The evolution of multicast in the network slices era

The article is organized as follows.

The first chapter recalls some basic concepts of transmission modes and multicast networks. It also recalls the concept of the "slice", which has been revived with the publication of specifications for 5th generation mobile networks (5G networks). Finally, it describes the problems generated by the use of network slices to carry multicast traffic characteristic of broadcast services, both in terms of quality of service and traffic classification rules.

The second chapter describes the engineering principles for optimizing the use of network slices designed to carry multicast traffic, as well as the quality of broadcast services based on the deployment of multicast slices within a network.

The third chapter details the use of techniques such as multicast signaling and routing protocols, as well as Service Function Chaining (SFC), to optimize the deployment and operation of broadcast services on a network supporting multicast slices.

Finally, the article concludes with a discussion of future prospects, taking into account advances in research in this field.
