What is the difference between the 4 Outbound Load Balancing Algorithms?
Round Robin establishes sessions across configured WAN interfaces in a rotating order (similar to a dealer handing out cards at a blackjack table).

Response Time: runs in round robin for a brief time and builds a syn-ack response time sample for each available interface. All sessions thereafter route out the interface with the lowest sample time. A new sample is being taken at around 5 second intervals. If the sample becomes better than the line that has been in use new sessions will be sent out this line. This is ever changing.

Weighted: configures FatPipe {product name} to balance traffic in proportion to the WAN weights defined by you. Each interface needs to be assigned a weight. (Default value for each interface is 1.) The ratio of these weights determines the ratio of download traffic on the respective Internet lines that the load balancing algorithm attempts to maintain. For example, if weights for WAN1, WAN2, WAN3 are 1, 2, 3, respectively, and total download traffic amounts to 600kbps, the traffic will be balanced over respective lines as 100, 200, 300 kbps. Because FatPipe balances sessions rather than packets, real world results will rarely achieve this ideal. In general, the greater the number of sessions, the closer the distribution of traffic will be to the specified weights.

Fastest route: Multiple copies of the SYN packet are sent from all available interfaces. The interface on which the first SYN-ACK packet returns, wins the session.
