Load Balancing is methology with aim to spread traffic across multiple links. This can be done one per-packet or per-connection basis.
Methods
Firewall marking
This method use firewall packet marking to select one from multiple gateways.

- Load Balancing over Multiple Gateways

ECMP (Equal Cost Multi-Path)
This method use multiple gateway with same cost.
PCC (Per Connection Classifier)
Nth
- NTH load balancing with masquerade
- NTH load balancing with masquerade (another approach)

- Manual:NTH in RouterOS 3.x
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.
