Abstract:
1. A method for establishing filtering for incoming data packets to be received from a network by a receiving device having a host system comprising an operating system and network protocol stack, and a network interface device, comprising the steps of the operating system: programming the network interface device to deliver future incoming packets of a first multicast group to N>0 user level end-points, in a manner that at least part of a header of the future incoming packets, including an identification of at least one of the first multicast group and the respective user level end-point, bypasses the operating system network protocol stack; receiving a request for at least one further user level endpoint to join the first multicast group; and in response to the step of receiving, causing the operating system to forward future incoming packets of the first multicast group to the at least one further user level end-point.
