Federated networks represent a remunerable operational way, allowing federated partners to increase their incomes through a sharing resource process. They have been primarily used in the context of cloud computing; nowadays, they are also used to provide connectivity services, like virtual private networks. However, providing such a service by using standard technologies in federated networks requires a nonnegligible effort from different points of view (e.g., configuration effort). In this paper, we propose an software‐defined network (SDN)–based framework aiming at overcoming limitations in currently adopted best practices to issue virtual private networks in federated networks. Relying on the SDN architecture, we propose a method allowing federated providers to quickly and easily create federated networks, reducing unneeded costs (e.g., new hardware), and a way for customers to fast‐access federated services, without any explicit actions from providers. We evaluate our framework by using SDNetkit. We focus on analyzing the impact of our implementation on both control and data plane, in terms of number of control messages exchanged in the network and size of the forwarding tables, respectively.

软件定义的联邦网络中的多提供商虚拟专用网框架

联盟网络是一种有偿运营方式，允许联盟伙伴通过共享资源过程增加收入。它们主要用于云计算环境中。如今，它们还用于提供连接服务，例如虚拟专用网。但是，通过在联邦网络中使用标准技术来提供这种服务需要从不同角度进行不可忽略的努力（例如，配置努力）。在本文中，我们提出了一个基于软件定义网络（SDN）的框架，旨在克服当前采用的最佳做法中的局限性，以便在联合网络中发布虚拟专用网络。依靠SDN架构，我们提出了一种方法，允许联盟提供商快速，轻松地创建联盟网络，从而减少不必要的成本（例如，新硬件），以及一种客户快速访问联合服务的方式，而无需提供商采取任何明确的措施。我们通过使用SDNetkit评估我们的框架。我们分别根据网络中交换的控制消息数和转发表的大小，重点分析实现对控制平面和数据平面的影响。
