Computer Network is a collaboration platform for digital gadgets. Virtualization is abstracting layers from underlying Architecture. Virtualization platform provides flexibility, green resource usage and fast deployment of the carrier. Integration of Computer Network and Virtualization Platform Create Network Virtualization Platform. Software-Defined Network (SDN) Provide dynamic and scalable networking offerings to Business Environments Cloud Network and Data Centers. SDN is controlling network infrastructure with the control plane. Security is a challenging problem for the network. SDN comes with Network Programmability and automation. SDN has an advantage, but it contains a new safety issue. SDN is focused on network safety data plane and control. Security Challenges in SDN is Control Plane, Data Plane Attacks. In Controller Layer Attacker at controller Layer, an routing, visitors filtering denying, or allowing unnecessary site visitors. Control plane assault used to drop or lack of manage over traffic policy and Quality of carrier control. Data Plane Attack Attacker can create DOS Denial of Service.

Atualmente, a Internet faz parte do cotidiano das pessoas, sendo um meio de comunicação essencial. Contudo, esta sofre de limitações que a impedem de garantir Qualidade de Serviço (Quality of Service QoS) aos usuários. Portanto, os Provedores de Internet (Internet Service Providers ISPs) necessitam evoluir, adicionando novas tecnologias e estratégias de gerência, tais como Virtualização de Redes (Network Virtualization NV), Redes Definidas por Software (Software Defined Network SDN) e Virtualização de Funções de Rede (Network Function Virtualization NFV), criando a idéia de Provedores de Internet do Futuro (Future Internet Service Providers FISPs). Sendo assim, os FISPs fatiam os recursos de rede dentre os clientes e os serviços prestados, onde torna-se crucial um algoritmo para definir a alocação das fatias de rede. Adicionalmente, os FISPs devem considerar a utilização elástica dos recursos de rede pelos clientes ao decorrer do dia. Dentro deste contexto, este artigo apresenta o algoritmo Per Time Calculation (PETIC) para definir o fatiamento da rede baseado nos requisitos de largura de banda dos clientes. Os resultados obtidos sugerem que o algoritmo proposto define fatias de rede mais adequadas que as abordagens existentes.
