Abstract : Nowadays, people using live video streaming applications in the Internet are gaining momentum. Client/server model is the simple way to provide video streaming to multiple users. However, this model is not attractive due to server overload/failure and not sharing the client resources. In contrast, Peer to Peer (P2P) approach offers an advantage of creating a self-organizing network. Each byte of data is very important, as these applications demand a high Quality of Service (QoS). Peer failure and/or link failure may cause an interruption in the video delivery. Hence creating a reliable overlay is the primary concern in the streaming system. In this paper, we propose reliability approaches named RA:1, RA:2, RA:3, RA:4, and RA:5 for a hybrid overlay consists of tree and mesh-clusters (MC), where Cluster Heads (CH) are connected to the leaf of the tree. We evaluate and analyze the performance of each approach in the presence of node and link failures and indicate the best among them. RA:5 uses 60.5% more additional connections than RA:1 approach, and it achieves the highest frame success ratio of 99.32%.
