  1. NSIS in an off-path world –the control plane Hannes Tschofenig Robert Hancock IETF 64

  2. Status • NSIS was designed to focus on path-coupled signaling • but the design separates discovery from message delivery. • and the design allows many applications • If you would like to use an off-path or a control plane solution then you could use NSIS in the subsequently described way: <draft-hancock-nsis-pds-problem-01.txt>

  3. Example QoS Control Plane – Intra-Domain • Horizontal protocol depends a lot on the direction and the purpose, such as Diameter, RADIUS, SNMPv3, etc.

  4. Example QoS Control Plane – Inter-Domain • Conceptually, the existing discovery procedure just learns the next NSIS-aware device along the path. • Control messages may take a zig-zag path

  5. Conclusion • The NSIS protocol suite, as a generic signaling solution, is well-suited for a number of environments and usage scenarios • Advantage of using NSIS (for the scenarios we investigated): • For intra- and inter-domain signaling reuse QoS signaling and authorization work • Intra- and inter-domain signaling is can use the same signaling protocol (it is just QoS signaling along a number of nodes) • Discussions about NSIS usage in the ITU-T and ETSI-TISPAN in progress (as candidates for off-path signaling usage) • If we engineer it for DiffServ properly then the engineering will be right. • How are the DCPEL problem statements and requirements consistent with this discussion?

  6. Acknowledgments • We would like to thank the following individuals for contributing to this talk: • Attila Bader • Xiaoming Fu • Georgios Karagiannis • John Loughney • Allison Mankin • Jukka Manner
