Abstract
A computer implemented method and apparatus for an attribute-oriented routing update is described. The method comprises selecting an updated set of attributes in a routing table before selecting a set of updated destinations associated with the selected set of attributes, wherein the attributes are stored in an attribute table as a portion of the routing table and the attributes do not include the conventional network prefixes. An update message that includes the set of updated destinations for the set of attributes is then generated. The method is also extended to extraction of unreachable destinations by using a dummy attribute in the routing table, wherein the dummy attribute is selected first, followed by extracting the unreachable destinations.
