A smart card based solution to minimize inter-receiver delay jitter

We consider the problem of how to achieve a simultaneous arrival of information at a multitude of recipients for applications where the receivers are noncooperative. 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 the application layer, which does not assume special properties of the core network nodes and can be partially deployed. All necessary functions except a trusted time service are handled in the end systems. At the receivers, a secure hardware performs the security related functions. Additionally, the approach implicitly takes current network load into account, which gives the opportunity to keep the message delivery delay low. An analysis and simulation of the approach shows that the resulting inter-receiver delay jitter can be reduced to the order of tens of milliseconds
