High-Performance Routing with Multipathing and Path Diversity in Ethernet and HPC Networks

Understand

The recent line of research into topology design focuses on lowering network diameter.

• Many low-diameter topologies such as Slim Fly or Jellyfish that substantially reduce cost, power consumption, and latency have been proposed.
• A key challenge in realizing the benefits of these topologies is routing.
• On one hand, these networks provide shorter path lengths than established topologies such as Clos or torus, leading to performance improvements.
