One of the main goals of creating Future Networks is to reduce the energy for their operation through the use of various energy-saving technologies. The most important components of existing and future networks are Passive Optical Networks (PON), which are widely used for building broadband access networks. The methodology for measuring the power consumption of passive optical network equipment with time division multiplexing TDM-PON is discussed in the article. It is based on the materials of ITU-T Recommendations Y.3021 and Y.3022. Estimations of possible energy savings in the GPON network based on OLT and ONU equipment of the Russian company Eltex are obtained with the use of the doze mode and cyclic sleep mode.
Connection setup with guaranteed quality of service (QoS) in the optical virtual private network (OVPN) is a major goal for the network providers. In order to support this we propose a QoS based OVPN connection set up mechanism over WDM network to the end customer. The proposed WDM network model can be specified in terms of QoS parameter such as blocking probability. We estimated this QoS parameter based on the hose-model OVPN. In this mechanism the OVPN connections also can be created or deleted according to the availability of the wavelengths in the optical path. In this paper we have considered the impact of the number of wavelengths on the computation of blocking probability. The goal of the work is to dynamically provide a best OVPN connection during frequent arrival of connection requests with QoS requirements.
