MPLS Internet Breakout

Over the last 10 years, VPN providers have been encouraging companies to have single breakout points to the Internet.

This has been seen as beneficial, because it gives the company only a single point of risk to Internet exposure, and the aggregation value of only one Internet breakout is more economical.

But this isn’t actually the best business solution

There are some serious drawbacks to an aggregated breakout solution:

  • Companies using an aggregated Internet breakout are using expensive MPLS bandwidth to get to the Internet.
    It’s completely uneconomical, because you are paying expensive MPLS fees, only to get to a best-effort Internet service. This in most cases works out to be double what you would pay just to get to the Internet.
  • It has a detrimental impact on your network performance, as Internet is always competing with your business-critical applications and services like voice.
  • A further problem arises when companies are using ADSL for small branches and trying to send Internet and MPLS type data through a link that has a limited uplink speed.

That’s why EOH offers regional Internet breakouts

Our approach to Internet breakout from MPLS is to provide a range of strategies around reducing MPLS fees, by breaking Internet out of the network regionally or at a branch level.

In most large networks there could - or should - be three regional Internet points: JHB, CPT and DBN. This will ensure that most regional traffic flowing across the network will be restricted to critical business applications.

There is also a minimal effect on security, as you have a carbon copy security standard for each breakout, which provides no less security than one breakout.

This gives your company measurable cost reductions and quality improvements

In smaller branches where ADSL is the last mile, EOH provides a dedicated ADSL to MPLS solution using a dedicated Telkom IP connect service. This is generally restricted to the uplink size of the service as MPLS is a full duplex type of service, whereas ADSL is asymmetrical.

We then put a Per Gig or uncapped ADSL service directly on the ADSL, which uses the remaining downlink capacity to deliver Internet directly to the branch at a faster speed than the MPLS could - and at a lower cost.

In this way we improve services delivery in the MPLS network, increase Internet speeds by delivering directly to the branch, and reduce cost.
