OMB: IPv6 by June 2008

Wed Jul 13 01:21:05 UTC 2005

> With G.711 and 20ms voice samples, with IPv4 you get:
> 
> 20 bytes IP + 8 bytes UDP + 12 bytes RTP + 160 bytes payload
> 20% overhead.

> Now with IPv6. Say we use shim6 or something like that to implement

> 40 bytes IP + 32 bytes shim6 8 bytes UDP + 12 bytes RTP +
> 160 bytes payload
> 36.5% overhead

hey!  we charge by the byte.  so ipv6 is looking better and better!
