Background

SURFnet6

Hybrid

  • IP: packet-switched
  • Lightpaths: circuit-switched (with Quality of Service)

Ethernet

Packet-switched (LAN) Carrier ethernet (MAN)

New ethernet extensions

Provider Backbone Bridges (PBB) Provider Backbone Transport (PBT)

Research Question

“In which way(s) are SURFnet's customers able to setup an end-to-end connection through SURFnet6 and their

  • wn internal ethernet network, with use of the new

ethernet extensions Provider Backbone Bridges (PBB) and Provider Backbone Transport (PBT)?”

Conclusion

Protocols are described in our report

Many articles about PBT online, often first

drafts or management summary

SURFnets customers can implement PBT

By enabling PBT on at least two bridges, or by placing at least two Edge Bridges
