grout

grout stands for Graph Router. In English, "grout" refers to thin mortar that hardens to fill gaps between tiles. grout is a DPDK based network processing application. It uses the rte_graph library for data path processing. Its main purpose is to simulate a network function or a physical router for testing/replicating real (usually closed source) VNF/CNF behavior with an open-source tool. It comes with a client library to configure it over a standard UNIX socket and a CLI that uses that library. The CLI can be used as an interactive shell, but also in scripts one command at a time, or by batches.
