Abstract: An address for controlling transmission of routing through a network is obtained by means of input from a combination of network terminals. Initially, address describing data is received from a user via a source terminal. A control circuit determines whether the address describing data is sufficient to define an address of a destination. If not, the control circuit uses the address describing data to extract information must be met by the destination, but for which it is not known for specific destinations whether it is met. The information may define a desired property of the destination for example, or a mutual relation between the user and the destination. The control circuit then transmits a confirmation request to one or more possible destinations, to ask whether information relates to the possible destination. If a positive confirmation is received back from a possible destination, the address of this possible destination is used.

Abstract: Retrieval of address data for control of routing through a network, such as a telephone network or an e-mail network is supported by a database with pre-stored address resolution information. Input from users is used to expand the database. When a first user inputs information that links a destination in the network to an information item, the database is expanded by adding a record that links the information item to a source identifier of the first user and a destination identifier of the destination. Subsequently, the added record is compared with address describing data from a second user. A destination address may be derived from the address describing data for example when at least one attribute associated with the second user and the source identifier match and at least part of the address describing data matches the information item.

Abstract: A database of pre-stored information is provided to support address resolution to determine addresses that can be used to control routing through a network such as call routing through a telephone network or e-mail routing. A user is enabled to enter address describing data, which the user can distinguish into different information parts. The network, address resolution equipment determines an identifier of an intended destination based on the information parts, if need be by combining it with the database. The result is used to control routing of data through the network. Furthermore, the address describing data is inspected for information parts that were distinguished by the user and that applied to the intended destination but were by themselves insufficient to determine the identifier.

Abstract: A system for overload protection in a data network (1) for information delivery, comprising a server transmitting a plurality of unicast content messages (5, 5?) comprising a substantially identical content, communicatable via a data network (1), having unicast and distribution capabilities, to a plurality of terminals (3, 3?) respectively, a message interceptor (8), comprising a computer, arranged for receiving and grouping the plurality of unicast content messages (5, 5?) into a distributable content message (6) comprising the substantially identical content, the computer further arranged for communicating the distributable content message (6), to the plurality of terminals (3, 3?) via the data network (1), whereby the plurality of unicast content messages (5, 5?), with the substantially identical content, for the plurality of terminals (3, 3?) are routable by the data network (1) to the message interceptor (8), and the distributable content message (6) is distributable by the data network (1) to the plural
