The most important features of software defined networks are related to resource virtualization and centralized optimal control that is fully programmatically realized. In turn it gives rise to development of mathematical model which allows to find the optimal solution. On the other hand important role in optimization process belongs to criterion of optimality (objective function). Taking into account...
Problem of energy saving in telecom industry can be partially solved by using IP-over-DWDM architecture. In the paper mathematical model for cross-layer optimal resource allocation in such networks according to power objective function is presented. In order to simplify process of numerical solving partitioning scheme is offered. Within the scheme subtasks of routing at IP level and wavelength assignment...
Internet traffic is growing exponentially day by day. Internet consumes a large amount of energy about 1–2% of world's total electricity. One of the challenging constraints for the growth of internet will be its energy consumption. An approach to decrease energy consumption of internet is to deploy optical technologies based on WDM. Power consumption can be minimized by applying power saving strategies...
We consider the power-efficient design of an Internet protocol (IP)-over-wavelength division multiplexing (WDM) network, tackling the problem of installing optical and IP layer equipment to satisfy traffic requirements. We take into account routing constraints and consider a comprehensive set of realistic scenarios defined by network topology, traffic matrix, and power consumption values ofnetwork...
We propose a novel energy-efficient and survivable routing algorithm addressing the trade-off caused by conflicting objectives of energy saving and survivability, i.e. energy-efficient routing tends to pack while survivable strategies try to spread the traffic.
Since its emergence the internet has been a significant part of today's modern living. Defined by its interconnections and routing policies, it has fuelled increased demands for provisioning of new more advanced services that are able to dynamically react to changes within the network. These services however, lead to enormous energy consumption in contrast to a global drive for a greener environment...
