Abstract

Nowadays, Internet services demand for the mobilization of computing and storage resources located in proximity of the final users, and for the support of an agile and programmable network infrastructure. This calls for a holistic vision in which control, management, and optimization of both computing and networking resources are combined, resulting in a progressive blur of the capabilities of the latter towards the edges of the transport segment. However, due to its multi-provider nature, the Internet itself is the main obstacle to this change. In such a context, Network Virtualization (NV) and Software Defined Networking (SDN) solutions can enable business opportunities and provide technical benefits for the operators managing the different domains of a transport infrastructure. In this paper we discuss in detail the technical challenges and outline potential architectural approaches exploiting the above mentioned solutions to provide edge-to-edge virtualization, abstraction, control, and optimization of heterogeneous transport networks composed of both packet- and circuit- switched technologies.

异构传输网络中的边缘到边缘虚拟化和编排

如今，Internet服务需要动员位于最终用户附近的计算和存储资源，并需要支持敏捷和可编程的网络基础设施。这需要一个整体的愿景，在这个愿景中，计算和网络资源的控制、管理和优化相结合，导致后者的能力逐渐模糊到传输部分的边缘。然而，由于其多提供者的特性，互联网本身是这种变化的主要障碍。在这种情况下，网络虚拟化(NV)和软件定义网络(SDN)解决方案可以为管理传输基础设施的不同域的运营商提供商机和技术优势。在本文中，我们详细讨论了技术挑战，并概述了利用上述解决方案提供由分组交换和电路交换技术组成的异构传输网络的边缘到边缘虚拟化、抽象、控制和优化的潜在体系结构方法。
