  1. Virtual Interface Support for IP Hosts<draft-yokota-netlmm-pmipv6-mn-itho-support-03> Hidetoshi Yokota KDDI Lab Sri Gundavelli Cisco Tran Minh Trung ETRI Yong-Geun Hong ETRI Kent Leung Cisco IETF #77 Anaheim, March 2010

  2. Introduction “draft-yokota-netlmm-pmipv6-mn-itho-support-02” + “draft-trung-netext-virtual-interface-01” “draft-yokota-netlmm-pmipv6-mn-itho-support-03” New charter item is created: “hiding access technology changes from host IP layer” Two I-Ds merged into one: Discusses applicability to not only inter-tech handoff, but also multihoming and flow mobility to cover the scope of the charter Main focus is on the host side (L3 and under)

  3. Virtual interface approach (review) Application Application layer TCP/UDP Transport layer IP stack (IPv4/IPv6) IP layer Virtual interface Datalink layer I/F I/F Physical layer PHY1 PHY2 Focus of this draft

  4. Routing with virtual interface Application Application layer TCP/UDP Transport layer IP stack (IPv4/IPv6) IP layer Policy Routing Table VIF1 Datalink layer IF1 IF2 Physical layer WLAN WiMAX

  5. Multihoming case LMA’s Binding Table LMA PCoA-1 PCoA-2 MAG1 MAG2 (WLAN) (WiMAX) HNP-1 HNP-2 IF1 (WLAN) IF2 (WiMAX) IP1=HNP-1:IID-1/128 LL-ID: MAC-1 Virtual I/F IP2=HNP-2:IID-1/128 Upper layer MN-ID: MN-1

  6. Inter-technology handoff case LMA’s Binding Table PCOA-2 5 LMA PCoA-1 PCoA-2 MAG1 MAG2 (WLAN) (WiMAX) handoff HNP-1 HNP-1 IF1 (WLAN) IF2 (WiMAX) LL-ID: MAC-1 Virtual I/F IP1=HNP-1:IID-1/128 Upper layer MN-ID: MN-1

  7. Flow mobility case LMA’s Binding Table (flow-1) (flow-2) PCOA-2 5 LMA PCoA-1 PCoA-2 MAG1 MAG2 (WLAN) (WiMAX) flow-2 handoff HNP-1 HNP-2 HNP-2 IF1 (WLAN) IF2 (WiMAX) IP1=HNP-1:IID-1/128 LL-ID: MAC-1 Virtual I/F IP2=HNP-2:IID-1/128 Upper layer MN-ID: MN-1

  8. Summary and proposal • Virtual interface approach to multihoming, inter-technology handoff and flow mobility • Focuses on the host side (on and under L3) • There are still missing pieces, which may be covered by this or other drafts… • Propose to move this I-D to the baseline WG document for the logical interface over multiple physical interfaces
