There are a number of solutions on the market today that perform link balanincg, however these products lack the ability to actually fully utilize each available WAN interface. Only the patented bonding technology by XRoads Networks supports the aility to combine two or more ISP connections for a single session, example a 3Mbps link can be combined with a 5Mbps link to obtain a true 8Mbps session download.
Internet link bonding works by combining multiple Internet connections for every individual session, thus with a 3Mbps link and a 5Mbps link a single session download can each 8Mbps in performance. The EdgeXOS platform is smart enough to know which traffic it can bond and which traffic must maintain session persistence and does this automatically.
Notice in the example of link bonding above that a single session 'blue' is split in to multiple sessions out each Internet connection to the same remote server, this significantly increases the speed of accessing remote files and/or sites.
Link load balancing works by balancing sessions across different Internet connections, thus one session might go out the 3Mbps link and another session might go out the 5Mbps link but this technology does not have the ability to combine the links for the same session. With simple link load balancing users will never be able to bond the speeds of each Internet connection.
In this example of link load balancing each session is routed out different links, but a single session can not be combined, thus the additional performance provided by link bonding can not be achieved with simple load balancing.
