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 HTTP Live Streaming
(HLS), Augmented Reality and Virtual Reality(AR/VR), 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. Digital Video
Broadcasting (DVB) and Broadband Forum (BBF) also develope a
reference architecture for IP Multicast service. A few problems with
IP Multicast, 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 a few next steps.
