MaxNet is a redesigned TCP Internet congestion control framework based on explicit signaling of congestion information from routers to hosts. MaxNet achieves provable high performance with the following key features:

Equilibrium properties:

  • Efficient utilization of network capacity [1]
  • Fairness of source rates (weighted Max-Min fairness) [1]

Dynamic properties:

  • Provable stability for any topology [2]
  • Fast dynamics: Low latency and jitter, fast utilization of link capacity as flow starts [3]

Implementation [4]:

  • Fully distributed, no per-flow information at router.
  • Very low router buffer requirement.
  • 23 bit signal in header allows 32 to 1015 bps (one million Gbps) per source with 0.001% accuracy.
  • Only 2 integer operations per packet on router fast-path (max & add).
