摘要:
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.

Method for managing multicast delivery of data packets in communication networks comprising the steps of checking join requests coming from hosts (15) to be a part of a multicast group to determine a delivery policy associated to that host and for the requested group and associating hosts with a multicast group according to their delivery policy.

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.

Disclosed herein is a two-level, network-based application control (NBAC) architecture for monitoring services provided via a packet-based network. The NBAC architecture comprises a Network Trigger System (NTS) provided at a network level to analyze data flows relating to services to be monitored to detect occurrence of configurable events, and to generate and send event reports; and a Usage Status Engine (USE) provided at a control level to configure the Network Trigger System to detect occurrence of events of interest, and to receive and process the event reports from the Network Trigger System to monitor the services.
