Algorithm

Weighted Round Robin - Each member interface is assigned a weight. An

 

 

interface with a larger weight gets more chances to transmit traffic than an interface

 

 

with a smaller weight. For example, if the weight ratio of wan1 and wan2 interfaces

 

 

is 2:1, the ZyWALL chooses wan1 for 2 sessions’ traffic and wan2 for 1 session’s

 

 

traffic in each round of 3 new sessions.

 

 

Least Connection - The ZyWALL chooses choose a member interface which is

 

 

handling the least number of sessions.

 

 

Least Load - Outbound - The ZyWALL chooses a member interface which is

 

 

handling the least amount of outgoing traffic.

 

 

Least Load - Inbound - The ZyWALL chooses a member interface which is

 

 

handling the least amount of incoming traffic.

 

 

Least Load - Total - The ZyWALL chooses a member interface which is handling

 

 

the least amount of outgoing and incoming traffic.
