Integrated IT and network orchestration using OpenStack, OpenDaylight and active stateful PCE for intra and inter data center connectivity

摘要

We present an integrated IT and network orchestration using OpenStack for the deployment of virtual machines within DCs and OpenDaylight SDN controller for end-to-end connectivity provisioning across Ethernet networks (Intra-DC) and a GMPLS-enabled WSON with an active stateful PCE (Inter-DC).
