Zusammenfassung:	It is disclosed a method for managing a congestion in a communication network supporting the transmission of multicast data flows. The method comprises, upon detection of a congestion at a transmission interface of a router: identifying a multicast data flow being forwarded through the transmission interface and suffering a packet loss; interrupting the transmission of the data flow through the transmission interface downstream the router and, in case the data flow would be transmitted downstream the router trough the transmission interface only, sending a request to an upstream router for interrupting the transmission of the data flow from the upstream router to the router; and inhibiting, for a given period of time, any request to forward the data flow via the transmission interface.
