                        draft-matsuhira-mslb-04

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.

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.
