Benefits of active stateful PCE for flexgrid networks
, 2014 Relevant benefits of the active stateful PCE architecture are experimentally demonstrated on a flexgrid network testbed. Two experiments are reported, including a first demo on PCE-controlled code-adaptation applied to a 1Tb/s super-channel.

Incremental capacity planning in flexgrid optical networks
, 2015 Les xarxes de comunicacions de fibra òptica necessiten adaptar-se com a resposta a l'evolució del tràfic de dades que han de transportar. Aquesta evolució inclou l'extensió periòdica de la seva capacitat per tal de millorar alguna de les mètriques que caracteritzen el seu funcionament, com per exemple la capacitat de restaurar la connectivitat del ...

Optimization models for flexgrid elastic optical networks
In the paper we present integer programming (IP) optimization models for flexgrid elastic optical networks (EON). We consider several different basic assumptions regarding flexibility of EON that lead to a variety of IP formulations differing in ...

Inter-Datacenter Connectivity in Flexgrid-based Optical Networks
, 2014 The huge energy consumption of datacenters (DC) requires an elastic resource management, e.g. by turning servers off when they are not used or turning them on to satisfy increments in the demand. Thanks to virtualization, jobs (e.g., web applications) can be encapsulated in virtual machines (VM) mixed with other workloads and consolidate them in the ...
