Abstract
This document specifies Multi-Stage Transparent Server Load Balancing
(MSLB) specification. MSLB make server load balancing over Layer3
network without packet header change at client and server. MSLB make
server load balancing with any protocol and protocol with encription
such as IPsec ESP, SSL/TLS.

Internet-Draft MSLB March 2017
1. Introduction
This document specifies Multi-Stage Transparent Server Load Balancing
(MSLB) specification.
MSLB provide server load balancing function over Layer3 network
without packet header change at client and server. MSLB work with
any protocol and protocol with payload encription such as IPsec ESP,
SSL/TLS.
2. Traditional load balancing method
There are several load balancing technique, such as round robin DNS,
IP Anycasting [RFC1546] and destination address translation.
Figure 1 shows load balancing system with typical server load
balancer with destination address translation technique.
