Dragonet aims to bring the benefits of NIC hardware capability to applications in hardware agnostic way. It captures the complexity and diversity of NIC hardware by using modeling techniques. We have developed a DSL called Unicorn to simplify the writing these models. These models enables the system reason about the hardware capabilities and externalize the policies about NIC resource management. We have shown the usefulness of Dragonet by using it to manage hardware queues and filters across different NICs based on different application policies.
