The LIGHTNESS intra-DCN solution, based on a hybrid all-optical OCS/OPS architecture, aims to overcome such limitations, providing an architecture suitable for the management of both long- and short-lived traffic flows. In this paper, we evaluate the performance of such a hybrid architecture in terms of blocking probability for various traffic conditions, highlighting its benefits against pure OCS or OPS networks.Peer ReviewedPostprint (author's final draft) Open Access Àrees temàtiques de la UPC::Enginyeria de la telecomunicació::Telecomunicació òptica Computer networks -- Design and construction Data processing service centers Telecommunication -- Traffic -- Management intra-DCNs OPS OCS.
