软件定义网络(SDN)为运营、管理和部署通信网络以及克服传统网络的许多长期存在的问题提供了一种新的方式。然而，由于缺乏可行的增量部署路径，以及市场上支持SDN的设备相对不成熟的现状，SDN的广泛采用尚未发生。虽然不断发展的软件交换机可能会缓解基于硬件的商业SDN产品的运营问题，即标准合规性滞后、性能倒退和可扩展性差，但它们无法与成本效益和端口密度相匹配。在本文中，我们提出了一种新的无害SDN交换机设计，通过在单独的软件交换机组件中模拟OpenFlow交换机操作系统，无缝地将SDN功能添加到传统网络设备中。这样，无害解决方案可以快速轻松地进入SDN，将软件交换机的快速创新和升级周期与基于硬件的设备的端口密度和成本效益结合在一起，形成一个完全透明的数据平面和供应商中立的解决方案。与现有交钥匙供应商SDN解决方案相比，无害的SDN部署的初始支出要小一个数量级，同时为较小的企业带来匹配甚至更好的数据平面性能。
Software-Defined Networking (SDN) offers a new way to operate, manage, and deploy communication networks and to overcome many long-standing problems of legacy networking. However, widespread SDN adoption has not occurred yet due to the lack of a viable incremental deployment path and the relatively immature present state of SDN-capable devices on the market. While continuously evolving software switches may alleviate the operational issues of commercial hardware-based SDN offerings, namely lagging standards-compliance, performance regressions, and poor scaling, they fail to match the cost-efficiency and port density.In this paper we propose HARMLESS, a new SDN switch design that seamlessly adds SDN capability to legacy network gear, by emulating the OpenFlow switch OS in a separate software switch component. This way, HARMLESS enables a quick and easy leap into SDN, combining the rapid innovation and upgrade cycles of software switches with the port density and cost-efficiency of hardware-based appliances into a fully dataplane-transparent and vendor-neutral solution. HARMLESS incurs an order of magnitude smaller initial expenditure for an SDN deployment than existing turnkey vendor SDN solutions while it yields matching, or even better data plane performance for smaller enterprises.
