VPN Bonding & Failover

Large files and applications such as VoIP and Video Conferencing are frequently transmitted in site-to-site VPN networks, which are usually connected via leased line or MPLS or VPN. Ensuring mission-critical applications to be allocated with enough bandwidth and to gain uninterrupted connectivity in site-to-site networks is a major task for IT department.

VPN and leased line networks are traditionally established based on a single Internet circuit. Should the circuit fails, there is no way to keep the continuity for the organizations. In addition, if more bandwidth is required to accommodate growing demand, this is possibly difficult to achieve through traditional WAN load balancing technology. This could mean expensive upgrades or change for legacy WAN infrastructure.

Our XBond bandwidth bonding technology is able to work on static IP, dynamic IP, and even private IP, and can be integrated into existing VPN networks with minimal impact. In the event of an Internet line fails in a site-to-site VPN network, XBond will still keep VPN connectivity up and running by sending traffic down to the remaining active line. The technology also maximizes site-to-site WAN capacity by efficiently bonding multiple Internet lines at sites.
