How to take control of your VPN performance

Managing VPN performance is important for an organization because of the increasing demand of the applications running within that VPN tunnel. Many critical applications (think VoIP and “as-a-Service” offerings) are now cloud based, so when a branch office is connected to the headquarters (HQ) office or a private cloud data center, that VPN tunnel performance dictates the effectiveness and efficiency of that office. So when the VPN performance deteriorates, it brings down the whole effectiveness of that branch office.

Usually the major factor that impacts VPN performance is the IP connectivity between the branch and the HQ office. This inherent risk factor on the VPN performance is much exacerbated if the organization depends on a single ISP (Internet Service Provider). Any fluctuation of that single ISP link in terms of available throughput, latency metrics or a direct connectivity issue will create VPN performance problems.

One effective way to eliminate this high-cost risk is to leverage several ISP links and intelligently combine them to increase the VPN performance both in terms of sheer speed as well as reliability. The idea is to use broadband bonding routers at the branch office and at the HQ office that will create an overlay bonded tunnel between the offices. This enables VPN traffic to be intelligently transferred over all the available links simultaneously and therefore improves VPN performance. This also creates session continuity which protects the VPN against any line failures even during a transmission.

The first step in taking control of your VPN performance means taking control of your WAN connectivity via technologies such as packet-level load balancing (broadband bonding).

In my next post, I will discuss how taking control of your applications within your VPN is also crucial for optimal VPN performance. Stay tuned for part 2
