论文摘要
网络虚拟化是一种在共享基板上同时运行多个异质体系结构的方法。网络虚拟化的主要问题是将虚拟网络映射到基板网络。如何在映射阶段管理底物资源将在改善基础架构资源的使用中发挥有效的作用。在网络虚拟化中使用基于软件的网络将控制逻辑与数据分开为新技术，从而在这种情况下导致了有效的资源管理。在本文中，已经提出了一种基于软件的网络方法来有效地网络虚拟化和管理基础架构资源。它通过基础架构资源的动态资源管理来优化映射功能。我们已经在控制器中添加了一个模块，以动态管理资源。将根据许多成功的请求和到达时间插槽来完成初始映射以到达新请求。在到达n请求之前，将不会在交换机中编写规则来确定它们。如果需要在N时间窗口中进行一些重新映射，则控制器可以进行重新映射，并将最终结果发送到交换机以编写流量规则。模拟已经使用NS2模拟器根据不同的评估标准（例如接受率，平均链接利用率，成本和延迟）进行了进行。关键字：网络虚拟化，基于软件的网络，虚拟网络映射，基板网络，虚拟网络。
Network virtualization is a way to simultaneously run multiple heterogeneous architectures on a shared substrate. The main issue in network virtualization is mapping virtual networks to substrate network. How to manage substrate resources in mapping phase will have an effective role in improving the use of infrastructure resources. Using software-based networks in network virtualization which separates control logic from data as a new technology, has led to efficient resource management in this context. In this article a software-based network approach has been presented to network virtualization and manage infrastructure resources efficiently. It optimizes mapping function by dynamic resource management of infrastructure resource. We have added a module in the controller to manage the resources dynamically. An initial mapping will be done for arriving new requests based on number of successful requests and arriving time slots. They will not be finalized by writing the rules in the switches before arriving n requests. If some remapping during the n time window is needed, remapping can be done by the controller and the final results are sent to the switches to write the flow rules. The simulation has been done using NS2 simulator showed based on different evaluation criteria such as acceptance rate, average link utilization, cost and delay. Keywords: network virtualization, software based network, Virtual network mapping, substrate network, Virtual network.
