Load Balanced DSL is the basic comBOX service. It takes advantage of multiple low-cost Internet connections to improve connection availability and the overall available bandwidth by distributing network traffic.

The failover feature of the Load Balanced DSL service detects malfunctioning connections, isolates them and keeps using only the properly functioning ones. This way, local area network users continue to use the Internet without experiencing any downtime.

Local area network users also experience an improvement of the overall Internet connection speed both upstream and downstream since each new HTTP/TCP/UDP connection is routed through a different ADSL connection in a round robin manner.

The use of DNS load balancing techniques can even distribute traffic related to locally hosted servers between the available ADSL connections in order to improve the availability and capacity of the servers.

The software running on the comBOX equipment used by Load Balanced DSL can be easily upgraded to provide a range of additional functionalities such as firewall, VPN, Layer 7 filtering, HTTP Proxy, QoS and traffic shaping. Moreover, all the other services of the comBOX suite use the same equipment and an upgrade to any of them can be carried out swiftly and inexpensively.

The improved Internet connection reliability offered by Load Balanced DSL is based on using heterogeneous Internet resources. Selecting different providers for each sub-connection minimizes the chances of simultaneous connection failures and ensures uninterrupted connectivity. For extremely critical applications, using a combination of wired and wireless (eg 3G/HSPA/VSAT) Internet connection resources is suggested. This way connectivity can be retained even in the unfortunate case of a complete wired network breakdown.

Load Balanced DSL offers a cost-effective solution to the problem of unreliable ADSL connections provided by some ISPs. Besides, it can relieve Internet connection congestion problems, common in multi-user local area networks.
