How to take control of your VPN performance - part 2

In my last post, I have talked about applying broadband bonding technology to improve inter-office VPN performance (Virtual Private Network performance) by increasing available throughput and by boosting reliability.

Once you have taken care of the transport, you still need to make sure to available IP connectivity is indeed “oiled” well for the applications you care about, in our case, the VPN traffic for top level VPN performance.

It is very common to have non-VPN traffic to dominate the transport resources and starve VPN traffic in the meantime if QoS (Quality of Service) is not setup correctly. In today’s networks, not all applications are TCP friendly and therefore can consume an unfair share of the network, which will hit the VPN performance and will bring some of the interactive applications to its knees and as a result will bring the end-users to their knees praying for better QoS.

Broadband Bonding routers equipped with advanced QoS functionality is essential. By carving out guaranteed bandwidth for your VPN traffic while limiting the other traffic will provide the much needed breathing room for the applications utilizing the VPN tunnel. If the broadband bonding router supports dynamic QoS, then the applications that are traffic shaped will still have the bandwidth at their disposal during times where VPN traffic is low or non-existent. As soon as VPN traffic is detected, all other traffic, will be traffic-shaped.

This two legged approach by one: adding speed and reliability to your transport and two: controlling the traffic within that transport, will provide the optimal VPN performance.

There are two types of VPN available in the market. Browser-based VP which only change the route of your browser leaving any other software to the same IP and system based VPN that changes the route of the systems IP. You can control the VPN settings on your own and change the routing address by yourself.
