Status

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>


Example qos control plane intra domain

Example QoS Control Plane – Intra-Domain

  • Horizontal protocol depends a lot on the direction and the purpose, such as Diameter, RADIUS, SNMPv3, etc.


Example qos control plane inter domain

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


Conclusion

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?
