Goals of this draft


To describe various scenarios of the usage of a
logical interface in a LMA side and a MN side


Scenarios 1
-

LMA acknowledges each physical interface
of a MN


Scenarios 2
-

LMA acknowledges logical interface of a
MN


Scenarios 3
-

All home network prefixes are shown to
host IP stack


Scenarios 4
-

Only one home network prefix is shown to
host IP stack

3

Motivation (1/3)


Logical interface


used to hide the change of network interface from the
upper host IP layer


Multihoming support of PMIPv6


LMA MUST allocate a mobility session for each of the
attached interfaces


The LMA MAY allocate more than one home network
prefix for a given interface of the mobile node


The LMA MUST allow for a handoff between two
different interfaces of a mobile node

Motivation (2/3)


With logical interface, in LMA point of view;


Scenario
-
1: If link
-
layer identifier of each physical
interface is delivered to a LMA through PBU message


LMA

may acknowledge each physical interface and it allocates
mobility sessions for each interface and each mobility session
for the each physical interface is generated


Scenario
-
2: If link
-
layer identifier of logical interface is
delivered to a LMA through PBU message


LMA may acknowledge only a logical interface and it allocates
mobility sessions for a logical interface and mobility session
for a logical interface is generated



4

Motivation (3/3)


With logical interface, in MN point of view


Scenario
-
3: If a LMA allocates multiple HNPs to a
multiple interfaces MN, these multiple home network
prefixes are totally shown to the host IP stack


Scenario
-
4: Even though a LMA allocates multiple
HNPs to a multiple interfaces MN, only one home HNP
is shown to the host IP stack


If a logical interface hides the change of interfaces and also can
hide the change of home network prefixes

Next Step?


Is describing various scenario of the usage of
logical interface in PMIPv6 necessary?


Or should we target on a specific scenario?


Scenario
-
1 vs. Scenario
-
2


Scenario
-
3 vs. Scenario
-
4


Is there interest in WG?
