Abstract
This invention relates to methods and apparatus for providing a resilient network database. The invention relates particularly, but not exclusively, to the IP Multimedia Subsystem (IMS). The invention is directed to an interface for a database node comprising: a port for receiving a request for information from a network node; a processor for determining if the database node can respond to said request; and a transmitter for forwarding the request to another database node if the particular database node cannot respond. The invention is also directed to a distributed database comprising a number of database nodes, wherein a request received by one node is forwarded to other nodes in the distributed database if the particular node cannot handle the request.
