Bonded VPN Bonding and Load Balancing

Thinking of deploying a bonded VPN?

Virtual Private Networks form a major part of many organisations' network infrastructure. They are often used as a vehicle to serve sensitive information to remote offices and workers. Typically VPN's are created point-to-point making it difficult to add any resilience or more bandwidth. Introducing our products to this infrastructure makes this possible, whether you are implementing new or expanding existing VPN infrastructure.

Traditional VPN's both client and site-to-site are based upon a single Internet link. Should this link fail, organisations invariably have no fall-back plan, and simply have to diagnose, report and wait.

Should an organisation require more bandwidth to accommodate increasing demand, this is often proves difficult and is some cases impossible. This could mean expensive upgrades, change of ISP and most likely their complete Internet infrastructure.

SME's generally use DSL to serve their VPN connections. This can cause considerable bottlenecks and can prevent service being offered to clients should demand outgrow the supply. VPN Load Balancing provides a scalable solution to organisations with the capability of aggregating up to a maximum of 32 Internet connections. As requirements grow an organisation can simply add extra Internet connections to the UBM appliance.

Another issue is that traffic distribution is done "by packet" and so a single data connection can assume all the available bandwidth. This could be a VoIP call over Teleconferencing. With multiple connections, a VPN Load balancing allows organisations to have a dedicated Internet connection for specific applications such as VoIP to ensure a continuous service.

With the UBM’s VPN Load balancing solution, should any active Internet connection fail, data is simply retransmitted down other available connections with no impact to the client.
