<abstract>
<t>
   This document combines the idea of address translation described in
   RFC 1631 with real-time load share algorithms to introduce Load Share
   Network Address Translators(or, simply LSNATs). LSNATs would
   transparently offload network load on a single server and distribute
   the load across a pool of servers.

<t>
   Network Address Translators (NATs) translate IP addresses in a
   datagram, transparent to end nodes, while routing the datagram. NATs
   have traditionally been been used to allow private network domains to
   connect to Global networks using as few as one globally unique IP
   address.  In this document, we extend the use of NATs to offer Load
   share feature, where session load can be distributed across a pool of
   servers, instead of directing to a single server.  Load sharing is
   beneficial to service providers and system administrators alike in
   grappling with scalability of servers with increasing session load.
