2 Two Layer View of IPv6 Signaling Interworking Existing Networks (IPv4/MPLS, PSTN/ISDN, Cellular, IMT-2000) Existing Networks (IPv4/MPLS, PSTN/ISDN, Cellular, IMT-2000) Existing Networks (IPv4/MPLS, PSTN/ISDN, Cellular, IMT-2000) Existing Networks (IPv4/MPLS, PSTN/ISDN, Cellular, IMT-2000) IPv6 Signaling for NTLP (IPv6 Transport Network) IPv6 Signaling for NTLP (IPv6 Transport Network) IPv6 Signaling for NSLP (IPv6 Signaling Network) IPv6 Signaling for NSLP (IPv6 Signaling Network) Control-Plane User-Plane Existing Networks (IPv4/MPLS, PSTN/ISDN, Cellular, IMT-2000) Existing Networks (IPv4/MPLS, PSTN/ISDN, Cellular, IMT-2000) IPv6 Signaling for NTLP IPv6 Signaling for NTLP IPv6 Signaling for NSLP IPv6 Signaling for NSLP Control-Plane User-Plane IPv6 Signaling for NTLP IPv6 Signaling for NTLP IPv6 Signaling for NSLP IPv6 Signaling for NSLP Control-Plane User-Plane

3 Signaling Interworking between IPv6 and IPv4 IPv4 Ocean (MPLS) IPv6 Island RSVP-TE/CR-LDP Signaling (Core Network) IPv6 Signaling (Access/Metro/Home Network) Flow Label FEC IPv6 Signaling (Access/Metro/Home Network) IPv6 Ocean IPv4 Island (MPLS) IPv4 Island (MPLS) IPv6 Signaling (Core Network) RSVP/RSVP-TE Signaling (Access/Metro/Home Network) FEC Flow Label RSVP/RSVP-TE Signaling (Access/Metro/Home Network)

4 Signaling Interworking between IPv6 and Existing Telco Network PSTN/ISDNCellular/IMT-2000 IPv6 Signaling Telephone Signaling (No.7, DSS-2) Physical/Logical Circuit Flow Label Cellular/IMT-2000 Signaling PSTN/Cellular/ IMT-2000 Network IPv6 Island Telco Signaling IPv6 Signaling Flow Label Physical/Logical Circuit IPv6 Signaling IPv6 Ocean

5 Support of Domain Service Model on Optical Transport Network Optical Transport Network IPv6 Client Network O-UNI/GMPLS Signaling IPv6 Signaling Flow Label Optical Label IPv6 Signaling

6 Requirements for IPv6 Signaling  Backward Compatibility with IPv4 Signaling and MPLS/GMPLS Signaling RSVP for IPv4 Network RSVP-TE/LDP/CR-LDP for MPLS Signaling Extensions of RSVP-TE/CR-LDP for Optical Network (GMPLS) No.7 Signaling for Telephony and Cellular Phone, etc.  Traffic Parameters for End-to-End QoS Provisioning Bandwidth or resource reservation of IPv6 transport network By Mapping between Flow Label and FEC By Mapping between Flow Label and Existing Circuit/Path

7 Other Considerations  Delivery of signaling messages both for IPv6 Signaling Network and IPv6 Transport Network Using Router Alert Option Next Header for signaling  Support of VPN service in IPv6 network Security  using the Authentication Header and the Encapsulating Security Payload Header of IPv6 Group management (VPN ID)  using ICMPv6  Make Use of IPv6 Features Explicit route setup Using IPv6 routing header for explicit route Using Explicit route object/TLV of existing signaling protocol (RSVP-TE, CR-LDP) Hop by Hop Option Header (Router Alert Option) Mobility support

8 Next Steps & Discussion  Supporting QoS Signaling in IPv6 network Backward Compatibility with IPv4 Network and Existing Wireline/Wireless Telco Network Need of signaling interworking between IPv6 and other networks  Is this proposal appropriate for the item of NSIS WG ? If so, we will develop the requirements document for signaling interworking between IPv6 and other networks
