METHOD AND DEVICE FOR THE POLICY-BASED MULTIPLE ENUM DOMAIN RESOLUTION BY MEANS OF MODIFIED DNS RESOLVERS

摘要

The invention relates to a method and devices for determining addresses in various ENUM trees by means of a modified ENUM resolver which has a plurality of interfaces to ENUM clients and a plurality of interfaces to different ENUM nameservers of different trees. The method according to the invention is characterized by the following steps: receiving the ENUM query from an ENUM client; modifying said query so that the query can be sent in parallel to the plurality of different ENUM nameservers of different trees; parallel transmission of the ENUM queries to the plurality of different ENUM nameservers of different trees; processing the results of the parallel ENUM queries; forwarding a result of the parallel ENUM queries to the ENUM client.
