“…Hence, legacy IPv4 network has greater energy waste problem because of its complexity in management, control, and operation (Bruschi et al, ). Several studies have been performed for the energy aware routing scheme to minimize the energy consumption and carbon footprint reduction to show that IPv6 and SDN have greater flexibility towards green networking (Chabarek et al, ; Gaddour, Koubâa, & Abid, ; Gesi, ; Giroire, Moulierac, & Phan, ; Hu, Luo, Wang, & Deng, ; Maaloul et al, ; Ruiz‐Rivera, Chin, & Soh, ; Saad, Chauvenet, & Tourancheau, ; Tuysuz, Ankarali, & Gözüpek, ; Zhu, Liao, De Laat, & Grosso, ). SDN devices being programmable and controllable, network switches and links can enter into low power state in the sleep mode and the device architecture can be designed to have actual load based proportional energy consumption (Assefa & Ozkasap, ).…”

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.

“…As a matter of fact, the transmission delay is related to bandwidth, which has been considered during the process of modeling data forwarding ability. In addition, the energy‐efficient SDN has attracted much attention from the world‐renowned research teams and scholars in recent years . Given this, we regard energy consumption as the computation attribute of communication cost.…”

In recent years, Content‐Centric Networking (CCN) has been considered as a novel promising paradigm for the future Internet, shifting from provider‐driven end‐to‐end communication mode to interest‐driven content retrieval communication one, which greatly depends on routing technology. In spite of this, CCN routing always faces two significant issues, ie, scalability and large‐scale deployment, which restrict the increasing development of CCN but can be addressed by introducing the ideas of Software‐Defined Networking (SDN) and community (domain) division. However, the current routing proposals on the integrating with SDN, community division or their combination, still have some limitations to be improved. Therefore, in this paper, we propose a novel and intelligent CCN Routing mechanism based on SDN and Community Division (CRSCD). At first, a community division scheme based on eigenvetor centrality and label propagation is proposed to help content retrieval. Then, for each divided community, we deploy an SDN controller which consists of two tables, ie, content index and community topology to help manage the global network view. Finally, a comprehensive routing mechanism including intracommunity routing based on Ant Colony Optimization (ACO) and intercommunity routing based on interaction frequency is devised. The proposed CRSCD is implemented over Cogent topology, and the experimental results demonstrate that the introduction of SDN and community division can accelerate content retrieval greatly and has better performance than the previous work.

“…Hence, it would be interesting to optimize the number of rules installed in forwarding devices. TCAM-based energy-aware SDN issues received significant attention as shown in [31]. Some of the works address the problem of rule placement without considering energy savings, see [32], [33] and [34].…”

Soft-Defined Networking (SDN) is a new approach that enables operators to easily manage all the network elements.In this paper, we address the problem of energy-aware routing in SDN-based carrier-grade Ethernet networks. Our approach is based on turning off network nodes and links to reduce energy consumption, while respecting the rule space capacity for each Openflow switch, and maintaining an allowable maximum link utilization. The problem of identifying the optimal set of network elements to be turned off is NP-hard. We first present an exact model based on an Integer Linear Programming formulation for the problem. Then, we describe a set of firstfit heuristic algorithms suitable for large-sized networks. The exact and heuristic approaches are tested on SNDlib-based instances. Experimentations show the efficiency of both exact and heuristic methods for different network topologies. In particular, our heuristic algorithms are able to achieve a good balance between energy consumption, resource utilization, and network performance.
