Introduction on Reyee EG Load Balancing Modes and Policies

When multiple links are available, some traffic is forwarded along the link selected based on the address library and the remaining traffic is distributed to other links in load balancing mode.
Reyee EG support 3 load balancing mode：

Load Balancing Mode	Description
Loading balancing	The traffic will be distributed across multiple links according to the weight of each WAN port. Larger traffic will be distributed to the WAN port with a higher weight. When you select this mode, you must specify the weight of each WAN port. For example, if the weight of WAN and WAN 1 ports is set to 3 and 2 respectively, then, 60% of the total traffic will be routed over WAN and 40% over WAN 1.
Active/Secondary	All traffic is routed over the primary interface. Once the primary interface fails, traffic will be switched over to the secondary interface. If there are multiple primary or secondary interfaces, the weight of these interfaces must be set. (See balanced mode.)
Forced Switch	With Load Mode switched from Load balancing to Active/Secondary, if Forced Switch is not selected, traffic of new connections will be routed through the specified primary interface, while the egress for the traffic of existing connections remains unchanged. When Forced Switch is selected, traffic of both new and existing connections will be routed to the primary interface.

We have 4 types of load balancing policies, you can configure based on your needs.

Load Balancing Policy	Description
Based on Connections	After you enable this policy, the traffic is routed over multiple links based on the links. Packets with the same source IP address, destination IP address, source port, destination port, and protocol are routed over the same link.
Based on Src IP Address	After you enable this policy, the traffic is routed over multiple links based on the source IP address. The traffic from the same user (same source IP address) will be routed to the same interface. This policy prevents traffic from the same user from being routed to different links, lowering the risks of network access exceptions.
Based on Src and Dest IP Address	After you enable this policy, the traffic is routed over multiple links based on the source IP address and destination. The traffic of the same source IP address and destination IP address will be routed to the same interface.
Smart Load Balancing	After you enable this feature, the traffic is routed over multiple links based on the link bandwidth, the actual loads of the links, application recognition and traffic prediction.
