Link aggregation combines two or more Internet connections and provides Internet-based applications access to the total available combined bandwidth. Most link aggregation techniques support link load balancing to route Internet sessions from congested links, to links with more available bandwidth. They also provide automatic failover of Internet sessions from failed links to functional connections to eliminate a single point of failure. For example, if you have a T1 line (1.5 Mbps) and need additional bandwidth, you would typically have to upgrade to a T3 line (45 Mbps). However, this is more than likely significantly more bandwidth than is required, and is a dramatic increase in cost.

With Ecessa ’s PowerLink™, this same scenario can be accomplished with two 768 Kbps DSL lines that can be combined for a total aggregated bandwidth equivalent to a T1 line - at a fraction of the cost. You can also add additional lower speed lines such as xDSL, cable, wireless etc., with a relatively small increase in cost that can more closely matching your needs. In addition to getting more cost-effective bandwidth, you are also dramatically increasing the reliability of your connection due to the new levels of redundancy through the aggregated Internet connections. PowerLink is independent of WAN technologies, and is fully compatible with xDSL, cable, wireless, T1, E1, T3, E3, satellite, fiber channel, Frame Relay, etc. You can mix and match to best fit your needs. The total bandwidth aggregation capacity of PowerLink allows for up to 500 Mbps, and will accept up to 15 different WAN connections. Further, the PowerLink has the ability to host up to 500 domain names with up to 128 hosts per domain name.
