Scalable P2P Multicast Protocols
Research Guide
What is Scalable P2P Multicast Protocols?
Scalable P2P multicast protocols enable efficient one-to-many group communication in peer-to-peer networks using tree, mesh, or hybrid topologies to minimize delay, branching factor, and recovery latency.
These protocols support live streaming and content distribution without centralized servers. Key approaches include pull-based streaming (Zhang et al., 2007, 230 citations) and large-scale P2P-VoD systems (Huang et al., 2008, 381 citations). Over 1,000 papers address overlay construction, monitoring, and optimization in this area.
Why It Matters
Scalable P2P multicast powers cost-effective video streaming platforms by offloading server bandwidth to peers, as shown in Huang et al. (2008) analysis of large-scale P2P-VoD with reduced server load. Pull-based protocols achieve low latency when server capacity exceeds peer demand several times (Zhang et al., 2007). Locality-aware overlays like mOverlay cut cross-ISP traffic by 50% (Zhang et al., 2004). These enable global content delivery for millions of users without infrastructure costs.
Key Research Challenges
Overlay Stability Under Churn
High peer churn causes frequent tree breaks and recovery delays in multicast topologies. Chen et al. (2004) highlight O(n^2) monitoring overhead in overlays with n hosts. Scalable monitoring requires algebraic gossip methods for sublinear measurements.
Bandwidth Heterogeneity Management
Peers with varying upload capacities disrupt uniform data dissemination in pull-based systems. Zhang et al. (2007) show optimal chunk scheduling counters this when server bandwidth is sufficient. Taxation models address free-riding (Hua-chu et al., 2004).
Locality and Delay Optimization
Random overlays increase latency via cross-domain paths. mOverlay constructs locality-aware structures using stable node IDs (Zhang et al., 2004). Balancing tree branching factor with recovery speed remains unresolved.
