Open-source IO visor eBPF-based packet tracing on multiple network interfaces of Linux boxes

With the growing popularity of cloud-leveraged infrastructure and services, the creation and operation of multiple virtualized boxes over a single physical box is increasing rapidly. It is however becoming difficult to maintain transport performance and security with an increasing number of inter-connections among them. To address this issue, in this paper, we utilize the eBPF-based packet tracing of open-source IO Visor project to monitor the inter-connections among Linux boxes. By enabling the tracing capability at multiple network interfaces, we validate it experimentally over Linux-based SmartX boxes with open-source KVM hypervisors and Docker containers.
