Abstract

The invention relates to a method for establishing a multi-homed connection with a number n of paths between two components of a communication network. In this case the components feature at least n communication addresses, and the communication addresses of at least a first component are translated in the connection path. The method features the following steps: Determination by the components of n translation relationships of the n communication addresses provided for the n paths; and setting up the multi-homed connection through establishing the n paths on the basis of the translation relationships determined. The n translation relationships are exchanged completely or partly in each case by the exchange of test messages for k (k=1 . . . n) communication addresses between the components, which deliver k translation relationships. In this case the test messages are selected so that the translation of the communication addresses for test messages is identical to the translation of the communication addresses for the later paths of the multi-homed connection. Alternatively translation relationships can be determined by setting up m (m=1 . . . n) single-homed connections between the components. In this case there can preferably be provision, to prevent a multiple setup and cleardown of connections or paths, for the single-homed data connections to be merged as paths into the multi-homed connection.
