Towards a carrier SDN: an example for elastic inter-datacenter connectivity

L. Velasco, A. Asensio, J.L. Berral, A. Castro, V. López
2013 Optics Express  
We propose a network-driven transfer mode for cloud operations in a step towards a carrier SDN. Inter-datacenter connectivity is requested in terms of volume of data and completion time.  ...  The SDN controller translates and forwards requests to an active PCE controlling a flexgrid network.  ...  Once the set of VM to be migrated and DB synchronization needs are determined, cloud management performs those operations in collaboration with inter-and intra-DC networks.  ...
