4.1.4 WAN Traffic
DSA-3600 supports uplink/downlink bandwidth management and WAN Failover features, including WAN Failover,
Load Balancing and Connection Detection features.
Available Bandwidth on WAN Interface:
y
Uplink:
It defines the maximum uplink bandwidth allowed to share by clients within WAN interface.
y
Downlink:
It defines the maximum downlink bandwidth allowed to share by clients within WAN interface.
WAN Failover & Connection Detection:
The DSA-3600 supports WAN Failover, Load Balancing feature and the
ability to detect WAN connection.
y
Target for detecting Internet connection:
To verify the connection to the Internet, the system keeps up to
three Target IP or Domain Name. These targets are used for the system as the detected targets of
Enable Load
Balancing
and
Warning of Internet Disconnection
. To enable WAN Failover, at least one target must be
configured.
y
Enable Load Balancing:
Check this option to active the system’s load balance function. System will allot all
traffic to WAN1 and WAN2 by the weight radio. The weight radio between WAN1 and WAN2 can be based on
Sessions, Packets or Bytes.
¾
WAN1 Weight:
Enter value range between 1~99. The default is 50.
¾
Base:
Three bases of the Load Balancing ratio are supported,
session
,
packet
, and
byte
. Packet and Byte
are based on historic downlink data. New connection sessions will be distributed between WAN1 and WAN2
by a weight ratio using random number.
ƒ Limitation:
o
DMZ hosts will be excluded from WAN Load Balancing.
o
SIP authentication is excluded from WAN Load Balancing.
