Applicability of BIER Multicast Overlay for Adaptive Streaming Services
               draft-ietf-bier-multicast-http-response-01

Abstract

   HTTP Level multicast, using BIER, is described as a use case in the
   BIER Use cases document.  HTTP Level Multicast is used in today's
   video streaming and delivery services such as HLS, AR/VR etc.,
   generally realized over IP Multicast as well as other use cases such
   as software update delivery.  A realization of "HTTP Multicast" over
   "IP Multicast" is described for the video delivery use case.  IP
   multicast is commonly used for IPTV services.  DVB and BBF is also
   developing a reference architecture for IP Multicast service.  A few
   problems with IPMC, such as waste of transmission bandwidth, increase
   in signaling when there are few users are described.  Realization
   over BIER, through a BIER Multicast Overlay Layer, is described as an
   alternative.  How BIER Multicast Overlay operation improves over IP
   Multicast, such as reduction in signaling, dynamic creation of
   multicast groups to reduce signaling and bandwidth wastage is
   described.  We conclude with few next steps.
