GIST State Machine <draft-ietf-nsis-ntlp-statemachine-02> Tseno Tsenov Hannes Tschofenig Xiaoming Fu Cedric Aoun Elwyn Davies

Draft overview Better understanding of GIST protocol operation from implementers' point of view State and its transition diagrams rather than pure text Current version is based on v01.txt with ID-nits FSMs for two peering GIST nodes

Next Steps Provide concrete use examples of how GIST delivers messages and manages internal state State machine Message flows in different situations Fleshing out the conceptual data structures a bit more Eventually, serve as GIST protocol implementation guide
