QoS Based OVPN Connection Set Up and Performance Analysis
Authors: , ,
Abstract: Due to high demand of optical virtual private network (OVPN) connection setup with guaranteed quality of service (QoS) requirement, it is necessary to provide such application by the provider network. In order to support this we propose a QoS based OVPN connection set up mechanism over WDM network to the end customer, which also maintains the minimum blocking probability. The proposed WDM network model can be specified in terms of QoS parameters such as bandwidth and delay. We estimated those QoS parameters based on available resources and QoS requirements in terms of quality factor (Q-Factor). In this mechanism the OVPN connections also can be created or deleted according to the availability of the resources. In this paper we have considered the effect of polarization mode dispersion for the computation of Q-Factors which is prominent effect at high speed networks. The goal of the work is to dynamically provide a best OVPN connection during frequent arrival of connection requests with QoS requirements.
