VON/K: A Fast Virtual Overlay Network Embedded in KVM Hypervisor for High Performance Computing

摘要

With the emergence of cloud computing, it is possible that the Virtual Machines (VMs) hosting High Performance Computing (HPC) applications seamlessly migrate between distributed cloud resources and tightly-coupled cluster resources. However, the performance of existing virtual computing environment integrated with VMs and overlay networks cannot support the high-performance distributed computing. In this paper, we describe the design and implementation of a virtual overlay network, VON/K, which is integrated with Kernel-based Virtual Machine (KVM). VON/K has negligible latency and bandwidth overheads on lGbps Ethernet networks, providing near-native access to high performance networks.
