“…Considering access network only, the node represents the CPE and end access switches, while link represents wireless and wired links. The power of switch in the active mode varies due to change in its active ports and traffic load (Rodrigues et al, ). Hence, considering the basic formulation of power consumption in ISP network by Chiaraviglio, Mellia, and Neri (), the total power consumption by an ISP's end access network having two modes (active and sleep) of operation can be formulated as:

{(P_{total})}_{access} = \sum_{i = 1}^{ns} ({}, P_{{sleep}_{i}} + x_{i} ((), P_{{active}_{i}} - P_{{sleep}_{i}}) \times \sum_{j = 1}^{ks} ((), f_{{italictr}_{j}} \times P_{{italicpc}_{j}})) + \sum_{k = 1}^{nl} x_{k} P_{{link}_{k}}

where “ns” represents the number of nodes, “ks” represents the number of active ports of that node, “nl” represents the number of links, “f tr ” represents per active‐port load proportional traffic demand, and P pc represents the port power coefficient.…”

The use of information and communication technology (ICT) has resulted in significant impacts on social welfare, economic growth, transparency, and good governance in developing countries like Nepal. Due to the diverse geographic and economic situations, ICT network and service expansions throughout Nepal have been becoming quite challenging. Private network operators mostly have confined their services to urban areas. Nepal Telecommunications Authority (NTA) collects 2% royalty form Internet Service Providers (ISPs) and Telecom Operators as Rural Telecommunications Disbursement Fund (RTDF) to enhance ICT services to rural Nepal. Broadband expansion projects initiated by utilizing RTDF to expand ICT infrastructure throughout Nepal are expected to have considerable societal and economical transformations in the rural communities of Nepal. This paper not only presents the current ICT deployment scenario of Nepal but also studies design, analysis, and evaluation of green networking that leverages both software defined networking (SDN), and Internet Protocol version 6 (IPv6)-aka Software Defined IPv6 (SoDIP6)-for energy efficient networking, robust services, and sustainable ICT ecosystem for developing nations like Nepal. We evaluate the SoDIP6 network by considering a typical ISP with end access networks and present benefits and recommendations. Experimental results show that the proposed SoDIP6 network help significantly reduce the energy consumption and carbon footprint leading to overall economic benefits to service providers and the society. Furthermore, energy-saving practices through SoDIP6 networks and some policy directions to the government to focus on green networking considering sensitivity of climate change and global warming impact in the mountainous and developing countries like Nepal are presented.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…The work of Rodrigues et al 15 integrates 3 different protocols that operate at different network levels to improve the energy efficiency of an SDN network. These protocols are adaptive link rate, 16 synchronized coalescing, 17 and sustainability-oriented network management system, 18 which work at chip, node, and network level, respectively.…”

“…Clearly, energy-efficient proposals for hybrid IP/SDN networks will achieve lower power saving outcomes at early stages of the migration process than the optimal ones obtained when they are run on fully deployed SDN networks. [13][14][15][16][17][18][19][20][21][22] To the best of our knowledge, the closest work to our approach is Wei et al, 24 where the power consumption of a hybrid IP/SDN network is minimized by finding the optimal setting of OSPF link weight and splitting ratio on SDN nodes. In particular, IP routers perform shortest path routing by optimizing OSPF link weights, and SDN nodes fulfil multipath routing with traffic flow splitting through the action of the controller.…”

The emerging software-defined networking (SDN) paradigm introduces new opportunities to improve network performance due to the flexibility and programmability provided by a logically centralized element named controller.However, a rapid adoption of the full SDN architecture is difficult in the short term due to economic and technical reasons. This paper faces the SDN nodes replacement problem during the transition from traditional IP networks to fully deployed SDN networks. Six different replacement methods are proposed to select the most appropriate set of traditional IP nodes to be upgraded to SDN-enabled switches at a particular transition stage. To show the effectiveness of the proposed methods, they have been applied on an optimization problem currently studied by the research community: the power consumption problem. An integer linear programming formulation is presented to solve it and a genetic algorithm is evaluated through simulations on realistic network topologies. Results highlight that energy-efficiency in hybrid IP/SDN networks can be significantly improved by only replacing a reduced number of IP nodes.

Resumen-La demanda de cursos de redes a distancia y semipresenciales está aumentando día a día en el sector de las tecnologías de la información y comunicación (TIC). Para realizar este tipo de cursos se precisa tener laboratorios específicos que permitan la conexión remota, por lo que requieren que estén continuamente encendidos para su acceso. Este hecho implica un consumo de energía bastante elevado, aun cuando el laboratorio no está siendo utilizado. Además, el sector de las TIC es uno de los que presenta un consumo mayor a nivel mundial. Al ver la necesidad de controlar el consumo de estas instalaciones, se propone la implementación de un laboratorio real energéticamente eficiente, controlado mediante una red definida por software (SDN) de gestión. Se basa en un controlador y switches Openflow que en función del tipo de peticiones que reciba por parte de los usuarios remotos, distribuirá, de manera eficiente, el acceso a los diferentes laboratorios. Para ello, se implementa un algoritmo de control que ejecuta el controlador, y éste, actuará sobre diversos switches OpenFlow. Estos switches son los encargados de encender y apagar las diversas secciones de los laboratorios. Finalmente se simula el funcionamiento de este laboratorio para los 2 tipos de consumo de energía, es decir, usando la red de gestión SDN y cuando los laboratorios permanecen encendidos a la espera de las peticiones de conexión por parte de los usuarios. Los resultados demuestran que para el funcionamiento del laboratorio durante una semana, podríamos obtener un ahorro de energía cercano al 47%.Palabras Clave-OpenFlow, prácticas de redes, eficiencia energética, redes definidas por software (SDN), Green Networking.
