Abstract
A method of configuring a plurality of rendezvous servers to provide a Host Identity Protocol, HIP, based mobility service to HIP nodes, where the servers are arranged in a hierarchical branching structure. For each HIP node, a Host Identity Tag, HIT, and contact address mapping is registered with a rendezvous server. That server then identifies itself and the HIT to each higher level server within the same branch, without explicitly identifying the contact address to those higher level servers wherein, in use, when a first rendezvous server receives a HIP contact message addressed to a given HIT, if that first server is unaware of the destination HIT, it forwards the message to a higher level server within the same branch and if the first server is not the server at which the HIT is registered but is aware of the HIT, it forwards the contact message to the neighbouring rendezvous server corresponding to the HIT.
