A method of regulating traffic in a telecommunications network, including a first step of detecting a fault affecting a node or a link of the network. The second step below is then executed: the nodes located immediately upstream of said node/link that experienced the fault forward to the latter the registration requests sent by users of the network, to the extent that the throughput of said registration requests is below a predetermined clipping threshold associated with the registration requests; if the throughput of registration requests exceeds said clipping threshold, the excess requests are not forwarded to the node/link that experienced the fault, and the network sends to each user that sent a request refused in this way, a response prompting that user to observe a time-out period, said response specifying the recommended duration of said time-out period. Application in particular to IP networks using SIP signaling protocols.
