To address the problem of service availability, techniques such as bundling and implicit uploading are suggested to increase the swarm lifespan, i.e., the duration between the birth and the death of a swarm, by motivating or even forcing peers to make more contributions. In these systems, it is common for a peer to join a swarm repeatedly, which can introduce substantial bias for lifespan modeling and prediction. In this paper, we present a mathematical model to study the lifespan of a P2P swarming system in the presence of multi-participation. We perform evaluations on three traces and a well-known simulator. The result demonstrates that our model is more accurate than previous ones. %G English %Z TC 6 %2 https://inria.hal.science/hal-01531955/document %2 https://inria.hal.science/hal-01531955/file/978-3-642-30054-7_6_Chapter.pdf %L hal-01531955 %U https://inria.hal.science/hal-01531955 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC6 %~ IFIP-LNCS-7290 %~ IFIP-NETWORKING
