TLDR
In this paper, some network topologies for such a pan-European fiber-optic backbone network are presented and a distinction is made between different recovery options in the optical layer for the different traffic types considered.Abstract:
The traffic to be carried by today's European backbone networks increases very rapidly. An important portion of this traffic consists of data traffic (mainly IP-related). In the future data traffic is expected to become the abundantly dominant traffic type, while voice traffic will only account for a very small portion of the total traffic volume. In this paper, some network topologies for such a pan-European fiber-optic backbone network are presented (more details can be found in [1]). These topologies are compared in terms of the efficiency of the network design both from a cost and capacity point of view and in terms of the availability of the connections routed over this network. In order to be able to assess the network topologies under realistic circumstances, the expected traffic demand is forecasted. This enables to make the comparison for the current traffic volume as well as for the traffic patterns of the future. As not all types of (data) traffic require the same degree of survivability and in order to leverage the total capacity cost of the network design, a distinction is made between different recovery options in the optical layer for the different traffic types considered.read more

OpenFlow: Meeting carrier-grade recovery requirements
TL;DR: This paper adds the recovery action in the switches themselves so that the switches can do recovery without contacting the controller, and shows that this approach can achieve recovery within 50ms in a large-scale network serving many flows.

TL;DR: The European network has 28 nodes and is therefore the largest network, while the German network (17 nodes) and the US network (14 nodes) have about the same number of nodes and links.
