A network service is composed of an ordered sequence of VNFs, i.e., VNF Forwarding Graph (VNFFG), deployed across distributed data centers (DCs). Herein, we present a Cloud/Network Orchestrator which dynamically processes and accommodates VNFFG requests over a pool of DCs interconnected by a multi-layer (packet/flexi-grid optical) transport network infrastructure. We propose two different cloud and network resource allocation algorithms aiming at: (i) minimizing the distance between the selected DCs, and (ii) minimizing the load (i.e., consumed cloud resources) of the chosen DCs. Both algorithms run on a Cloud/Network Orchestrator and are experimentally validated and benchmarked on the CTTC ADRENALINE testbed. %G English %Z TC 6 %Z WG 6.10 %2 https://inria.hal.science/hal-03200646/document %2 https://inria.hal.science/hal-03200646/file/484327_1_En_23_Chapter.pdf %L hal-03200646 %U https://inria.hal.science/hal-03200646 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC6 %~ IFIP-LNCS-11616 %~ IFIP-ONDM %~ IFIP-WG6-10
