While most people are getting excited about ‘cloud’ there are multi-billion dollar businesses working on upgrading their networks to early-2000’s level technology.
This proposed standard complexifies a carrier network to a whole new level. I understand that some carriers are delivering legacy video over their networks with IPv4 Multicast, but wow, keeping this running and finding high quality software apps won’t be a fun place to work.
This document specifies a solution for the delivery of IPv4 multicast services to IPv4 clients over an IPv6 multicast network. The solution relies upon a stateless IPv4-in-IPv6 encapsulation scheme and uses an IPv6 multicast distribution tree to deliver IPv4 multicast traffic. The solution is particularly useful for the delivery of multicast service offerings to customers serviced by Dual-Stack Lite (DS-Lite).
Some people networks are making money out of this stuff. I can’t imagine how much it costs to support the inherent complexity.
