Poll results: Internet traffic transport options

I was somewhat surprised by the results of my recent “Do you use MPLS to transport Internet traffic?” poll. I had assumed that most Service Provider networks today use MPLS-based BGP-free core, but almost half of the respondents transport Internet traffic natively.

Obviously you have to take the results with a grain of salt:

  • We can’t be sure that all respondents are indeed Service Providers; most enterprise users obviously transport Internet traffic natively.
  • In a democratic poll like this one, an engineer operating a small network with a few routers (where you can have a small default-free part running BGP) and an engineer working with a huge global network get one vote each.
  • Last but not least, as Bad designer pointed out, the four options you had are not exclusive; if your network is large enough, you could use different mechanisms in different parts of your network.

Anyhow, regardless of what you use, all four design options are covered in my Building IPv6 Service Provider core webinar (register here).
