VPN Tunnel Termination and Load Balancing

Virtual Private Network (VPN) is a widely deployed technology for business to build a secure communication over an IP network between two geographically separate sites. Data security and integrity will be enhanced when VPN solution is in place. It has become one of the most common tools for data security as there is a greater need for encrypting communication than ever before.

In the past, IPSec VPN tunnels destined for the same remote network could only establish over a single interface. IPSec VPN tunnels are traditionally established based on a single Internet circuit. Should the circuit fails, there is no way to keep the continuity for the LAN-to-LAN connectivity. In addition, if more bandwidth is required to accommodate growing demand, this is possibly difficult to achieve through traditional WAN load balancing technology.

However, it is now technically possible to form and send LAN-to-LAN traffic over IPSec VPN tunnels on multiple interfaces with the Q-Balancer Multi-path VPN solution. The VPN tunnels are terminated on the Q-Balancer appliances, and can be either standard IPSec or the Q-Balancer proprietary VPN tunnels.

The Multi-path VPN solution enables LAN-to-LAN traffic to be distributed across multiple WAN links, and it works in conjunction with policy-based routing. This increases the flexibility of traffic control and routing decisions in site-to-site network deployments.

Connectivity – The LAN-to-LAN connectivity stays up and running even if in the event of Internet outage.

Increased Speed – The LAN-to-LAN access is accelerated as it is efficiently distributed across multiple WAN links.

Flexibility – VPN can be deployed anywhere in the world for enterprises, and they get high quality of VPN connectivity even using local Internet providers. The Multi-path VPN tunnel can be built on the WAN transport of any type.

Uncompromised Security – Multi-pah VPN encrypts data through the military-grade encryption, and it provides additional levels of security by sending data packets over multiple WAN links simultaneously.
