POSET: A high-performance application layer multicast protocol design and implementation

Many research issues have been raised in Application Layer Multicasting (ALM), such as group management, security, integrity of data, link stress, link stretch, load balancing, fault tolerance and scalability, because of the shifting of the multicast protocol from the IP layer to the application layer. To address these issues many protocols have evolved by changing their topology structure. In this paper, the POSET protocol stack is proposed, which consists of three layers, such as communication control, POSET cube, and content distribution. The novelty of this paper is the lattice-based data distribution with POSET cube architecture. The results have been compared with the existing NICE and Narada protocols. The experimental results show that the proposed POSET protocol improves throughput between 7.14% and 40% and decreases the delay between 7.69% and 25%, compared to the existing NICE protocol.
