Dynamic Virtual GMPLS-Controlled WSON Using a Resource Broker with a VNT Manager on the ADRENALINE Testbed
Optical network virtualization involves the dynamic provisioning of dedicated (virtual) networks over the same physical optical infrastructure, which is attracting a lot of attention from network infrastructure providers, with the purpose of offering their Infrastructure as a Service (IaaS). The authors present a resource broker with a VNT manager which dynamically deploys virtual GMPLS-controlled WSON networks. Virtual optical links are constructed by grouping established light-paths which are managed by the VNT manager. They evaluate the performance of the resource broker in the ADRENALINE test-bed highlighting the service deployment time.
