Introduction

Usage of IoT (Internet of Things) rapidly increases in our time Demand for delay-sensitive real-time applications will increase Requirement of seamless handoff to ensure no loss packets during IP address configuration

slide-3
SLIDE 3

Demonstration of IPv6 Handover Process

Figure A1

slide-4
SLIDE 4

Current solutions

Various protocols improve the efficiency of IPv6 Handover Therefore improving the speed

  • f IPv6 Handover

Proposed Solution

Change of the environment

  • f the program

Increase in efficiency - administrative processes can be bypassed

slide-5

Research Objectives

Work on IPv6 Handover process in a Linux Environment 1

02 01

Determine suitable parameters to ensure possible IPv6 Handover

slide-6
SLIDE 6

Methodology

  • bypass the System Command step
  • functions in the API to proceed directly to the Kernel
slide-7
SLIDE 7

1. Deciding on Final Kernel Libraries

slide-8
SLIDE 8

Allows the Kernel’s routing tables to be read or altered Used to transfer information between the Kernel and user-space processes

  • 1. rtnetlink
  • 2. netlink
slide-9
SLIDE 9
  • 2. Addition and deletion of

Multiple IPv6 addresses

  • RTM_NEWADDR
  • RTM_GETADDR
  • RTM_DELADDR

Using kernel library functions:

  • RTA_LENGTH
  • Prefix length
  • ADD/DEL IP address

Attributes of the address:

slide-10
SLIDE 10

Adding of Attribute: RTA_LENGTH Payload of header (to delete address)

slide-11
SLIDE 11

Message in API containing attributes

slide-12
SLIDE 12
  • 3. Addition of address labels

Two types of addresses

1. Primary (only 1)

  • where packets are sent and

downloaded

  • 2. Deprecated
  • where packets are downloaded
slide-13
SLIDE 13

Should an IPv6 Address be preferred, it will have a preferred lifetime. Should an IPv6 Address be deprecated, it will have an expired lifetime.

slide-14
SLIDE 14

Adding of attribute containing flags

slide-15
SLIDE 15
  • 4. Addition of Routing
  • Routing establishes the route taken by

packets to their destination address

Function type RTM_ROUTE is used, with payload containing routing table related information.

slide-16
SLIDE 16

Modification of Routing Table:

  • Different set of attributes

1. Destination Address

  • 2. Interface
  • 3. Route type, etc.

SLIDE 17

Payload of RTM_ROUTE Message

Results and Discussion

1

slide-19
SLIDE 19
  • 1. Successful addition and

deletion of IPv6 Addresses

  • Different functions, causing there to be

modifications to payload

slide-20
SLIDE 20

Successful addition of IPv6 addresses

slide-21
SLIDE 21

Successful deletion of IPv6 addresses

slide-22
SLIDE 22
  • 2. Successful labelling of

primary or deprecated addresses

slide-23
SLIDE 23
slide-24
SLIDE 24
  • Valid lifetime of each address label is set to be forever
  • Preferred lifetime of a deprecated address is set to be 0.

Attributes for this request

slide-25
SLIDE 25
  • 3. Successful identification
  • f routing attributes
slide-26
SLIDE 26
  • Attributes needed in payload for routing

modifications include:

1. Destination Address

  • 2. Interface
  • 3. Route type
  • 4. Prefix length
  • 5. Appropriate flags , etc.
slide-27

Conclusion

1

slide-28
SLIDE 28

Successful choosing of Kernel Libraries Successful adding and deleting of IPv6 addresses on a single interface Successful labelling of addresses Successful identification of routing attributes

slide-29
SLIDE 29

These findings work towards enabling Linux to be a viable platform for IPv6 Handover processes in the future.
