Outbound Link Load Balancing
For Outbound LLB, the system can intelligently oute and dynamically adjust the traffic load of each link by monitoring the delay, jitter, packet loss rate and bandwidth utilization of each link in real-time.You can configure a flexible LLB profile to bind to the route (the current system only supports DBR and PBR), forming LLB rules to implement outbound dynamic link load balancing, and thus make efficient use of network bandwidth.
Configuring LLB Profile
The LLB profile contains the parameters of the load balancing algorithm, such as bandwidth utilization threshold, probe switch, probe mode, and equalization direction.
- Select Network > Outbound > Profile.
In the LLB Profile Configuration page, configure as follows:
Option Description Profile Name Specifies the Profile name whose length range is 1-96 characters. Bandwidth
Specifies the bandwidth utilization threshold of the interface. When the rate does not exceed the threshold by the interface bandwidth, the system will only analysis delay, jitter and packet loss rate to dynamically adjust the routing link; when the rate exceeds the threshold by the interface bandwidth, system will analysis of each link bandwidth utilization rate of the parameters at the same time to adjust the routing method. Value ranges from 0 to 100 (0% to 100%) and defaults to 60. Balance Mode There are two equalization modes: High Performance and High Compatibility.
- High Performance - In this mode, system adjusts link to keep the link balance as fast as possible
- High Compatibility - When the link load changes, system does not switch the link frequently, but ensures that the service is as far as possible on the previous link. This mode is suitable for services that are sensitive to link switching, such as banking services, only when the previous link is overloaded.

- Click OK.
Configuring LLB Rule
The LLB Profile and the route is bound by the formation of LLB rules that currently support binding destination routing (DBR) and policy-based routing (PBR).
- Select Network > Outbound > Rule.
In the LLB Policy Configuration page, configure the following:
Option Description Rule Name Specifies the Rule name, length of 1-96 characters LLB Profile Specifies the bandwidth utilization threshold. It is in the range of 0-100 (0% -100%) and defaults to 60. Bind Route Specify the route to be bound in the rule: Destination Route or Policy Based Route.
- Destination Route - When this option is selected, specify the virtual router and destination address of the destination route.
- Policy Based Routing - Select this option to specify the name and id of the policy route.
- Click OK.
