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

In this paper, we provide future storage system insights by using a new methodology that leverages an objective, multi-dimensional statistical technique to extract data access patterns from network storage system traces.
Enterprise storage systems are facing enormous challenges due to increasing growth and heterogeneity of the data stored. Designing future storage systems requires comprehensive insights that existing trace analysis methods are ill-equipped to supply. In this paper, we seek to provide such insights by using a new methodology that leverages an objective, multi-dimensional statistical technique to extract data access patterns from network storage system traces. We apply our method on two large-scale real-world production network storage system traces to obtain comprehensive access patterns and design insights at user, application, file, and directory levels. We derive simple, easily implementable, threshold-based design optimizations that enable efficient data placement and capacity optimization strategies for servers, consolidation policies for clients, and improved caching performance for both.
