O consumo de energia dos ambientes de virtualização de rede (NVEs) tornou-se um problema crítico. Neste artigo, nos concentramos na redução do consumo de energia de comutação de dados do NVE. Primeiro analisamos a energia de comutação de dados do NVE. Em seguida, propomos uma realocação dinâmica de recursos de link virtual com eficiência energética (eEVLRR) abordagem para NVE. eEVLRR realoca dinamicamente os recursos de substrato com eficiência energética (recursos s) para links virtuais com alterações dinâmicas de recursos s incorporáveis para economizar energia de comutação de dados. Para evitar interrupções de tráfego durante a realocação, projetamos um modelo de encaminhamento baseado em sessão de aplicação de camada cruzada para eEVLRR que pode identificar e encaminhar cada fluxo de transmissão de dados ao longo do caminho inicial de transporte de dados do substrato especificado até o final, sem interrupções de tráfego. Os resultados das avaliações de desempenho mostram que eEVLRR não apenas garante que os recursos s alocados de links virtuais sejam continuamente eficientes em termos energéticos para economizar energia de comutação de dados, mas também tem impactos positivos na taxa de aceitação da rede virtual, nas receitas e na utilização dos recursos s.

Abstract: The energy consumption of network virtualization environments (NVEs) has become a critical issue. In this paper, we focus on reducing the data switching energy consumption of NVE. We first analyze the data switching energy of NVE. Then, we propose a dynamic energy efficient virtual link resource reallocation (eEVLRR) approach for NVE. eEVLRR dynamically reallocates the energy efficient substrate resources (s-resources) for virtual links with dynamic changes of embeddable s-resources to save the data switching energy. In order to avoid traffic interruptions while reallocating, we design a cross layer application-session-based forwarding model for eEVLRR that can identify and forward each data transmission flow along the initial specified substrate data transport path until end without traffic interruptions. The results of performance evaluations show that eEVLRR not only guarantees the allocated s-resources of virtual links are continuously energy efficient to save data switching energy but also has positive impacts on virtual network acceptance rate, revenues and s-resources utilization.
