Routing in Fat Trees (RIFT) Key/Value Topology Information Elements Structure and Processing

The RIFT (Routing in Fat Trees) protocol allows for key/value pairs to be advertised within Key-Value Topology Information Elements (KV TIEs). The data contained within these KV TIEs can be used for any imaginable purpose. This document specifies behavior for the various Key-Types (i.e., Well-Known, OUI, and Experimental) and a method to structure corresponding values. It also defines a Well-Known Key Sub-Type used for testing tie-breaking behavior.
