Why 3168 is special

It lets a router signal congestion by marking a packet rather than dropping it, and deployment stalled for years because middleboxes discarded the marked packets.

Technology & computing

  • RFC 3168 specifies ECN, adding IP and TCP fields so congestion can be indicated by marking rather than loss. Middlebox interference delayed deployment substantially.
