2391: Load Sharing using IP Network Address Translation (LSNAT).

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.
