Abstract

Traditional Internet routing is simple, scalable and robust, but cannot provide perfect QoS support due to the current completely distributed hop-by-hop routing architecture. Software defined networking (SDN) opens up the door to traffic engineering innovation and makes possible QoS routing with a broader picture of overall network resources. We further argue that SDN can provide more opportunity for the network users to make their own routing selections with network programmability. In this paper, we propose OpenMCR, a general framework for network users to make their own choice of routing given various requirements. OpenMCR provides routing subject to several additive QoS constraints, which is NP-hard when the number of constraints is two or more. By composing various necessary conditions with different path extension schemes, our platform can customize routing solutions for each network user based on their own requirements. Through experiments in an SDN emulated environment, we evaluate multiple aspects of OpenMCR, demonstrate its effectiveness compared with several baselines and validate our theoretical analysis.

您希望您的包裹如何投递?支持sdn的QoS路由开放平台

传统的Internet路由具有简单、可扩展性强、鲁棒性强的特点，但由于目前完全分布式的逐跳路由架构，无法提供完善的QoS支持。软件定义网络(SDN)为流量工程创新打开了大门，并使QoS路由与整体网络资源的更广泛的画面成为可能。我们进一步认为，SDN可以为网络用户提供更多的机会，让他们自己选择具有网络可编程性的路由。在本文中，我们提出了OpenMCR，一个通用框架，供网络用户根据不同的需求自行选择路由。OpenMCR提供受几个附加QoS约束的路由，当约束的数量为两个或更多时，这是NP-hard。通过将各种必要条件与不同的路径扩展方案组合在一起，我们的平台可以根据每个网络用户的需求定制路由解决方案。通过在SDN仿真环境中的实验，我们评估了OpenMCR的多个方面，并与几个基线进行了比较，验证了我们的理论分析。
