What it covers

  1. 4.1Adaptive routing: per-packet spraying and its eligibility rules
  2. 4.2Why spraying needs a SuperNIC: reordering and direct data placement
  3. 4.3Telemetry-based congestion control: three loops, not one
  4. 4.4Programmable congestion control with DOCA PCC
  5. 4.5Multiplane fabrics and multi-tenant performance isolation
