Abstract— Application Layer Multicast (ALM) protocols suffer from delay, throughput and security. To address these all issues, network coding techniques has been introduced. Existing protocols are using either mesh or tree kind of topology structure for data distribution. In these topology structures network coding is too complex. To address this problem, a novel POSET protocol stack has been proposed. It consists of three protocols such as control protocol, poset structure protocol and data distribution protocol. Control protocol controls join, leave and prune operations. Poset protocol forms poset structure using lattices property and distribution protocol consist of finite filed encoding, intermediate encoding and finite field decoding modules. The results have been compared with existing Nice protocol and increases 8.25% of throughput and decreases 33% of delay.

Index Terms— Delay, mesh-tree, security, throughput.
