Advanced Balancing Algorithms

To perform inbound and outbound balancing activities, each Elfiq Link Balancer can use the following seven advanced algorithms to process data. These algorithms can also be used in customized fashions through Traffic Segmentation to meet organizational requirements. The available algorithms are:

• Round Robin: with this algorithm, each link receives traffic an equal number of times, regardless of bandwidth usage.
• Weight First Algorithm: the WFA algorithm gives preference to one link and when the link is saturated to a certain level, the Link Balancer uses another link for traffic distribution
• Least Traffic First Algorithm: the LTFA algorithm will distribute traffic on a set of links based on the level of saturation, where the least saturated will receive new traffic flows.
• Equalized Traffic First Algorithm: the ETFA will distribute traffic equally across a set of links, making sure they are all used with the same amount of traffic continually.
• Weighted and Equalized Traffic First Algorithm: the WETFA algorithm will distribute traffic equally on a set of links and when a defined saturation point is met, one or more additional links will handle future traffic requests
• Ordered Preferred First Algorithm: the OPFA algorithm will distribute sessions based on user-defined preferences in regards to the order in which the links will be used
• Round Robin No-Gmac: the RR-GMAC algorithm is used when redirecting incoming sessions off-site. A GMAC is an link’s (or gateways’s) MAC address, the Elfiq Link Balancers operate for balancing activities under a Layer-2 implementation.
