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
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
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
