7. jkchoi@icu.ac.kr 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. jkchoi@icu.ac.kr 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
