Quality of service estimation techniques for an optical virtual private network over wdm/dwdm network

Abstract: Quality of Service (QoS) in optical virtual private network (OVPN) is a demanding factor for communication network application. To provide desired QoS, the control plane in an all optical network (AON) has to be designed to maximize the quality of an OVPN connections (OVPNC). The AON is generally characterized by various network and physical layer parameters, which are used by the OVPN control manager (OVPNCM) for the estimation of quality factor (Q-Factor) for a set of possible OVPNC. It is observed that, not only the network layer parameters, but also the physical layer parameters called as physical layer impairments (PLIs) have impact on connection quality. In optical networks, the PLIs are incurred by non-ideal optical transmission media and accumulate along the optical connection. The overall effect of PLIs can be analyzed to determine the feasibility of quality based OVPNC. It is important to understand the process and provide the network as well as the PLI information to the OVPNCM and use this information efficiently to compute feasible connections along with Q-Factor values. Based on these, four different QoS estimation techniques have been proposed here.

Design and Analysis of QoS based Optimized Novel Optical Network Emulator for WDM Technology

Abstract: Network emulation is an important tool before doing experiments on real-time hardware. In case of unavailability of test-bed for optical networks such simulation platform are of great help. Accounting for system virtualization, which is currently being supported by modern operating systems, we present architecture for optical virtual private network (OVPN) emulation platform. In OVPN, Quality of Service (QoS) decides the performance of communication system. To get more accurate QoS, various network and physical layer parameters are considered and based of the highest QoS value and a threshold, best route calculation is derived. So it is thought of interest to develop a network emulation platform for QoS based OPVN path evaluation of optical networks. This tool can help with the calculations and estimations of path, way prior to real-time implementations and deployments.
