Use Cases

IO Visor has been in use across a variety of use cases. The following are a few examples:


BCC or BPF Compiler Collection is a toolkit leveraging eBPF for creating kernel based tracing programs. Functions include kprobes, uprobes, tracepoints, USDT probes and more. Some use cases can be found below:

IO Visor Project enables advanced networking functions (L3, NAT, …) to be implemented in-kernel fully distributed across N compute nodes and chained in-kernel to create any arbitrary “network topology” moving past a virtual/physical appliance type of deployment.

IO Visor is enabling container technologies such as Docker, Mesos, and Kubernetes for virtual networking, security, and policy enforcement. New projects are emerging that are leveraging eBPF and XDP for containers.

Cilium is an experimental project using eBPF and XDP to provide fast in-kernel networking and security policy enforcement for containers. For more information, please visit the Cilium Github.

IO Visor Project enables security functions (micro-segmentation, security groups and firewalls) to be implemented in-kernel and distributed, hence providing the optimal enforcement point for application traffic without the need to hairpin traffic through security appliances. An example of its application to a security problem is seccomp (SECure COMPuting), which implements fencing of applications, by leveraging eBPF as the backend.
