Instant 100G emulated network testbed in a pizza box

P7 (P4 Programmable Patch Panel): an instant 100G emulated network testbed in a pizza box

About P7

Options to validate a network topology, including the link metrics, are traditionally based on virtual environments (e.g., Mininet), limiting the experiments with transmission speeds over 10Gbps. By leveraging P4 programmability and new generation hardware, P7 comes as an alternative to define emulation characteristics of the links and represent a network topology with high fidelity and computation power using a single physical P4 switch (e.g., Tofino). It is possible to emulate network topologies using recirculations, port configurations, different match+action tables, and even DAC cables. What is more, we can connect physical servers to inject traffic to the topology.

This is still a work in progress. Feedback is welcome!

Requirements

• git
