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

This paper is the first to evaluate the feasibility of deploying QUIC, a new UDP-based transport protocol currently undergoing IETF standardization, directly on resource-constrained IoT devices. It quantifies the storage, compute, memory and energy requirements of the Quant QUIC stack on two different IoT platforms, and finds that a minimal standards-compliant QUIC client currently requires approximately 58 to 63KB of flash, around 4KB of stack, and can retrieve 5KB of data in 4.2 to 5.1 s over 0-RTT or 1-RTT connections, using less than 16 KB of heap memory (plus packet buffers), less than 4 KB of stack memory and less than 1.09 J of energy per transaction.
