Will MPLS++ Delay the Need for IPv6 ? Consumers will be able to subscribe to Virtual IPv4 Internets. KIDS on one and XXX on another. PBS may be in the middle.
IPv4 experts & IPv6 advocates certainly understand that Bloat & Bandwidth are factors to consider in networks. MPLS adds 32-bit Labels BEFORE an IP packet. A simplified Label is 24-bits with 4 Symbols and an 8-bit TTL. With the extra TTL the IPv4 TTL becomes less critical offering more bits for expansion. http://tools.ietf.org/html/rfc3032 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Label | Label | TTL | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Label Alphabet: 0-9 A-Z a@ b♠ c© d♦ e= f☺ g& h# i| j♫ k♣ l( m₪ n! o* p% q♥ r) s$ t~ u_ v^ w? x☼ y¥ z▒ -™ .® ~ 6 bits per Symbol ~ 64 Symbols _______________________________________________ Nanog-futures mailing list [email protected] https://mailman.nanog.org/mailman/listinfo/nanog-futures
