Carrier SDN for flexgrid-based inter-datacenter connectivity

A. Asensio, L. Gifre, M. Ruiz, L. Velasco
2014 2014 16th International Conference on Transparent Optical Networks (ICTON)  
Managing inter-datacenter (DC) connectivity to transport increasing amounts of data and optimize DC performance and costs becomes a challenge not only for DC operators but also for network operators.  ...  Current inter-DC connections are configured as static big fat pipes, resulting in large bitrate over-provisioning thus increasing operational costs for DC operators.  ...  Moreover, it was supported by the Spanish science ministry through the TEC2011-27310 ELASTIC project.  ...
