We consider the problem of how to achieve a simultaneous arrival of information at a multitude of recipients for applications where the receivers are non-cooperative. For that reason, we aim at designing an inter-receiver delay jitter fair service for Internet multicast delivery. In contrast to related work, we present an approach at application layer, which does not assume special properties of the core network nodes and can be partially deployed. Additionally, it implicitly takes current network load into account, which gives the opportunity to keep the overall message delivery delay low. Simulation results show the feasibility of the described algorithms and a significant reduction of inter-receiver delay jitter compared to normal multicast delivery.
