基于软件的数据中心网络多路径RDMA解决方案
A Novel Software-based Multi-path RDMA Solutionfor Data Center Networks
摘要：
在本文中，我们提出了Virtuoso，一个纯粹的基于软件的多路径RDMA解决方案的数据中心网络（DCN），有效地利用丰富的多路径拓扑结构的负载均衡和可靠性。作为一个在用户空间运行的“中间件”库，Virtuoso采用了三种创新机制来实现其目标。与现有的基于硬件的MP-RDMA解决方案相比，Virtuoso可以很容易地部署在具有现有RDMA的DCN中。它还将路径选择和负载均衡机制与硬件功能相结合，允许DCN操作员和应用程序根据需要采用最佳机制（如“插件”软件库模块）来做出灵活的决策。我们的实验表明，Virtuoso是能够充分利用多个路径，可以忽略不计的CPU开销
英文摘要：
In this paper we propose Virtuoso, a purely software-based multi-path RDMA solution for data center networks (DCNs) to effectively utilize the rich multi-path topology for load balancing and reliability. As a "middleware" library operating at the user space, Virtuoso employs three innovative mechanisms to achieve its goal. In contrast to existing hardware-based MP-RDMA solution, Virtuoso can be readily deployed in DCNs with existing RDMA NICs. It also decouples path selection and load balancing mechanisms from hardware features, allowing DCN operators and applications to make flexible decisions by employing the best mechanisms (as "plug-in" software library modules) as needed. Our experiments show that Virtuoso is capable of fully utilizing multiple paths with negligible CPU overheads
