Efficient multicast delivery in a spot beam high-throughput and very high-throughput satellite network

Abstract

IP multicast service provides an efficient way to deliver content from one node to multiple nodes. Satellite communication on the forward link is inherently broadcasted, ensuring access to many devices in remote areas. The satellite systems are expected to take a game-changing role in the development of the Internet of Things (IoT) and Mobile Edge Caching (MEC) sectors by providing efficient multicast content delivery schemes. However, in a multi-user, multi-spot beam High-Throughput Satellite (HTS) or Very High-Throughput Satellite (VHTS), several strategies and adaptations are required for integrating multicast networks with a satellite communication system for efficiency and reliability. Many techniques are discussed here, including efficient link adaptation for multicast flows, an adaptation of multicast control protocols over space link, and the provision of necessary ground system designs to support beam multicast capability on next-generation reconfigurable payload satellites. An elegant approach for multicast support in a wholesaler/reseller network is suggested to allow for services from different operators through the same IPv4/IPv6 multicast address. A group key-based scalable conditional access system is proposed. A technique is captured that converts the plurality of live HTTP unicast video streams of the same event to a multicast stream for a resource-efficient transport over the satellite.
