville Hallivuori
