Introduction

Load Balancing is method aiming to spread traffic across multiple links to get better link usage. This can be done one per-packet or per-connection basis.

Method Per-connection Per-packet
Firewall marking Yes Yes
ECMP Yes No
PCC Yes No
Nth Yes Yes
Bonding No Yes
OSPF Yes No
BGP Yes No

Methods

Firewall marking

This method uses firewall packet marking to select one from multiple gateways.

ECMP (Equal Cost Multi-Path)

This method uses multiple gateway with same cost.

PCC (Per Connection Classifier)

Nth

Bonding

Can combine multiple links to get link with higher speed.

OSPF

Two or more links are setup with dynamic routing protocol OSPF with equal cost. Then equal multipath routing is used.

BGP
