Resilient DataDelivery inDelay BoundedOverlay Multicast

Overlay multicast hasbeenproposed asan severe performance degradation mayhappeninoverlay alternative schemetoprovide one-to-many ormany-to-manymulticast. datadelivery onInternet. However, sincedatadelivery is Toachieve highdatadelivery ratio, several schemes have entirely dependent onreplications oneachgroup member, ifone beenrecently proposed.
