A Novel Framework for Guaranteed Serivice Provisioning in Optical Network

This paper proposes a novel framework for the provisioning of guaranteed services in slot-based optical networks. We use the time-domain wavelength interleaved network (TWIN) architecture for the proof of concept. In this paper, we propose a framework comprising a control plane and a data plane. While the main functions of the control plane include admission control and capacity allocation to source-destination node pairs, the data plane functions settle operational issues such as traffic aggregation, buffering, and scheduling. We present a simple slot collision-resolution algorithm in the control plane and conduct extensive simulations to show the performance of the algorithm. In the data plane we show by means of the service curve theory that the aggregation and scheduling mechanism is able to provide an efficient per-flow guarantee
