  1. Inter-carrier NNI issues

  2. End-to-end services over multiple carrier domains • section 6.2 of "use case examples" • Which services ? • switched L1 connections only ? • all L1, L2, L3 services in NOBEL ?

  3. One carrier's perspective • We have control over our own network, but • we don't know the other networks • and we don't trust them • need well defined external interfaces

  4. Looking for standards • CP standards for transport networks ? • there are standards for the UNI • GMPLS was made for intra-domain • OIF E-NNI is explicitly intra-carrier • none of them is for the inter-carrier interface

  5. Analyse – what do we need? • Addressing • Signalling • Routing • which information? • full path or next hop? • avoid loops?

  6. Compare - what can we use ? • BGP ? • inter-carrier - but only for connectionless IP • E-NNI routing ? • for connections - but intra-carrier

  7. Things to look at • Assuming we can handle them in our network, what more is needed for inter-carrier ? • path diversity • protection / restoration • multilayer networks • (address mapping, security, policy control, business models)

  8. Our draft • rather general analysis • not applied to NOBEL scenarios yet • focus on switched L1 connections • intentions: • problem statement into D18 • results and conclusions into D25 • decisions into implementations.
