摘要

本文介绍了动态交通管理（DTM）的概念、实现和评价。这种管理机制最大限度地降低了域间链路上的流量传输成本。它适用于批量和百分之95美元的关税。DTM对域间链路上的流量变化做出动态反应，将部分流量（可管理流量）从一个链路转移到另一个链路。管理机制以分布式方式工作。它需要运营商，即互联网服务提供商之间的合作，接收和产生流量。ISP之间的通信通过SDN控制器（域间SDN）来实现。DTM已被应用于位于不同ISP域的数据中心（DC）的云间通信。此外，它与云无关，即DTM不让云服务提供商（CSP）参与管理程序。在试验台上进行的评估表明，DTM能够将过境交通的ISP成本降低29%。

Dynamic Traffic Management for SD-WAN Inter-Cloud Communication

This article introduces the concept, implementation and evaluation of Dynamic Traffic Management (DTM). This management mechanism minimizes traffic transfer costs on inter-domain links. It works for volume and $95^{th}$ percentile tariffs. DTM reacts dynamically to traffic changes on inter-domain links shifting some part of traffic (manageable traffic) from one link to another. The management mechanism works in a distributed way. It requires cooperation between operators, namely Internet Service Providers (ISPs), receiving and generating traffic. Communication between ISPs is realized by SDN controllers (inter-domain SDN). DTM has been applied to inter-cloud communication for Data Centers (DCs) located in different ISP domains. Moreover, it is cloud-agnostic, i.e., DTM does not engage Cloud Service Providers (CSPs) into management procedures. Evaluation performed in the testbed shows that DTM is capable of decreasing ISP costs of transit traffic up to 29%.
