Green IP over WDM Optical Network Design for Mixed Line Rates and Limited Transmission Reaches

چکیده
This paper considers mixed-line-rate (MLR) technology to design a green IP over WDM optical network. We develop a node-arc-based mixed integer linear programming (MILP) optimization model and propose a simple heuristic to configure the mixed-line-rate network. Results indicate that for the test scenarios considered, more than 48% power consumption can be saved compared with the single-line-rate (SLR) case. Keywords—mixed line rate; green optical network; node-are model; limited transimission reach

Power-Aware Logical Topology Optimization for IP-over-WDM Networks Based on Per-Lightpath Power Consumption Model
This paper considers the problem of logical topology optimization in an IP-over-WDM network, with the objective to minimize the total power consumption used to support the given traffic demands. While there are several power consuming devices in a backbone WDM network, it is assumed that major power consumption occurs at IP router ports, which are termination points of optical connections or li...
متن کاملEnergy Minimized design of Mixed Line Rate IP-over-WDM Network
Power consumption in IP-over-WDM networks has become a major concern, more so due to rapidly evolving data intensive applications. Increasing power consumption also increases the environmental cost (carbon emission). Carbon emissions are the result of power generation using non-renewable (traditional hydrocarbons) energy resources. Usage of non-renewable energy resources (such as hydrocarbons, ...
متن کاملEnergy optimization in IP-over-WDM networks
The energy crisis and environmental protection are gaining increasing concern in recent years. ICT (Information and Communication Technology) has a significant impact on the total electricity consumption all over theworld. Telecomnetworks, being an important part of ICT, consume significant energy since more network equipment is deployed annually. Specifically, in IP-over-WDM networks, energy i...
متن کاملEnergy-Efficient Opaque IP over WDM Networks with Survivability and Security Constraints
Mixed deployment of sleep-enabled and non-sleep-enabled router cards is suggested at each node of an IP over WDM network along with survivability and security constraints. This is used to design a green network which is observed to reduce energy consumption (by up to 28% for an example network) compared to a network where the router cards are not sleep-enabled. OCIS codes: (060.4250) Networks; ...
متن کاملRobust IP Backbone Network Utilizing WDM Optical Paths*
A wavelength division multiplexing (WDM) optical path-based Internet protocol (IP) backbone network is proposed as a cost-effective way of realizing robust IP-over-photonic systems. The WDM optical path is based on WDM transmission and wavelength routing. Between end-to-end IP backbone routers, the WDM optical path, a fat and robust optical pipe, is defined across photonic transport systems (PT...
