Flow Binding Extensions to PMIPv6IETF 84

draft-sarikaya-netext-fb-support-extensions-02


Problem statement

Problem Statement

LMA initiated flow mobility is not possible in PMIPv6 of RFC 5213

PMIPv6 Multihoming extension (RFC 5213) treats each interface independently

LMA does not know about different interfaces MN may have, LMA does not manage bindings from different interfaces of the mobile node in an integrated fashion

Each interface creates a different independent mobility session at the LMA, just like an interface from another MN

MN uses different source addresses when sending packets over these interfaces

Flow mobility is not possible


Draft sarikaya netext fb support extensions

draft-sarikaya-netext-fb-support-extensions

We have a simple solution:

The bindings in binding cache from each interface are kept together so that the flows can be moved among interfaces.

MN may have as many binding entries as it has active interfaces, one “home” and many “secondary”, flagged “H” or “S”

A new H flag in HNP option is set to ‘H’ for home and ‘S’ for other interfaces

Incoming flows always directed to home interface, flow state set at LMA to direct flows to different active interfaces

MN always sends non-local packets with source address assigned from HNPs of its home “H” interface


Draft sarikaya netext pmipv6 shared link 01

draft-sarikaya-netext-pmipv6-shared-link-01

Wi-Fi or IEEE 802.11 provides a shared link

PMIPv6 is designed for point-to-point links, i.e. cellular links

Why do we need to run PMIPv6 on Wi-Fi?

The answer is SaMOG or s2a interface for FMC

Issues: MAG sends RA with HNPs for MN to FF02::1 which could be received by other MNs

serious

MN may receive NS messages from nodes other than MAG due to IPv6 solicited-node multicast address may map to more than one nodes

Less probable

Multicast data using MLD: problems TBD
