RIFT Wiki Page

RIFT is specialized, dynamic routing protocol for Clos and fat-tree networks and its' variants. The protocol

(1) deals with fully automated construction of fat-tree topologies based on detection of links,

(2) minimizes the amount of routing state held at each level,

(3) automatically prunes and load balances topology flooding exchanges over a sufficient subset of links,

(4) supports automatic disaggregation of prefixes on link and node failures to prevent black-holing and suboptimal routing,

(5) allows traffic steering and re-routing policies,

(6) allows loop-free non-ECMP forwarding,

(7) automatically re-balances traffic towards the spines based on bandwidth available and finally

(8) provides mechanisms to synchronize a limited key-value data-store that can be used after protocol convergence to e.g. bootstrap higher levels of functionality on nodes.
