Between underlay and overlay

Purpose This paper aims to discuss problems, requirements and current trends for deploying group communication in real‐world scenarios from an integrated perspective. Design/methodology/approach The Hybrid Shared Tree is introduced – a new architecture and routing approach to combine network – and subnetwork‐layer multicast services in end‐system domains with transparent, structured overlays on the inter‐domain level. Findings The paper finds that The Hybrid Shared Tree solution is highly scalable and robust and offers provider‐oriented features to stimulate deployment. Originality/value A straightforward perspective is indicated in the paper for a mobility‐agnostic routing layer for future use
