BB-Gen: A Packet Crafter for Data Plane Evaluation
Resumo
With the advent of research on fast path packet processing, traffic generator tools witnessed many entrants with features ranging from supporting list of protocols, analyzing network traffic to measuring throughput and latency of packets. While approaching towards feature completeness, the tools are becoming more complex every time making it difficult to port, manage, and use. BBGen with a sole focus on simplicity complements other traffic generators instead of trying to replace them. BB-Gen is a simple CLI-based packet crafter to generate packet flows formatted as PCAP files. The tool supports different standard protocols and creates the necessary traces for network function configuration and testing. It allows creating PCAPs for worst and best case scenarios with all unique flows or following flow distributions published elsewhere. In this demo, we feature BB-Gen as used by the MACSAD development team to test P4-based software switch pipelines.
