Multicast - the Sleeping Giant
It has been said, by more than a few of my close friends, that I can talk endlessly about IP multicast. It has fascinated me since I first heard of it back in the mid-1990s. My exposure has been pretty deep.
In the early pages of this book - Section 1.2 to be exact - I touched on some of the early factors that piqued my interest. But I want to take a voyage into multicast and, looking into the crystal ball, more specifically focus around what I think IP multicast can bring, and how tantalizingly near with the technology, yet so far culturally we are from bringing that to be possible.
Multicast came about when Steve Deering - lead designer of IPv6 - postulated IP multicast extensions in the IETF RFC966.
This is not the right book for a detailed breakdown of IP and IP classes, so I will either assume you know or can otherwise research this elsewhere. Here I want to try to create a simple picture of multicast and, more important, the challenges it faces in technical deployment for a CDN.
