Table 34 Load Balancing: Least Load First (continued)

 

LABEL

DESCRIPTION

 

Time Frame

You can set the ZyWALL to get the measured bandwidth using the average

 

 

bandwidth in the specified time interval.

 

 

Enter the time interval between 10 and 600 seconds.

 

 

 

 

Load Balancing

Specify the direction of the traffic utilization you want the ZyWALL to use in

 

Index(es)

calculating the load balancing index.

 

 

Select Outbound Only, Inbound Only or Outbound + Inbound.

 

 

 

 

Interface

This field displays the name of the WAN interface (WAN 1 and WAN 2).

 

 

 

 

Available

This field is applicable when you select Outbound + Inbound or Inbound Only in

 

Inbound

the Load Balancing Index(es) field.

 

Bandwidth

Specify the inbound (or downstream) bandwidth (in kilo bites per second) for the

 

 

interface. This should be the actual downstream bandwidth that your ISP provides.

 

 

 

 

Available

This field is applicable when you select Outbound + Inbound or Outbound Only in

 

Outbound

the Load Balancing Index(es) field.

 

Bandwidth

Specify the outbound (or upstream) bandwidth (in kilo bites per second) for the

 

 

interface. This should be the actual upstream bandwidth that your ISP provides.

 

 

 

8.8.2 Weighted Round Robin

To load balance using the weighted round robin method, select Weighted Round Robin in the Load Balancing Algorithm field.

DESCRIPTION

Active/Active

Select Active/Active Mode and set the related fields to enable load balancing on the

Mode

ZyWALL.

 

 

Load Balancing

Set the load balancing method to Weighted Round Robin.

Algorithm

 

 

 

WAN Interface

Select this option to have the ZyWALL send all of a local computer’s traffic through

to Local Host

the same WAN interface for the period of time that you specify (1 to 600 seconds).

Mapping

This is useful when a redirect server forwards a local user’s request for a file and

Timeout

informs the file server that a particular WAN IP address is requesting the file. If the

 

user’s subsequent sessions came from a different WAN IP address, the file server

 

would deny the request.
