CONGESTION MANAGEMENT IN A MULTICAST COMMUNICATON NETWORK

摘要

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.

1. A method for managing a congestion in a communication network, said network supporting transmission of a number of multicast data flows, said method comprising,
detecting congestion at a transmission interface of a router of said network: identifying a multicast data flow that is forwarded through said transmission interface and suffering a packet loss; interrupting the transmission of said data flow through said transmission interface downstream of the router and, in case said data flow would be transmitted downstream of the router through said transmission interface only, sending a request to an upstream router for interrupting the transmission of said data flow from said upstream router to said router; and c) inhibiting, for a given period of time, any request to forward said data flow via said transmission interface.
