This paper aims at defining the right set of primitives a NIC shall expose to efficiently offload the QUIC protocol. Although previous
work already partially tackled this problem, it has only considered one specific aspect: the crypto module. We instead dissect different QUIC
kernel to userspace communication, the crypto module and the packet reordering algorithm are CPU hungry and often the cause of
application performance degradation. We use those findings to define an architecture for offloading QUIC and discuss the associated
challenges.
