Abstract: 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.

Abstract: A method for serving an aggregate flow in a communication network node includes a plurality of individual flows. The method includes identifying in the aggregate flow, based on serving resources allocated to the network node, individual flows that may be served without substantial detriment to perceived performance, and serving the identified individual flows with priority with respect to the remaining individual flows in the aggregate flow. The method allows the presence of individual flows that may not be served without substantial detriment to perceived performance due to shortage of serving resources to be notified to an external control entity.

Abstract translation: 本文公开了一种用于在通信网络节点中服务聚合流的方法，所述聚合流包括多个单独的流。 该方法包括基于分配给网络节点的服务资源来识别可以被服务的个体流，而不会对所感知的表现造成实质损害，以及针对集合中的剩余个体流优先地为所标识的个体流服务 流。 该方法允许存在可能不被服务的个体流，而不会由于缺少要被通知给外部控制实体的服务资源而对感知到的性能没有大的损害。
