Abstract
The invention is a method that forwards a multicast packet in a connectionless multicast system from an ingress node via a router to a plurality of destinations. In the method, a relation between a value of a receiver update notification and a predefined construction set is stored by the router in a memory. The predefined construction set includes a set of next hops that includes one or more next hops being determined according to local unicast routing information for each destination of a predefined set of destinations. The method associates by the ingress node to a starting destination set the value of the receiver update notification and, including by the ingress node, the value of the receiver update notification in the multicast packet. Upon reception of the multicast packet that includes the value of the receiver update notification, the router determines a predefined subset of destinations and determines for the predefined subset of destinations a next hop of the set of next hops according to the value of the receiver update notification and according to the relation to the predefined construction set.
