Backgrounds

BcN (Broadband convergence Network)NGN driven by Korean Government

NGcN(Network Generation convergence Network): previous nameConvergence

Wire & Wireless Broadcasting & Communication Voice & Data

Anytime, Anywhere, Anyone, Anydevice, Anymedia, Anyservice En route Path toward Ubiquitous world

IPv6 is one of the core initiatives for BcNAddressability, Auto Configuration, Mobility, QoS ... Mandated by even DoD this year.

New Life Pattern

What is New Life Pattern using New Residential Network EnvironmentLocale not only of Fixed House but also of Nomadic HouseRoles not only for Home but also for OfficeShould consider the network for Personal Area Env.

For Wearable electronic devices For Personalization with Accompanying Env. (Ex, Music, Temperatu

re, Illumination, Humidity, Preferred Desktop Menu..)Location independent access to HomeMay be Used for even Public (Ex, Real time Regional Power Con

sumption Distribution Map) Means Moving Life

Network Mobility(2)

Host Mobility vs. Network Mobility Host Mobility

Mobile node itself only MN changes its point of attachment Handled by Mobile IP WG in IETF

Network Mobility Entire Network mobile as a unit and

attached to Internet via a MR One or more IP-subnets One or more MRs

MR changes its point of attachment Node behind MR don’t change their

own point of attachment But the Protocol is based on ones of

Host Mobility Handles by NEMO WG in IETF

Network Mobility(3)

Benefits of Network Mobility over Host Mobility Only the Mobile Router maintains Internet Access Even with Standard IPv6 Node behind the MR

Means No Mobility support Node More distinct requirement than ones of Host Mobility

regarding Handover Watching a movie while walking? Or Watching movie in a train?

More Scenarios Nested Mobility: A subset of Mobile Network is itself mobile

Visiting Mobile Nodes: A PDA in a train Mobile IP-subnets: A PAN in a train

Multi-Homing A Mobile Network connected to the internet via several

Interfaces

Network Mobility(4)

NEMO WG Initiated with the problem of Mobile IP not suitable for Network

MobilityCreated in Oct. 2003Stepwise Approach

Basic Support: short term solutionQuick solution, even if not efficientMaintain session continuity to all MNNsSolution: Bidirectional tunnel between MR and HA

Extended Support: long termOptimal routing between arbitrary CNs and MNNsSolution: more investigation in the solution space is needed

Network Mobility Current Issues

Basic Solution: using Bi-directional TunnelingTo be explained later

Resembles Mobile-IPMR registers gets 1 CoA (or More) and register it with HAHA records a network-specific route instead of home-specific ro

Not Optimal solution, but guarantee mobile networks supported with minimal workPermanent connectivity to all MNNsMobility management transparency to MNNsNumbers of BU minimized (1 per MR not LFN)

Extended Solution(2)

Considerations for Optimal RoutingBinding Update to CN?

Who issues BU?MNN or MRLFN is never mobility-considered.

Currently BU is not piggybacked in MN in Mobile IPv6 MR issues first instead of MN when the first packet from

NN?Source routing chain for nested mobile network?

RSVP-like Binding Update?BU accumulation for every en-route MR?

Can the prefix delegation scheme used for this? All the MNN

Nobody knows the solution currently!

17

New Paradigm for Network Switch

Major Issue until nowWhich Way the packet/frame should forward?When the packet/frame should forward or is it discard?But never consider the payload not only touch but even lookup!

New Paradigm: Disruptive TechnologyContents Awareness

The needs for payload lookup ability The Higher Hardware capacity( Ex, EZ chip: string parsing NP)

How about Contents customization for user? How about Real time Consumer edge Transcoding for streaming

This issue may be needed or not for Optimal routing in Mobile Network

18

Conclusion and Future works

Network Mobility is core issue for New Residential Network.

For Real Network Mobility, Optimal Routing should be considered soon.

Should we break the taboo? the payload manipulation Future works for consideration

Haw can we deploy the ‘Contents awareness’?Can Router issues Signaling packet for its node?

BcN & Residential Network & IPv6Should be merged together for Real Ubiquitous World
