SUPERp: Scale UP EtherRnet Protocol
summary
Proposes SUPERp, an Ethernet-based Scale Up protocol for RMA and HPC ops that compresses IP into a SunH network header with 16-bit addresses (fits ~65k hosts) and shrinks IPv4-like headers from ~20 bytes to ~8 bytes, targets ~50–100 ns class latency, uses per-packet sequence numbers, a 16‑byte transport header and 8‑byte transaction header, and supports ordered/unordered delivery and bitmap SACKs. Implements a proof‑of‑concept in XDP2 with a common source that compiles to eBPF or P4 hardware (specs on GitHub / IETF draft).
