Experimental evaluation of a VON Resource Broker and Compositor for deployment and performance of virtual GMPLS control planes

Abstract

We present a Virtual Optical Network (VON) Resource Broker and Compositor architecture to dynamically configure and deploy independent instances of virtual GMPLS-controlled WSON. The VON Resource Broker consists of four blocks: resource manager, VON controller, resource allocator and resource configurator. In this paper, we evaluate the impact of the proposed VON Resource Broker on the provisioning of virtual GMPLS control planes and the performance of provisioning lightpaths within a virtual control plane through experimentation in the ADRENALINE Testbed. The obtained results show the trade off between the diminution of blocking rate of VON requests, through the provision of more virtual resources for the virtual control planes, and the deterioration of the virtual control plane performance (e.g. higher setup delay and higher blocking probability while provisioning lightpaths).
