Cross-Functional resource orchestration in optical telco clouds

With communication endpoints given by mobile user devices and by elastically provisioned virtual resources, one of the main challenge of cloud-based service provisioning is to deploy a coordinated control of both data center and network resources in order to provide adaptive data delivery services and adequate service experience to cloud users. In this regard, flexible optical networks can play a fundamental role in telco clouds to effectively address bandwidth requirements of elastic data center operations. This paper presents a cross-functional orchestration platform able to coordinate the provision of cloud-based services with multi-granular data delivery services across flexible optical network. The architectural design is described along with orchestration policies that are compared in terms of blocking ratio of service requests against the level of utilization of network links
