Torii HLMAC
Elisa Rojas, Guillermo Ibáñez · 2011
This paper describes Torii-HLMAC, a scalable, fault-tolerant, zero-configuration data center network fabric architecture (currently under final evaluation) as a full distributed alternative to Portland for similar multiple tree (fat tree) network topologies. It uses multiple, fixed, tree-based positional MAC addresses, used for multiple path table-free forwarding. Addresses are assigned by simple extension of the Rapid Spanning Tree Protocol. Torii-HLMAC enhances the Portland protocol advantages of scalability, zero configuration and high performance and adds instant path recovery, distributed address assignment. ARP broadcast may use ARP Proxy.
