> Sliding window protocols use finite sequence numbers to determine
> segment placement and order. These sequence number spaces wrap around
> and are reused during the operation of such protocols. This document
> describes a way to extend the size of these sequence numbers at the
> endpoints to avoid the impact of that wrap and reuse without
> transmitting additional information in the packet header. The
> resulting extended sequence numbers can be used at the endpoints in
> encryption and authentication algorithms to ensure input bit patterns
> do not repeat over the lifetime of a connection.
