Virtual Leased Line is the most comprehensive comBOX service. It effectively aggregates the bandwidth of the available conventional connections in both upstream and downstream and it creates a virtual leased line for all kinds of traffic from and to the Internet. The aggregate bandwidth is available for use both by the local users (web browsing, ftp browsing, sending/receiving emails, etc) and by the remote users who use locally hosted online services (eg Web server, FTP server, Mail server, VPN server etc).

The Virtual Leased Line service routes all traffic through a dedicated server located in a high-speed data-center within the EU. A new static IP address is provided for use by remote users who wish to connect to locally hosted servers. More than one IP address can be provided for more complex use cases.

The implementation of Virtual Leased Line effectively aggregates all the available bandwidth in order to achieve high data rates in both directions. Consequently, it is possible to achieve upload rates that would require a leased line, while download rates can easily overcome ADSL's hard limit of 24Mbps.

By carefully selecting the providers of the conventional connections, it is possible to maximize the availability of the service since in the event of a sub-connection that stops responding, it will automatically be isolated and no downtime will occur for the Virtual Leased Line. The only implication during such events will be the temporary reduction of the overall available bandwidth by the rate the malfunctioning connection contributed, until it resumes functioning.

Thanks to using low-cost Internet resources, the Virtual Leased Line service creates aggregate connections that can reduce Internet connectivity costs up to 50% compared to the respective leased line solutions. Moreover, when using asymmetric sub-connections (eg ADSL), the achieved download rates are multiples of the ones achieved by symmetric leased lines.

Conclusively, the Virtual Leased Line service gives businesses who want to avoid overpriced leased lines the chance to enjoy Internet connections with even better characteristics. Besides, businesses who already use leased line solutions can reduce networking expenses immediately and improve their connectivity at the same time.
