Rethinking Polling Efficiency in Service Core Network Stacks
Matheus Stolet, Simon Peter, Antoine Kaufmann
Idle network service cores are treated as wasted compute. This assumption motivates increasingly sophisticated mechanisms that reclaim idle cores at microsecond timescales. We argu…
Chamelio: A Fast Shared Cloud Network Stack for Isolated Tenant-Defined Protocols
Matheus Stolet, Simon Peter, Antoine Kaufmann
Conventional cloud network virtualization sends packets through multiple guest and host layers, inflating CPU cost and tail latency. Shared host datapaths collapse this layering in…
Tail Contagion: Sub-microsecond Time Protection in Shared Software Network Datapaths
Matheus Stolet, Liam Arzola, Simon Peter +1
Shared software datapaths underpin modern datacentre networking. They implement mechanisms such as virtual switching, network virtualisation tunneling, or reliable transport, and e…
Presto: A Match-Action TCP Stack for the Terabit Era
Rajath Shashidhara, Antoine Kaufmann, Simon Peter
We present Presto, the first TCP stack that delivers ASIC-class performance and energy efficiency on programmable Reconfigurable Match-Action Table (RMT) pipelines, providing flexi…
