Simple & Effective Broadband Failover

Dont get caught out!

Don't get caught out...

Your business relies on its Internet connection. As Internet connectivity becomes more essential for your business, losing it, even for a brief period can be a real problem. No Internet means no email, no web browsing and in many cases, no work. What happens in your business when the Internet is down. No email, no incoming orders, no web browsing, no news or market feeds. Every business is different, but if you rely on the Internet, hoping for the best is probably not the best plan.

ISPs don't offer an 'SLA' (reliability agreement/guarantee) on VDSL/ADSL lines and even if yours does, that can't actually guarantee that your line will always work, and can always be fixed immediately. A line fault, ISP maintenance, ISP routing failure, cable damage, power failures at the ISP or exchange - all of these can break your connection - for a short time, or even for days.

What would happen if it fails for a brief period or even an extended period during the day.

What impact will that have on your efficiency, productivity and your business in general?

DrayTek routers not only provide a vast array of security and connectivity features, they have secondary connections for an alternative (backup) Internet connection.

For example, with a Vigor 2865 VDSL Router/Firewall, your primary feed would be VDSL2. In the event of that failing, the Vigor 2865 will automatically switch over to one of the following:

  • A second xDSL line, using a separate DSL modem (such as the Vigor 166) and different ISP
  • 4G / LTE Mobile Broadband (e.g. BT/EE, O2, Three, Vodafone etc.), either via Integrated LTE or USB modem
  • Fibre or Cable-Modem service (e.g. VirginMedia)
  • Any nearby Wireless network, including a mobile phone's Mobile Hotspot. Using the router's Wireless WAN mode
  • Any other Internet connection, through an Ethernet cable

Once your primary (main) broadband service is restored, the router again automatically switches back to that. As well as failover mode, when both connections are available, the router can use both at the same time to provide more total Internet bandwidth to your network.

Most DrayTek routers support failover to a second Internet connection; the exact model will depend on your line type and the number of feeds required. Some DrayTek routers also support VPN trunking, whereby the second WAN connection can be used for VPN backup and to increase the total VPN tunnel bandwidth.

Load Balancing

When not being used for failover, many DrayTek products can use the second internet connectivity simultaneously with your first for 'load balancing' which increases your total Internet bandwidth. Load balancing either automatically spreads your internet traffic across both connections, or you set rules for specific traffic or users to use specific connections.

Example 1 : Using a second ADSL/VDSL line

Example 2 : Using a VDSL + 4G/LTE router

Hopefully, your broadband service is reliable most of the time. Even if you've never had a problem, allowing for one gives you peace of mind that you will be able to cope.
