Abstract

We present our observations deploying SDN-enabled solutions in operational Tier-1 carrier networks. This includes technical and operational issues that are of prime importance to service providers. Specifically, we focus on two archetypal customer use cases that we have observed from the point of view of optical transport applications. In addition, other key aspects such as the role of embedded control plane in SDN are discussed. Development models used by service providers and how this plays a crucial/symbiotic role between the vendor (enhancing platform data & control plane features) and the service provider (rolling out SDN-enabled services) are considered. We conclude with a synopsis on the state-of-affairs, and the role of standardization in the SDN ecosystem.
揭开SDN光传输网络的神秘面纱:现实世界的部署和见解
我们介绍了在运营的第1层运营商网络中部署支持sdn的解决方案的观察结果。这包括对服务提供商至关重要的技术和操作问题。具体来说,我们将重点关注我们从光传输应用的角度观察到的两个原型客户用例。此外,还对嵌入式控制平面在SDN中的作用等关键方面进行了讨论。服务提供商使用的开发模型,以及它如何在供应商之间发挥关键/共生作用(增强平台数据);控制平面特性)和服务提供商(推出支持sdn的服务)都要考虑在内。最后,我们简要介绍了SDN的现状,以及标准化在SDN生态系统中的作用。
