It would have been better if IETF had actually solved this instead of punting on it when developing IPv6.
Dear Owen, The IETF offered a HA solution that operates at the transport level. It solves jumbo frame error detection rate issues, head of queue blocking, instant fail-over, better supports high data rates with lower overhead, offers multi-homing transparently across multiple providers, offers fast setup and anti-packet source spoofing. The transport is SCTP, used by every cellular tower and for media distribution. This transport's improved error detection is now supported in hardware by current network adapters and processors. Conversely, TCP suffers from high undetected stuck bit errors, head of queue blocking, complex multi-homing, slow setup, high process overhead and is prone to source spoofing. It seems OS vendors rather than the IETF hampered progress in this area. Why band-aid on a solved problem? Regards, Douglas Otis
